1997 drew to a close with a stronger than expected economy. The Dow closed at
7908.25 on December 31, an increase of 18.47% over 1996's year-end close. 1997
was also a year of solid returns for the fund accounts which comprise USAA
Life's Variable Annuity. An overview of historical performance, as well as
accumulation unit values, can be found on page A-6 of this Report. We issued an
additional 2,200 contracts bringing the total number of contractowners in 1997
to 5,873.


                                                            1997 ANNUAL REPORT 3

                              PRESIDENT'S MESSAGE

A TIME OF CHANGES
- -----------------

IMPROVEMENTS TO OUR CONTRACT

On January 1, 1998, USAA Life lowered Variable Annuity mortality and expense
(M&E) risk charges 38% in a continuing effort to provide greater value for
your long-term investments.  The M&E charge makes it possible for us to offer
the guaranteed death benefit which provides added protection and payout
options which can guarantee income for life.  These important benefits can
only be found in an annuity.

This reduction also allows more money to remain in the contract working for you.
At a quick glance, it may not seem like the lower M&E will make much of a
difference. But factor in another of the contract's more popular features - the
power of tax-deferred earnings - and you may find that the value of your
contract may increase substantially over time. To fully appreciate the impact of
this reduction, compare the contract's old pricing structure with the new lower
M&E based on the following example.

                             Initial
                            Investment     10 Years     20 Years     30 Years
                            ----------     --------     --------     --------
New Lower M&E (.65%)          $5,000       $ 88,131     $290,461     $780,550
Old M&E (1.05%)               $5,000       $ 86,120     $276,470     $720,932

This example updates the Nonqualified Variable Annuity Tax-Deferred Accumulation
graph as it appears on page 29A of your May 1,1997 prospectus. It assumes an
initial after-tax investment of $5,000 and that additional contributions of $400
are made at the beginning of each month. It further assumes a 10% rate of return
and reflects the deduction of all charges under the Variable Annuity contract.

This hypothetical example is for illustrative purposes only.

I think you will also be pleased to note that USAA Life's M&E charge is 42%
lower and total insurance charges are 41% lower than the average industry
contract.  Here are the details as they are reported by Morningstar, Inc., an
independent organization that monitors the performance of variable annuities:

                                                   Average
                                                  Industry
                                USAA Life         Contract 
                                ---------        ----------
M&E charge                         .65%             1.12%
- ------------------------------------------------------------
Administration Expense             .10               .14
- ------------------------------------------------------------
Distribution Expense                 0               .01
- ------------------------------------------------------------
Total Insurance Expenses           .75%             1.27%

TAXPAYER RELIEF ACT 
CREATES NEW
OPPORTUNITIES
- --------------------

At this time, I would also like to comment on the Taxpayer Relief Act of 1997
which provides Americans with new opportunities to save more for retirement.
Many will spend hours sorting through the details, evaluating options, and
changing strategies.  But before making any changes, you should also review
your objectives, risk tolerance, and retirement horizon which will provide
important information. Then when considering your options, don't forget these
features which can be found only with a Variable Annuity:

FLEXIBILITY. Money can be moved among the investment options without creating
a taxable event.

LESS RECORD KEEPING. The insurance company keeps tax basis records for your
annuity.  With other investments, your capital gains tax rate will depend on
the type of investment - when it was purchased and when it was sold - and you
will be responsible for keeping track of this information.

DEFERRAL OF TAXES. Over time, tax-deferred earnings and compounding may
significantly impact the value of your Variable Annuity. Even with the
lowering of capital gains tax rates, tax deferral is still a valuable feature
of annuities - especially for those who have longer retirement horizons.

ESTATE BENEFITS. Contract proceeds pass directly to your beneficiary avoiding
the cost and delays of probate.

LOOKING FORWARD
- ---------------

When the Variable Annuity was introduced three years ago, it was one of the
most competitive contracts available. In 1997, two investment options were
added to provide a broader range of diversification.  On January 1, 1998 we
improved the inherent value of the contract by reducing the M&E.  Later this
year, we plan to add even more options to the Variable Annuity's investment
lineup. The continued improvements we make, enable USAA Life to provide a
contract that offers greater value and more choices - important features you
require for your financial portfolio.

I encourage you to call a USAA Life Account Representative at any time if you
would like to discuss your financial situation, the details of our contract,
or information found in this Report.

1  Foreign investing is subject to additional risks, such as currency
   fluctuations, market illiquidity, and political instability, which are
   discussed in the Variable Annuity prospectus.

2  Total returns for periods of less than one year are not annualized. These
   returns are cumulative. 

   The AUV total return figures are computed in accordance with a formula
   prescribed by the Securities and Exchange Commission which includes the
   deduction of all contract charges. The performance data quoted represent past
   performance and do not represent the actual experience of amounts invested by
   a particular owner. Past performance is not a guarantee for future returns.
   An investment in the USAA Life VA Money Market Fund is neither insured nor
   guaranteed by the U.S. Government. There can be no assurance that the Fund
   will be able to maintain a stable net asset value of $1. The principal value
   contributed to the other fund accounts will fluctuate. When variable annuity
   accumulation units are redeemed, they may be worth more or less than their
   original cost.

