Damen’s LST100 Design Chosen for US Navy
Damen Shipyards Group has secured a significant contract with the Naval Sea Systems Command (NAVSEA) for its Landing Ship Transport (LST) 100 design. This selection marks a pivotal step in the US Navy’s Medium Landing Ship (LSM) program, which aims to bolster the transportation and landing capabilities of Marine Corps units in challenging environments. Up to 35 LST100 vessels will be constructed at American shipyards, enhancing the Navy’s operational readiness.
Proven Design and Rapid Development
The journey to this selection began when NAVSEA issued a Request for Information (RFI) to the industry in early 2025. Following this, Damen received a Technical Data Package (TDP) award from NAVSEA in July for the LST100 design. The Navy’s decision to choose the LST100 as the foundation for the LSM class stems from its proven track record and the urgent need for a non-developmental sea-going vessel design. Damen previously delivered an LST100, allowing NAVSEA representatives to inspect an operational model firsthand.
In addition to its success with the US Navy, the LST100 has also been selected by the Australian Government for its Landing Craft Heavy program, with plans to construct up to eight vessels in Australian shipyards. This international recognition underscores the LST100’s versatility and reliability in various military applications.

Versatile Capabilities and Future Prospects
The LST100 measures 100.68 meters in length, with a beam of 16 meters and a draught of 3.58 meters, making it suitable for a wide range of operations. Its design allows for the transportation of personnel, vehicles, equipment, and cargo, enabling its use in patrol, landing, survey, reconnaissance, and humanitarian missions. The vessel can accommodate up to 282 personnel and features a RoRo deck of 500 square meters, a vehicle deck of 400 square meters, and a helicopter deck.
With a maximum speed of 14 knots and an impressive endurance of 3,890 nautical miles, the LST100 is designed for long-range missions. Its modular design allows for easy upgrades, including the potential expansion to the LST120 configuration during construction. Damen’s Area Manager for the Americas, Alan Borde, expressed enthusiasm for the collaboration with American shipyards, emphasizing the long-standing relationships built over decades of support for ship construction.
This partnership not only strengthens the US Navy’s capabilities but also highlights Damen’s commitment to delivering reliable and efficient maritime solutions. The success of the LST100 could serve as a model for future projects, including the Offshore Patrol Vessel (OPV) program proposed for Romania, where Damen aims to leverage its experience and proven designs to meet NATO standards.
