Looks like the LSM concept may just happen after all…
The Damen LST 100 design, which was picked last December to be the Navy LSM– coming to a shipyard near you
TOTE Services in Jacksonville yesterday picked up a $2.6 billion contract from Naval Sea Systems Command’s PAE Maritime to serve as Vessel Construction Manager (VCM) for the McClung-class Medium Landing Ship (LSM) program, with the first hull to be delivered by 2029.
You know, the mini-LSTs that the Navy is building for the Marines to shuttle NMESIS missile batteries and light armor around the Western Pacific in a sea-denial-from-the-shore kind of philosophy, setting up what are now termed as a “Marine Corps fires expeditionary advanced base.”
A Navy Marine Expeditionary Ship Interdiction System launcher, a command and control vehicle, and a Joint Light Tactical Vehicle are transported by a U.S. Navy Landing Craft Air Cushion from Pacific Missile Range Facility Barking Sands, Hawaii, out to U.S.S. San Diego, Aug. 16, 2021. The movement demonstrated the mobility of a Marine Corps fires expeditionary advanced base, a core concept in the Marine Corps’ Force Design 2030 efforts.

The contract will cover management of constructing the first eight LSMs, with a program of record for up to (hold your breath) 35 of the baby phibs built to the Damen LST 100 double-ended Ro/Ro design.
This thing:
Via Damen:
The LST100 is 100.68 metres (330 feet) long with a beam of 16 metres (52 feet) and a draught of 3.58 metres (12 feet). It is suited to a diverse range of operations. With its ability to transport personnel, vehicles, equipment and cargo, the vessel can be used in patrol, landing, survey and reconnaissance operations, as well as for the delivery of humanitarian aid & disaster relief.
In its standard design, it features bunks for 282 personnel. Cargo can be transported on the RoRo deck (500m2), vehicle deck (400m2) and on the helicopter deck. The vessel is able to sail at speeds of up to 14 knots, with an endurance of 3,890 nautical miles. At an endurance speed of 10 knots, it can reach up to 7,530 nautical miles.
The LST100 features extensive flexibility. Its modular design enables straightforward adaptation and upgrade without compromising the benefits of standardization. For example, with the addition of a standard, 20-metre modular block, the vessel can be enlarged to the LST120 design during construction.
Besides the intended purpose and general use as a ‘phib, the LSMs have an obvious use in Over The Horizon – Special Forces (OTH-SF) operations, stand-off Mine Counter Measures (MCM) operations support, and as a general helicopter/UAV “lilipad.”
Now, to be clear, TOTE is not actually going to build the LSMs, simply award and manage shipbuilder contracts- you know, something NAVSEA should be capable of doing, but in program after program has proven absolutely incapable of doing so. Looking at you, FFG and LCS programs.