                SEPARATE ACCOUNT OF USAA LIFE INSURANCE COMPANY

                         INDEPENDENT AUDITORS' REPORT

TO THE BOARD OF DIRECTORS OF USAA LIFE INSURANCE COMPANY AND
CONTRACTOWNERS OF THE SEPARATE ACCOUNT OF USAA LIFE INSURANCE COMPANY:

We have audited the accompanying statements of assets and liabilities as of
December 31, 1997, the related statements of operations for the year ended
December 31, 1997, the statements of changes in net assets for each of the
years in the two-year period ended December 31, 1997, and the unit value
information presented in note 5 for the periods ended December 31, 1997, 1996
and 1995 for the USAA Life Variable Annuity (VA) Money Market Fund Account,
USAA Life VA Income Fund Account, USAA Life VA Growth and Income Fund
Account, USAA Life VA World Growth Fund Account, USAA Life VA Diversified
Assets Fund Account, the Fund Account of the Capital Growth Portfolio-Class A
shares of the Scudder Variable Life Investment Fund (Scudder VLIF Capital
Growth Portfolio Fund Account), and the Fund Account of the American Growth
Portfolio of the Alger American Fund (Alger American Growth Portfolio Fund
Account); the statements of assets and liabilities as of December 31, 1997,
the related statements of operations, changes in net assets, and unit value
information presented in note 5, for the period from May 1, 1997
(commencement of operations) through December 31, 1997, for USAA Life VA
Aggressive Growth Fund Account and USAA Life VA International Fund Account,
available within the Separate Account of USAA Life Insurance Company. These
financial statements are the responsibility of the Separate Account's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform our audit to
obtain reasonable assurance about whether the financial statements are free
from material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
Investments owned at December 31, 1997 were verified by examination of the
underlying portfolios of the USAA Life Investment Trust or through
confirmation for the Scudder and Alger Funds' portfolios. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our 
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the aforementioned fund
accounts of the Separate Account of USAA Life Insurance Company as of
December 31, 1997, the results of their operations for the year or period
ended December 31, 1997, the changes in their net assets for each of the
years or periods in the two-year period ended December 31, 1997, and the unit
value information, as described in the first paragraph, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                                                               December 31, 1997

1)   ORGANIZATION

The Separate Account of USAA Life Insurance Company (the Separate Account) is
registered under the Investment Company Act of 1940, as amended, as a segregated
unit investment account of USAA Life Insurance Company (USAA Life), a wholly
owned subsidiary of United Services Automobile Association (USAA). 

The Separate Account is divided into nine variable annuity fund accounts, each
of which invests in a corresponding fund. The funds' objectives can be found on
page A-6 in this report.

The fund accounts available within the Separate Account include: the USAA
Life Variable Annuity (VA) Money Market Fund Account, USAA Life VA Income
Fund Account, USAA Life VA Growth and Income Fund Account, USAA Life VA World
Growth Fund Account,  USAA Life VA Diversified Assets Fund Account, USAA Life
VA Aggressive Growth Fund Account, and USAA Life VA International Fund
Account; the Fund Account of the Capital Growth Portfolio-Class A shares of
the Scudder Variable Life Investment Fund (Scudder VLIF Capital Growth
Portfolio Fund Account);  and the Fund Account of the American Growth
Portfolio of the Alger American Fund (Alger American Growth Portfolio Fund
Account).

The assets of the Separate Account are the property of USAA Life and are not
chargeable with liabilities arising out of any other business of USAA Life.

2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SECURITY VALUATION

Investments in mutual fund securities are carried in the Statements of Assets
and Liabilities at net asset value as reported by the fund. Gains or losses on
securities transactions are determined on the basis of the first-in first-out
(FIFO) cost method. Security transactions are recorded on the trade date.
Dividend income, if any, is recorded on ex-dividend date.

ANNUITY RESERVES

Annuity reserves for contracts in the payout phase are comprised of net
contract purchase payments, less benefits. These reserves are adjusted daily
for the net investment income and net realized gain (loss) and change in
unrealized appreciation/depreciation on investments. The mortality risk is
fully borne by USAA Life. The mortality calculations are based on the 1983a
Individual Annuitant Mortality Table at 3.0% interest. This may result in
additional amounts being transferred into the Separate Account by USAA Life
to cover greater longevity of annuitants than expected. Conversely, if
reserves exceed amounts required, transfers may be made to USAA Life.

DISTRIBUTIONS

The net investment income (loss) and realized capital gains of the Separate
Account are not distributed, but instead are retained and reinvested for the
benefit of unit owners.

FEDERAL INCOME TAX

Operations of the Separate Account are included in the federal income tax
return of  USAA Life, which is taxed as a "Life Insurance Company" under the
Internal Revenue Code.  Under current federal income tax law, no income taxes
are payable with respect to operation of  the Separate Account.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that may affect the reported amounts in the financial statements.

                         NOTES TO FINANCIAL STATEMENTS

         (CONTINUED)                                           December 31, 1997


3)   RELATED PARTY TRANSACTIONS

During the year ended December 31, 1997, advisory fees of  $597,854 were paid
or payable to USAA Investment Management Company (USAA IMCO) by the funds of
the USAA Life Investment Trust (the Trust). USAA IMCO is indirectly wholly
owned by USAA.  The funds' advisory fees are computed on an annualized rate
of 0.20% of the monthly average net assets for each calendar month of each
fund of the Trust except for the USAA Life VA Aggressive Growth Fund, which
accrues at an annualized rate of 0.50%, and USAA Life VA International Fund,
which accrues at an annualized rate of 0.65%.  USAA Life, out of its general
account, has agreed to reimburse USAA IMCO for the expenses it incurs in
rendering services to the Trust, but only to the extent these expenses exceed
the amount of the preceding advisory fees.

