Ro-ark Aerospace Secures £22m to Advance Autonomous Defence Systems

Ro-ark Aerospace Limited, a London-based company specialising in autonomous defence systems and sensor networks, has successfully raised £22m in a recent funding round. The capital infusion, with an allotment date of April 4, 2026, and a filing date of April 6, 2026, positions the company to further develop and deploy its drone detection and disruption systems.

Founded on November 30, 2023, Ro-ark Aerospace addresses the growing challenge of unauthorised drone activity by offering a "detection as a service" model. Their target market spans governments, military organisations, and the private sector globally, providing critical solutions for airspace security. The company's latest available accounts show a revenue of £36.9m, with a reported loss of £-16,561,770 and a team of 49 employees. Further details regarding the company's valuation or specific investors in this round were not disclosed.

The £22m funding round represents a significant investment in Ro-ark Aerospace's capabilities. While specific investors were not named and no previous funding rounds were detailed in the provided data, this capital is expected to fuel the company's growth and technological advancements in the rapidly evolving defence technology sector.

This funding round for Ro-ark Aerospace aligns with a broader trend of increased investment in UK defence technology and deep tech sectors. The UK government has demonstrated a strong commitment to accelerating defence innovation, with a major £5 billion technology investment planned, including over £4 billion specifically directed towards autonomous systems. This initiative aims to enhance the accuracy and efficacy of the Armed Forces and boost export potential. The government has also committed to increasing defence spending to 2.5% of GDP from 2027, with long-term aspirations of reaching 5% of national income on national security by 2035.

In 2025, the UK allocated £61.4 billion to defence tech investment, maintaining one of Europe's largest defence budgets. This period saw annual equity inflows into the European defence tech ecosystem jump to £826 million, reflecting strong growth over the past decade. Furthermore, the newly formed UK Defence Innovation (UKDI) announced in December 2025 that it would inject over £142 million into drone and anti-drone weapons in its first year of operation, with approximately £30 million specifically for counter-drone technology to protect the UK homeland. This highlights a clear governmental and strategic focus on the very area Ro-ark Aerospace operates within.

The drone detection market itself is experiencing substantial growth. The global drone detection market size was valued at USD 1,783.6 million in 2025 and is projected to grow to USD 6,123.5 million by 2034, exhibiting a compound annual growth rate (CAGR) of 14.8% during the forecast period. The UK drone detection market alone is estimated at around USD 99.7 million in 2026, with demand centred on airports, government facilities, and major events. Buyers are prioritising detection-first solutions due to legal constraints on mitigation, driving investment into RF, radar, and analytics tied to incident response workflows. The UK anti-drone market is also projected to grow at a CAGR of 24.9% from 2025 to 2033, reaching a projected revenue of USD 1,417.5 million by 2033.

Beyond defence, the broader deep tech sector in the UK has shown resilience and growth. In 2025, deep tech companies in the UK raised $4.8 billion in equity funding across 184 rounds, an 18.16% rise compared to 2024. Deep tech now represents 31% of all UK venture capital funding, a threefold increase from a decade ago. AI, a core component of Ro-ark Aerospace's offerings, accounted for 39% of all UK deep tech funding in 2025.

The investment in Ro-ark Aerospace underscores the UK's strategic emphasis on developing advanced capabilities in autonomous systems and counter-drone technology, driven by both national security concerns and a robust deep tech ecosystem.
