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 Ship, Tank|Landing Ships Tank]] <!-- (LST) --> and [[Landing Craft Infantry]]<!-- (LCI) -->, 558 LSMs were built for the USN between 1944 and 1945. Most of the vessels built on this frame were regular transports, but 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.

OPNAV N95 established a new LSM program in 2020. The new LSM will be {{convert|350| to| 400|ft}} long, able to operate at 22 knots and have a range of {{convert|6500| mile}}. The cost will be much lower than traditional amphibious shipping, according to a story in the March 2023 ''Marine Corps Gazette''.  The piece suggests that a MLR (Marine Littoral Regiment) would need nine LSMs.<ref>{{Cite web|url=https://www.cbo.gov/publication/60208|title=Acquisition Costs of the Navy’s Medium Landing Ship |date=11 April 2024|website=Congressional Budget Office}}</ref><ref>{{Cite web|url=https://insidedefense.com/daily-news/navy-launches-lsm-contract-competition|title=Navy launches LSM contract competition |website=InsideDefense.com}}</ref><ref>{{Cite web|url=https://www.defensenews.com/naval/2022/10/05/marines-navy-near-agreement-on-light-amphibious-warship-features/|title=Marines, Navy near agreement on light amphibious warship features|first=Megan|last=Eckstein|date=5 October 2022|website=Defense News}}</ref> As a comparison the [[Jason-class tank landing ship|''Jason''-class]] of the Greek Navy is about {{convert|380|ft}} long, with a top speed of 18 knots

==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 [[Ship breaking|scrapped]] between 2010 and 2014.{{citation needed|date=January 2022}}

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).<ref name=USNI_20230214>{{cite news|title=Marine Corps Requirements Call for 9 Light Amphibious Ships per Regiment |date=February 2023 |first=Mallory |last=Shelbourne |url=https://news.usni.org/2023/02/14/marine-corps-requirements-call-for-9-light-amphibious-ships-per-regiment |newspaper=USNI News |publisher=United States Naval Institute }}</ref><ref name=USNI_20230222>{{cite news|title=SECNAV Del Toro 'Excited' About New Landing Ship Mediums |date=February 2023 |first=John |last=Grady |url=https://news.usni.org/2023/02/22/secnav-del-toro-excited-about-new-landing-ship-mediums |newspaper=USNI News |publisher=United States Naval Institute }}</ref>