4)   EXPENSES

A mortality and expense risk charge is deducted by USAA Life from the
Separate Account on a daily basis which is equal, on an annual basis, to
1.05% of the daily net asset value of each variable annuity fund account. The
mortality risks assumed by USAA Life arise from its contractual obligation to
make annuity payments after the annuity date for the life of the annuitant in
accordance with annuity rates guaranteed in the contracts under distribution
options that involve life contingencies. USAA Life will also assume a
mortality risk by its contractual obligation to pay a death benefit upon the
death of an annuitant or contractowner prior to the Distribution Phase. The
expense risk assumed by USAA Life is that the costs of administering the
contracts and the Separate Account may exceed the amount recovered from the
contract maintenance and administration expense charge. The mortality and
expense risk charge is guaranteed by USAA Life and cannot be increased.
Effective January 1, 1998, this charge will be reduced to 0.65% of the daily
net asset value of each variable annuity fund account

The following expenses are charged to reimburse USAA Life for the expenses it
incurs in the establishment and maintenance of the Contracts and each variable
annuity fund account. USAA Life assesses each variable annuity fund account a
daily charge at an annualized rate of 0.10% of the average daily net assets of
each variable annuity fund account. Beginning on the first anniversary of the
effective date, and on each anniversary thereafter, a maintenance charge of $30
is deducted by USAA Life through a redemption of units from the accumulated
value of each contract. This charge will apply only while the contract is in the
accumulation phase. For the year ended December 31, 1997, contract maintenance
charges totaled $105,852 and such charges have been classified as contract
redemptions.

Any premium tax levied by a state or government entity with respect to the
Separate Account will be charged against the contract.

GENERAL DISCUSSION
by Portfolio Manager Pam Bledsoe

CURRENT MARKET CONDITIONS

With the Federal Reserve policymakers leaving rates unchanged since their
last action in March 1997, the money market arena has been uneventful.
Financial markets have focused on the crises in Asia and the potential impact
on the U.S. economy.  Growth in the U.S. is expected to slow during 1998 but
the economic expansion we have enjoyed since 1991 should continue.

STRATEGY

Our strategy is governed by the free-look period of the Variable Annuity.
This necessitates that we manage the VA Money Market Fund with relatively
short maturities, usually 7 to 16 days.  Principally the portfolio contains
three types of holdings: Variable Rate Demand Notes, U.S. Government Agency
Discount Notes, and Commercial Paper.  The mix among these types of holdings
will vary based on availability and cash needs.

INVESTMENT PROGRAM:

This Fund invests in a diversified portfolio of high-quality U.S. dollar-
denominated debt instruments that present minimal credit risk with remaining
maturities of 397 days or less.

An investment in this Fund is neither insured nor guaranteed by the U.S. 
Government and there is no assurance that the Fund will maintain a stable net 
asset value of $1.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Income Fund to two industry indexes which most closely resemble
the holdings of this Fund.  The Lehman Brothers Aggregate Bond Index is an 
unmanaged index made up of the government/corporate index, the mortgage-backed 
securities index, and the asset-backed securities index.  The Lipper A Rated 
Bond Fund Index is an unmanaged index made up of funds investing in corporate 
debt issues rated A or better or government issues.  The calculations for the 
Lehman Brothers and Lipper Indexes are based on a full calendar year in 1995,

GENERAL DISCUSSION
By Portfolio Manager J. W. Saunders, Jr.

MARKET CONDITIONS AND PERFORMANCE

The past six-months reporting period ending December 31, 1997 covered the
best bond market we have seen in two years.  Interest rates for the 30-year
U. S. Treasury bond (referred to as yield) declined from 6.82% on June 30,
1997 to 6.00% on December 31, 1997 as shown on the chart below.  When
interest rates (yields) decline, bond prices rise. I am pleased to report
that our VA Income Fund has performed very well during this period.  In fact,
for performance from January 1 through December 31, 1997, it ranked number 1
out of 29 funds in the Lipper Variable Annuity A Rated Bond Fund category.
The VA Income Fund average annual NAV total return was 11.60% compared to an
average of 9.24% for all variable annuity funds in Lipper's category.

             AN OVERVIEW (Continued)             DECEMBER 31, 1997

PORTFOLIO

The Federal Reserve appears comfortable with the outlook that inflation will
remain low, and this has calmed the bond market.  In light of this more
hospitable environment, we made some changes to the portfolio.  The common
stocks, primarily electric utilities which are sensitive to changes in
interest rates, were sold when their appreciating prices made their dividend
yields well below those available in bonds and preferred stocks.  Additional
investments were made in REIT preferred stocks at very attractive dividend
yields.  We also increased long U. S. Treasury bonds while somewhat reducing
the agency mortgage pass-through securities (FNMA and GNMA).  As of December
31, 1997, the Fund's portfolio mix as percentages of net assets was 29.5% U.
S. Treasury bonds, 45.8% agency mortgage pass-through securities, 10.4%
corporate bonds, and 13.0% preferred stocks.

OUTLOOK

Asian deflation, which is expected to deepen the U. S. trade deficit,
together with a shrinking U. S. budget deficit produces an interesting
supply/demand relationship for U. S. Treasury securities.  If there are more
U. S. dollars in Asian hands, and less of a need by the U. S. Treasury to
issue securities, then this could cause prices for U. S. Treasury securities
to rise (lowering interest rates) because of strong demand versus smaller
supply.  We expect that U. S. inflation will continue to experience a down
trend which could also lower interest rates.  In any event, the potential for
rising interest rates appears to be low for the time being.  We will continue
to seek a high level of income for the Fund to enhance the compounding of
potential returns which accrue through reinvestment of income.

DATA REPRESENTS THE LAST BUSINESS DAY OF EACH MONTH.

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Growth and Income Fund to the S&P 500 Index. The S&P 500 Index
is an unmanaged index representing the average performance of a group of 500
widely held, publicly traded stocks. It is not possible to invest directly in
the S&P 500 Index. 

The calculations for the S&P 500 Index are based on a full calendar year in
1995, whereas the calculations for the VA Growth and Income Fund are based on a
starting date of January 5, 1995-the inception date of this Fund. This
comparison is for illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Manager R. David Ullom

MARKET CONDITIONS

1997 proved to be the third straight year for more than 20% appreciation in
the U.S. stock market.  This trend was the result of continued earnings
growth on the part of most companies and the large net inflow of cash into
most equity investment vehicles.

