After the closing of the deal, announced on Monday, Ultra Maritime will become a part of Lockheed's rotary and mission systems, which reported revenue of $17. 3 billion in 2025 and employs 35,000 people worldwide. Sustained conflicts in Ukraine and the Middle East, and US President Donald Trump's $1. 5 trillion defence budget request for 2027 are driving up demand for weapons and military technology, pushing defence contractors to expand their capabilities. Ultra Maritime, specialising in anti-submarine warfare and undersea defence technologies, is a part of Cobham Ultra — created after Advent acquired British aerospace company Cobham in 2020 and then combined it with Ultra Electronics following its 2022 takeover. Lockheed said Ultra Maritime's international presence and a portfolio of exportable anti-submarine warfare technologies, including naval sonar sensing systems, will complement and expand its existing sonar solutions. Earlier this year, Ultra Maritime received a development contract from the US Navy for its underwater acoustic decoy, designed to protect ships or submarines from torpedoes. In 2025, Ultra Maritime announced a partnership with Anduril Industries to advance autonomous ocean sensing, and General Atomics Aeronautical Systems to develop unmanned airborne anti-submarine warfare capabilities.
