^ HMS Enterprise (H88)
The Echo class is a class of multi-purpose hydrographic survey ships in commission with the Royal Navy. The ships are primarily tasked with conducting survey work in support of submarine and amphibious operations, however, the class also has a secondary role in mine countermeasures.
The two vessels of the class are the most recent additions to the Royal Navy's Hydrographic Squadron. Each ship displaces approximately 3,700 tonnes, and is equipped with a state of the art suite of equipment.
The Echo class are the first Royal Navy ships to be fitted with azimuth thrusters. Both azimuth thrusters and the bow thruster can be controlled through the integrated navigation system by a joystick providing high manoeuvrability.
