British aerospace technology company Greenjets raises €35 million Series A with NATO backing

Greenjets, a London-based aerospace technology company developing propulsion systems, aircraft platforms and launch technologies for the next generation of aviation, today announced a €35 million ($40 million) Series A funding round.

The round was led by Blossom Capital, with participation from the NATO Innovation Fund (NIF), the National Security Strategic Investment Fund (NSSIF), and existing investors including Tanglin Ventures, NSFO Family Office and others.

Anmol Manohar and Dr. Guido Monterzino, the CEO and CTO of Greenjets, said in a joint statement, “When we founded Greenjets, our ambition was to develop the technologies that would shape the future of aviation. 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. We believe building affordable defensive capability is a necessary response to today’s realities, and a natural extension of our mission to advance aviation.”

Founded in 2022 by Manohar and Dr Monterzino, Greenjets claims that its patented engine technology increases aircraft safety and reduces the certification burden. The company has developed proprietary propulsion architectures spanning electric ducted fans through to geared turbofan engines.

Combined with advanced aircraft integration and low-cost manufacturing, these technologies enable aircraft that are quieter, faster, more efficient and better suited to the demands of modern aerospace. 

According to the company, recent conflicts have demonstrated how rapidly aviation is changing, and how urgently Europe needs affordable technologies that can protect people, critical infrastructure and national resilience.

Greenjets claims that its technologies are helping address that challenge, applying the same advances in propulsion, aircraft integration and manufacturing that underpin a wider aerospace portfolio. Its integrated portfolio spans propulsion systems, aircraft platforms and launch technologies, all built on a common technology stack. As per the company, this enables rapid iteration, production at scale and deployment across multiple aerospace applications.

NIF stated, “Drones have become the defining weapon of modern conflict. Russia produced over 50,000 Shahed-class attack drones in 2025, up from 11,000 in 2024. As these are getting faster, the predominant challenges of intercepting them become not only economic but also capability driven.

“Newer Shahed drone variants are reaching speeds of 500 km/h. At those speeds, propeller-based interceptors struggle to catch them. Turbojets can, but they take up to two minutes to spool up and have constrained supply chains. Greenjets provides the underlying engines and airframes to close this gap.”

The company is under contract across multiple UK and international programmes, with technologies progressing towards demonstration trials with the UK MOD and partners this year. 

Greenjets has expanded its UK facilities from 12,000 to nearly 70,000 square feet and is on track to grow from 160 to more than 250 people, supporting the transition from development to production.

 Patrick Schneider-Sikorsky, Partner at NIF, commented, “The speed at which the defence and security drone industry is evolving means that propulsion is the constraint that determines whether an interceptor can close the gap on a 500 km/h target or vice versa. Greenjets is addressing this at the engine and airframe level, meaningfully improving the performance of UAS and CUAS companies, without them having to solve propulsion independently. This is exactly the kind of Allied supply-chain technology we were set up to back.”

The company plans to use this funding to accelerate its transition from development to production, supporting the delivery of thousands of systems over the next 12 months. Alongside scaling production, the investment will accelerate development across its propulsion, aircraft and launch technology portfolio, while supporting continued expansion with international partners and customers. 

Greenjets was recently named one of three companies selected by the UK MOD under the Low-Cost Air Defence Effectors (LCADE) programme to develop a British low-cost drone interceptor. LCADE is delivered by the National Armaments Director Group as part of LEAP, a five-nation European effort spanning the UK, Poland, France, Italy and Germany, with the UK becoming the first partner nation to put suppliers on contract. Greenjets’ interceptor moves into demonstration trials later this year.  

Greenjets, based in the UK with operations in Germany, is increasing its presence in India, the Middle East, and the United States.
