UK taps defense startup Cambridge Aerospace for interceptors
The UK has signed a multimillion-pound contract with Cambridge Aerospace, a defense startup formed in late 2024, to supply hundreds of Skyhammer interceptors within weeks, as Western militaries seek cheaper ways to counter drones and low-cost missiles.
Defense Secretary John Healey announced the deal in London, and CEO Steven Barrett said former defense secretary Grant Shapps, the startup’s chair, recused himself from any contracts and decisions involving the UK government.
Barrett said the interceptor would cost in the low tens of thousands and fly at around 700 kmh, but Cambridge Aerospace has not publicly demonstrated the system and did not disclose a precise price.

🧠 Food for thought
Implications, context, and why it matters.
A venture-backed startup is delivering defense hardware at software speed
- Cambridge Aerospace built its Skyhammer interceptor from concept to initial flight testing in six weeks in early 2025. Weekly test cycles helped fine-tune the system 1.
- Pricing aims to match the US$20,000–US$50,000 Shahed-style drones it targets. Shahed-style drones are low-cost one-way attack drones widely used by Russia in Ukraine. Legacy missiles like the ASRAAM, or Advanced Short Range Air-to-Air Missile, cost about 200,000 pounds (US$268,000) each 2.
- Backers have put in more than US$130 million, including Spark Capital and Ukraine’s D3 fund, an investment fund backed by former Google CEO Eric Schmidt 3.
The economics of air defense are shifting toward “affordable mass”
- The contract ties to a move toward “affordable mass”. The idea uses large numbers of low-cost interceptors against saturation drone attacks, shaped by lessons from the war in Ukraine 4, 5.
- The deal moves forward while the UK’s broader Defence Investment Plan stays unpublished. It also signals quicker procurement for counter-UAS solutions. Counter-UAS refers to systems designed to stop unmanned aircraft systems, or drones, based on the UK’s experience supporting Ukraine 2.
- Lower unit costs make it more realistic to defend civilian infrastructure and large events like the Olympics from drone threats. It also addresses a homeland security vulnerability 6.
- Plans include systems for UK forces plus systems for Gulf partners, based on the UK Defence Secretary’s announcement 7.
