Space startup Greenjets raises £29.9m led by Blossom Capital and NATO Innovation Fund
This article covers Greenjets, a British space startup, which has raised £29.9m in a series A funding round and moved into demonstration trials on a UK Ministry of Defence Low-Cost Air Defence Effectors (LCADE) contract. The funding supports acceleration of propulsion, aircraft and launch technology development and production, targeting defence programmes and UK sovereign aerospace supply chains.
Greenjets, a British space startup, has raised £29.9m in a series A funding round to accelerate the development and production of propulsion systems, aircraft platforms and launch technologies. The raise comes as Greenjets moves into demonstration trials on a UK Ministry of Defence Low-Cost Air Defence Effectors (LCADE) contract, a signal that its propulsion-focused approach is being tested against urgent defence and sovereign supply-chain needs.
Why it matters
The funding arrives at a moment of rapid change in aviation and defence. The widespread use of low-cost one-way attack drones has altered the economics of air defence, and the UK has committed significant sums to counter-drone and autonomous systems capabilities under its Defence Investment Plan. Greenjets’ work on propulsion and integrated aircraft design targets the performance constraints—speed, noise, thermal signature and manufacturability—that determine whether interceptors can keep pace with fast unmanned threats.
A successful transition from development to production would not only supply military programmes but also strengthen UK sovereign capability across aerospace supply chains, from engines to airframes. The company’s forthcoming demonstration trials under LCADE will be a practical test of those claims.
Inside the product
Greenjets says it is developing a common technology stack that spans electric ducted fans through to geared turbofan engines, with a focus on integration and manufacturability. That stack is intended to speed iteration and allow the same core propulsion and integration work to be applied across multiple aircraft and launch applications.
Operationally the company has expanded its UK footprint: facilities grew from about 12,000 to nearly 70,000 square feet in the last year, and headcount is set to increase from roughly 160 to more than 250 as the firm shifts toward production. Management says the Series A will support scaling that production and the delivery of thousands of systems over the next 12 months, while advancing the propulsion, aircraft and launch technology portfolio and expanding international partnerships.
Who are the investors?
The round is led by Blossom Capital, with participation from the NATO Innovation Fund, the National Security Strategic Investment Fund and existing backers. Blossom Capital is a Europe-focused Series A venture firm; other participants bring a mix of defence and private capital.
Blossom Capital has backed a number of high-growth European technology companies. Its participation indicates continued venture interest in deep-technology aerospace propositions that can be manufactured at scale.
In the announcement, Max Frenkel, Partner at Blossom Capital, said:
Greenjets gives aircraft builders what no legacy architecture can: speed, silence, range and instant response, tuned to whatever the mission demands. That is why their propulsion is being designed into platforms across the full spectrum of autonomous flight. Anmol, Guido and the team stand out for a relentless focus on delivery and customer satisfaction.
In the announcement, Patrick Schneider-Sikorsky, Partner at NIF, said:
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.
In the announcement, Edmund Phillips, Investment Partner NSSIF, said:
NSSIF is proud to be part of Greenjets future. The company presents a special combination of a deep technological moat and roadmap of high value applications in defence and civil use cases over the long term, with a platform for mass production and rapid iteration that addresses acute defence needs in the present. Greenjets is already making a material contribution to the UK's security and prosperity, and this is set to scale massively.

Founder perspective
In the announcement, Anmol Manohar, CEO, and Guido Monterzino, CTO at Greenjets, said:
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.
The bigger picture
Greenjets’ raise and its LCADE selection underline two broader trends in the UK and Europe: first, a push to rebuild sovereign capability in critical aerospace subsystems such as propulsion; second, growing convergence between commercial aerospace technologies and defence requirements, especially around unmanned systems. The LCADE programme is part of a five-nation LEAP effort across the UK, Poland, France, Italy and Germany; the UK is the first partner to put suppliers on contract and will use demonstration trials to validate solutions.
If Greenjets can move from prototypes to volume production while meeting MOD performance requirements, it would provide a blueprint for how UK startups can supply both defence and civil markets. The deal also highlights continued appetite from public and private investors for firms that combine IP, manufacturing plans and routes into government programmes.
This funding and the upcoming trials will be watched closely by UK and European policymakers and investors as they consider how to strengthen domestic aerospace supply chains and deter emerging threats in the air domain.
