Cambridge Aerospace Raises $300 Million and Reaches a Valuation of $3.4 Billion

Just a few months after its Series B round, the British defense technology company Cambridge Aerospace has closed a Series C funding round worth $300 million. This brings its valuation to $3.4 billion. The company plans to use the capital primarily to expand its production capacity, fulfill existing orders, and accelerate the development of new air defense systems.

DFJ Growth Leads Series C

The funding round is led by DFJ Growth. Other participants include Lux, Accel, Lakestar, Never Lift, Ora Global, and Elad Gil & Co.

The speed of the company’s growth is particularly noteworthy. As recently as April 2026, Cambridge Aerospace had closed a Series B round of $200 million at a valuation of $1.3 billion. Within just a few months, the company’s valuation has more than doubled.

Major Contracts from the British Ministry of Defense

Since the Series B round, Cambridge Aerospace has secured several contracts from the UK Ministry of Defense. These include the provision of cost-effective interception systems for the British armed forces. The company is also participating in the Low-Cost Effectors & Autonomous Platforms (LEAP) program, which was announced in July.

A key component of the portfolio is Skyhammer, a cost-effective interception system designed to counter drones and other airborne threats. The next product, Starhammer, is already in development and is scheduled to launch in 2027.

From Start-up to Billion-Dollar Company in Less Than Two Years

Cambridge Aerospace was founded less than two years ago and now employs more than 250 people. About two-thirds of them work in technical and engineering roles.

The company is led by CEO Professor Steven Barrett, CCO Chris Sylvan, and entrepreneur Junaid Hussain. In addition to the United Kingdom, Cambridge Aerospace already has a presence in Germany, Poland, Norway, Ukraine, and Australia.

The additional $300 million will now be used primarily to significantly ramp up production. At the same time, the company plans to further expand its workforce and develop new technologies for air defense.

Germany Prefers to Invest in Frigates and Tanks

This is particularly interesting when one considers that, at the same time, accusations are being leveled against German Defense Minister Boris Pistorius that he is investing 700 billion primarily in outdated military technology such as tanks and frigates. Yet there is currently an opportunity to interview volunteer combat medics about their frontline experiences in Ukraine. The discussion about what a simple fiber-optic drone costing around 1,500 euros can accomplish compared to a 25,000,000 LEO must finally take place in Germany as well.
