Evidence & current status
A live HamiltonJet project brief supports the 11.2 m dimensions, twin-waterjet propulsion and 40-knot installation baseline. Current TKMS pages support modular sensor options, transportability and service context, supplemented by Royal Navy reporting. Lightship mass and numerical payload capacity are not established from the accessible primary sources; figures from an unavailable legacy brochure have been omitted. Performance and installed equipment remain configuration-dependent.
Role & capabilities
- Mine-countermeasure payload carriage
- Hydrographic survey support
- Remote deployment of offboard sensors
