     1. In  the  opinion  of  Management,  the  accompanying
        unaudited     consolidated    condensed    financial
        statements  contain all adjustments,  consisting  of
        normal  recurring items, necessary to present fairly
        the  financial  position, results of operations  and
        cash  flows  for  the  periods  shown.   It  is  the
        Company's  policy to end its first  three  quarterly
        accounting  periods  on  the  last  Friday  of  each
        quarter,   which   includes   thirteen   weeks    of
        operations.   The fourth quarter ends on  March  31.
        Except  as  noted  in the following  paragraph,  the
        financial  data  included  herein  was  compiled  in
        accordance with the same accounting policies applied
        to    the   Company's   audited   annual   financial
        statements, which should be read in conjunction with
        these statements.
     
        The  results of operations for the twenty-six  weeks
        ended   September  25,  1998,  are  not  necessarily
        indicative  of  the results to be expected  for  the
        full year.

     3. On  May  14, 1998, the Company acquired all  of  the
        outstanding shares of PRB Associates, Inc. (PRB),  a
        privately-held corporation with annual  revenues  of
        approximately  $30 million.  The purchase  price  of
        $20 million was financed through borrowings under  a
        revised  credit facility and notes.  The acquisition
        has  been  accounted for under the  purchase  method
        with   assets   acquired  and  liabilities   assumed
        recorded at their estimated fair values at the  date
        of  acquisition.  The purchase price  allocation  is
        based  upon preliminary information and as a result,
        management's  estimates may differ  from  the  final
        allocation. The purchase price as of May 1, 1998 was
        allocated  as follows: intangible assets  consisting
        of  $15,089,000  of  goodwill, $250,000  in  not  to
        compete  agreements  and   $139,700  of  total  debt
        costs.   The  remaining purchase price was  assigned
        primarily to  cash, receivables, property plant  and
        equipment  and  current and long  term  liabilities.
        Goodwill    will   be  amortized  over   25   years.
        Additionally,  in  connection  with  the   continued
        employment  of a key executive of PRB,  the  Company
        awarded 20,000 shares of restricted stock based upon
        a  quarterly vesting schedule commencing  August  1,
        1998, with the last vesting date occurring on May 1,
        2000.
     
        The combined pro forma results of operations for the
        twenty-six  weeks  ended  September  25,  1998   and
        September 26, 1997, had the acquisition occurred  at
        the beginning of each period, are as follows:

4. Effective  April  1,  1998, the Company adopted  Statement  of
   Financial    Accounting   Standards   No.   130,    "Reporting
   Comprehensive Income."  This statement requires that companies
   disclose  comprehensive  income, which  includes  net  income,
   foreign  currency  translation  adjustments,  minimum  pension
   liability  adjustments, and unrealized  gains  and  losses  on
   marketable   securities classified as available-for-sale.  For
   the  twenty-six weeks ended September 25, 1998  and  September
   26, 1997, there were no elements of comprehensive income other
   than net income.
   
5. During  the twenty-six  weeks ended September 25, 1998, 43,482
   common shares of the Company's stock were purchased and placed
   into Treasury stock.  These shares were acquired pursuant to a
   stock  repurchase  plan  approved by the  Company's  Board  of
   Directors.   Also during the twenty-six weeks,  70,578  common
   shares  were  issued from the Company's treasury shares.   The
   total number of treasury shares as of  September 25, 1998  was
   452,857.

6. During  the  twenty-six weeks ended September  25,  1998,  the
   Company  granted  106,528 options under its  Equity  Incentive
   Plans and 15,000 options under its Stock Option Plan for  Non-
   Employee  Directors.  Accordingly, options for 542,390  shares
   were  outstanding under the Equity Incentive Plans and 103,000
   shares  were outstanding under the Stock Option Plan  for  the
   Non-Employee  Directors; including 3,000  options  which  were
   granted  contingent upon approval by Shareholders at the  1999
   Annual Meeting of an increase in the plan reserve.  A total of
   308,459 shares were exercisable under these plans.

