                                    FORM 10-Q

                     For the Quarter Ended September 30, 1994

           NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

 1.  In the opinion of management, the accompanying unaudited consolidated
     condensed financial statements reflect all adjustments (consisting of
     normal recurring accruals) necessary for a fair statement of the results
     for the interim periods.  The results of operations for the nine months
     ended September 30, 1994, are not necessarily indicative of the results
     to be expected for the full year.  The Corporation has continued to
     follow the accounting policies as stated in Note A to the financial
     statements included in its 1993 Annual Report.

 2.  Earnings for 1993 have been restated from the amounts originally
     reported to reflect the Corporation's adoption in 1993 of Statement of
     Financial Accounting Standards No. 112, "Employers Accounting for
     Post-employment Benefits".  The after-tax charge for the change in
     accounting for post-employment benefits was $17.4 million or 18 cents
     per common share.  The loss per common share from the changes in
     accounting for post-retirement benefits and post-employment benefits
     was $4.53 in the first quarter of 1993 and $4.51 for the full year.

 3.  In August 1994, Martin Marietta Corporation and Lockheed Corporation
     announced that their respective Board of Directors had unanimously
     approved a definitive agreement to merge the two corporations through
     an exchange of common stock (the "Combination").  The Combination,
     which is a "merger of equals" and does not involve the sale of either
     corporation, is subject to regulatory and stockholder approvals and
     is expected to close in the first quarter of 1995.  The Combination
     is expected to qualify as a pooling of interests for accounting and
     financial reporting purposes.  Under this accounting method, the assets
     and liabilities of Lockheed and Martin Marietta will be carried forward
     to the new corporation, Lockheed Martin Corporation, at their historical
     recorded bases.  Results of operations of Lockheed Martin will include
     the results of both Lockheed and Martin Marietta for the entire fiscal
     year in which the Combination occurs.  When consummated, the reported
     balance sheet amounts and results of operations of the separate
     corporations for prior periods will be combined, reclassified and
     conformed, as appropriate, to reflect the combined balance sheets and
     statements of results of operations for Lockheed Martin Corporation.

     On May 1, 1994, the Corporation completed its acquisition of the Space
     Systems division of General Dynamics. This transaction has been accounted
     for under the purchase method of accounting, wherein cost in excess of
     net assets acquired of approximately $213 million was recognized by the
     Corporation.  The cost in excess of net assets acquired is being
     amortized over a twenty-year period.

                    For the Quarter Ended September 30, 1994

         NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (Continued)

     At September 30, 1994, Space Systems division had
     customer deposits of approximately $1.3 billion which
     primarily represent advance payments from its Atlas
     program customers. In the Corporation's consolidated
     balance sheet, customer deposits of $315 million and $388
     million are classified as other current liabilities and
     other noncurrent liabilities, respectively.  Costs on
     contracts and programs in progress (See Note 6) are net
     of related customer deposits of $575 million.  Operating
     results of the Space Systems division have been included
     with those of the Corporation from the closing date.

     On November 22, 1992, Martin Marietta Corporation entered
     into a Transaction Agreement with General Electric
     Company (GE) to combine the aerospace and certain
     other businesses of GE (collectively, the "GE Aerospace
     businesses") with the businesses of Martin Marietta
     Corporation in the form of affiliated corporations.
     The transaction (the "GE Transaction"), was consummated
     on April 2, 1993, and GE Aerospace operations have been
     included in the consolidated financial statements since
     that date (See Note 16).

4.   Martin Marietta Corporation has adopted a Stockholder
     Rights Plan pursuant to which the Corporation distributed
     one Common Stock Purchase Right with respect to
     each share of its Common Stock outstanding as of the
     close of business on September 9, 1994, and rights attach
     to each additional such share issued thereafter until the
     earlier of the Distribution Date under the Rights
     Agreement or the date on which the Rights expire or are
     redeemed.  The Rights will expire immediately prior to
     consummation of the transactions contemplated by the
     above-mentioned agreement with Lockheed (See Note 3), or,
     if the transactions are not consummated, then on
     September 9, 2004, unless extended by the Corporation.
     The Rights are not exercisable except upon the occurrence
     of certain events described in the Rights Agreement.
     When exercisable, each Right will entitle the
     holder to purchase one share of Common Stock (or other
     shares, securities or property, as the case may be, of
     equivalent value) at an exercise price of $190.00
     per share.  The Rights will be redeemable at $0.01 per
     Right.

