The UK Royal Navy (RN) has formally accepted into service a new wideband version of the Sonar 2093 variable depth minehunting sonar following the successful completion of first-of-class sea trials on the Sandown-class minehunter HMS Grimsby.
Thales UK was in 2015 awarded a GBP33.5 million (USD43.1 million) contract to deliver the Sonar 2093 Capability Sustainment Programme (CSP) under which the company is embodying a wideband upgrade to enhance system performance against low signature mines. Grimsby is the first of seven Sandown-class minehunters in line to receive the Sonar 2093 CSP fit.
Originally developed in the 1980s, Sonar 2093 is a multifrequency variable depth sonar system capable of search and classification operations in deep and shallow waters, down to depths of about 200 metres.
