JSC EXECUTES SPACE STATION WORK PACKAGE MODIFICATION


   The Johnson Space Center, Houston, has executed a 
supplemental agreement that provides for changed requirements 
to the Space Station Work Package 2 Design, Development, Test 
and Evaluation contract with McDonnell Douglas Space Systems 
Co., Huntington Beach, Calif.

   This modification adjusts the contract to include the 
results of the Space Station Freedom Program review activities 
of 1989, including the changes to requirements resulting from 
the Program Requirements Review that occurred in September and 
October of 1988, the Program Technical Audit of March 1989 and 
the Space Station Freedom Program Configuration Budget Review 
of October 1989.

   These activities resulted in lengthening by 17 months the 
Work Package 2 effort to June 30, 2000 and included such 
requirement changes as architectural control document updates, 
change from AC to DC power, addition of the responsibility for 
secondary power distribution, addition of the Avionics 
Development Facility, and a switch from hardware designed for 
flight to prototype such as dedicated test articles.

   The negotiated amount for the modification is $597 million 
making the new estimated value of the cost-plus-award-fee 
contract $3.5 billion.  The majority of the work will be 
performed at the McDonnell Douglas facilities in Huntington 
Beach and Houston.
