Ultra Maritime develops and delivers mission-critical systems for allied naval forces. Its portfolio includes sonar technologies, sonobuoys, torpedo defense systems, radar solutions and autonomous maritime sensing platforms.
The acquisition is intended to reinforce Lockheed Martin’s commitment to domain expertise in anti-submarine warfare. The company said Ultra Maritime’s capabilities would support the delivery of advanced undersea and anti-submarine warfare systems to U.S. and allied partners.
“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.”
Ultra Maritime’s international footprint and exportable anti-submarine warfare products are expected to complement Lockheed Martin’s maritime portfolio. The company cited Ultra Maritime’s sonobuoys, towed sonar arrays and hull mounted sonar product lines as areas that will expand Lockheed Martin’s ability to offer sonar solutions across next-generation maritime platforms.
“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.”
Lockheed Martin said the acquisition would strengthen its ability to support allied naval forces in the undersea domain. The deal also adds technologies and platforms used for detecting, sensing and defending against maritime threats.
Upon closing, the Ultra Maritime team will become part of Lockheed Martin’s Rotary and Mission Systems business area. Lockheed Martin did not provide additional closing details in the announcement.
