- Lockheed Martin announced a definitive deal on July 6 to acquire Ultra Maritime, a global undersea and anti-submarine warfare specialist, from private-equity owner Advent International for $3.45 billion, adding advanced sonar, sonobuoy and autonomous sensing capabilities to its portfolio.
- The acquisition is the largest US defense M&A move of the week and comes as the Pentagon accelerates spending on submarine and undersea sensing capabilities to counter growing Russian and Chinese sub activity.
- Ultra Maritime will be folded into Lockheed's Rotary and Mission Systems business; the deal is expected to close in H2 2026 subject to regulatory approvals (Bloomberg).
