This contract ensures that the Integrated Sonar System installed on the Royal Australian Navy’s (RAN) DDGs, which is comprised of a Hull Mounted Sonar and a Towed Variable Depth Sonar joined by an integrated sonar processing suite to provide an advanced multi-sensor sonar capability, continues to support the operational requirements of the RAN.

The Hobart class is a ship class of three air warfare destroyers (AWDs) built for the Royal Australian Navy (RAN).

Each destroyer will have a length overall of 147.2 metres (483 ft), a maximum beam of 18.6 metres (61 ft), and a draught of 5.17 metres (17.0 ft). At launch, the ships will have a full-load displacement of 6,250 tonnes (6,150 long tons; 6,890 short tons). The Hobarts have been designed to allow for upgrades and installation of new equipment, with a theoretical maximum displacement of 7,000 tonnes (6,900 long tons; 7,700 short tons).

The combined diesel or gas turbine (CODOG) propulsion arrangement consists of two General Electric Marine model 7LM2500-SA-MLG38 gas turbines, each generating 17,500 kilowatts (23,500 hp), and two Caterpillar Bravo 16 V Bravo diesel engines, each providing 5,650 kilowatts (7,580 hp). These drive two propeller shafts, fitted with Wärtsilä controllable pitch propellers.

The ships' maximum speed is over 28 knots (52 km/h; 32 mph), with a range of over 5,000 nautical miles (9,300 km; 5,800 mi) at 18 knots (33 km/h; 21 mph).
