BETHESDA, MD, July 7, 2026 – Lockheed Martin has signed an agreement to acquire Ultra Maritime for $3.45 billion, adding undersea and anti-submarine warfare systems to its Rotary and Mission Systems business.
Ultra Maritime’s exportable anti-submarine warfare products include sonobuoys, towed sonar arrays and hull-mounted sonar product lines. Lockheed Martin said the acquisition will expand its sonar offerings for U.S. and allied customers.
“Undersea superiority belongs to those who move fastest and work together best,” said Stephanie C. Hill, president of Lockheed Martin Rotary and Mission Systems. “By joining forces with Ultra Maritime, we’re accelerating our commitment to deliver the most advanced undersea and anti-submarine warfare capabilities to our U.S. and allied partners across the globe.”
“When we invested in Ultra Maritime in 2022, we saw a business with mission-critical technology and a vital role in protecting allied nations from undersea threats, but one that had been underinvested and was not yet fully delivering for its customers,” said Shonnel Malani, managing partner at Advent and chair of the board at Ultra Electronics. “Over the past four years, we have changed that. Ultra Maritime is now a stronger, more innovative partner to allied navies, with improved execution, greater industrial capacity and next-generation autonomous solutions that position it well for future warfare.”
Ultra Maritime will become part of Lockheed Martin’s Rotary and Mission Systems business area after the transaction closes.
