Ukraine explores Dutch fiber-optic hydroacoustic systems for ASW

Bottom line

UK explores mounting OptiArray flexible fiber-optic hydroacoustic systems on civilian vessels for anti-submarine warfare, developed by Dutch firm Optics11.

Why it matters

Highlights Dutch technological contributions to allied ASW capabilities and the potential for dual-use civilian-military integration in maritime domains, which could complicate adversary submarine detection and counter-surveillance efforts.

Signals indicate that the UK is exploring the integration of OptiArray flexible fiber-optic hydroacoustic systems, developed by the Dutch firm Optics11, onto civilian vessels for anti-submarine warfare (ASW). The system is capable of detecting targets up to 100km without electromagnetic emissions, allowing it to evade electronic warfare detection. This represents a potential shift in maritime surveillance and ASW tactics utilizing commercial infrastructure.