7. As   discussed  in  note  10  to  the  Company's  Consolidated
   Financial  Statements as of and for the year ended  March  31,
   1998, the Company holds 249,000 common shares of ARIA Wireless
   Systems,  Inc.  No value has been recorded for this investment
   in  the  Balance  Sheet.  On September 25,  1998,  the  common
   shares  of  ARIA were quoted on the OTC Bulletin  Board  at  a
   closing price of $0.406 per share.

8. The   Company  will  adopt  the  disclosure  requirements   of
   Statement  of Financial Accounting Standards (SFAS)  No.  131,
   "Disclosures  about  Segments of  an  Enterprise  and  Related
   Information," for the fiscal year ending March  31,  1999,  as
   required.   Adoption  of  SFAS No. 131  will  not  affect  the
   segments currently reported.

   The Company will adopt SFAS No. 133 "Accounting for Derivative
   Instruments  and Hedging Activities," for the  fiscal  quarter
   beginning  April  1,  2000,  as  required.   Because  of   the
   Company's  current  minimal  hedging  activity  and  lack   of
   derivative  instruments, the Company does not anticipate  that
   the adoption of SFAS No. 131 will have a significant effect on
   its earnings or financial position.

25,  1998,  and the related consolidated condensed statements  of
operations  for  the thirteen and twenty-six week  periods  ended
September  25,  1998  and  September 26,  1997,  and  changes  in
shareholders'  equity  and cash flows  for  the  twenty-six  week
periods  ended September 25, 1998 and September 26, 1997.   These
consolidated    condensed   financial    statements    are    the
responsibility of the Company's management.

We  conducted our review in accordance with standards established
by  the  American Institute of Certified Public  Accountants.   A
review  of interim financial information consists principally  of
applying  analytical  procedures to  financial  data  and  making
inquiries  of  persons responsible for financial  and  accounting
matters.   It  is  substantially less  in  scope  than  an  audit
conducted   in   accordance  with  generally  accepted   auditing
standards, the objective of which is the expression of an opinion
regarding   the   financial  statements   taken   as   a   whole.
Accordingly, we do not express such an opinion.

Based   on   our  review,  we  are  not  aware  of  any  material
modifications  that should be made to the consolidated  condensed
financial  statements  referred  to  above  for  them  to  be  in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted
auditing  standards, the consolidated balance  sheet  of  Comptek
Research,  Inc. and subsidiaries as of March 31,  1998,  and  the
related   consolidated  statement  of  operations,  shareholders'
equity,  and  cash flows for each of the years in the  three-year
period then ended (not presented herein); and in our report dated
May  14,  1998,  we  expressed an unqualified  opinion  on  those
consolidated   financial  statements.   In   our   opinion,   the
information set forth in the accompanying consolidated  financial
statements.   In our opinion, the information set  forth  in  the
accompanying consolidated condensed balance sheet as of March 31,
1998,  is fairly presented, in all material respects, in relation
to the consolidated balance sheet from which it has been derived.

              Management's Discussion and Analysis

GENERAL

The Company provides defense-related systems, software and
proprietary products intended for the global military electronics
market.  The Company currently reports its operating activities
into two defense-related segments:  Engineering and Technical
Services ("Services") segment and the Defense Systems ("Systems")
segment.  On May 14, 1998, the Company completed its acquisition
of PRB Associates, Inc. ("PRB").  The second quarter ended
September 25, 1998, includes a full three months of PRB's
operations reported in the Systems segment.

In October 1998, the Company signed a letter of intent to acquire
the business operations, assets and related liabilities of
Amherst Systems, Inc., a supplier of products for simulation and
evaluation of the electronic combat environment.  This
transaction is subject to the completion of due diligence, the
signing of a definitive purchase agreement, the obtaining of
financing and customary regulatory approvals.

