Landing Ship Medium (LCM) were amphibious assault ships of the United States Navy in World War II. Of a size between that of Landing Ships Tank (LST) and Landing Craft Infantry (LCI), 558 LSMs were built for the USN between 1944 and 1945. The majority 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.

Legacy

One LSM, USS LSM-45, survived in its original configuration until around 2010. It was in storage at Marine Station Camp Lejeune in Jacksonville, NC. It was slated to become the centerpiece of the Museum of the Marine, but due to changed plans was scrapped between 2010 and 2014.