As we enter 1998, two major themes appear to be driving valuations in the
U.S. stock market - the Asian economic crisis and the deflationary impact it
is having on other economies.  Although we have concerns regarding these two
factors, we believe that these market issues also present opportunities. This
follows with our investment strategy of focusing on stocks with poor investor
sentiment and low valuations.  Of course, we continue to analyze and
determine the ability of these value companies to recover and provide
normalized earnings and returns.

PORTFOLIO STRATEGIES

Not all of our holdings in the VA Growth and Income Fund kept pace with the U.S.
stock market's overall appreciation. Due to concerns surrounding the
deflationary impact of the economic crisis in Korea and southeast Asia, the
Fund's investment in commodity-oriented companies tended to perform poorly. Such
stocks included: Aluminum Co. of America (aluminum), Inco and Titaniam Metals
(metals/mining), Jefferson Smurfit and Weyerhaeuser (paper & forest products),
Sonat (natural gas), Unocal (oil-domestic integrated) and Apache Corp (oil & 
gas-exploration and production). However, we believe that fears of deflation are
overblown and that the shares of many commodity-oriented companies will recover.

groups that adversely impacted our performance included: Aetna (insurance-
life/health), Humana and Pacificare (healthcare-HMO's), Boeing
(aerospace/defense), Rockwell International (electrical equipment), B.F.
Goodrich (chemicals-diversified), Waste Management (waste management), May
Department Stores (retail-department stores), and Sears (retail-general
merchandising).

In 1997, all HMOs were impacted by problems controlling costs, Boeing had
production problems, and retailers reported sluggish sales growth. We believe
these conditions will begin to improve in 1998, thus the shares of companies in
these industries should return to normal valuation levels. Therefore, we will
continue to add to our exposure in HMOs, aerospace (Boeing), and selected
retailers.

The strongest performing stocks in the VA Growth and Income Fund continue to be
in the financial area (banks, insurance, and finance). Solid earnings growth and
share repurchase activity continued to fuel price appreciation for companies in
this area. Other groups with strong performance included: automobiles (Ford);
auto parts (Lear Corp.); telecommunications - long distance (AT&T and Sprint);
and telephones (Bell Atlantic and GTE Corp.). We believe that both auto parts
and telephones still do not reflect their earnings potential and will maintain
or increase our holdings in these industries. Conversely, we are becoming less
attracted to the shares of certain financial companies as their valuations have
improved dramatically over the past few years.

GENERAL DISCUSSION
by Portfolio Managers David Peebles, Albert C. Sebastian, and W. Travis
Selmier, II (Foreign Stocks) and R. David Ullom (Domestic Stocks)

MARKET CONDITIONS

The Fund's total return of 14.08% has outperformed the Lipper Global Funds
Average/1/ return of 13.26% for the one-year period ended December 31, 1997/2/.
As mentioned in the last two Reports, European markets have continued to perform
favorably while performance in emerging markets has been mixed. The
underweighted position in Japan has proven correct.

INTERNATIONAL

Europe - European markets provided favorable returns during the period
because of earnings growth, falling interest rates, and corporate
restructuring. Our holdings in Italy, Portugal, and the United Kingdom made
significant contributions to our European performance.  In fact, we increased
our exposure to the United Kingdom because of attractive valuations and a
stable, pro-business political environment.

Not less than 65% of the Fund's assets are invested in a diversified portfolio
of common stocks and other equity securities of both foreign and domestic
issuers representing at least three countries, one of which may include the
United States. The remainder of the Fund's assets may be invested in marketable
debt securities having remaining maturities of less than one year which are
issued or guaranteed as to both principal and interest by the U.S. government or
by its agencies.

           AN OVERVIEW (Continued)                 DECEMBER 31, 1997


Emerging Markets -- A series of currency devaluations in Asia has caused
turmoil and political disarray in the region.  This situation has brought
about a reduction in forecasted economic growth.  We believe the Brazilian
economy will be affected by the Asian slowdown; however, Argentina, Peru, and
Mexico continue to recover, driven by improving domestic economies.  In
Mexico's case, stronger economic ties with the U.S. are a driving force.  Our
expectations that political and economic reform would gain momentum in Russia
and Hungary proved correct as did our decision to slightly increase our
exposure in these countries.  Falling inflation and interest rates in Israel
have underpinned its market rally while the prospect of economic reform has
fueled Turkey's rise.

Japan -- Asia's currency crisis, combined with problems within the banking
system, has begun to take  its toll on the Japanese economy and stock market.
We believe that decisive action on restructuring Japan's tax and financial
systems is needed.  We continue to hold export-related stocks while looking
for quality domestic-related companies.  Our underweighted position in Japan
remains unchanged for the time being.

Other Markets -- Our overweighted position in Canada reflects the
attractiveness of the economy as well as our favorable outlook for Canadian
energy stocks.  In Australia, we have reduced equities to be more in line
with the world market's weighting.

UNITED STATES
Over the last six months, the allocation to domestic equities increased from
24.1% to 30.2%.  Domestic returns were hampered by investments in healthcare,
selected investments in electronics -- semiconductors, and computer software &
service. These investments represent quality companies whose shares should
return to favor during the upcoming months. Our investments in retailing and
oil related services provided positive returns to the Fund. And although we
believe both industries will continue to do well, we have slightly reduced
our exposure.

         AN OVERVIEW (Continued)                     DECEMBER 31, 1997


OUTLOOK

We will continue to favor European markets because of economic and political
stability, favorable valuations, and more predictable earnings growth.
Divergence in emerging markets should continue as most Asian markets remain
weak while many Latin American, Eastern European, and other markets are
likely to recover sooner.  We do not anticipate a marked improvement for the
Japanese economic picture and feel that it offers only selective
opportunities. While the U.S. market is fairly valued, it does offer political
and economic stability and continued prospects of lower interest rates.

