When most people think of warships, they think big guns, missiles & helicopters. But for the Royal Navy's hydrographic vessels the most important systems they carry aren’t necessarily their weapons, but their state-of-the-art underwater survey suites.
Four CTG SeaSoar undulating oceanographic recorders (UORs) are currently in use on the Royal Navy’s survey vessels, HMS ECHO and HMS ENTERPRISE. These UORs are towed behind the ships collecting a vast range of information using highly advanced oceanographic sensors. Collecting enough accurate data to maintain the Admiralty’s collection of 3,300 nautical charts (used by seafarers all over the world, not just the RN) is a mammoth task but HMS Enterprise and her sister ship HMS Echo are well equipped for the job. Data from the CTG sensors is displayed in real time providing the operator with a comprehensive mapping system. In addition this data is dispatched to the UK Hydrographic Office for analysis and inclusion into navigational charts
