Shield AI & Echodyne

Shield AI has agreed to acquire radar maker Echodyne in a transaction valued at $5.3 billion and is raising $2.5 billion to support the deal, the San Diego defense technology company said in an announcement. Of that value, $4.8 billion will be paid and issued at closing, and up to $500 million more hinges on Echodyne meeting performance targets that were not disclosed. The deal is expected to close in early 2027, pending regulatory approvals.

The financing pairs a $1 billion Series H at a $28.8 billion post-money valuation with a $1 billion structured equity investment from funds managed by Blackstone and $500 million in debt arranged by JPMorgan Chase. Disruptive and Innovation X Capital co-led the Series H, joined by Advent, Snowpoint Ventures, Apandion and JPMorganChase’s Security and Resiliency Initiative, and Shield AI said that money will go mainly toward the purchase.

Axon & Skydio

Axon will invest about $1.2 billion more in Skydio through a mix of cash and Axon stock, adding roughly 20% to its fully diluted stake at a $5.2 billion pre-money valuation, according to the Scottsdale, Arizona company. The money combines new capital for Skydio with shares bought from existing holders, though the split between the two was undisclosed and final terms are still being set. Axon (Nasdaq: AXON) also becomes Skydio’s exclusive public-safety distributor in the U.S. and Canada.

Skydio, which supplies every branch of the U.S. military and the armed forces of 32 allied nations, serves more than 1,500 public-safety customers and expects about $1 billion in bookings this fiscal year, according to the release. Axon put the market for drones sent out as first responders at about $13 billion in the U.S. and Canada. The transactions are expected to close over the fourth quarter of 2026 and the first quarter of 2027.

Alta Ares

Paris-based Alta Ares said it won six of the 16 lots in NATO’s new counter-drone framework contract, more than any other supplier, according to a company announcement. The NATO Communications and Information Agency named Alta Ares, Axon, Northrop Grumman, OSL UK and Quantum Systems as the five selected companies and said allies can now buy their systems straight from a NATO catalog without running a new tender. Contract values were undisclosed.

Alta Ares said its lots cover area defense and border protection and that it is the only supplier picked for area defense in static, transportable and on-the-move setups. The agency said the framework contracts run 18 months from signature with an option to extend, and NATO set aside €3.1 million to fund more testing. For large orders, Alta Ares plans to set up production in the customer’s country.

Xtend

Xtend Robotics said its Asia-Pacific subsidiary, Performance Rotors, received a purchase order worth about $8.3 million from a defense customer in the region, according to a Business Wire release. The customer, its country and the number of systems were undisclosed. The order covers small, collision-tolerant drones built for rapid deployment in dense urban areas, along with ground control stations, plus a first year of software updates for every system through the company’s XOS operating system. The Tampa company builds the drones at Performance Rotors’ plants in its regional manufacturing network. Xtend said the order comes on top of its most recently reported AI Robotics backlog of about $84 million.

Saga Defence Engineering

India’s Sagar Defence Engineering, which makes unmanned and autonomous defense systems, raised ₹300 crore (about $32 million) in a pre-IPO round that values it at ₹20,000 crore (about $2.1 billion) before the new money, India Sentinels reported. The investors were undisclosed and described only as domestic institutions. Founder Nikunj Parashar told the outlet the company has received the securities regulator’s final observations on its IPO filing. The company said the money will go toward research and development, autonomous systems, advanced manufacturing and homegrown technology.

Elroy Air

Elroy Air’s merger with special purpose acquisition company Inflection Point Acquisition Corp. VII is headed to a shareholder vote later this month after the SEC declared the deal’s registration statement effective, according to a regulatory filing. Elroy Air said it has about $175 million in committed financing. That includes $75 million already funded ahead of the PIPE, with Lockheed Martin Ventures and Inflection Point taking part, and a $100 million private share sale expected to fund at closing whose investors were not named.

The San Francisco company plans to use the money to speed production of Chaparral, a hybrid-electric autonomous cargo drone that takes off vertically and, according to Elroy Air, can carry more than 500 pounds up to 450 miles. Kratos Defense & Security Solutions will build it in Sacramento, California, with first production aircraft planned for late 2026. Elroy Air pointed to a U.S. Army contract worth up to $46 million and 15 early delivery reservations from Bristow Group, though the filing cautioned that the reservations are uncommitted and Army contract options may not be exercised. The deal is expected to close in December, and the combined company plans to trade on Nasdaq under the ticker ELRY, replacing Inflection Point (Nasdaq: IPXG).

Oshkosh Defense & Grid Aero

Oshkosh Defense will help Silicon Valley startup Grid Aero ready its Lifter autonomous cargo aircraft for production and eventually build it at scale in Wisconsin, according to the companies. Oshkosh, a unit of Oshkosh Corp., will take on design for manufacturing, production planning and supply chain work. Grid Aero CEO Arthur Dubois described Lifter as a rugged, piston-powered aircraft made from common materials that borrows as much from military trucks as from traditional aircraft. The companies are aiming it at the Department of War’s call for low-cost Group 4 and 5 drones it can buy in quantity. Financial terms were undisclosed. Early work centers on production engineering and customer outreach, with the goal of showing production-ready aircraft to defense buyers.

Renault Group & John Cockerill

Renault Group and Belgian defense and industrial group John Cockerill unveiled Forefront Concept, a remotely operated electric ground vehicle for military and civilian missions, according to a joint announcement. The four-wheel-drive, four-wheel-steer platform runs on two electric motors and targets a range of about 400 kilometers (about 250 miles), which a range extender can stretch, along with a payload of up to one metric ton.

Renault designed the platform around proven automotive parts to hold down costs for large-scale production, while John Cockerill built the remote-operation and autonomy software, which it eventually wants to run the vehicle fully on its own. The companies listed logistics, reconnaissance, counter-drone work, fire support and evacuation among military uses. Developed with input from the French armed forces, the concept will go through exercises and trials in the coming weeks. Price, volumes and orders were undisclosed.

Alpha Unmanned Systems

Madrid-based Alpha Unmanned Systems, which builds small fuel-powered unmanned tactical helicopters, closed €4 million in financing backed by Spain’s export credit agency Cesce with Banco Santander, Bankinter and BBVA taking part, DroneLife reported. The money will fund a new Madrid production plant and hiring. Alpha counts customers in 14 countries, including the U.S. Department of Defense and the Hellenic Navy.
