when was the last battleship built

The last true battleship ever completed was the British HMS Vanguard, finished and commissioned shortly after World War II in 1946. The last battleship launched and commissioned by the United States was USS Missouri (BB‑63) in 1944.

Key dates

• HMS Vanguard, generally regarded as the last battleship ever built, was completed and entered service in 1946 with the Royal Navy.

• USS Missouri, the final U.S. battleship to be launched and commissioned, joined the fleet in 1944 during World War II.

Why this is considered “the last”

• After Vanguard, no navy completed any new battleships, as naval doctrine shifted toward aircraft carriers, submarines, and missile ships.

• Existing battleships served for some decades (for example, Vanguard until 1960 and the Iowa‑class in later conflicts) but they were modernized older hulls, not newly built designs.
