HMAS Ovens

WA Maritime Museum - Joy of Museums - HMAS Ovens

HMAS Ovens (S 70) was an Oberon-class submarine of the Royal Australian Navy (RAN). The vessel was named for Irishman and Australian explorer John Ovens (1788-1825) and for whom the Victorian river Ovens was named. Ovens was the first RAN submarine to deploy with the ANZUK force.

Ovens became the first RAN submarine to fire an armed Mark 48 torpedo, when she sank the decommissioned Bathurst-class corvette HMAS Colac in 1987. On her return to port, Ovens flew a ‘Jolly Roger’ to indicate a successful mission. The first time a RAN submarine had done so.
