Public summary
The Collins class is Australia's current conventional submarine force and a central undersea capability for regional deterrence, surveillance and sea control. Diesel-electric propulsion, an Australian combat-system fit, sonar systems and Mk 48 ADCAP torpedoes give the boats meaningful long-range patrol and attack capability. The class remains strategically important while Australia transitions toward its future nuclear-powered submarine pathway.
