Three manned ships were anchored near the blast site to measure the effects of the explosion. The ex-light cruiser USS ATLANTA, taken out of mothballs and refitted with special blast recording and measuring devices, served as primary test ship, accompanied by the guided missile destroyer USS COCHRANE and the Canadian destroyer escort HMCS FRASER. The ships were positioned to yards from the blast. 083 Five hundred tons of TNT piled up in a 17-foot hemispheric mound were used in the blast which simulated a one kiloton nuclear surface explosion. Prir to the detonation, a horizontal pattern of rockets were fired to provide smoke trails used in gauging the speed of the blast's shock wave. Date from the tests will be used by the Navy to evaluate present and planned "blast hardened" structures on board ship and by the Defense Atomic Support Agency, sponsor of the experiment, in studies of blast and shock effect over water.
