Penguin was initially established as the
Balmoral Naval Depot and was also known as
Penguin II in 1941 as a depot for the RAN's main naval base at
Garden Island (on
Sydney Harbour). In addition to accommodation for 700 personnel, as well as all the necessary administrative facilities, the
Balmoral Naval Hospital was built on the site.
Penguin II was commissioned in July 1942, and was renamed as simply HMAS
Penguin in January 1943, when the Garden Island facility was renamed
HMAS Kuttabul. In addition to its role as a depot,
Penguin served as a base for the motor launches responsible for patrolling
Sydney Harbour. After the end of World War II,
Penguin began its service as a training establishment. The RAN Seamanship School was located at
Penguin from 1945 to 1974, while from 1951 to 1954 it was the Navy's National Service Recruit School.
Penguin has also played host to the RAN Staff College and the Security and Naval Police Coxswains School. In addition, a number of operational units of the RAN were once based at
Penguin, including
Clearance Diving Teams One and Two, and the Royal Navy's
4th Submarine Squadron (disbanded 1969). ==Facilities and operational units==
