United States NavyMaritime service branch of the U.S. militaryMilitary unitThe United States Navy (USN) is the maritimeservice branch of the United States Armed Forces and is designated as the navy of the United States in the Constitution. With 290 combat vessels, it is the world's second largest navy, behind the People's Liberation Army Navy, and by far the largest by displacement, at 4.5 million tons in 2021.
Perth-class destroyerThe Perth-class destroyers were three modified Charles F. Adams-classguided missile destroyers operated by the Royal Australian Navy (RAN). Ordered from Defoe Shipbuilding Company during 1962 and 1963, HMA Ships Perth, Hobart, and Brisbane were the first guided missile armed warships, and the first naval ships of United States design, to enter service with the RAN. All three ships operated during the Vietnam War, while Brisbane also participated in the Gulf War.
Charles F. Adams-class destroyerThe Charles F. Adams class is a ship class of 29 guided-missile destroyers (DDG) built between 1958 and 1967. Twenty-three were built for the United States Navy, three for the Royal Australian Navy, and three for the West German Bundesmarine. The design of these ships (known as project SCB 155) was based on that of Forrest Sherman-class destroyers, but the Charles F. Adams class were the first class designed to serve as guided-missile destroyers.
HMAS Derwent (DE 49)HMAS Derwent (F22/DE 22/DE 49), named for the River Derwent, was a River-class destroyer escort of the Royal Australian Navy (RAN). She was laid down by Williamstown Naval Dockyard in 1959, and commissioned into the RAN in 1964. During the ship's career, she was deployed to South East Asia on 23 occasions, including operations during the Indonesia-Malaysia Confrontation, and escort of the troopship HMAS Sydney to and from the Vietnam War.

Royal Australian NavyNaval warfare branch of the Australian Defence ForceMilitary unitThe Royal Australian Navy (RAN) is the naval branch of the Australian Defence Force (ADF). The professional head of the RAN is the Chief of Navy (CN), Vice Admiral Matthew Buckley. The Chief of Navy is also jointly responsible to the Minister for Defence (MINDEF) and the Chief of the Defence Force (CDF).
Displacement (ship)The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used.
Length overallLength overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may exclude the bowsprit and other fittings added to the hull.
Sinking ships for wreck diving sitesSinking ships for wreck diving sites is the practice of scuttling old ships to produce artificial reefs suitable for wreck diving, to benefit from commercial revenues from recreational diving of the shipwreck, or to produce a diver training site. To avoid undesirable ecological impact, and to maximise utility, the vessel should be selected and prepared, and the site chosen, with due consideration to the local environment.
Battle honourA battle honour is an award of a right by a government or sovereign to a military unit to emblazon the name of a battle or operation on its flags ("colours"), uniforms or other accessories where ornamentation is possible. In European military tradition, military units may be acknowledged for their achievements in specific wars or operations of a military campaign.
Lead shipThe lead ship, name ship, or class leader is the first of a series or class of ships that are all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take five to ten years to build.
Guided-missile destroyerA guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfarescreening for the fleet. Most modern destroyers are of the multi-purpose guided-missile type, and they are widely deployed by advanced navies; in particular, the Arleigh Burke-class guided-missile destroyer is the most numerous class of warship in the US Navy.*As an Amazon Associate I earn from qualifying purchases.
