Sub Base Platypus Torpedo Factory

Opened in September 2023, the Torpedo Factory at Sub Base Platypus is an excellent addition to this heritage site. Managed by the Harbour Trust, the old factory was partially demolished and revitalised as an open public space.

Getting There

We used public transport, getting the train to Milsons Point Station and then walking for 10 minutes. If you prefer to drive, there is parking available on site.

History of the Site

Opened in 1942 during World War Two the factory produced torpedoes for Allied forces. Many of the employees were women, due to many men being in the armed forces. Commemorated at the site with murals, it’s a great reminder of their contribution during the war. Post war, the torpedo workshops continued to service the British Navy submarine fleet based at HMAS Penguin and the Royal Australian Navy’s destroyer fleet.

The entire base was closed in 1999 when the Royal Australian Navy moved its Collins-class submarines to Western Australia.

The Site Now

The old factory features several interesting display that explain the site’s history. These range from a Torpedo Mark VIII, information boards and murals with photos and signs from the factory. There is also a car park with electric charging stations.
