         Notes to Consolidated Condensed Financial Statements

                              (Unaudited)


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.   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 thirty-nine weeks ended December
   27,  1996,  are  not necessarily indicative of the  results  to  be
   expected for the full year.

2. During  the  first  quarter  of fiscal 1997,  the  Company  adopted
   Statement  of  Financial  Accounting  Standards  (SFAS)   No.   121
   "Accounting for the Impairment of Long-Lived Assets and  for  Long-
   Lived  Assets  to be Disposed of" and SFAS No. 123 "Accounting  for
   Stock-Based Compensation".

   The  Company's  previous policy on impairment  was  not  materially
   different than that prescribed by SFAS 121.  The adoption  of  SFAS
   121 on April 1, 1996, therefore, did not require any impairment  to
   be  recognized  during  the thirty-nine weeks  ended  December  27,
   1996.

   As  permitted by SFAS 123, the Company will continue to  apply  its
   current   accounting  policy  under  Accounting  Principles   Board
   Opinion  No.  25,  with respect to stock-based  compensation.   The
   adoption of SFAS 123 on April 1, 1996, therefore, had no effect  on
   the  Company's  consolidated  financial  position  or  results   of
   operations for the thirty-nine weeks ended December 27, 1996.

3. Receivables  include  costs and estimated  earnings  in  excess  of
   billings   on  uncompleted  contracts  which  primarily   represent
   revenues  recognized on contracts, including retainage,  for  which
   billings  could not be presented under the terms of  the  contracts
   at the balance sheet dates.

6. During  the  second quarter, the Company issued 202,814  "repriced"
   options with exercise prices equal to the fair market value on  the
   date  of repricing, or $5.625.  These "repriced" options were given
   in  exchange  for  the surrender of an equal number  of  previously
   issued  options  having  exercise prices ranging  from  $13.125  to
   $17.75.

   During  the thirty-nine weeks ended December 27, 1996, the  Company
   issued  100,000 options under its Equity Incentive Plan and  15,000
   options  under  its  Stock Option Plan for Non-Employee  Directors.
   An  aggregate  of  148,000  options  expired  during  such  period.
   Accordingly, options for 374,659 shares were outstanding under  the
   Equity Incentive Plan and 63,000 shares were outstanding under  the
   Stock  Option  Plan  for the Non-Employee Directors.   A  total  of
   119,845 shares were exercisable under both plans.

                  Independent Auditors' Review Report



The Board of Directors and Shareholders
Comptek Research, Inc.:


We  have  reviewed the consolidated condensed balance sheet of Comptek
Research,  Inc.  and subsidiaries as of December  27,  1996,  and  the
related consolidated condensed statements of operations, shareholders'
equity, and cash flows for the thirty-nine week periods ended December
27,   1996  and  December  29,  1995.   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  obtaining  an
understanding  of the system for the preparation of interim  financial
information, applying analytical review procedures to financial  data,
and   making  inquiries  of  persons  responsible  for  financial  and
accounting matters.  It is substantially less in scope than  an  audit
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, 1996, and the  related
consolidated statements 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, 1996, we expressed
an unqualified opinion on those consolidated financial statements.  In
our   opinion,   the   information  set  forth  in  the   accompanying
consolidated condensed balance sheet as of March 31, 1996,  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

Financial Condition

The Company's operations provided positive cash flow of $3,356,000 for
the nine months ended, December 27, 1996, compared with $389,000 for
the same period last year.  This substantial improvement in net cash
provided by operating activities was primarily driven by increased
sales and net earnings.  Cash flow from operations was used to reduce
long-term debt and acquire capital equipment in the amount of
$2,789,000 and $474,000 respectively.  The Company also expended
during the first nine months $313,000 to repurchase 57,500 common
shares for the treasury pursuant to a stock buy back plan authorized
by the Board of Directors.

The Company  anticipates that cash flow from operations and available
funds from  its credit facilities will be sufficient to satisfy
operational and capital expenditure needs of the Company for the
remainder of the fiscal year.

Results of Operations

Net sales for the third quarter increased by 34% to $18,986,000 when
compared with the third quarter last year.  Net sales for the nine
months ended, December 27, 1996, increased 42% to $55,899,000.  This
sales growth is attributable to a combination of increases in volume
and the acquisition of Advanced Systems Development, Inc. (ASDI).
Increased contract revenues, including most notably the Company's U.S.
Navy contract for Electronic Combat Mission Support (ECMS), represents
approximately half of the current year sales increase.  The acquired
operation of ASDI accounts for the remainder of increased sales.

