HMAS Orion

HMAS Orion (S 61) was an Oberon-class submarine of the Royal Australian Navy (RAN). One of six submarines ordered by the RAN during the 1960s, Orion, named after the constellation in a break from ship-naming tradition, was built in Scotland and commissioned in 1977. Orion was one of two Oberon-class submarines designed for intelligence gathering and conducted regular patrols in Soviet, Indian and Chinese waters to gather information regarding enemy capabilities. The Royal Australian Navy (RAN) is the naval branch of the Australian Defence Force (ADF). The professional head of the RAN is Chief of Navy (CN)[2] Vice Admiral Mark Hammond. The Chief of Navy is also jointly responsible to the Minister for Defence (MINDEF) and the Chief of the Defence Force (CDF). The Department of Defence, which is a part of the Australian Public Service, supports the ADF, and ergo, the Royal Australian Navy.[
