Shield AI to Buy Echodyne for $5.3B and Raise $2.5B at $28.8B Value

Shield, the defence technology company widely known as Shield AI, said on 5 November 2026 that it will buy radar maker Echodyne in a deal worth up to $5.3 billion. To pay for it, Shield is raising $2.5 billion in new equity and debt, including a Series H round that values the company at $28.8 billion. The move gives Shield its own sensor business at a time when demand for counter-drone systems is rising fast.

What happened?

Shield announced that it has agreed to acquire Echodyne Corp., a radar company based in Kirkland, Washington. Under the terms, Shield will pay and issue $4.8 billion when the deal closes. Up to $500 million more is payable if Echodyne meets performance targets agreed between the two companies.

At the same time, Shield is putting together a $2.5 billion financing package, made up of three parts:

• $1 billion Series H at a $28.8 billion post-money valuation, co-led by Disruptive and Innovation X Capital. Advent, the Strategic Investment Group of JPMorganChase’s Security and Resiliency Initiative, Snowpoint Ventures, Apandion and Center15 Capital also took part.
• $1 billion in structured equity from funds managed by Blackstone.
• $500 million in debt led by JPMorgan Chase Bank as sole arranger.

Shield said most of the Series H money will go towards the acquisition. The Next Web reported that the new funding only goes ahead if the deal closes.

Crunchbase News ranked Shield’s raise as the largest startup financing of the week ending 6 November, ahead of drone delivery company Zipline, which we covered in Zipline’s $1.5 billion raise.

Who is Echodyne?

Echodyne makes compact, solid-state radars that spot and track drones and other airborne objects. According to Shield, the radars are built into hundreds of counter-drone and security systems used in more than 40 countries. Uses range from military systems that guide drone interceptors to civilian setups that watch the airspace around airports and stadiums.

The company has been scaling up. In September, Joint Interagency Task Force 401 awarded Echodyne a contract with a ceiling of $250 million to supply counter-drone radar to US and allied forces. Echodyne has also opened an 86,350-square-foot factory in Washington state, a $40 million investment that can produce about 30,000 radars a year.

Echodyne CEO Eben Frankenberg said Shield agrees that autonomous systems “can only act on what they can sense.”

What changes for Shield?

Shield, founded in 2015, is best known for Hivemind, its AI software that flies military aircraft without a pilot, the V-BAT surveillance drone and the X-BAT, an AI-piloted fighter jet that takes off vertically. It also owns Aechelon, a simulation company whose acquisition it announced in March 2026.

Echodyne will become part of Shield’s Mission Systems business, which will now cover radar design and manufacturing alongside Shield’s autonomy software and aircraft. Echodyne’s team will stay in place, and its radars will still be sold as standalone products. Frankenberg will report directly to Shield CEO Gary Steele and remain in charge of Echodyne’s products, factories and customer relationships.

Both companies said they expect triple-digit revenue growth in the current fiscal year. Neither shared revenue figures.

The Next Web, citing Bloomberg, described Echodyne as Shield’s first move into “dual-use” hardware that can also be sold outside the military. Until now, all of Shield’s end users have been governments. Steele pointed to public safety as a new market, saying that every single thing “is going to need protection from drones.”

Why it matters

The deal shows how much money is flowing into defence technology startups:

• Valuation jump: Bloomberg reported that the $28.8 billion valuation is more than double Shield’s valuation in March 2026.
• Hiring: Shield’s headcount has more than doubled in a year to nearly 2,300, according to the same report.
• Investor appetite: Disruptive, one of the Series H leads, closed a $10 billion fund in October to back late-stage AI and defence companies.
• Competition: Rival Anduril is valued at close to $90 billion, The Next Web noted.

Owning a radar maker lets Shield control a key part of the counter-drone chain: detecting a threat before an autonomous system can respond to it. It also adds a product line with civilian customers, which can spread Shield’s risk beyond defence budgets.

The funding fits a wider pattern of very large private rounds for AI-heavy companies this autumn, such as Applied Compute’s $350 million raise.

What happens next?

Shield expects the acquisition to close in early 2027. It still needs regulatory approvals and must meet other customary closing conditions. Covington & Burling is advising Shield on regulatory and business diligence, with J.P. Morgan Securities as its exclusive financial adviser. Morgan Stanley and Robert W. Baird are advising Echodyne.

Steele also said the X-BAT fighter jet will make its first flight before the end of 2026, The Next Web reported. Shield chose Washington state as the production home for X-BAT in September, close to Echodyne’s base in Kirkland.