RESULTS OF OPERATIONS

NET SALES.  Net sales for the six months ended September 25,
1998, were $43.7 million, an increase of 23% from the prior
year's net sales of $35.6 million. For Systems, net sales
advanced to $25.5 million for the first six months compared with
$11.9 million for the same period in the prior year.  This
increase in sales was the result of the acquisition of PRB in May
1998.  PRB, a developer of military mission planning systems and
mission support and analysis equipment, operates primarily under
the Systems segment.  Net sales for the Systems segment grew to
58% of the Company's total net sales for the six months ended
September 25, 1998, compared with 33% in the prior year.  During
the first half of fiscal 1998, the Company experienced a
reduction in the lower-margin subcontractor work on the
Electronic Combat Mission Support (AECMS@) contract with the U.S.
Navy.  The U.S. Navy continues to contract a large portion of
subcontractor work directly, as opposed to this activity passing
through the Company's U.S. Navy contract.  As a result, net sales
for Services decreased for the first six months by 23% when
compared with the prior year.  The Company anticipates that the
U.S. Navy's current practice will continue going forward and
will, as a result, yield similar comparisons to prior quarterly
periods.  During the fiscal 1999 second quarter, U.S. Navy
awarded the Company a follow-on ECMS contract for an additional
two years with a potential value of up to $28.7 million.

Backlog as of September 26, 1998, remained relatively unchanged
at $155.2 million compared with $155.6 million at June 26, 1998.
Since March 31, 1998, backlog has increased 50% primarily due to
the addition of PRB's backlog at the time of the acquisition and
the July 1998 award of contracts valued at over $18.5 million for
work on the upgrade of the electronic warfare system or the EA-6B
Prowler Aircraft.

GROSS MARGIN.  Gross Margin for the first six months was 25%
compared with 20% in the prior year.  As in the first quarter of
fiscal 1999, the Company during the second quarter continued to
experience increases in the Systems segment net sales which
typically produce higher-than-average gross margins for the
Company.  Additionally, the reduction of subcontractor sales in
the Services segment which typically produce lower-than-average
gross margins resulted in an overall gross margin percentage
improvement.

SELLING, GENERAL AND ADMINISTRATIVE ("SG&A").  As a percentage of
net sales, SG&A expenses were 14% or $6.3 million for the first
six months.  In the prior year, SG&A, as a percentage of net
sales, was 12% or $4.3 million.  Consistent with the first
quarter, the acquisition of PRB has resulted in the overall
increase in expenditures for SG&A.  While the increases in the
Systems segment business have produced higher gross margins,
Systems requires a higher level of expenditures in marketing and
bidding efforts to win new contracts.

RESEARCH AND DEVELOPMENT (AR&D@).  R&D efforts for the first six
months resulted in an expense of $1.3 million compared with
$400,000 in the prior year.  R&D efforts are concentrated
primarily in the Company's System segment.   The operations of
PRB, since May 1, 1998, added approximately $850,000 in R&D

<PAGE 10>

expenditures.  The remaining  R&D expenditures were the result of
ongoing development activity with the Company's simulation
products.  The Company anticipates that the expenditures for R&D
will continue at the current rate for the remainder of the fiscal
year.  The Company currently expects that as the Systems business
grows, the level of R&D expenditures in total dollars will
increase due to the developmental nature of the Systems business.
In the past, the majority of the Company operations and net sales
were Services based, which typically required relatively low
amounts of R&D investments.  The Company anticipates continued
growth in the Systems business through both internal growth and
acquisition.  As a result, R&D expenditures in total dollars, and
as a percentage of sales, is likely to increase.

NET INTEREST EXPENSE.  Net interest expense for the first six
months increased to approximately $646,000 compared with $235,000
in the prior year.  This increase is attributable to the
financing costs relating to the acquisition of PRB.

