World War II was won and lost in the seas in both the Pacific campaign and the defense of London. That means that a lot of ships were built and sank. Eventually, they stopped running out of cool names and had to resort to things like the HMS Porcupine, that was later renamed after it was sank.
The HMS Porcupine was a P-class destroyer that was built on the River Tyne. It was ordered in October 1939 and launched on June 10, 1941. After being commissioned in August 1942, it was almost torpedoed by a German U-Boat in December. It was escorting ships from Gibraltar to Algiers when it was hit by one of the four torpedos fired at the convoy.
The damage nearly split the ship in two and was considered a total loss. It was split in two halves to ship it back to London. Each piece received a new name: The front part became the HMS Pork and the rear became the HMS Pine. The destroyed ship was finally paid off on August 31, 1946 and was broken up off the coast of England in 1947.
