British aerospace technology company Greenjets has closed a $40 million Series A funding round led by Blossom Capital, with participation from the NATO Innovation Fund, the National Security Strategic Investment Fund and existing investors including Tanglin Ventures and NSFO Family Office. The London-based company is scaling its ducted-fan propulsion systems and pushing to become what its founders call "the UK's next aerospace prime."
From ducted fans to drone killers
Greenjets designs propulsion systems, aircraft platforms and launch technologies built on a single technology stack. Its ducted fans claim up to 45% less power for a given thrust, flight speeds of up to 125 m/s and noise reduction of up to 93% versus open-bladed propellers of the same diameter. The announcement follows Greenjets' selection by the UK Ministry of Defence under the Low-Cost Air Defence Effectors (LCADE) programme as one of three companies developing a British drone interceptor, with demonstration trials due later in 2026.
"When we founded Greenjets, our ambition was to develop the technologies that would shape the future of aviation," said co-founders Anmol Manohar (CEO) and Dr Guido Monterzino (CTO). "The conflict in Ukraine has reinforced just how important those same technologies are in protecting lives, strengthening Europe's resilience and enabling the future of flight."
Scaling for LEAP and sovereign aerospace
The Series A will accelerate the shift from development to production, supporting delivery of thousands of systems over the next 12 months, and will fund further work across propulsion, aircraft and launch platforms. Greenjets has expanded from 12,000 to nearly 70,000 square feet of UK facilities in the past year and is on track to grow from 160 to more than 250 staff. LCADE is delivered as part of LEAP, a five-nation European effort spanning the UK, Poland, France, Italy and Germany.
Backdrop: a European counter-drone spending wave
The raise plugs Greenjets into a fast-growing European counter-drone budget: the UK Defence Investment Plan alone commits more than £750 million to short-range counter-drone protection and more than £5 billion to drones and autonomous systems. The Greenjets round also follows fresh capital for adjacent players including Skapion's $36M seed for counter-swarm defense, Quantum Systems' $1.2B Series D and Agon's $30M seed for synthetic training.
