Australia's two O Class submarines, HMAS Oxley and HMAS Otway, in 1927

The Royal Australian Navy Submarine Service is the collective name of the submarine element of the Royal Australian Navy. The Service currently forms the Navy's Submarine Force Element Group and consists of six Collins class submarines. The Submarine Service has been established four times, with the initial three attempts being foiled by combat losses and Australia's economic problems. The modern Submarine Service was established in 1964 and has formed an important element of the Australian military's capacity since that date. While the Submarine Service has not seen combat since World War I Australian submarines have conducted extensive surveillance operations throughout South East Asia.
