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. The significant milestone was celebrated at a ceremony held on December 18, 2025, at the company’s ship manufacturing facility in Mobile, Alabama. 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 the US Marine Corps. They are designed to transport vehicles, personnel, and cargo between amphibious assault ships and the shore, facilitating a range of military operations. These vessels are essential connectors that enhance the Navy’s ability to execute missions effectively.
Design and Capabilities of the New LCUs
The new LCUs feature a roll-on/roll-off monohull configuration, equipped with hydraulically controlled bow and stern ramps. This design allows for multiple vessels to connect and create a causeway, enabling fast and secure loading and unloading operations. According to Austal, the LCUs can be transported within the well decks of amphibious assault ships, making them versatile assets in naval operations.

Each LCU is capable of carrying loads up to 3.5 meters high above the vessel’s vehicle deck. With a crew of 13, these vessels can conduct independent open ocean transits and operations at sea. They boast a range of 1,200 nautical miles and can reach a top speed of 11 knots, making them efficient for various missions.
The first LCU from this series was launched in August 2025, marking the beginning of a new chapter in the Navy’s amphibious capabilities. The ongoing construction of LCU 1713 underscores Austal USA’s commitment to delivering mission-ready ships that meet the evolving needs of the US military.
As the construction progresses, the Navy anticipates that these LCUs will significantly enhance its operational readiness and logistical capabilities, ensuring that troops and equipment can be deployed swiftly and effectively in various scenarios.