Foreign investing is subject to additional risks such as currency fluctuations,
market illiquidity, and political instability which are discussed in the
prospectus. Since return on any investment is generally commensurate with risk,
investors should be aware of the potential volatility associated with foreign
markets

DATA REPRESENT THE LAST BUSINESS DAY OF EACH MONTH

The graph above compares the performance of a $10,000 hypothetical investment in
the USAA Life VA Diversified Assets Fund to two industry indexes and an
independent rating agency's average which most closely resemble the holdings of
this Fund.

The S&P 500 Index is an unmanaged index representing the average performance
of a group of 500 widely held, publicly traded stocks. It is not possible to
invest directly in the S&P 500 Index. The Lehman Brothers Aggregate Bond
Index is an unmanaged index made up of the government/corporate index, the
mortgage-backed securities index, and the asset-backed securities index. The
Lipper Balanced Fund Average is the average performance level of all
variable annuity balanced funds as reported by Lipper Analytical Services, an
independent organization that monitors the performance of variable annuity
funds and mutual funds.

The calculations for all indexes and averages are based on a full calendar
year in 1995, whereas the VA Diversified Assets Fund calculations are based
on a starting date of January 5, 1995 - the inception date of this Fund. This
comparison is for illustrative purposes only.

GENERAL DISCUSSION
By Portfolio Managers Harry Miller (Common Stock) and Paul Lundmark (Debt
Securities)

THE MARKET
Common Stocks - The Standard and Poor's 500 Index closed at 970.43 on
December 31, 1997, a 9% gain over 885.14 as of our last reporting on June 30,
1997. The Index was up more than 33% for the year. A great deal of this
change is attributed to lower interest rates and good earnings reports. Other
favorable factors were lower unemployment and very low inflation.

Debt Securities - Over the past six months, interest rates have fallen
significantly. Even in the face of economic growth, investors are optimistic
that inflation will remain tame and the Federal Reserve won't raise overnight
rates anytime soon.

In looking at the year as a whole, bonds performed very well. The Lehman
Brothers Aggregate Bond Index return for 1997 was 9.65% which is up
considerably compared to the Index's 7.48% average annualized return over the
past five years.


INVESTMENT PROGRAM:

Approximately 60% of the Fund's assets are invested in equity securities 
selected for toal return potential and approximately 40% are invested in debt 
securities of varying maturities.  On December 31, 1997, the portfolio mix was 
61.9% common stocks and 36.2% fixed-income securities.

PORTFOLIO STRATEGY

Common Stocks - Since our last Report of June 30, 1997 the stock market
dropped sharply, recovered and is now selling at a higher level than six
months ago. The total return for the stock portfolio was 27.07% for 1997.

New companies which were added to the equity portfolio in the last six months
include: Bell Atlantic (telephones) through merger with NYNEX, Meritor
Automotive (auto parts) through spin-off from Rockwell International, Fleet
Financial (banks), Intel (electronics - semiconductors), and PMI Group 
(finance - diversified).

Companies which were deleted include: James River and Weyerhaeuser (paper &
forest products) and NYNEX (telephones) through merger with Bell Atlantic.

The Fund's best performing stocks were Fleet Financial, PNC Bank, SouthTrust and
Bankers Trust (banks); and GTE Corp., Bell Atlantic and SBC Communications

Debt Securities - As of the end of the reporting period, the bond segment had
a weighted average maturity of 7.08 years and a modified duration of 5.12.
This represented very little change from the last reporting period.  We kept
these parameters steady because we are not relying on an interest rate
forecast.  No one has been successful in predicting

the course of interest rates over time. We believe instead, that our focus
should be on securities that have the potential to provide attractive levels of
income and total return. This philosophy has led us to reduce our exposure in
lower-rated corporates and mortgage pass-through securities that carry high
coupons. We have replaced those securities with instruments that are AAA rated
and not as interest-rate sensitive as the higher coupon pass-throughs.

The total return for the bond portfolio was 11.27% for 1997. The larger
percentage of corporates and mortgages in the portfolio versus treasuries
contributed to the Fund outperforming the Lehman Aggregate Bond Index. Positive
developments at HUBCO, WorldCom, and Tele-Communications, Inc. resulted in
additional price appreciation for the overall portfolio.

OUTLOOK

Common Stocks - Interest rates and inflation remain low, which is good for
the stock market; however, we are seeing some earnings disappointments.  The
Asian situation will be with us for some time which will effect our domestic
markets.  We remain optimistic with regard to the U.S. stock market but do
not expect the same returns in 1998 that we have experienced during the past
few years.

The portfolio is broadly diversified in 27 industries with 39 issues.  Common
stocks comprise 62% of the total net assets.  We remain overweighted in
automobiles, banks, telephones, healthcare - diversified, drugs, and medical
products & supplies.

Debt Securities - I wish I had a crystal ball that could foretell where interest
rates are headed. Since I don't, the best way I can provide value is by
continuing with the strategy of finding securities that provide attractive
yields and offer value in terms of risk and reward.

GENERAL DISCUSSION
by Portfolio Managers John K. Cabell and Eric M. Efron

THE MARKET

Since the USAA Life VA Aggressive Growth Fund began on May 5, 1997, U.S.
equity markets have gone through two distinct phases.  From May until
October, the market was in a positive phase, during which widely held
expectations for sustained low interest rates and healthy earnings growth
buoyed domestic stock prices.  Then, from October through December, the Asian
currency and economic crises reduced investors' confidence in both the
international and domestic markets.  This attitude was further fueled by
announcements of disappointing earnings from high-profile companies such as
Gillette and Coca Cola.  As a result, stock prices retraced a good part of
the gains they enjoyed from May through September.

