The Echo A70 class was a class of inshore survey vessels built for the British Royal Navy in 1958–1959. The class was designed to operate in close waters such as harbour approaches, shipping lanes, rivers and estuaries. Together, the ships of this class formed the Royal Navy's Inshore Survey Squadron.
HMS Echo H87 is the first of two multi-role hydrographic survey ships commissioned by the Royal Navy. With her sister ship, HMS Enterprise, they form the Echo class of survey vessels. She was built by Appledore Shipbuilders in Devon in 2002 and is the ninth Royal Navy vessel to carry the name.