5.   In February 1994, Martin Marietta Materials, Inc., sold
     through an initial public offering, approximately 8.8
     million shares of its common stock.  After the public
     sale, the Corporation owns approximately 81% of the
     outstanding stock of the company.  A portion of the
     proceeds from the offering was used to defease
     in-substance certain long-term debt of Martin Marietta
     Materials (See Note 7).  The Corporation, through its
     subsidiary Martin Marietta Technologies, Inc., recognized
     an after-tax gain of $70.2 million, or 56 cents per share
     fully diluted, from Materials' initial public offering,
     net of the after-tax loss on the debt defeasance of $4.7
     million.

7.   In February 1994, Martin Marietta Materials Inc., a
     majority-owned subsidiary of Martin Marietta Technologies
     Inc., defeased in-substance the aggregate principal
     amount of $125 million of 9.5% Notes due in 1995.  These
     Notes were classified as long-term debt at December 31,
     1993.

     Martin Marietta Corporation has guaranteed the
     payment of certain debt obligations of Martin Marietta
     Technologies, Inc. The total of such guarantees,
     including the 9.5% Notes which were defeased
     in-substance, was $1.1 billion at September 30, 1994.
     Exposure to credit risk in the event of non-payment by
     the obligor is represented by the contractual amount of
     the relative instruments.  No loss is anticipated under
     these guarantees.  As of September 30, 1994, there were
     no restrictions on dividends or other distributions
     between Martin Marietta Technologies, Inc. and the
     Corporation.

     As of September 30, 1994, the Corporation has issued
     letters of credit totaling $259 million relating to
     certain long-term contracts and other contractual
     obligations.

     The Corporation's total interest payments were
     approximately $80 million in 1994 and $45 million in 1993
     for the nine months ended September 30.

 8.  Certain financing agreements of Martin Marietta
     Corporation and its subsidiaries contain restrictive
     covenants, including limitations on encumbrances and on
     sale and lease-back transactions.  Under an $800-million
     Revolving Credit Agreement, the Corporation is also
     subject to limitations on its financial leverage and a
     minimum fixed charge coverage ratio as defined by the
     agreement.  At September 30, 1994, there were no amounts
     outstanding under the credit facility.

13.  The Corporation's effective income tax rate for the first nine
     months was 40.7% in 1994 and 37.6% in 1993.  The effective rates
     in both years are higher than the statutory corporate federal income tax
     rate principally due to differences between book and tax accounting
     arising from the amortization of goodwill (cost in excess of net assets
     acquired) associated with the GE Transaction and state income taxes.

     Income tax payments were approximately $52 million in 1994 and $183
     million in 1993 for the nine months ended September 30.

14.  The ratio of earnings to fixed charges for the nine months ended
     September 30, 1994, was 8.83.  See Exhibit 12, Computation of Ratio of
     Earnings to Fixed Charges, on page 24.

15.  In the opinion of management (which opinion is based in part upon
     consideration of the opinion of counsel) and in the opinion of
     counsel, the probability is remote that the outcome of litigation and
     other proceedings, including those pertaining to environmental matters,
     relating to Martin Marietta, will have a material adverse effect on the
     results of the Corporation's operations or its financial position.

                                   (Continued)

16.  The following unaudited pro forma combined summary
     information presents the historical results of operations
     of the Corporation and the General Dynamics Space Systems
     division for the three and nine month periods ended
     September 30, 1994 and 1993 with pro forma adjustments as
     if the Space Systems division had been acquired as of the
     beginning of the periods presented. In addition, the
     historical results of operations of the GE Aerospace
     Businesses are included for the nine-month period ended
     September 30, 1993, with pro forma adjustments as if the
     GE Transaction had been consummated as of the beginning
     of the period.  The pro forma information is based upon
     certain estimates and assumptions that management of the
     Corporation believes are reasonable in the circumstances.
     The unaudited pro forma information is not necessarily
     indicative of what the results of operations actually
     would have been if the Space Systems and GE transactions
     had occurred on the dates indicated.  Moreover, they are
     not necessarily indicative of future results of
     operations.

      MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION AND OPERATING RESULTS
         Third Quarter and Nine Months Ended September 30, 1994 and 1993

Martin Marietta continued in excellent overall financial
condition during the third quarter of 1994.  The Corporation
maintains adequate capital resources to operate, compete and
grow in an increasingly challenging and competitive
marketplace.  Net earnings for the third quarter of 1994 were
$148.8 million, or $1.18 per share fully diluted, up 14% over
third quarter 1993 earnings of $131.1 million, or $1.04 per
share. Backlog of undelivered orders at September 30, 1994
was at $16.9 billion compared with $16.7 billion reported at
year-end 1993. The Corporation's ratio of debt-to-capitalization
at September 30, 1994 was 34%, down from 39% reported at December
31, 1993.

In August 1994, Martin Marietta Corporation and Lockheed
Corporation announced that their respective Board of Directors
had unanimously approved a definitive agreement to merge the
two corporations through an exchange of common stock (the
"Combination").  The Combination, which is a "merger of
equals" and does not involve the sale of either corporation,
is subject to regulatory and stockholder approvals and is
expected to close in the first quarter of 1995.  The
Combination is expected to qualify as a pooling of interests
for accounting and financial reporting purposes.  Under this
accounting method, the assets and liabilities of Lockheed and
Martin Marietta will be carried forward to the new
corporation, Lockheed Martin Corporation, at their historical
recorded bases.  Results of operations of Lockheed Martin will
include the results of both Lockheed and Martin Marietta for
the entire fiscal year in which the Combination occurs.  When
consummated, the reported balance sheet amounts and results of
operations of the separate corporations for prior periods will
be combined, reclassified and conformed, as appropriate, to
reflect the combined balance sheets and statements of results
of operations for Lockheed Martin Corporation.

Martin Marietta Corporation has adopted a Stockholder Rights
Plan pursuant to which the Corporation distributed one Common
Stock Purchase Right with respect to each share of its Common
Stock outstanding as of the close of business on September 9,
1994, and rights attach to each additional such share issued
thereafter until the earlier of the Distribution Date under
the Rights Agreement or the date on which the Rights expire or
are redeemed.  The Rights will expire immediately prior to
consummation of the transactions contemplated by the
above-mentioned agreement with Lockheed (See Note 3), or, if
the transactions are not consummated, then on September 9,
2004, unless extended by the Corporation.  The Rights are not
exercisable except upon the occurrence of certain events
described in the Rights Agreement.  When exercisable, each
Right will entitle the holder to purchase one share of Common
Stock (or other shares, securities or property, as the case
may be, of equivalent value) at an exercise price of $190.00
per share.  The Rights will be redeemable at $0.01 per Right.
Rights will be redeemable at $0.01 per Right.

      MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION AND OPERATING RESULTS
                                   (Continued)
         Third Quarter and Nine Months Ended September 30, 1994 and 1993

During the second quarter of 1994, the Corporation completed
its acquisition of the General Dynamics Space Systems division
for approximately $160 million in cash. This transaction has
been accounted for under the purchase method of accounting,
wherein cost in excess of net assets acquired of approximately
$213 million was recognized by the Corporation.  The cost in
excess of net assets acquired is being amortized over a
twenty-year period.  Operating results of the Space Systems
division have been included with those of the Corporation from
the closing date.

On March 6, 1994, the Corporation entered into an Agreement
and Plan of Merger with the Grumman Corporation and on March
8, 1994, the Corporation made an offer to purchase for cash
all outstanding shares of common stock of Grumman Corporation.
Subsequently, Grumman reached agreement with and accepted
Northrop Corporation's competing offer to purchase its
outstanding common shares.   Martin Marietta Corporation
received $50 million, plus reimbursement of expenses, from
Grumman pursuant to the termination provisions of the March 6,
1994, Agreement and Plan of Merger.  The $50 million payment
is included in other income and expenses, net for the nine
months ended September 30, 1994.