With this type of market activity, it should come as no surprise that small
capitalization (cap) growth stocks, which account for the bulk of this Fund's
investments, continued to underperform most other equity classes, and the Fund's
performance reflects this. In the May through December period, the Fund
generated a total return of 18.3% versus 21.7% for the Russell 2000 
(Registration Mark) Index and 18.3% for the S&P 500/1/.

/1/  The S&P 500 Index is an unmanaged index representing the average
     performance of a group of 500 widely held, publicly traded stocks.

           AN OVERVIEW (Continued)                DECEMBER 31, 1997


THE PORTFOLIO STRATEGY

We continue to believe that sustained rapid earnings growth is the most
effective way to build value over the long term. We also believe that high
quality, smaller companies have the potential to capitalize quickly on emerging
trends in our economy and society, to grow faster, and therefore, to appreciate
more rapidly than larger ones. With this in mind, we continue to invest most of
the Fund's assets in small cap growth equities.

Nevertheless, we recognize that small cap stocks can be very volatile and that
despite their superior growth potential, small growth stocks can also
underperform larger stocks over extended periods of time. In order to mitigate
these problems, we have invested some of our funds in highly visible, well-known
large growth stocks such as Intel, Microsoft, Cisco Systems, Dell Computer, Home
Depot, Southwest Airlines, and Household International, just to name a few.
Although these are large companies, they are still innovative, rapidly growing,
and therefore, consistent with our investment style and spirit.

We cut back significantly on the number of equity holdings from 314 on June 30,
1997 to 209 on December 31, 1997. We feel that concentrating on fewer holdings
with larger positions will increase the impact each holding has on the portfolio
and will contribute to overall improved performance.

The Fund has invested heavily in technology, telecommunications services, and
energy sectors in recent months. Despite their potential volatility, technology
stocks are a core component to the portfolio and, on a long-term basis, well
worth the risks associated with them. Technology lies at the heart of many of
the changes that are transforming our world and is essential to enhancing
productivity and competitive positions. We have taken advantage of the weakness
of technology stocks, particularly small cap, in late 1997 to initiate new
positions and add to established ones at what we think will prove to be bargain
prices.

          AN OVERVIEW (Continued)                  DECEMBER 31, 1997


Earnings at telecommunications services companies are not particularly sensitive
to the economy. Furthermore, we have invested in companies whose stock has
limited overseas exposure, and therefore, should not subject investors to
worries about problems overseas. Also, the regulatory climate is extremely
favorable. Local monopolies are being dismantled around the world, giving rise
to the creation of smaller, entrepreneurial service providers in the local, long
distance, and wireless sectors. These companies are poised for rapid growth and
consolidation. Accordingly, we have invested in a large number of companies in
this area including: Teleport, LCI, Omnipoint, and Pacific Gateway Exchange.

In addition, the Fund has invested heavily in the oil & gas-drilling/equipment
sector. Companies such as Friede Goldman, Santa Fe International, and Falcon
Drilling provide technology and equipment that enhance productivity and reduce
costs in the energy exploration and services area. Energy-related stocks have
declined in recent months over concerns about falling oil and gas costs, and
represent compelling investment opportunities at current levels.

OUTLOOK

Equity markets are likely to remain volatile. On the positive side, interest
rates are low and there appears to be no compelling reason why they should move
up significantly. The outlook also appears favorable on the inflation front.
However, concerns about the economy may temper investor enthusiasm in the months
to come. Investors should keep in mind that returns, particularly in aggressive
growth funds such as this one, are not generated at a steady rate over time.
Rather they tend to come in dramatic bursts, often in compressed time periods
and often when we least expect it. Patience is advised. We believe that this
strategy will be rewarded amply over the long term.

GENERAL DISCUSSION

C. Sebastian

MARKET CONDITIONS

For the six months ending December 31, 1997 European markets have continued
to perform favorably while the performance of emerging markets has been
mixed.  Our underweighted position in Japan has proven to be a prudent
decision.

Europe - European markets provided favorable returns during the past six
months because of earnings growth, falling interest rates, and corporate
restructuring. Our holdings in Italy, Portugal, and the United Kingdom made
significant contributions to our European performance.  In fact, we increased
our exposure to the United Kingdom because of attractive valuations and a
stable, pro-business political environment.

INVESTMENT PROGRAM:

At least 80% of the Fund's assets will be invested in equity securities of 
foreign companies.

           AN OVERVIEW (Continued)                 DECEMBER 31, 1997


Emerging Markets - A series of currency devaluations in Asia have caused
turmoil and political disarray in many Asian countries.  This situation has
brought about a reduction in forecasted economic growth. We believe the
Brazilian economy will be affected by the Asian slowdown; however, Argentina,
Peru, and Mexico continue to show signs of recovering, driven by improving
domestic economies. In Mexico's case, stronger economic ties with the U.S.
are a driving force. Our expectations that political and economic reform
would gain momentum in Russia and Hungary proved correct as did our decision
to slightly increase our exposure in these countries.  Falling inflation and
interest rates in Israel have underpinned its market rally while the prospect
of economic reform has fueled Turkey's rise.

Japan - Asia's currency crisis, combined with problems within the banking
system, has begun to take its toll on the Japanese economy and stock market.
We believe that decisive action on restructuring Japan's tax and financial
systems is needed. We continue to hold export-related stocks while looking
for quality domestic-related companies. Our underweighted position in Japan
remains unchanged for the time being.

