Cambridge Aerospace funding 2026 puts valuation at $3.4bn

Cambridge Aerospace funding 2026 has reached $300 million: Sifted reported on August 10 that the British air-defence startup completed a Series C at a $3.4 billion valuation. DFJ Growth led the reported round, with Lux Capital, Accel, Lakestar and Elad Gil participating, according to Sifted.

The financing is a sharp step up in capital for a company Sifted described as two years old, and follows its reported $200 million Series B only a few months earlier. Cambridge Aerospace says the fresh money will expand its manufacturing capabilities, support delivery on contracts and continue investment in its interceptor products.

The available reporting does not provide revenue, a share price, or the round's pre-money valuation. Sifted also did not specify whether its $3.4 billion figure was pre- or post-money. Resilience Media, reporting in July before an announced close, described the same $3.4 billion valuation as post-money.

Who invested in Cambridge Aerospace's Series C?

Sifted named US investment firm DFJ Growth as lead investor and listed Lux Capital, Accel, Lakestar and Elad Gil as participants. The report did not disclose how much each investor committed, ownership stakes or board arrangements.

For a venture-backed defence company, the valuation is a negotiated financing price rather than an operating metric. It sets the price of new shares and the dilution borne by existing holders, as explained in Venture Post's guide to startup valuation.

What does Cambridge Aerospace build?

Cambridge Aerospace's main product, Skyhammer, is designed to intercept drones and low-speed missiles, according to Sifted. The company also plans to bring a rocket-powered system called Starhammer to market in 2027. That timetable is a company target, not a confirmed launch date.

The commercial backdrop is beginning to take shape, though the available reporting contains limited contract detail. Sifted said the UK government announced a multi-million-pound April contract to supply the company's interceptor missiles to UK armed forces and Gulf partners. It also reported that the government said Skyhammer missiles were successfully tested in Jordan in May.

Why did earlier reports cite a $3.5bn valuation?

The difference reflects the deal's progression rather than necessarily a direct disagreement. In June, Bloomberg reported that Cambridge Aerospace was discussing a raise of about $300 million at roughly a $3.5 billion valuation, citing people familiar with the matter. Bloomberg said DFJ Growth was in talks to lead and that the terms had not been finalized.

Resilience Media then reported in July, citing sources close to the company, that it had raised $300 million at a $3.4 billion post-money valuation while characterizing an announcement as imminent. Sifted's August account presents the $300 million Series C and $3.4 billion valuation as completed. Manufacturing expansion, contract delivery and progress on the product schedule will be important indicators of whether the company can support that valuation.
