Ultra Maritime is being sold by private equity firm Advent International, which acquired the business as part of its 2022 takeover of Ultra Electronics. Since then, Advent has invested approximately $170 million to expand manufacturing capacity, accelerate product development, and strengthen the company's position in next-generation undersea warfare technologies. 

According to Ultra Maritime CEO Carlo Zaffanella, those investments enabled the company to scale independent sonobuoy production, modernize its manufacturing operations, and advance a new generation of modular sonar and autonomous acoustic sensing systems. The company has also reinforced its leadership in torpedo technologies, towed and hull-mounted sonar systems, radar solutions, and torpedo countermeasures, making it an increasingly valuable strategic asset in the global maritime defense market. 

Ultra Maritime is a UK-based defense technology company specializing in advanced undersea and anti-submarine warfare solutions for allied naval forces. Its portfolio includes sonar systems, sonobuoys, torpedo defense technologies, radar solutions, autonomous maritime sensing platforms, underwater sensors, shipboard power and propulsion integration, survivability solutions, and specialized engineering services for both surface and subsurface vessels. The company's technologies are widely deployed by the U.S. military and allied nations, making it a key supplier of mission-critical naval systems. 

According to Lockheed Martin, the acquisition supports its strategy to expand capabilities across the full maritime technology stack—from sensors and electronic warfare to integrated combat systems and autonomous platforms. By combining Ultra Maritime's expertise in underwater sensing and anti-submarine warfare with Lockheed Martin's strengths in command-and-control systems, missile platforms, naval combat systems, and autonomous technologies, the company aims to deliver more integrated solutions for modern naval operations. 

This latest transaction also reflects growing demand for next-generation maritime defense technologies. As geopolitical tensions continue to rise and governments across the Indo-Pacific, Europe, and other strategic regions increase defense spending, investments in undersea surveillance, anti-submarine warfare, and autonomous naval systems have become a priority for many allied nations. 

Once the transaction closes, Ultra Maritime will be integrated into Lockheed Martin's Rotary and Mission Systems business, supporting its naval programs through tighter hardware and software integration and faster delivery of ship modernization initiatives. The combination is expected to enhance Lockheed Martin's ability to develop end-to-end maritime defense solutions while expanding its presence in one of the defense industry's fastest-growing segments. 

The transaction remains subject to customary regulatory approvals and other closing conditions. Citigroup served as financial adviser to Lockheed Martin, while Guggenheim Partners and JPMorgan Chase advised Advent International on the sale. If completed as announced, the deal will represent another significant step in the ongoing consolidation of the global defense industry while reinforcing Lockheed Martin's leadership across air, land, sea, space, and cyber defense technologies.
