25. Memorandum From the President’s Assistant for National Security Affairs (Brzezinski) to Secretary of State Vance1


  • U.S. Position Regarding Anti-Satellites (ASAT)

The President has signed a Presidential Directive calling for the removal of the restriction on operational or space based testing. He has authorized the Secretary of Defense to pursue, for planning purposes, a U.S. ASAT development program encompassing that testing in space or against U.S. objects in space deemed essential to achieve an ASAT capability.

All other elements of my Arms Control for Anti-Satellite Systems memorandum dated September 23, 1977, remain in effect at this time.
