USS Halibut

Two submarines of the United States Navy have been named USS Halibut, for the halibut, a large species of flatfish found on both sides of the Atlantic.

The first USS Halibut (SS-232) was a Gato-class submarine that saw action during World War II.

The second USS Halibut (SSGN-587), a unique nuclear-powered guided missile submarine designed to carry the Regulus missile, was an important part of the United States's deterrent force in the early years of the Cold War.
