Austal USA Begins Construction of Fourth LCU for US Navy
Shipbuilder Austal USA has officially commenced construction on the fourth Landing Craft Utility (LCU) for the United States Navy at its facility in Mobile, Alabama. The significant milestone was marked by a ceremony held on December 18, 2025. This new vessel, designated LCU 1713, is part of a larger contract awarded to Austal in 2023, valued at $91.5 million, which includes the potential for up to twelve new LCUs.
The LCUs play a crucial role in the operational capabilities of the US Navy and Marine Corps. They are designed to transport vehicles, personnel, and cargo between amphibious assault ships and shore locations. These vessels are essential for various military operations, ensuring that troops and equipment can be deployed effectively in diverse environments.
Technical Specifications and Capabilities
The LCU 1713 features a roll-on/roll-off monohull configuration, equipped with hydraulically controlled bow and stern ramps. This design allows multiple vessels to connect and create a causeway, facilitating rapid and secure loading and unloading operations. Each LCU can carry loads up to 3.5 meters high above the vessel’s vehicle deck, making them versatile for various mission requirements.
With a crew of 13, these vessels are capable of independent open ocean transits and can operate at sea with a range of 1,200 nautical miles. The LCUs can achieve a top speed of 11 knots, making them efficient for transporting troops and equipment to and from the battlefield. The first LCU in this series was launched in August 2025, showcasing Austal’s commitment to delivering mission-ready ships to the Navy.
The construction of LCU 1713 not only signifies Austal’s ongoing partnership with the US Navy but also highlights the importance of modern amphibious capabilities in contemporary military operations. As the demand for agile and effective maritime transport solutions continues to grow, the LCUs will play a vital role in enhancing the operational readiness of the US armed forces.