Other Markets - Our overweighted position in Canada reflects the
attractiveness of the economy as well as our favorable outlook for Canadian
energy stocks.  In Australia, we have reduced equities to be more in line

          AN OVERVIEW (Continued)                 DECEMBER 31, 1997
 
OUTLOOK

We will continue to favor European markets because of their economic and
political stability, favorable valuations, and more predictable earnings
growth. Divergence in emerging markets should continue as most Asian markets
remain weak while many Latin American, Eastern European, and other markets
are likely to recover sooner. We do not anticipate a marked improvement for
the Japanese economic picture and feel that it offers only selective
opportunities.


Foreign investing is subject to additional risks such as currency fluctations, 
market illiquidty, and political instability which are discussed in the 
prospectus.  Since return on any investment is generally commensurate with risk,
investors should be aware of the potential volatility associated with foreign 
markets.

                          INDPENDENT AUDITORS' REPORT

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES
USAA LIFE INVESTMENT TRUST

We have audited the accompanying statements of assets and liabilities and
portfolios of investments in securities of the USAA Life Variable Annuity
(VA) Money Market Fund, USAA Life VA Income Fund, USAA Life VA Growth and
Income Fund, USAA Life VA World Growth Fund, USAA Life VA Diversified Assets
Fund, USAA Life VA Aggressive Growth Fund, and USAA Life VA International
Fund, all funds of the USAA Life Investment Trust, as of December 31, 1997,
the statements of operations for the year then ended, and the statements of
changes in net assets for the years ended December 31, 1997 and 1996 and the
financial highlights for each of the years in the two-year period ended
December 31, 1997 and the period from January 5, 1995 (commencement of
operations) through December 31, 1995 for the Money Market Fund, Income Fund,
Growth and Income Fund, World Growth Fund and Diversified Assets Fund; and
the statements of operations, the statements of changes in net assets and the
financial highlights for the period from May 1, 1997 (commencement of
operations) through December 31, 1997 for the Aggressive Growth Fund and
International Fund. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 1997, by correspondence
with the custodian and brokers. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
each of the funds constituting the USAA Life Investment Trust as of December
31, 1997, the results of their operations for the year or period then ended,
the changes in their net assets for each of the years or periods in the
two-year period then ended, and the financial highlights for each of the
years or periods in the three-year period then ended as described in the
first paragraph, in conformity with generally accepted accounting principles.

GENERAL NOTES
Market values of securities are determined by procedures and practices
discussed in Note 1 to the Trust's financial statements.

The cost of securities for federal income tax purposes is approximately the
same as that reported in the financial statements.

The percentages shown represent the percentage of the investments to net
assets. Investments in foreign securities were 3.6% and 5.6% of net assets at
December 31, 1997, of the USAA Life VA Growth and Income Fund and the USAA
Life VA Aggressive Growth Fund, respectively.

ADS/ADR - American Depositary Shares/ Receipts are foreign shares held by a
U.S. bank which issues a receipt evidencing ownership.  Dividends are paid in
U.S. dollars.

GDS/GDR - Global Depositary Shares/Receipts are foreign shares held by a
non-U.S. bank which issues a receipt evidencing ownership.  Dividends are
paid in U.S. dollars.

SPECIFIC NOTES

general supervision of the Board of Trustees. At December 31, 1997, this

CATEGORIES AND 
DEFINITIONS

The securities in USAA Life VA Money Market Fund are divided into two
categories- fixed rate instruments and variable rate demand notes.

FIXED RATE INSTRUMENTS - consist of corporate and government notes and
commercial paper. The coupon rate is constant to maturity.

VARIABLE RATE DEMAND NOTES (VRDN) - provide the right, on any business day,
to sell the security at face value on either that day or in seven days.  The
interest rate is adjusted at the stipulated daily, weekly, or monthly
interval to a rate that reflects current market conditions.  The VRDN's
effective maturity is the date on which the underlying principal amount may
be recovered or the next rate adjustment date consistent with applicable
regulatory requirements.  Most VRDNs possess a credit enhancement.

CREDIT ENHANCEMENT (CRE) - adds the financial strength of the provider of the
enhancement to support the issuer's ability to repay the principal when due. The
enhancement may be provided by either a high quality bank, insurance company, or
other corporation, or a collateral trust. Typically, the rating agencies
evaluate the security based upon the credit standing of the credit enhancement,
rather than the credit standing of the issuer.

                         NOTES TO FINANCIAL STATEMENTS

                                                          DECEMBER 31, 1997  

1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USAA LIFE INVESTMENT TRUST (the Trust), registered under the Investment Company
Act of 1940, as amended, is a diversified, open-end management investment
company organized as a Delaware business trust consisting of seven separate
funds. The USAA Life VA Aggressive Growth and International Funds commenced
operations May 1, 1997 with an initial investment from USAA Life Insurance
Company (USAA Life). USAA Life is a wholly owned subsidiary of United Services
Automobile Association (USAA), a large, diversified financial services
institution.

The investment objectives of the Funds are as follows:

USAA LIFE VA MONEY MARKET FUND: Highest level of current income consistent with
preservation of capital and maintenance of liquidity.

USAA LIFE VA INCOME FUND:  Maximum current income without undue risk to
principal.

USAA LIFE VA GROWTH AND INCOME FUND: Capital growth and current income.

USAA LIFE VA WORLD GROWTH FUND: Long-term capital appreciation.

USAA LIFE VA DIVERSIFIED ASSETS FUND:  Long-term capital growth, consistent
with preservation of capital and balanced by current income.

USAA LIFE VA AGGRESSIVE GROWTH FUND: Appreciation of capital.

USAA LIFE VA INTERNATIONAL FUND: Primary objective is capital appreciation.
Current income is a secondary objective. 

Shares of the Funds currently are offered only to the Separate Account of USAA
Life Insurance Company (the Separate Account) to serve as the funding medium for
certain variable annuity contracts offered by USAA Life.