In February 1994, Martin Marietta Materials, Inc. sold through
an underwritten initial public offering, approximately 8.8
million shares of its common stock.  After the public sale,
the Corporation owns approximately 81% of the outstanding
stock of the company.  A portion of the proceeds from the
offering was used to defease in-substance certain long-term
debt of Martin Marietta Materials (See Notes 5 and 7). The
Corporation, through its subsidiary Martin Marietta
Technologies, Inc., recognized an after-tax gain of $70.2
million, or 56 cents per share fully diluted, from Materials'
initial public offering, net of the after-tax loss on the debt
defeasance of $4.7 million.

On November 22, 1992, Martin Marietta Corporation entered into
a Transaction Agreement with General Electric Company (GE) to
combine the aerospace and certain other businesses of GE
(collectively, the "GE Aerospace businesses") with the
businesses of Martin Marietta Corporation in the form of
affiliated corporations.  The transaction (the "GE
Transaction"), was consummated on April 2, 1993, and GE
Aerospace operations have been included in the consolidated
financial statements since that date.

             Third Quarter and Nine Months Ended September 30, 1994 and 1993

LIQUIDITY AND CAPITAL:  Net cash flow provided by operating
activities during the first nine months of 1994 was $478
million, compared with $238 million provided by operating
activities in the same period of 1993.  The 1994 cash flow
results from earnings, depreciation, and deferred taxes which
exceeded working capital increases, due principally to the
increase in receivables and decrease in accounts payable in
the first nine months.  The 1993 net cash flow was principally
from earnings, before deducting depreciation and the noncash
charge resulting from the adoption of accounting changes for
post-retirement and post-employment benefits, net of tax
payments and certain working capital changes.  Net capital
expenditures were $135 million in 1994 and $101 million in
1993 during the first nine-month periods.  Acquisition
activities during the second quarter of 1994 (General
Dynamics' Space Systems acquisition and the Grumman
agreement termination fee) resulted in a net use of funds of
$110 million. Net proceeds, after expenses, of $189 million
were generated from the first quarter 1994, initial public
offering of Martin Marietta Material's common stock.  Cash
of $136 million was used to defease in-substance $125 million
of 9.5% Notes due in 1995.

Martin Marietta's internal cash flows and access to capital
markets are expected to continue to be sufficient to provide
the capital resources necessary to support operating needs and
cover debt service requirements.  The Corporation's
outstanding public senior debt (which is issued through Martin
Marietta Technologies, Inc. and guaranteed by Martin Marietta
Corporation) is rated A by Standard & Poor's, A3 by
Moody's,and A by Duff & Phelps.  Martin Marietta's commercial
paper ratings are A-1 by Standard & Poor's, P-2 by Moody's,
and Duff-1 by Duff & Phelps.  Martin Marietta Corporation's
and Martin Marietta Technologies, Inc.'s principal borrowing
facility is an $800 million revolving credit facility which
expires on March 31, 1996.  This borrowing facility may be
used for general corporate purposes. At September 30, 1994,
there was no amount outstanding under the credit facility. If
the proposed merger with Lockheed Corporation is consummated,
it is anticipated that Martin Marietta's existing credit
facility will be terminated effective immediately prior to
consummation of the merger and that Lockheed Martin
Corporation will obtain its own credit facility.

Martin Marietta Technologies, Inc., has a shelf registration
on file with the Securities and Exchange Commission for the
offering of up to $300 million in debt securities which may be
issued from time to time.  Such debt securities would be
obligations of Martin Marietta Technologies, Inc., and would
be fully and unconditionally guaranteed by Martin Marietta
Corporation.  The Corporation's ability to issue such debt
securities at any given time is dependent, among other
things, upon market conditions.

Under a 1993 authorization from the Board of Directors, the
Corporation may repurchase approximately 32.4 million of its
common shares for use in connection with the Corporation's
Amended Omnibus Securities Award Plan, Performance Sharing
Plan and for general corporate purposes. There have been no
share repurchases made pursuant to this authorization.

