Multiple maritime defence technology companies developing autonomous and uncrewed surface vessels (USVs) have been featured on Resilience Media's inaugural 100 Startups to Watch in 2026 list, alongside aerospace and drone companies that have long dominated defence tech headlines. The featured maritime companies, including Acua Ocean, Kraken, Saronic, Havoc Ai, Polar Mist and Seasats, represent a sector that has undergone a transformation as profound as the uncrewed aerial systems (UAS) revolution.

Why it matters

The maritime defence tech sector's prominence on the Resilience Media list reflects the growing importance of autonomous and uncrewed surface vessels in the modern defence innovation ecosystem. As defence budgets refocus on capability, the USV market is poised for significant growth, mirroring the trajectory of the drone industry.

The details

The maritime companies featured on the list span both sides of the Atlantic. In 2025, UK-based Acua Ocean's Pioneer became the first USV to receive certification under the UK Maritime and Coastguard Agency's Workboat Code Edition 3 Annex 2. Acua Ocean has been awarded multiple UK Ministry of Defence demonstration contracts and is building the Pioneer Mk2 USV. Saronic, the Austin-based developer of autonomous surface vessels, has recently raised a $1.75 billion investment round and acquired a Louisiana shipyard to accelerate production for US Navy programmes.
