Lockheed Martin to Acquire Ultra Maritime to Expand Undersea Warfare Portfolio

Lockheed Martin has signed a definitive agreement to acquire Ultra Maritime for $3.45 billion. With this acquisition, Lockheed Martin acquires a unique provider of advanced undersea warfare and anti-submarine warfare (ASW) systems to strengthen its military ecosystem, thus enabling it to enhance its capabilities in multiple domains in the United States and its allied navies around the world.

Ultra Maritime designs and develops highly-specialized and critical systems that counter subsurface naval threats. The technological suite includes advanced sonar, sonobuoy, torpedo defense countermeasure, surface radars, and autonomous marine sensing solutions. After the final closing of the deal, Ultra Maritime will become an integral part of Lockheed Martin’s Rotary and Mission Systems.

“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.”

Enhancing Allied ASW Capabilities Amid Surging Global Demand

The transaction takes place against a backdrop of increasing international demand for modern naval technologies and undersea defense platforms. By absorbing Ultra Maritime, Lockheed Martin secures a mature, export-ready array of maritime security assets that bypass long development lifecycles, immediately expanding its market presence across primary allied regions including Canada, the United Kingdom, and Australia.

“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’s international footprint and portfolio of exportable ASW products, such as its sonobuoys, towed sonar arrays and hull mounted sonar product lines, will complement and expand Lockheed Martin’s ability to offer sonar solutions across next-gen maritime platforms.
