Operation Sailor Hat was a series of three massive, non-nuclear high-explosive tests conducted by the US Navy in 1965 on the rocky southwestern tip of Kaho'olawe, Hawaii. Each test detonated a dome-stacked 500-ton pile of TNT to simulate the blast effects of a nuclear weapon on naval ships.The primary goal of the trials was to test and improve the blast and shock resistance of modern warships, gathering crucial data on cratering, seismic activity, and electromagnetic interference.
