Cambridge Aerospace has raised $300 million in Series C funding at a $3.4 billion valuation, the company announced today. The round was led by DFJ Growth with participation from Lux, Accel, Lakestar, Never Lift and other investors. The financing comes just four months after the company closed a $200 million Series B round in April 2026 that valued the startup at $1.3 billion, underscoring rapid growth.
Founded in 2024, Cambridge Aerospace develops air defence systems designed to counter modern drones. Its platform combines autonomous technology with low-cost interceptors to address the growing cost imbalance between inexpensive attack drones and traditional defensive missiles. The company’s Skyhammer interceptor is built to engage Shahed-type attack drones and has already secured orders from the UK Ministry of Defence as part of Britain’s Low-Cost Effectors and Autonomous Platforms programme.
In addition to Skyhammer, Cambridge Aerospace is developing Starhammer, a faster interceptor platform expected to enter service in 2027. Its technology portfolio also includes the Looking Glass radar system and the Nightstar solid rocket motor. Chief executive Steven Barrett said the new capital will help scale manufacturing and delivery to meet the pace of emerging threats and the needs of allied nations.
The company employs more than 250 people, with roughly two-thirds in engineering and technical roles. Its operations span the United Kingdom, Germany, Poland, Norway, Ukraine and Australia. The latest funding will expand production capabilities and support the development of new defensive technologies for international customers, according to the company.
DFJ Growth described the team as world-class and highlighted the company’s potential to help build infrastructure that European and NATO countries could use for modern air defence systems. The investment arrives as governments increase spending on counter-drone and air defence budgets, driven by concerns over autonomous and low-cost aerial systems. Cambridge Aerospace’s existing Ministry of Defence contracts provide a commercial foundation as it develops additional platforms.
The startup operates in a rapidly expanding European defence technology market where several companies have attracted significant funding. Unlike firms focused on offensive drones or battlefield software, Cambridge Aerospace concentrates on intercepting aerial threats and protecting critical assets. The round also reflects growing investor interest in physical defence infrastructure; DFJ Growth has previously backed major companies in aerospace, artificial intelligence and advanced engineering.
As demand for affordable, reliable counter-drone systems rises, the company’s ability to maintain a cost advantage while scaling production will be a key test. The funding underscores a broader shift in defence strategy toward cost-effective, autonomous air defence solutions for European and allied forces.
