A trio of major acquisitions announced on Monday underscored the global defense industry's intensifying focus on undersea warfare and maritime drone technology, with deals collectively valued at more than $8 billion reshaping the sector in a single day.

Lockheed Martin Moves on Ultra Maritime

Lockheed Martin confirmed Monday that it will acquire Ultra Maritime, a naval defense specialist owned by private-equity firm Advent International, for $3.45 billion. The deal, first reported by the Financial Times last week when Lockheed emerged as the frontrunner in a competitive auction, gives the U.S. defense giant expanded capabilities in anti-submarine warfare and undersea sensing technologies. CNBC reported that Guggenheim and JPMorgan advised on the sell side of the transaction.cnbc+1

Thales Targets French Maritime Drone Maker Exail

Separately, Thales announced it has agreed to acquire the Gorgé family's 35.51% controlling stake in Exail Technologies, a French company specializing in maritime robotics and navigation systems, at a price of €134 per share. The deal implies an enterprise value of approximately €3.9 billion ($4.5 billion) and represents a 44% premium to Exail's undisturbed share price on June 25, before rumors of a bid surfaced. Thales intends to launch a mandatory tender offer for all remaining Exail shares once the initial stake acquisition closes, which is expected by the third quarter of 2027, with full ownership anticipated by early 2028.bloomberg+3

Exail reported €479 million in revenue in 2025, and Thales said the acquisition would bolster its capabilities in underwater warfare and maritime autonomy.rttnews

Fincantieri Expands Underwater Footprint

Italian shipbuilder Fincantieri also announced Monday that it will acquire majority stakes in four Italian subsea technology companies — Next Geosolutions, WSense, Graal Tech, and Defcomm — for an initial investment of approximately €600 million ($685 million). The firms will be integrated into Fincantieri's Underwater technological hub, building on its 2025 acquisition of Leonardo's underwater armaments division. Fincantieri shares rose as much as 14% on the news.globalbankingandfinance+1

The three deals reflect a broader race among Western defense contractors to secure capabilities in autonomous maritime systems and undersea surveillance as navies worldwide expand their submarine fleets and underwater infrastructure.
