SUBMARINES: Aussie Collins-class Sub “Sinks” US Boat
December 13, 2003: Someone passing the Pentagon during the end of September would have noticed the lights burning brightly all night at the US Navy’s Submarine Directorate. An Australian Type 471 Collins-class diesel-electric submarine had just “sunk” an unidentified US Navy submarine (most likely a Los Angeles-class nuclear attack sub, which the US Navy asserts is superior to any other non-US sub in the world today). The diesel-powered Collins-class is relatively modest, with a submerged displacement of approximately 3,300 tons. The nuclear-powered Los Angeles-class -- designed to sink Soviet submarines during the Cold War -- is far more sophisticated and typically displaces over 6,900 tons submerged.
In late September HMAS Waller (S-75) had “sunk the pride of the US nuclear submarine fleet” with practice torpedoes during an unspecified exercise. HMAS Waller was launched in 2001. The RAN ordered six of these subs from Holland in 1987; the last – HMAS Rankin – was launched earlier this year. The class was designed by Swedish shipbuilders Kockums.
The US Navy has declined to identify the sub involved or provide details about the exercise. The unidentified US boat was “sunk” with a Mk 48 practice torpedo. Both RAN and USN subs use this weapon. [b]Also during the exercise, Waller’s sister ship, HMAS Rankin, "sank" an unidentified Singaporean ASW ship.

Thumbs up to the Aussie..
If the RAN is good enough to whack USN's sub then its no surprise that they can kick RSN's ASW boat's ass as well..
Most important is that RSN can learn and benefit from the excerise.

Maybe RSN should consider sending our future sub skippers for training in Australia too.
