Memorandum of Conversation between Roger C. Molander and M. Conze, 'Meeting with M. Conze of France, November 24, 1975'
Conze asked about the status of several French requests for nuclear assistance. These included their request for a CDC 7600 mainframe computer, the testing of reentry vehicle material, and technical help with the M-4 ballistic missile. Sonnenfeldt informed Conze that assistance with booster trigger design had not be authorized as it conflicted with US legal restriction in the Atomic Energy Act.
