DTC Test 72-70 was designed to determine the vulnerability of coastal targets to offshore biological attack. As of the end of calendar year 1972, the test, also known under the revised research and development program as T405N, had been deferred pending approval from "higher headquarters." It is unclear whether conduct of this test would have required reconstitution of at least a portion of the previous Project SHAD fleet. Such an effort would have been hampered by the Marine Administration's 31 Jan 72 sale of the USS Granville S. Hall (YAG-40). The Deseret Test Center, headquartered at Fort Douglas, Utah, closed in 1973, before DTC Test 72-70 could be conducted; the test is therefore presumed to have been cancelled.
