Tests
Antler
Antler was the first shot fired as part of the resumption of nuclear testing by the United States. Fired 15 September 1958, containment was immediately lost when the shot vented via the tunnel portal, destroying much of the test data. This was a recurring problem for tunnel tests of the era. The problem was thought to be caused by water above the blast zone draining into the explosion cavity where it was vaporised and escaped as steam.
Shrew
Shrew was the first Los Alamos test after the resumption of testing. The device was buried to a depth of in a canister long. The shaft was wide, lined with steel, and backfilled with sand to above the canister and concrete to the surface. Post-test, some radioactivity was detected by sampling aircraft.
British tests
Some accounts include the first British nuclear weapons test at the Nevada Test Site, shot ''Pampas'', as part of Nougat.
