US Navy Expands Shipbuilding Options with Prototype LCU-1700 Awards

The U.S. Navy has awarded contracts for the construction of seven Landing Craft Utility (LCU) vessels to three Gulf Coast shipyards as part of a $280 million deal aimed at expanding production and modernizing amphibious warfare capabilities. According to USNI News and Naval Today, the contract was announced on September 15, 2026.

Shipyard Selection and Contract Details

The shipyards selected for this prototype agreement are Conrad Shipyard, LLC of Orange, Texas; Master Boat Builders, Inc. of Coden, Ala.; and Saronic Technologies of Brownsville, Texas. Each firm will construct two or three LCUs under the $280.5 million deal, according to Naval Today.

The LCU-1700 is a significant upgrade over the legacy LCU 1610 class, offering improved reliability and increased payload capacity. The Navy's fiscal year 2026 budget documents indicate that each LCU will average approximately $25 million in cost, as reported by USNI News.

Prototype Production and Future Implications

The initial construction effort is valued at $280.5 million, with deliveries scheduled to begin in late 2028 and continue through 2029. The U.S. Navy has emphasized the importance of this contract as part of its strategy to validate a production-ready Technical Data Package (TDP), thereby reducing risk for high-rate production in the future.

The awards represent an expansion of shipbuilding options beyond traditional defense contractors, as Master Boat Builders and Conrad Shipyard are well-established commercial shipbuilders known for their workboats. Saronic Technologies is a startup with expertise in autonomous vessels, marking its first venture into series-production landing craft. This diverse selection reflects the Navy's desire to integrate multiple production lines to ensure robust and reliable manufacturing processes.

Technical Specifications and Operational Capabilities

The LCU-1700 class is designed for amphibious operations, resupply missions, and disaster-response scenarios. Each vessel will have a 170-ton payload capacity, allowing them to move troops, vehicles, and cargo from amphibious ships directly onto beaches or unimproved shorelines without the need for port facilities. With a range of about 1,200 nautical miles, these craft provide critical mobility in littoral environments.

This prototype phase is crucial as it will validate the TDPs through actual fabrication, ensuring a smooth transition to high-rate production once all issues are resolved. The initial production effort at these new shipyards aims to refine manufacturing plans and prepare for full-scale production of the LCUs, which are essential components in the U.S. Navy's modern amphibious warfare strategy.

What This Means for Operators

The expansion of shipbuilding options through contracts with non-traditional defense contractors brings several practical benefits to operators. Firstly, it ensures a diverse and resilient supply chain that can adapt quickly to changing requirements. Secondly, the involvement of innovative firms like Saronic Technologies could lead to more advanced and efficient manufacturing processes. Lastly, this initiative supports the broader naval strategy to modernize amphibious warfare capabilities while maintaining operational readiness.

For ship operators working with the U.S. Navy or other government agencies involved in amphibious operations, these new production lines mean a potentially increased availability of advanced LCU-1700 vessels, enhancing their ability to conduct complex maritime missions efficiently and effectively.