RESULTS OF OPERATIONS:  Net sales increased $96 million, or
4%, in the third quarter of 1994 over the comparable period in
1993 , while nine-month 1994 sales increased $839 million, or
13%, over the same period a year ago.

The Electronics Group had sales of approximately $2.9 billion
in the first nine months of 1994. The Group's sales increased
3% in the third quarter and 9% in the nine months of 1994 over
the same periods in 1993. The Group's gains in the first
nine months of 1994 reflect primarily the sales performance of
Ocean & Radar Systems and Government Electronics Systems.

Space Group, with nine-month 1994 sales of approximately $2.4
billion, had sales increases of 14% in the third quarter and
9% in the first nine months of 1994 over the comparable
periods in 1993.  The Group's third quarter sales reflect
increases from each of its operating units.  Sales in the
nine-month period from the Group's Astro Space unit more than
offset revenue declines from the Group's Astronautics unit.
The Group's results include the operations of the former
Space Systems division of General Dynamics which was acquired
by the Corporation on May 1, 1994.

Information Group, with sales of $1.1 billion in the first
nine months of 1994, had sales increases of 8% in the third
quarter and 40% in the first nine months of 1994 over the
comparable periods of 1993. For comparison purposes, the
Group's 1993 sales were adjusted to reflect a 1994 change in
the method of recording intercompany activities related to the
Group's Internal Information Systems unit.  This change had no
effect on the Corporation's consolidated net sales.  The sales
performances of the Group's Management & Data Systems and
Automated Systems units were the principal reason for the
sales gain in the first nine-month period of 1994.

Services Group had sales of $348 million in the first nine
months of 1994. The Group's sales declined by $33 million in
the third quarter of 1994 from the same period sales a year
ago. In the first nine months of 1994, Services Group sales
increased by $36 million over the sales in the comparable
period of 1993.

           Third Quarter and Nine Months Ended September 30, 1994 and 1993


Martin Marietta Materials, Inc. had sales of $377 million in
the first nine months of 1994, representing increases of 12%
in the third quarter and 13% in the first nine months of 1994
over the comparable periods of 1993.  Sales for the aggregates
operation were up 15% in the quarter and 16% during the first
nine months, and were the reason for this Group's overall
increase.

Earnings from operations were up $47 million, or 21%, in the
third quarter and $159 million, or 28%, in the first nine
months of 1994 over 1993.  Electronics Group operating profits
increased 24% in the third quarter and 30% in the first nine
months of 1994 compared with the same periods of 1993.  The
Group's 1994 operating profits were adversely affected by a
provision of $53 million in the first six months to cover
additional costs on the Aero & Naval Systems' Pratt &
Whitney jet engine thrust reverser program.  These additional
estimated costs are associated with initial production
start-up problems and certain continuing redesign efforts.
Pratt & Whitney and the Corporation have agreed that
production thrust reversers being delivered to Pratt & Whitney
are being conditionally accepted subject to reservations of
rights by each corporation.  Management believes that current
financial reserves are adequate for this program based on
information and conditions known at this time.  The Group's
overall operating profit gains in the first nine months of
1994 reflect the performance of the Armament Systems,
Electronics & Missiles, Government Electronics, and
Ocean & Radar Systems units which more than offset the impact
of the charge taken on the Pratt & Whitney program.

Space Group profits grew 39% in the third quarter and 19% in
the first nine months of 1994 compared with the comparable
periods a year ago.  The Group's third quarter and nine-month
results are principally due to profit gains by its Astro Space
unit.

The Information Group operating profits declined 36% in the
third quarter and increased 17% in the first nine months of
1994 over the same period in 1993.  The third-quarter decrease
was due to lower profits principally because of award fee
timing, in the Group's Air Traffic Systems and Management &
Data Systems units.  The nine months gain are principally
attributable to the performance of the Group's Management &
Data Systems and Automated Systems units.  Services Group
operating profits declined $ 3 million in the third quarter
and rose $3 million in the first nine months of 1994 over
1993.

