MESA radar maker Echodyne to join Shield in $5.3bn deal

Shield has agreed to buy Echodyne, the Washington-based maker of MESA radars for counter-UAS and airspace sensing, for $5.3bn. Echodyne's radars stay available as standalone products, and the deal adds production capacity for the sensor line.

The acquisition is backed by $2.5bn in new financing: a $1bn Series H round, $1bn from Blackstone funds as structured equity, and $500m in debt via JPMorgan Chase Bank. Post-investment, the Series H values Shield at $28.8bn. Echodyne shareholders receive $4.8bn at closing in cash and shares, and a further $500m depends on performance targets. Closing is expected in early 2027, pending regulatory approvals and customary conditions.

Echodyne will join Shield’s Mission Systems business. CEO Eben Frankenberg will report to Shield CEO Gary Steele and remains responsible for products, manufacturing, partners and customers. Echodyne’s solid-state radars use its patented Metamaterials Electronically Scanned Array technology, and the product line stays on sale as standalone systems.

Radar is a new sensing line for Shield, whose existing businesses cover Hivemind autonomy software, Aechelon simulators and the V-BAT and X-BAT platforms. Echodyne has opened an 86,350ft2 facility in Washington after a $40m investment, expected to produce about 30,000 radars annually. Both companies expect triple-digit revenue growth this financial year, without giving revenue figures.

Why it matters

Echodyne’s radars detect and track drones in counter-UAS chains, and its customers in defense, government and commercial markets span more than 40 countries. The radars connect to high-power microwave systems, high-energy lasers and remote weapon stations, and they cue interceptors against incoming drones. A September contract from Joint Interagency Task Force 401, capped at $250m, covers counter-drone radar for US and allied forces.

Three Echodyne radars are listed in the directory. EchoShield is the medium-range 4D radar and is commercially exportable under ECCN 6A008.e. EchoGuard is the short-range unit, networked through EchoWare. EchoFlight is the airborne radar for UAS, weighing under 1 kg and drawing under 50 W.

The new site adds output for radar buyers; closing awaits regulatory approval. Frankenberg says autonomous systems can act only on what they sense, and that joining Shield gives Echodyne more scale to serve its customers.