A. SECURITY VALUATION - The value of each security is determined (as of the
close of trading on the New York Stock Exchange on each business day the
Exchange is open) as set forth below:

1. Portfolio securities, except as otherwise noted, traded primarily on a
domestic securities exchange are valued at the last sales price on that
exchange. Portfolio securities traded primarily on foreign securities exchanges
are generally valued at the closing values of such securities on the exchange
where primarily traded. If no sale is reported, the average of the bid and asked
prices is generally used depending upon local custom or regulation.

2. Over-the-counter securities are priced at the last sales price or, if not
available, at the average of the bid and asked prices.

3. Securities purchased with maturities of 60 days or less and, pursuant to Rule
2a-7 of the Investment Company Act of 1940, as amended, all securities in the
USAA Life VA Money Market Fund, are stated at amortized cost which approximates
market value.

4. Other debt and government securities are valued each business day by a
pricing service (the Service) approved by the Funds' Board of Trustees. The
Service uses the mean between quoted bid and asked prices or the last sale price
to price securities when, in the Service's judgement, these prices are readily
available and are representative of the securities' market values. For many
securities, such prices are not readily available. The Service generally prices
these securities based on methods which include consideration of yields or
prices of securities of comparable quality, coupon, maturity and type,
indications as to values from dealers in securities, and general market
conditions.

5. Securities which cannot be valued by the methods set forth above, and all
other assets, are valued in good faith at fair value, using methods determined
by the investment advisor under the general supervision of the Board of
Trustees.

B. FEDERAL TAXES - The Funds' policy is to comply with the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of their income to their shareholders, the Separate
Account and USAA Life. Therefore, no federal income or excise tax provision is
required. As a result of certain permanent differences between book and tax
basis accounting, reclassifications have been made on the statement of assets
and liabilities of the USAA Life VA Aggressive Growth Fund at December 31, 1997
to decrease accumulated net investment loss and to decrease accumulated net
realized gain on investments by approximately $40,000.

C.  INVESTMENTS IN SECURITIES - Security transactions are accounted for on
the date the securities are purchased or sold (trade date).  Gain or loss
from sales of investment securities is computed on the identified cost basis.
Dividend income, less foreign taxes, if any, is recorded on the ex-dividend
date. If the ex-dividend date has passed, certain dividends from foreign
securities are recorded upon notification. Interest income is recorded on the
accrual basis. Discounts and premiums on short-term and long-term securities are
amortized over the life of the respective securities.

D.  FOREIGN CURRENCY TRANSLATIONS - The assets of the USAA Life VA Growth
and Income, World Growth, Aggressive Growth, and International Funds may be
invested in the securities of foreign issuers.  Since the accounting records
of the Funds are maintained in U.S. dollars, foreign currency amounts are
translated into U.S. dollars on the following basis:

B-62 ANNUAL REPORT 1997

                          USAA LIFE INVESTMENT TRUST
       
                         NOTES TO FINANCIAL STATEMENTS

                (Continued)                               DECEMBER 31, 1997  


1. Market value of securities, other assets, and liabilities at the mean between
the bid and asked translation rates of such currencies against U.S. dollars.

2. Purchases and sales of securities, income, and expenses at the rate of
exchange obtained from an independent pricing service on the respective dates of
such transactions.

Net realized and unrealized foreign currency gains/losses occurring during
the holding period of investments are a component of realized gain/loss on
investments and unrealized appreciation/depreciation on investments,
respectively.

Net realized foreign currency gains/losses arise from sales of foreign
currency, currency gains/losses realized between the trade and settlement dates
on security transactions, and the difference between amounts of dividends,
interest, and foreign withholding taxes recorded on the Fund's books and the
U.S. dollar equivalent of the amounts received. Net realized foreign currency
gains/losses have been reclassified from accumulated net realized gain/loss to
accumulated undistributed net investment income on the statement of assets and
liabilities as such amounts are treated as ordinary income/loss for tax
purposes. Net unrealized foreign currency exchange gains/losses arise from
changes in the value of assets and liabilities other than investments in
securities resulting from changes in the exchange rate.

E. USE OF ESTIMATES - The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that may affect the reported amounts in the financial
statements.

2) DISTRIBUTIONS
USAA LIFE VA MONEY MARKET FUND
Net investment income is accrued daily as dividends and distributed monthly
to its shareholder, the Separate Account.  All net investment income
available for distribution was distributed at December 31, 1997.
Distributions of realized gains from security transactions not offset by
capital losses are made annually or as otherwise required to avoid the
payment of federal taxes.

USAA LIFE VA INCOME, USAA LIFE VA GROWTH AND INCOME, USAA LIFE VA WORLD
GROWTH, USAA LIFE VA DIVERSIFIED ASSETS, USAA LIFE VA AGGRESSIVE GROWTH, AND
USAA LIFE VA INTERNATIONAL FUNDS

Distributions of net investment income and realized gains from security 
transactions not offset by capital losses are made to the shareholders annually 
or as otherwise required to avoid the payment of federal taxes.

3) INVESTMENT TRANSACTIONS
Cost of purchases and proceeds from sales/maturities of securities, excluding

4) FOREIGN CURRENCY CONTRACTS
A forward currency contract (currency contract) is a commitment to purchase or
sell a foreign currency at a specified date, at a negotiated price. The USAA
Life VA World Growth and International Funds currently enter into currency
contracts only in connection with the purchase or sale of a security denominated
in a foreign currency. These contracts allow the Funds to "lock in" the U.S.
dollar price of the security. Currency contracts are valued on a daily basis
using foreign currency exchange rates obtained from an independent pricing
service. Risks of entering into currency contracts include the potential
inability of the counterparty to meet the terms of the contract and the Funds
foregoing the opportunity for potential profit.
