Royal Australian Navy in the context of "Tomahawk (missile family)"

The naval operations in the Dardanelles campaign (17 February 1915 – 9 January 1916) took place against the Ottoman Empire during the First World War. Ships of the Royal Navy, French Marine nationale, Imperial Russian Navy (Российский императорский флот) and the Royal Australian Navy, attempted to force a passage through the Dardanelles Straits, a narrow, 41-mile-long (66 km) waterway connecting the Mediterranean Sea with the Sea of Marmara and the Black Sea further north.

The naval operations were defeated by the Ottoman defenders, mainly through use of naval mines. The Allies conducted the Gallipoli campaign, a land invasion of the Gallipoli peninsula to eliminate the Ottoman artillery along the straits before resuming naval operations. The Allies also passed submarines through the Dardanelles to attack Ottoman shipping in the Sea of Marmara.

The Australian Defence Force Academy (ADFA) is a tri-service military academy that provides military and academic education for junior officers of the Australian Defence Force in the Royal Australian Navy (RAN), Australian Army and Royal Australian Air Force (RAAF) as well as international trainee officers from a variety of countries. In 2016, the academy began accepting civilian students in its undergraduate courses.

Tertiary education is provided by the University of New South Wales' Canberra campus, known as UNSW Canberra at ADFA, which is the awarding body for ADFA qualifications. Apart from educating future leaders of the Australian Defence Force, UNSW Canberra also provides postgraduate programs and short courses both to Department of Defence personnel and the general public.

A naval air station (NAS) or navy airbase is a military air base under the command of a navy, dedicated to the use of aircraft for naval operations. These bases are typically populated by squadrons, groups or wings of navalised aircraft, their various support facilities, and other tenant commands.

The term "naval air station" is used by many countries' navies, such as the United States Navy, the Royal Australian Navy, the Royal Navy, and the Indian Navy. In the case of the U.S. Navy, similar facilities in the U.S. Marine Corps are known as Marine Corps Air Stations and facilities in the U.S. Coast Guard are known as Coast Guard Air Stations.

The Australian Defence Force (ADF) is the military organisation responsible for the defence of Australia and its national interests. It consists of three services: the Royal Australian Navy (RAN), the Australian Army and the Royal Australian Air Force (RAAF). The ADF has a strength of just over 90,000 personnel and is supported by the Department of Defence alongside other civilian entities also members of the Australian Defence Organisation.

During the first decades of the 20th century, the Australian Government established the armed services as separate organisations, with each service having an independent chain of command. In 1976, the government made a strategic change and established the ADF to place the services under a single headquarters. Over time, the degree of integration has increased, and tri-service headquarters, logistics, and training institutions have supplanted many single-service establishments. The ADF has been deployed around the world in combat, peacekeeping and disaster-relief missions.

The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead. It was also the first military battle between aircraft carriers.

To strengthen their defensive position in the South Pacific, the Japanese decided to invade and occupy Port Moresby (in New Guinea) and Tulagi (in the southeastern Solomon Islands). The plan, Operation Mo, involved several major units of Japan's Combined Fleet. Two fleet carriers and a light carrier were assigned to provide air cover for the invasion forces, under the overall command of Admiral Shigeyoshi Inoue. The U.S. learned of the Japanese plan through signals intelligence and sent two U.S. Navy carrier task forces and a joint Australian-American cruiser force to oppose the offensive, under the overall command of U.S. Admiral Frank J. Fletcher.

A midshipman is an officer of the lowest rank in the Royal Navy, United States Navy, and many Commonwealth navies. Commonwealth countries which use the rank include Canada (Naval Cadet), Australia, Bangladesh, Namibia, New Zealand, South Africa, India, Pakistan, Singapore, Sri Lanka, and Kenya.

In the 17th century, a midshipman was a rating for an experienced seaman, and the word derives from the area aboard a ship, amidships, either where he worked on the ship, or where he was berthed. Beginning in the 18th century, a commissioned officer candidate was rated as a midshipman, and the seaman rating began to slowly die out. By the Napoleonic era (1793–1815), a midshipman was an apprentice officer who had at least nominally served at least three years as a volunteer, officer's servant or able seaman, and was roughly equivalent to a present-day petty officer in rank and responsibilities. After serving at least three years as a midshipman or master's mate, he was eligible to take the examination for lieutenant. Promotion to lieutenant was not automatic, and many midshipmen took positions as master's mates for an increase in pay and responsibility aboard ship. Midshipmen in the United States Navy were trained and served similarly to midshipmen in the Royal Navy, although unlike their counterparts in the Royal Navy, a midshipman was a warrant officer rank until 1912.

The Australian Army is the principal land warfare force of Australia. It is a part of the Australian Defence Force (ADF), along with the Royal Australian Navy and the Royal Australian Air Force. The Army is commanded by the Chief of Army (CA), who is subordinate to the Chief of the Defence Force (CDF) who commands the ADF. The Department of Defence supports the ADF and the Army.

The Australian Army was formed in 1901 as the Commonwealth Military Forces, through the amalgamation of the colonial forces of Australia following the Federation of Australia. Although Australian soldiers have been involved in a number of minor and major conflicts throughout Australia's history, only during the Second World War has Australian territory come under direct attack.
