Kraken Technology Group, a London-based developer of uncrewed autonomous maritime vehicles, has secured $175 million in a Series B funding round. The investment was led by DTCP and included contributions from the British Business Bank, Nato Innovation Fund, Rheinmetall, and others. The funding round was announced on July 9, 2026, marking Kraken as Europe’s newest defence unicorn, according to sifted.eu.
The Series B round attracted a diverse group of investors including Inocea Group, HICO, Thesiger Capital Group, BOKA Capital, Supernova Invest, and Hakluyt Capital. Kraken specializes in maritime defence vessels such as the K3 Scout for surveillance and precision strikes, the K4 Manta for high-speed surface and covert sub-surface operations, and the K5 Kraken, an unmanned surface vehicle designed for coastal combat. The company holds contracts with the UK Ministry of Defence, underscoring its strategic role in European security.
This funding round highlights growing investor interest in maritime technology within the defence sector, as European security concerns rise. While drones and AI have dominated defence investment, maritime tech is gaining traction due to its focus on protecting Europe’s coastal and subsea infrastructure. Kraken’s $175 million raise positions it alongside other defence startups benefiting from increased venture capital attention, reflecting a shift towards diversified security technologies.
Kraken Technology Group’s new capital will support the expansion and development of its autonomous maritime vehicle portfolio. The company’s contracts with the UK Ministry of Defence and its recent funding round place it at the forefront of Europe’s maritime defence innovation landscape as of July 2026.
