The two ships of Echo class are the latest vessels to join the Royal Navy's Hydrographic Squadron. Each ship displaces approximately 3,500 tonnes, and is equipped with a state of the art suite of equipment, including:
- Multi beam echo sounder
- Single beam echo sounder
- Survey Planning and Processing Systems
- Side-scan sonar
- Oceanographic Probe and sensors
- Undulating Oceanographic Profiler
- Doppler Current Log
- Sub-bottom Profiler
- Bottom Sampling Equipment
- Survey Motor Boat fitted with multi-beam sonar and sidescan sonar
The two ships follow the same type of crew rotation pattern as HMS Scott, in that two-thirds of their crew is needed to keep the ship operational, with the remaining one-third ashore. This allows each ship to be available for deployment for up to 330 days a year. As with other Royal Navy survey vessels, Echo and Enterprise can also be used to support mine warfare vessels.
