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


     On March 15, 1995, Lockheed Martin Corporation (the "Corporation") filed
Registration Statement on Form S-8 (Reg. No. 33-58083) (the "Registration
Statement") registering 18,582,406 shares of Lockheed Martin Corporation Common
Stock for use in connection with the Lockheed Martin Corporation Performance
Sharing Plan (previously, the Martin Marietta Corporation Performance Sharing
Plan).  The Corporation anticipates combining that portion of the Lockheed
Martin Corporation Performance Sharing Plan relating to salaried employees with
another of the Corporation's plans, the Lockheed Martin Corporation Salaried
Savings Plan, later in 1997.  In anticipation of this combination, the
Corporation has divided the Lockheed Martin Corporation Performance Sharing Plan
into two parts, the first a continuation of the existing Lockheed Martin
Corporation Performance Sharing Plan in which hourly employees will continue to
participate (the "Plan") and the second, to be known as the Lockheed Martin
Corporation Salaried Savings Plan II (the "SSPII"), a continuation of that part
of the Lockheed Martin Corporation Performance Sharing Plan in which salaried
employees participate.  The SSPII and the Lockheed Martin Corporation Salaried
Savings Plan are collectively referred to as the "SSP."  As a consequence, the
Plan will use less shares in the future than the Corporation originally
anticipated when the Registration Statement was filed.  Accordingly, 17,282,406
shares of Lockheed Martin Corporation Common Stock previously registered by the
Corporation for use in connection with the Plan on the Registration Statement
and not already issued will not be issued in connection with the Plan by the
Corporation.

     Pursuant to the Corporation's undertakings in the Registration Statement
and in accordance with advice received by the Corporation from the Office of
Chief Counsel of the Division of Corporation Finance, the Corporation is filing
this Post-Effective Amendment No. 1 to the Registration Statement to remove from
registration under the Registration Statement the 17,282,406 shares of Lockheed
Martin Corporation Common Stock (together with related plan interests)
registered thereunder which will not be issued in connection with the Plan.
Simultaneously with the filing of this Post-Effective Amendment No. 1, the
Corporation is filing a Registration Statement on Form S-8 registering shares of
Lockheed Martin Corporation Common Stock for use in connection with the SSP. The
shares so registered will include that portion of the shares not issued in
connection with the Plan being deregistered hereunder. The remaining 1,300,000
shares of Lockheed Martin Corporation Common Stock (together with related plan
interests) registered pursuant to the Registration Statement are not being
deregistered pursuant to this Post-Effective Amendment No. 1 and shall remain
available for use in connection with the Plan.
