Lockheed Martin signed a definitive agreement to acquire Ultra Maritime, a specialist in undersea and anti-submarine warfare, for $3.45 billion from private equity owner Advent.

The deal adds exportable sonobuoys, towed and hull-mounted sonar arrays, and torpedo defense systems that complement Lockheed's existing sonar work across naval platforms.

Ultra Maritime folds into Lockheed's Rotary and Mission Systems business, deepening allied undersea capabilities as demand for anti-submarine warfare accelerates.

AeroVironment received an $80.5 million task order, the first under a $500 million Army contract, to protect Air Force bases from small drones.

The layered defense for Air Force Global Strike Command pairs the AI-powered Titan-MS system with EO/IR cameras and radars against RF-controlled and autonomous threats.

The award follows drone incursions at Barksdale Air Force Base and expands the JIATF-401 task force's push to shield installations at home and abroad.

Thales agreed to buy French underwater-drone maker Exail at a €3.9 billion ($4.5 billion) enterprise value, offering €134 per share and topping a rival Safran bid.

Exail supplies mine-hunting drones and inertial navigation, with the addressable market for unmanned anti-submarine warfare forecast to grow eightfold by decade's end.

Separately, Italy's Fincantieri is spending €600 million on four undersea firms, signaling a wider European scramble for sub-surface dominance.

L3Harris ignited its solid fuel ramjet at full scale for the first time, sustaining thrust across the intended operating envelope under flight-like conditions.

Air-breathing ramjets draw atmospheric oxygen instead of carrying an oxidizer, cutting moving parts and cost while sustaining high-speed flight over longer ranges.

The test keeps propulsion on track for a future tactical missile demonstration aimed at affordable, longer-reach weapons for US and allied forces.

Britain's Urban-Air Port unveiled Pandora CADDS, a containerized system that deploys, recovers, and sustains drones using onboard AI and open-architecture command-and-control.

Three variants scale from a shoulder-carried P140 launching three FPV drones to a battalion-level P6240 that pre-positions live munitions for up to 30 days.

Compatible with Anduril's Lattice, the system cut launch times up to 80 percent in British Army trials, supporting distributed autonomous operations.

Saronic launched Mirage, a 15.8-meter autonomous surface vessel and its third platform, moving from initial design to launch in under a year.

Mirage exceeds 35 knots with a range beyond 2,500 nautical miles and a 3,500-pound payload, more than double its smaller Corsair.

The Austin facility can build hundreds of Mirage hulls annually as trials begin in Galveston for maritime domain awareness and security missions.

German drone maker Quantum Systems raised $1.2 billion in a Series D that more than doubled its valuation to $8 billion, Europe's largest deftech round.

Blackstone, Airbus, Noteus, and Advent co-led the round, with capital funding production capacity, supply chains, and its MOSAIC uncrewed-systems software.

Quantum's platforms flew over 19,000 missions in Ukraine last year, positioning the profitable firm as an emerging European "neo prime."
