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 U.S. President Donald Trump's $1.5 trillion defense budget request for 2027 are driving up demand for weapons and military technology, pushing defense contractors to expand their capabilities.

Ultra is owned by private equity firm Advent International, and specialises in anti-submarine technology.

The $3.45 billion deal will fold Ultra Maritime into Lockheed’s rotary and mission systems business, strengthening its naval defense portfolio.
