Huntington Ingalls Industries (HII), America’s largest shipbuilder and a leading provider of all-domain technologies and solutions, has achieved a significant milestone by selling more than 700 REMUS uncrewed underwater vehicles (UUVs) to customers worldwide.

The REMUS UUV family offers a wide range of capabilities crucial for modern naval operations, including intelligence, surveillance, and reconnaissance (ISR), mine countermeasures, anti-submarine warfare, and electronic warfare. These autonomous systems can operate independently or be integrated with crewed platforms, such as Virginia-class nuclear submarines, to extend operational reach while minimizing detection risks and reducing personnel exposure.

With sales to over 30 countries, including 14 NATO members, the REMUS UUVs have proven their effectiveness and reliability in diverse operational environments. Over 90% of the vehicles delivered over the past 23 years remain operational, showcasing the platform’s durability and adaptability to evolving technologies.

Currently, HII is actively involved in manufacturing small uncrewed undersea vehicles (SUUVs) for the U.S. Navy’s Lionfish System program. This contract, valued at more than $347 million and potentially expanding to 200 vehicles over five years, is based on the REMUS 300 platform. The Lionfish System offers high portability, open architecture, and modular payload options, making it a versatile solution for a variety of missions.

REMUS UUVs have been utilized in various strategic operations, ranging from mine clearance in the Persian Gulf to NATO exercises in the North Sea and undersea surveillance in the Indo-Pacific region. Equipped with advanced sonar and sensor technologies, these systems enhance situational awareness and provide naval forces with a tactical advantage in challenging environments.

In mine countermeasures missions, REMUS plays a vital role in ensuring safe passage for naval and commercial vessels. The U.S. Navy has deployed REMUS in key waterways like the Persian Gulf, Baltic and Black Seas, while NATO allies have leveraged the platform in joint exercises across the Mediterranean, North Sea, and Arctic Circle.

Chris Kastner, President and CEO of HII, emphasized the company’s commitment to advancing undersea autonomy and meeting the evolving mission requirements of its customers. He stated, “HII’s investment in advanced undersea autonomy is yielding promising returns, most notably in demonstrating to our customers how this technology can be integrated to support their evolving and critical mission needs. From mine countermeasures to anti-submarine warfare, REMUS continues to safeguard strategic waterways and enhance maritime security for the U.S. and its allies. The platform’s longevity and adaptability reflect HII’s dedication to providing reliable, cutting-edge solutions for global partners.”