           Third Quarter and Nine Months Ended September 30, 1994 and 1993


Martin Marietta Materials Inc.'s operating profits
increased by 15% in the third quarter and 26% in the first
nine months of 1994 over the comparable periods.  The profit
gains result primarily from the performance of the company's
aggregates operation.

Other income and expenses, net, for the nine months
ended September 30, was $195 million in 1994 compared
with $39 million in 1993. The increase in 1994 was due
principally to the pre-tax gain of $118 million which
resulted from the Martin Marietta Materials' initial public
offering and the $50 million received from Grumman pursuant to
the termination provisions of the March 6, 1994, Agreement
and Plan of Merger.

Interest expense decreased $5 million in the third quarter
and increased $10 million in the first nine months of
1994 over 1993.  The decrease in the third quarter is
primarily because the Corporation defeased in-substance
$328 million of notes ($125 million of 9.5% Notes during
February 1994 and $103 million of assumed GE payment
obligations during December 1993).  The increase in the first
nine months of 1994 is due to the $1.4-billion increase in the
Corporation's long-term debt during the second quarter of
1993.  The Corporation issued $700 million in long-term debt
in April 1993, and assumed $750 million of GE payment
obligations (including approximately $16 million of accrued
interest) in connection with the GE Transaction.

The Corporation's effective income tax rate for the first nine
months was 40.7% in 1994 and 37.6% in 1993.  The effective
rates in both years are higher than the statutory corporate
federal income tax rate principally due to differences
between book and tax accounting arising from the amortization
of goodwill associated with the GE Transaction and state
income taxes.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

On August 29, 1994, Martin Marietta Corporation
("Martin Marietta") and Lockheed Corporation ("Lockheed")
entered into a definitive Agreement and Plan of Reorganization
that will, assuming that the transaction contemplated therein
(the "Combination") is consummated, result in Martin Marietta
and Lockheed becoming separate subsidiaries of a newly formed
holding company called Lockheed Martin Corporation.  Martin
Marietta is a party to a number of lawsuits relating to the
Combination.  Class certification has been requested in each
suit.

Lockheed, Martin Marietta and the directors of Lockheed
are parties to three lawsuits filed in the Superior Court of
the State of California (i) Richard Rampell and Frederick Rand
v. Daniel M. Tellep, et al., (filed August 31, 1994); (ii)
Stanton Discount Pharmacy, Inc. v. Daniel M. Tellep, et al.,
(filed September 12, 1994); and (iii) Rose Hadian v. Daniel M.
Tellep, et al., (filed October 27, 1994) and one lawsuit filed
in the Court of Chancery of the State of Delaware, Daniel
Lifshitz v. Lockheed Corporation, et al., (filed September 26,
1994).  Martin Marietta, Lockheed and the directors of Martin
Marietta are parties to an additional lawsuit filed in the the
Superior Court of the State of California, Doris R. Fish v.
Marcus C. Bennett, et al., (filed October 26, 1994).

Each of these lawsuits generally alleges the breach, or
aiding and abetting a breach, of various fiduciary duties.  In
particular, the lawsuits focus, among other things, on the
alleged unconscionability and gross unfairness of the
consideration to be offered in the Combination, alleged
director self-dealing and conflicts of interests, the alleged
negative effects of the $100 million termination fee and the
alleged duty to maximize stockholder value via an auction,
open bidding or other "market check" mechanism.  The lawsuits
also seek similar relief, generally in the form of a request
that the Combination be enjoined, the entry of an order
directing the directors to carry out their fiduciary duties,
and a request for unspecified monetary damages.  Martin
Marietta (and, with respect to the Fish suit, Martin
Marietta's directors) intends to contest the claims asserted
in these suits on, among other grounds, the fact that the
Combination is a "merger of equals," does not involve the sale
of the either Lockheed or Martin Marietta and that,
consequently, no auction is required.

In late June 1994, Martin Marietta received a subpoena from
the Department of Defense Inspector General's Office for
documents related to Martin Marietta's Compu-Scene image
generator product.  The Government appears to be investigating
the exemption for and/or waiver of the submission of cost or
pricing data.  Martin Marietta is responding to the subpoena
and is negotiating with the Government with respect to a
number of issues associated with document production.
