Lockheed Martin reported to be in talks for Ultra Maritime, a deal that could reach about $3.5 billion

Lockheed Martin (NYSE: LMT) is emerging as a frontrunner in a potential transaction to buy Ultra Maritime in a deal reported to be worth roughly $3.5 billion, according to market reporting. The talks, described as ongoing, have not yet produced a formally agreed acquisition, leaving timing and terms uncertain.

The interest centers on Ultra Maritime, a naval technology business tied to undersea defense and anti-submarine warfare. Reporting characterizes Ultra Maritime as producing undersea defense systems that include buoys designed to detect torpedoes and submarines, with use by the U.S. Navy and the UK’s Royal Navy. Ultra Maritime’s work also ties into broader efforts to combine sensors and autonomous undersea platforms for next-generation tracking and response.

Several media summaries tied to the report say the auction or competitive process includes other U.S. and European bidders, suggesting the outcome is not locked in. One account also indicated the deal could potentially be announced as early as next week, but that would depend on whether negotiations reach final agreement.

Beyond the headline price, the deal narrative is framed around Ultra Maritime’s performance and scale. One research summary says Ultra Maritime’s revenue is on track to reach about $784 million in 2026, compared with roughly $494 million in 2023, after Advent invested about $170 million in product development over the past three years. It also describes Ultra Maritime as employing around 2,000 people across the “Five Eyes” intelligence-sharing alliance, though those details have not been confirmed by an Ultra Maritime or Lockheed Martin announcement in the available material.

Technology partnerships are also part of the reported picture. Reporting says Ultra Maritime worked with Anduril Industries to develop next-generation anti-submarine technology that combines autonomous subsea vehicles with Ultra Maritime’s sensors. If true, Lockheed’s potential purchase would not only add products, but also bring in partnerships and systems integration experience tied to unmanned undersea operations.

For Lockheed Martin, an acquisition of this kind would align with a push to expand undersea warfare offerings. Undersea defense is often described by primes as a strategic growth area because it intersects with deterrence, intelligence, surveillance, and rapid operational response against submarine threats. A reported focus on anti-submarine capabilities also reflects customer priorities across NATO-aligned naval forces, where sensing and tracking remain central bottlenecks for undersea operations.

Still, important details are not clear from the market reporting. There is no disclosure in the available material about the structure of the potential transaction, including whether it is an all-cash deal, how regulatory or national security reviews might be handled, or what specific assets and business lines Ultra Maritime would include. Lockheed Martin has not, in the provided information, confirmed that talks are underway or that an offer has been made, nor has any official company filing or press release been cited that sets a timetable or price breakdown.

What to watch next is whether Lockheed Martin, Ultra Maritime, or Advent confirms discussions through a filing or official statement, and whether any competing bidders submit higher offers. The next milestone would likely be proof that talks have moved from reporting to contract-level certainty, such as a binding purchase agreement, along with clearer disclosure on valuation, closing conditions, and how the combined capabilities would be integrated into Lockheed’s undersea portfolio.