INCOME TAXES.  The Company reported an overall effective tax rate
(Federal and State) of approximately 40%, compared with 39%
booked in the prior year.  This slight increase is the result of
the non-deductibility of the goodwill created as a result of the
PRB acquisition.

NET INCOME.  Net income increased to $1.4 million, or $.28 per
diluted share, for the six months from $1.2 million, or $.22 per
diluted share, in the prior year.  During the six month period,
net income increased by $123,000, or by 19.2%, as compared with
the prior corresponding period.  For the second quarter, net
income increased to $765,000, or $.15 per diluted share, in the
current year from $642,000, or $.12 per diluted share, in the
prior year.  During the second quarter period, net income
increased by $241,000, or by 20%, as compared to the prior
corresponding period.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities for the first six
months was $895,000 compared with $2,737,000 a year ago.
Accounts payable required cash of $3,240,000, while net earnings
of $1,448,000 and the collection of accounts receivable generated
cash.  Accounts payable in the first half of the fiscal year
required a relatively significant amount of cash primarily due to
the timing of payments to subcontractors and the related
collection on accounts from customers at year-end and the prior
year's quarter-end. In the first half of the prior year, accounts
payable required substantially less cash of $744,000.   Positive
cash flow thus far for fiscal 1999 has been used to purchase
capital equipment and complete software development.  Cash
generated from the sale of treasury shares to the Company's
employees through the Employee Stock Purchase Plan was used to re-
purchase the Company's common shares for the treasury.

The Company's acquisition of all of the outstanding shares of PRB
for a purchase price of $20 million, was financed with borrowings
under a revised credit facility and notes. Total payments for the
acquisition net of cash received was $17.9 million.  The
Company's total long-term debt was reduced by approximately $1.4
million since June 26, 1998.

The Company's total debt-to-equity ratio decreased to 2.69 to 1
at September 25, 1998, from 3.07 to 1 at June 26, 1998.  The
decrease is the result of the repayment of long-term debt coupled
with increases in the Company's shareholders equity.

The Company anticipates, exclusive of the financing required for
the pending Amherst Systems acquisition, that cash flow from
operations and available funds from its credit facilities will be
sufficient to satisfy operational requirements and capital
expenditure needs of the Company for the remainder of the fiscal
year.

YEAR 2000

The Company continues to address the issue of its readiness in
light of government and industry reports of potentially serious
and widespread problems resulting from computer programs failing
to correctly recognize the Year 2000, a situation commonly
referred to as the "Year 2000 Issue" or "Year 2000 Problem."  The
Company has completed its assessment of its internal systems,
including its information technology systems and non-information
technology systems, for potential impact of Year 2000 Issues.
The Company has also

<PAGE 11>

received communications from all of its major vendors and
suppliers as to their respective states of readiness and plans
for compliance.

In this regard, the Company is currently in the final stages of
converting its primary accounting and management information
system.  The decision to convert was based upon information
processing and management  reporting enhancements available under
the new system.  While such conversion was not initiated or
accelerated due to the prospect of the Year 2000 Problem, the new
system has been represented to the Company as Year 2000 compliant
and provides the ancillary benefit of addressing the Year 2000
Issue.  Over the next six to nine months the Company will be
conducting testing to verify compliance.  The majority of the
cost for the new system (approximately $205,000) was included in
the Company's capital expenditures in the prior fiscal year.
Remaining expenditures (estimated at $100,000) are included in
the Company's anticipated capital requirements for the current
fiscal year.  Deficiencies in non-information technology systems'
recognition of the Year 2000 which were identified as a result of
the Company's internal assessment have been corrected.  The cost
of correction was not material.

Ancillary management information systems used by the Company and
its subsidiaries have also been evaluated.  Specific upgrades to
achieve Year 2000 compliance are covered under existing
maintenance agreements or will be purchased for installation by
March 31, 1999.  The Company has also purchased diagnostic
software for testing all of its personal computer and
workstations and expects to complete testing within the next six
months.  The upgrade and testing of the payroll systems is
scheduled to be completed by July 31, 1999.  Other than the
capital expenditures noted in the preceding paragraph, the
Company has spent less than $10,000 on Year 2000 compliance
upgrades and currently expects total expenditures in the current
fiscal year to be less than $100,000.

