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, North Carolina. It was slated to become the centerpiece of the Museum of the Marine, but due to changed plans, was scrapped between 2010 and 2014.

Light Amphibious Warship (LAW)

As of February 2023 the US Marine Corps has proposed the purchase of 18 to 35 modern LSMs; this LSM concept was previously known as the Light Amphibious Warship (LAW).
