                             EXPLANATORY STATEMENT
                             ---------------------


     On January 28, 1996, Lockheed Martin Corporation (the "Corporation")
consummated an internal reorganization pursuant to which its wholly owned
subsidiaries, Martin Marietta Technologies, Inc., Martin Marietta Corporation,
Lockheed Sanders Corporation, Lockheed Missiles and Space Company, Inc. and
Lockheed Corporation, were merged in a series of transactions into the
Corporation.  As a result, the businesses previously conducted by those former
subsidiaries and the Corporation are now conducted by the Corporation.  On
February 8, 1993, Lockheed Corporation filed a Registration Statement on Form S-
3 (Reg. No. 33-49327) (the "Registration Statement") registering Lockheed
Corporation debt securities with an initial offering price of $2,000,000,000 in
the aggregate (the "Debt Securities").  Of the total aggregate amount of Debt
Securities so registered, Debt Securities with an aggregate initial offering
price of $1,537,500,000 have been issued as of the date of this Post-Effective
Amendment.  This Post-Effective Amendment to Form S-3 removes from registration
the remaining Debt Securities issuable pursuant to the Registration Statement.
