DTC Test 72-30 was designed to gather data to further characterize biological aerosol diffusion in a marine environment. As of the end of calendar year 1972, the test, also known under the revised research and development program as T400N, had been deferred pending approval from "higher headquarters." Conduct of this test would have also required reconstitution of a testing fleet since the USS Granville S. Hall (YAG-40) had been sold by the Marine Administration on 31 Jan 72. The Deseret Test Center, headquartered at Fort Douglas, Utah, closed in 1973, before DTC Test 72-30 could be conducted; the test is therefore presumed to have been cancelled.
