In 1985, off the island of Kauai in Hawaii, HMAS Ovens became only the second conventional submarine in the world—and the first Oberon—to fire a sub-surface-launched Harpoon missile, successfully hitting the target over the horizon. Consequently, the designation for the Australian Oberons changed from SS to SSG.
This ship is not assigned to any other category.
