Mulloka

Mulloka was an Australian-designed sonar system installed on ships of the Royal Australian Navy.¹ It was optimised for the warm and shallow waters common off Australia and used a high frequency.² The system was developed during the 1970s, with River-class destroyer escort HMAS Yarra being used as the trial ship for Mulloka between 1974 and 1979.³ These trials ended on 17 August 1979 when the system was accepted for service.⁴ Mulloka was subsequently fitted to all the RAN's River-class destroyer escorts along with Adelaide-class frigates HMAS Melbourne (FFG 05) and HMAS Newcastle (FFG 06). It was replaced by an improved variant of the Spherion sonar in use on the Anzac-class frigates as part of the FFG Upgrade program.¹⁵
