What's happening

Shield AI, which builds AI-piloted aircraft, has agreed to acquire Kirkland, Washington-based radar maker Echodyne for up to $5.3 billion. The company is raising $2.5 billion to help fund the deal, including $1 billion in new funding at a $28.8 billion valuation.

Why it matters

Shield AI says successful defense tech companies will need products that "sense, think, and act." Its Hivemind autonomy software handles the thinking, while its V-BAT drone and X-BAT jet handle the acting. Echodyne becomes the cornerstone of the sensing piece.

The Seattle push

In September, Shield AI unveiled plans to build its X-BAT fighter jet at a factory south of Seattle. The company projects it will employ about 4,000 people in the region by the early 2030s. Co-founder Brandon Tseng cited the region's density of engineering and manufacturing talent as the main reason for choosing the Pacific Northwest.

The Echodyne side

Echodyne has about 400 employees and opened a $40 million radar factory in Woodinville in July. Co-founder and CEO Eben Frankenberg will stay in his role, reporting to Shield AI CEO Gary Steele. The combined company will have about 2,700 employees, and the deal is expected to close in early 2027 pending regulatory approval.
