War Department calls it a cosmic bomb.
Terminology is still being defined. Yesterday is was an automic bomb in Nimitz report. Today it is a cosmic bomb.

“Cosmic bomb” was another name for the atomic bomb. It was used for a short period of time in 1945 and 1946. The first New York Times story about the bombing of Hiroshima referred to “this terrible new weapon, which the War Department also calls the ‘Cosmic Bomb.’”[1] Another articles noted that “what the Army has called the ‘cosmic bomb’ was not regarded by those responsible for winning the war against Japan as the factor which, of itself, would give the war its finishing touch”,[2] and a headline reported “Secret War Nipped Reich Cosmic Bomb.”[3]
Thomas Pynchon uses the phrase several times in his 1973 novel Gravity’s Rainbow, which is set roughly in the period during which the term was current.
The term rapidly fell into disuse as applied to weaponry, soon yielding to “atomic bomb”
But I didn't really understand warp drive until Scotty explained it to me.
