Lockheed Martin Opens London Office and Commits $100 Million to Back UK and European Deep Tech Founders

Lockheed Martin Ventures, the US defence giant's venture capital arm, opened a London office this week and confirmed it will deploy at least $100 million into UK and European startups, giving founders building sovereign and defence relevant technology a new, well capitalised route to serious capital.

For a UK deep tech founder, the announcement matters less for its size than for what it signals about who is now willing to write the cheque. Founders building autonomy, sovereign infrastructure, secure compute or other dual use hardware have historically had a thin set of backers to choose from: generalist venture funds that understand software economics but not defence procurement cycles, and a small pool of specialist angels who rarely have the capital to lead a serious round. A defence prime with Lockheed Martin's balance sheet entering that gap directly changes the calculation for founders deciding whether a UK or European base is compatible with raising at scale.

The London office follows a decision in April to expand Lockheed Martin Ventures' total firepower from $400 million to $1 billion, the largest single increase in the unit's history.

That capital is now being pushed outward: Lockheed Martin Ventures Europe is intended to accelerate the flow of US defence venture capital into the UK and European ecosystem, rather than requiring European founders to raise from, or relocate toward, US based investors. The unit has already backed more than 120 companies globally with over $500 million in cumulative investment, giving it a track record that predates this European expansion by several years.

The timing is not incidental. European governments have been increasing defence spending and explicitly looking to strengthen domestic and allied supply chains rather than depend solely on US primes, a shift that has already reshaped procurement conversations across the UK, Germany, France and the Nordics. A US defence contractor opening a dedicated European investment office reads as a hedge against exactly that trend: rather than watching European sovereign capability build up independently, Lockheed Martin is positioning itself to hold equity in the companies most likely to benefit from it.

For founders, the practical upside goes beyond the cheque itself. A strategic investor with Lockheed Martin's procurement relationships and testing infrastructure can offer things a purely financial investor cannot, including credible routes to government contracts, access to defence-grade testing environments, and, eventually, acquisition as an exit path that does not depend on an IPO market that has been unreliable for hardware and defence technology companies. That combination, capital plus a plausible commercial and exit pathway, has been genuinely scarce for UK founders building outside pure software.

It would be premature to call this a solved problem. One well resourced strategic investor does not replace a deep, diversified venture ecosystem, and founders building dual use technology will still need generalist funds willing to co-invest alongside a strategic like Lockheed Martin Ventures. But the entry of a $1 billion venture arm with a dedicated European mandate is a meaningful addition to the realistic set of investors UK deep tech and defence founders can approach, at a moment when that set has been thin.

Key Takeaways

• Lockheed Martin Ventures has opened a London office and will commit at least $100 million to UK and European startups.

• The move follows an April decision to expand the fund from $400 million to $1 billion, the largest increase in its history.

• The unit has already backed more than 120 companies globally with over $500 million in cumulative investment.

• For UK deep tech and defence founders, the entry adds a well resourced, sector specific investor to a funding landscape that has been dominated by generalist funds unfamiliar with defence procurement.

• The launch lands as European governments increase defence spending and prioritise domestic and allied supply chains, a backdrop that gives strategic investors like Lockheed Martin Ventures a commercial reason to hold equity in the companies benefiting from that shift.
