A Landing Ship Medium (LSM) was originally an amphibious assault ship of the United States Navy in World War II. Of a size between that of Landing Ships Tank and Landing Craft Infantry, 558 LSMs were built for the USN between 1944 and 1945. Most of vessels built on this frame were regular transports, while several dozen were converted during construction to specialized roles. Most LSMs were scrapped during the Cold War, but several were sold by the United States Department of Defense to foreign nations or private shipping companies.

LSM(R)-190 took part in the Battle of Okinawa from 7 April–4 May 1945. She was hit and sunk by a Japanese suicide plane on 4 May 1945 while on the radar picket line. She later received a Navy Unit Commendation for her service off Okinawa.
USS LSM-45 was a LSM-1-class medium landing ship built for the United States Navy during World War II. The ship also served as Ypoploiarchos Grigoropoulos (L161) in the Hellenic Navy from 1958 to 1993. She was the last known surviving LSM in its original configuration. Her last location before scrapping was Marine Corps Base Camp Lejeune in North Carolina. LSM-45 was donated to the Museum of the Marine by the now defunct Amphibious Ship Museum under the understanding that it would be put on display at the museum, and was towed to North Carolina in 2004 from Omaha, Nebraska. The museum decided in 2007 that the ship would not be a part of the museum and tried looking for another home for the ship. In 2009, there were reports that the Museum was considering scrapping or sinking the ship as an artificial reef, and she was scrapped sometime between 2010 and 2014.
