US Navy Expands Shipbuilding Options for LCU-1700 Prototypes

The U.S. Navy has announced the selection of three new Gulf Coast shipyards to build seven prototype Landing Craft Utility (LCU) 1700 vessels, marking a significant step in expanding production options and modernizing amphibious warfare capabilities. The contracts were awarded to Conrad Shipyard LLC, Master Boat Builders Inc., and Saronic Technologies, all based in Texas and Alabama.

Contract Details and Process

According to USNI News and Naval Today, the overall contract is valued at $280 million and includes the construction of seven LCUs. Each shipyard will be responsible for building two or three prototype craft as part of an effort to refine manufacturing plans ahead of high-rate production. The LCU-1700 program aims to replace the aging LCU 1610 class, with each new vessel featuring improved reliability and increased payload capacity.

The contract is funded through the One Big Beautiful Bill Act (OBBBA), which allows for prototype authorities under Section 4022 of Title 10 U.S.C. This approach is designed to speed up delivery of littoral capabilities, validate a production-ready Technical Data Package (TDP), and expand the number of available production lines.

Shipyard Roles

Conrad Shipyard LLC, based in Orange, Texas, has extensive experience in commercial shipbuilding. Master Boat Builders Inc., located in Coden, Alabama, is known for its workboat construction. Saronic Technologies, headquartered in Brownsville, Texas, will be utilizing its new mega-facility, Port Alpha, which focuses on autonomous vessel production.

Master Boat Builders and Conrad Shipyard have established track records with the U.S. Navy, while Saronic Technologies is making its debut as a manufacturer of LCU vessels at its new facility in Texas. This marks the first build for both Saronic and Port Alpha, which will serve as a stepping stone to higher production rates.

Manufacturing Process and Prototypes

The initial construction effort under these contracts is expected to begin in late 2028 with deliveries scheduled through 2029. The Navy aims to use the prototypes to validate the TDPs, ensuring a smooth transition to high-rate production.

According to Fatima Bahtic at Naval Today, "Under the agreements, each shipyard will construct two or three prototype craft and refine its manufacturing plans ahead of high-rate production." This process is crucial for ensuring that the LCU-1700 vessels meet the Navy's requirements before full-scale production begins.

The LCU 1700 class is a significant upgrade from the legacy LCU 1610, with improved reliability and increased payload capacity. These vessels are designed to enhance amphibious operations, resupply missions, and disaster-response efforts. Each LCU 1700 will feature a 170-ton payload capacity, allowing for the movement of troops, vehicles, and cargo from ships offshore directly onto a beach or unimproved shoreline.

Impact on Operators

This expansion in shipbuilding options is expected to provide greater flexibility and competition within the naval construction industry. For operators, this means potential access to more diverse and innovative solutions for their amphibious warfare needs. The LCU-1700 program will likely lead to improved reliability and efficiency in logistics operations, with the new vessels offering enhanced capabilities compared to their predecessors.

The Navy's focus on rapid prototyping through prototype authorities under OBBBA underscores its commitment to modernizing its fleet swiftly while maintaining robust quality control. This approach is expected to streamline the production process, ultimately delivering better-equipped and more capable vessels to support ongoing military operations and future missions.
