US Navy selects HII’s REMUS 300 for next-generation SUUV program


The United States Navy has selected the Huntington Ingalls Industries (HII) REMUS 300 unmanned underwater vehicle (UUV) for the small, next-generation UUV program.

The SUUV registration program is facilitated by the Defense Innovation Unit (DIU), which is part of the United States Department of Defense (DoD).

HII’s selection follows the completion of a two-year rapid prototyping effort, which also included a number of user evaluations and spiraling upgrades to improve the REMUS 300 design.

The next-generation SUUV program, also known as Lionfish, will replace the Mk18 Mod 1 Swordfish program, based on the REMUS 100 design.

HII President and CEO Chris Kastner said, “This program demonstrates the value of our investment in autonomous and unmanned systems, and our customer knowledge.

“We are confident that these technologies will both support the Navy’s mission and enhance force effectiveness in all areas.”

The first phase of the program will see the company manufacturing REMUS 300 UUVs and carrying out tests over the next year.

Developed by Hydroid, a subsidiary of HII, the SUUV combines an open architecture in a compact and portable design.

With endurance options of up to 30 hours and the ability to dive to depths of 305m, REMUS 300 technology can perform various critical underwater missions.

The vehicle’s primary missions include hydrographic surveying, search and recovery, anti-submarine warfare, mine countermeasures, surveillance and reconnaissance, among other operations.

HII Mission Technologies Division Unmanned Systems Business Group President Duane Fotheringham said, “REMUS UUVs have extended the capabilities of the warfighter since they were first used in combat during the Operation Iraqi Freedom in 2003.

“We have improved, matured and refined this technology since then, and we are delighted that the REMUS 300 meets the needs of the Navy’s next-generation UUV program.”

In June last year, HII received a contract from the Royal New Zealand Navy to supply four REMUS 300 SUUVs.