The Company's backlog on December 27, 1996, was $106.4 million an
increase of  72% since, March 31, 1996.  Similar to the sales increase
discussed above, the ECMS contract has been a major contributor to the
upswing in backlog during the current fiscal year.

Changes in gross margin for the third quarter and first nine-months of
fiscal 1997 relate to the mix of contract activities.  Gross margin
percentage for the third quarter was 16.7% a slight decrease when
compared with 16.9% for the third quarter last year.  Gross margin,
for the nine months of fiscal 1997 decreased to 16.8% from 17.1% in
the prior year.    Current year sales level on the ECMS contract when
compared with last year has reduced the overall margin.  This cost-
plus technical service contract produces lower than the Company's
average gross margin.  The current year sale of higher margin products
and the acquired operations of ASDI has minimized the impact of the
change in the year-to-date sales mix on the Company's gross margin.
Additionally,  higher margins were realized in the prior year due to
the completion of work earlier than anticipated on a higher margin
defense contract.

During the third quarter of fiscal 1997, the Company elected to
increase marketing and proposal efforts resulting in an increase in
third quarter SG&A expenditures of $118,000 when compared with the
second quarter of fiscal 1997.  SG&A expenditures for the first nine
months of fiscal 1997 increased by $638,000 when compared with fiscal
1996 primarily due to the acquired ASDI operations.   As a percentage
of sales, however,  year-to-date SG&A decreased to 10.5% of sales from
13.2% last year due to the substantial increase in sales base.

Research and Development (R&D) expenditures decreased by 54% and 37%
the for the third quarter and nine months of fiscal 1997 respectively,
when compared with fiscal 1996.  During prior year, the Company
concentrated on the development of new proprietary military products
and elected to participate in a U.S. government R&D project. During
fiscal 1997 the Company has concentrated on the technical enhancement
of current proprietary products.   Additionally, fiscal 1996 R&D
expenditures were higher due to the Commercial Segments operations,
which were included with the Company's operating results during the
first two months of fiscal 1996.

<PAGE 10>

Net interest expense increased by $103,000 for the third quarter and
$317,000 for the nine months ended December 27, 1996, when compared
with the prior year.  This increase is primarily attributable to long-
term debt incurred as a part of the acquisition of ASDI.  Net interest
expense has decreased slightly when compared with the first two fiscal
quarters, as a result of the repayment of the Company's long-term
debt.

The Company continues to record income taxes (Federal and state) at
the rate of 40%.   The Company's cash payments for taxes in fiscal
1997 are being reduced due to its available net operating loss (NOL)
carry forward.  The statement of operations' benefit of the loss
carryforward was recorded by the Company in the period when these
losses were generated.

During fiscal 1996 the Company recorded income of $477,000 as a result
of a settlement of litigation between the Company and M-Wave, Inc.,
and its wholly-owned subsidiary Poly Circuits, Inc.  This settlement
included $300,000 in cash and 20,000 shares of M-Wave common stock.

In the third quarter of fiscal 1996, the Company's investment in ARIA
Wireless Systems, Inc., (ARIA), was written down to zero.  The Company
recorded a loss from this investment of $7,502,000 for the third
quarter, and $8,615,000 for the nine-month period, ended December 29,
1995.  As a result, this investment has at this time no further
negative financial impact on the Company's financial statements.  On
April 30, 1996, ARIA filed a voluntary petition in the United States
Bankruptcy Court under Chapter 11 and subsequently has secured
approximately $3 million of debt-in-possession financing to facilitate
a reorganization.  On December 20, 1996 a proposed plan of
reorganization was submitted by ARIA and is currently under review by
the Court and creditors.  The Company continues to closely monitor
these proceedings in order to maximize the Company's investment
position.

Recent Accounting Pronouncements

The Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long -Lived Assets to be Disposed of" , and SFAS No. 123, "Accounting
for Stock-Based Compensation" on April 1, 1996.  As permitted by SFAS
123, the Company will continue to apply its current accounting policy
under Accounting Principles Board Opinion No. 25 and will include the
necessary disclosures in the 1997 annual financial statements.
