Haven-class hospital ship

The Haven class of hospital ships were built for the United States Navy (USN) during World War II. Haven-class ships also served in the Korean War and the Vietnam War. They were among the first ships to be able to receive casualties directly by helicopter and were the first fully air conditioned ships in the US Navy.

The last Haven class ship was struck from the Naval Vessel Register in 1989. One ship sank in a collision in 1950; four others have been scrapped. The last Haven-class ship, the ex-USS Sanctuary (AH-17) was scrapped in 2011. Haven-class hospital ships were replaced with the Mercy-class hospital ships.
