DTC Test 71-75 was designed to evaluate the integrity of the chemical and biological defense systems of several critical CONUS national security sites. Originally planned as part of the FY 71 testing program, it was carried over to the FY 72 program. 1This is confirmed by the test's listing as the method of satisfying requirements CO-6 and SA-1 in a June 1971 planning document. 2 By March 1972, these requirements are listed in FY 74 planning documents as having been satisfied by two phases of study 71-160. 3 DTC Test 71-75 is therefore presumed to have been cancelled.
