Defence giants spend a record $4.1bn on AI and drone start-ups

The world's biggest arms companies have committed $4.1bn to AI, drone and cyber start-ups so far in 2026, the largest annual total on record. The number, drawn from Dealroom data cited by City AM, marks a threshold: BAE Systems, Lockheed Martin and Airbus are no longer building the next generation of military capability only in their own labs. They are funding and acquiring the start-ups that build it.

Lockheed Martin announced on 16 July that it will earmark at least $100m for UK and European defence technology start-ups and more than doubled its venture investment fund, from $400m to $1bn, according to the company's press release. BAE Systems has committed €50m (about $54m at mid-2026 rates) to two European defence venture funds, Lakestar and Expeditions, Sifted reports. Airbus has become the anchor investor in a new €500m (about $540m) fund targeting dual-use technologies with both military and commercial buyers.

The start-ups themselves are raising at a pace that would have looked outlandish two years ago. Quantum Systems, the German drone maker, raised $1.2bn earlier this month at a valuation of roughly $8bn, City AM reports. Kraken Technology, a UK maritime defence firm, secured $175m at a $1bn valuation with backing from Rheinmetall, the German arms group. Those rounds were not the work of pure financial investors; they were led, in part, by the same primes now writing cheques through their venture arms.

The White & Case count, 42 defence mergers and acquisitions globally in the first half of 2026, up 56 per cent on the same period a year earlier, sits in the same year as the Dealroom record for a reason: AI, autonomy, drones, maritime, cyber, space and dual-use are areas where commercial technology is moving faster than any single contractor's internal R&D cycle. Buying or funding a start-up gets the capability onto a balance sheet in months rather than the years a clean-sheet programme would take.

UK policy is bending to the same logic. Ministers awarded £708m (about $899m at mid-2026 rates) to BAE Systems and Team Tempest partners for the Future Combat Air System programme, a sixth-generation fighter effort that pulls in AI, robotics, digital engineering and advanced manufacturing across roughly 600 UK suppliers. The Technology and Growth Alliance, a public-private grouping that includes BAE Systems, Thales, Leonardo and the European defence AI firm Helsing, is targeting 20 defence technology spinouts out of UK universities, as DefenceMatters reports.

Whether the start-up pipeline can deliver fielded capability faster than the internal R&D it is partly replacing, and whether the eye-catching valuations, Quantum Systems at roughly $8bn most prominently, reflect capability that will reach the field or simply capital chasing a defence label, are the open questions behind the $4.1bn total. A second, related question follows the money into procurement: as public contracts and private capital increasingly route through the same handful of primes, accountability for how those bets turn into deployable systems becomes harder to trace, not easier. The pattern was also picked up in trade press in Kyiv and in Seoul, confirming the cross-border read on the same Dealroom figures.

The pattern that crossed a measurable threshold this year is not a one-quarter spike. Dealroom's running total still has five months to run, and Lockheed's expanded $1bn fund is now deployable rather than announced. The next test is whether the start-ups the primes are buying into start shipping systems that work, at the scale the public is now being asked to underwrite.
