DTC Test 74-030 was designed in response to Army and Navy requirements, AR-6 and NA-5, to determine biological effects in a variety of environments. Initial FY 74 planning documentation indicated that it would be executed in FY 74 as a follow-on to DTC Test 70-74.¹ FY 75 planning documentation added the parenthetical notation that DTC Test 74-030 fell under the revised research and development program T410A that included effects of environmental factors on biological decay. It further indicated that work would continue into FY 75.² The Deseret Test Center, headquartered at Fort Douglas, Utah, closed in 1973, before DTC Test 74-030 could be conducted; the test is therefore presumed to have been cancelled.
