SM400 USV. High-speed, operational flexibility and resilience

SM400 is a fully enclosed 7.2-meter, high-speed tactical USV. Its modular mission architecture and large payload bay support fleet shadowing, conduct electronic warfare and ISR missions, deliver payloads and execute high-risk tasks.

Multiple SM400 USVs can operate as co-ordinated “wolf pack” swarms, delivering mass, speed and persistence across contested maritime environments.

An integrated HVAC system provides environmental resilience in extreme hot and cold weather conditions and events, with an additional generator for payload power generation.

Why SM400?

TRL 9, 500kg payload.

Autonomous precision: Track and engage static or moving targets using onboard EO/IR camera processing.
Endurance at sea: Long-range offshore operations up to 950 NM.
EW resilient: PACE communications, CRPA GNSS, SATCOM, and advanced terrestrial navigation.
Integrated HVAC system: delivering environmental resilience.

Command and control: Set intent and re-task in real time—autonomy handles execution and synchronisation.
