The U.S. Navy is preparing to resolve its long debate with the Marine Corps over the fate of the Landing Ship Medium (LSM), the amphibious force’s small transport for inter-island warfare in the Pacific. On April 7, Naval Sea Systems Command quietly issued notice that it plans to award Bollinger a sole-source contract to build one lead-ship LSM based on the U.S. Army’s Gen. Frank S. Besson-class.
The ship that the U.S. Navy plans to buy is based on a revised version of the Army design that Bollinger-owned VT Halter built for the Israeli Navy. In Israeli service, this variant makes 14 knots with a cargo of up to 2,000 tonnes in deep-draft pier-to-pier mode, with a lesser payload for beaching operations. The design has a bow visor for better seakeeping in open water, rather than the original Besson-class’ flat ramp.

The class also has a stern ramp that can be used to load and offload while Med-moored at a pier. In U.S. Army service, the ramp facilitates drive-through ro/ro cargo transloading for the complex Joint Logistics Over The Shore (JLOTS) transfer system.
Unless it is to be heavily modified, the IDF’s Besson variant does not have a suite of high-end air defense or surface warfare weaponry. The long Navy-Marine Corps fight over the LSM’s fate hinged on whether there would be a few highly survivable and very expensive hulls – the Navy’s preference – or whether there would be a large number of less expensive ships built to a less stringent standard, as the Marine Corps demanded. The Besson-class appears to land further towards the Marine Corps’ version: it is serviceable enough to be the primary landing and logistics ship for the U.S. Army, and for the Israeli Navy, but it is not an exquisite naval weapons platform (unless up-armed).
As first reported by USNI, NAVSEA is also buying the technical data package for the Damen LST 100, a popular landing ship design of comparable size and specifications – but equipped with an enclosed foredeck and an aft helideck. The LST 100 is in use by the Nigerian Navy and was recently ordered by the Australian Army.
