Landing Ship Medium

Landing Ship Medium were amphibious assault ships of the United States Navy in the World War II.

Of comparable size to Landing Ship, Tank and the Landing Craft, Infantry, there were 558 LSM (Landing Ship, Medium) made for the USN between 1944 and 1945. The majority of vessels built on this versatile frame were regular transports however there were several dozen that were converted during construction for specialized roles. Most vessels of this type were scrapped during the Cold War, but several were sold by the United States Department of Defense to foreign nations or private shipping companies.

Only one LSM, USS LSM-45 is known to still exist in its original configuration. It is 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, is now in danger of being scrapped or sunk as an artificial reef.
