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.