While the Company continues to evaluate the compliance activities
of its vendors and suppliers, the Company is satisfied with the
responses received to date and does not anticipate any material
adverse impact on the Company's financial condition as it relates
to vendors' and suppliers' Year 2000 compliance.  The Company
will, to the extent feasible, be testing such products for
compliance, but can offer no assurances that its vendors and
suppliers will in fact be Year 2000 compliant.

As discussed in previous reports by the Company, including its
report on Form 10-K for the fiscal year ended March 31, 1998, the
United States Department of Defense and its departments and
agencies are the Company's largest customer group, representing
87% of the Company's 1998 net sales.  The Company believes that
the United States Government, including the Department of
Defense, is undertaking substantial efforts to address the Year
2000 Problem.  The Company, however, can offer no assurances as
to the Department of Defense's readiness and the potential impact
of the Department of Defense's non-readiness is unknown at this
time.  A failure by the Department of Defense to adequately
address the Year 2000 Problem could, among other things, result
in payment delays and contract administration delays which may
result in a need for increased borrowing and interest expense to
satisfy operational and capital expenditure needs of the Company.

Based on currently available information, the Company believes
that the most reasonably likely worst case  Year 2000 scenario
revolves around two factors:  (1) a failure or substantial
curtailment of basic power and communication services and (2)
payment and contract administration delays.  The Company is in
the process of evaluating contingency plans.  In many instances,
the establishment of a contingency plan related to basic power
and communications may not be possible or may be cost
prohibitive.  In order to address potential payment and contract
delays, the Company's current credit facility includes a $12
million line of credit for working capital.  Also, consistent
with the Company's overall cash management practices, a close
liaison is maintained with the Defense Contract Management Agency
to address potential payment and contract administration issues.

The software programs written by the Company's personnel and
currently in use by customers are believed to be Year 2000
compliant, but inasmuch as such programs are used in conjunction
with operating and other systems furnished by other suppliers,
the overall compliance of such systems is dependent upon third
parties.  The Company expects to continue to evaluate the
compliance activities of its contract vendors and suppliers, but
is satisfied with the responses received to date.  The Company
has evaluated and will continue to consider its, and its
subcontractors, warranty obligations relative to the Year 2000
Problem.  The Company has not

<PAGE 12>

received any warranty claims relating to the Year 2000 Problem
and does not currently anticipate any such claims of a material
nature.

While the Company does not currently anticipate a material
adverse impact on the Company's financial condition or results of
operations, the Company can offer no assurances that the Year
2000 Problem will not adversely impact on the Company.
Accordingly, the Company expects on an on-going basis to continue
to evaluate the Year 2000 Problem and its potential impact on the
Company and its industry group.

FORWARD LOOKING STATEMENTS

This Management's Discussion and Analysis contains forward-
looking statements about the Company's current expectations based
on current business conditions.  Forward-looking statements are
subject to risks and uncertainties that could cause actual
results to differ materially.  These risks and uncertainties
include the Company's dependence on continued funding of U.S.
Department of Defense programs.  Some additional risks and
uncertainties, among others, that also need to be considered are:
the likelihood that actual future revenues that are realized may
differ from those inferred from existing total backlog; the
ability to transition and integrate PRB, as well as complete the
proposed acquisition of the business operations of Amherst
Systems, Inc.; the ability to expand sales in international
markets; the ability to complete future acquisitions without
adversely affecting the Company's financial condition; and the
potential impact of the Year 2000 Problem.  Other risks and
uncertainties are described in the Company's Form 10-K Annual
Report for the fiscal year ended March 31, 1998.
