HMS Echo and HMS Enterprise are two multi-role hydrographic survey ships commissioned by the Royal Navy. They form the Echo class of survey vessels. They were built by Appledore Shipbuilders in Devon in 2002.
Echo and Enterprise 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.
These ships are designed to conduct survey
operations in support of submarines or amphibious operations. They can
provide almost real-time tailored environmental information, and also
have a secondary role as a Mine Countermeasure Tasking Authority
platforms, for which they are capable of embarking a dedicated Mine
Counter Measures command team.
