The UK government has launched a targeted £20 million initiative designed to unearth and accelerate the country’s next “defence unicorn”.

Announced this week by Defence Secretary John Healey, the fund is tailored to fast-track small, innovative British firms into the Ministry of Defence’s (MoD) supply chain – with the explicit hope that one might grow into a billion-pound behemoth.

The phrase “unicorn” — a start-up valued in excess of US$1 billion — has become shorthand for breakthrough success in the tech sector. Yet, until now, such valuations have been rarer in defence and national security, where long-term contracting cycles and heavy incumbent players deter bold newcomers. This new fund, part of a broader government strategy to expand the defence industrial base, seeks to change that narrative.

Mr Healey set out the ambition at the annual ADS industry dinner, emphasising that the UK is “determined to be the best place in the world to start and grow a defence business” and that the military must be “the fastest innovating in NATO.” The underlying message was clear: Britain must ensure its armed forces benefit from the full sweep of modern technological advances — from artificial intelligence and machine learning to autonomy and precision weapons — while also nurturing high-growth companies at home.

The £20 million fund will not hand out grants in the conventional sense. Instead, it offers “accelerated contracts” to small or growth stage businesses — particularly those that have had little or no prior engagement with the MoD — thereby providing both revenue certainty and the cachet that can attract further private investment. To qualify, businesses must be fully or majority UK-owned, reinforcing the government’s focus on domestic capability.

This initiative is also emblematic of a broader shift in defence procurement. Historically, the MoD’s bureaucracy and lengthy processes have been criticised for sidelining agile innovators. To counter this, the new Office of Small Business Growth will help newer entrants navigate procurement, a perennial pain point for startups. The office aims to demystify contracting and lower entry barriers so that smaller firms are not “locked out of the defence sector because of a lack of funding or contracts”.

Moreover, the fund operates within the context of a substantial increase in overall defence spending. The government has committed an additional £2.5 billion in defence SME spend to May 2028, bringing the total to £7.5 billion — a figure that reflects the growing weight of smaller enterprises in national security supply chains.

At the cutting edge of this agenda is UK Defence Innovation (UKDI), a body tasked with identifying and championing technological excellence in areas the MoD deems strategically critical. The body’s remit includes themes such as AI, robotics, autonomy and enhanced precision weapons — sectors where disruptive capability can rapidly alter the battlefield balance.

The timing of the fund’s launch also dovetails with the MoD’s newly introduced “Lite” Enterprise Agreements — simplified commercial frameworks intended to reduce friction for software and AI companies. Early participants in these frameworks include names such as Adarga, Hadean and Oxford Dynamics, which signal the government’s interest in engaging with cutting-edge tech firms rather than traditional hardware suppliers.

This policy direction has its critics. Some industry watchers warn that modest seed funds risk being swallowed by established defence primes or drowned out by larger tech ecosystems such as the United States, where defence tech unicorns have thrived on a far larger scale. Indeed, British tech success stories — particularly those that ultimately list abroad — underscore the challenges of scaling deep technology firms domestically. But supporters argue that this programme directly confronts structural barriers by making early contracting more accessible.

Beyond national pride and economic growth, securing sovereign capability has penetrated the corridors of power with renewed urgency. Russia’s war on Ukraine and accelerating technological competition have underscored the strategic imperative of rapid innovation. Indeed, defence innovation initiatives across the West increasingly prioritise agile, start-up-centric models over legacy procurement systems.

For British entrepreneurs, the £20 million fund represents more than just an early revenue stream; it is a signal that government is prepared to share risk and lend credibility. As Mr Healey put it, the programme rewards “risk-takers and innovators” and gives them the belief that they will be backed in their ambitions.

Whether the fund will indeed produce Britain’s next defence unicorn remains to be seen. But it already reflects a more strategic recognition: that in an era of unprecedented geopolitical uncertainty, the fusion of commercial innovation with defence capability must go hand in hand. By lowering barriers and lighting a clearer path from prototype to procurement, the UK hopes not just to build cutting-edge tools for its Armed Forces, but to foster a new generation of world-leading defence enterprises rooted in British ingenuity.
