HNoMS Haakon VII (A537)
USS ''Gardiners Bay'' (AVP-39) was a United States Navy seaplane tender in commission from 1945 to 1958 that saw service in the latter stages of World War II and in the Korean War. After her decommissioning, she was transferred to Norway, and she served in the Royal Norwegian Navy as the training ship HNoMS ''Haakon VII'' (A537) from 1958 to 1974. Construction and commissioning ''Gardiners Bay'' was launched on 2 December 1944 at Houghton, Washington, by the Lake Washington Shipyard, sponsored by Mrs. George L. Richard. She commissioned at the Puget Sound Naval Shipyard at Bremerton, Washington, on 11 February 1945. United States Navy service World War II ''Gardiners Bay'' departed Seattle, Washington, on 1 March 1945 for shakedown out of San Diego, California, which she completed on 20 April 1945. She then proceeded via Pearl Harbor, Hawaii, to Eniwetok in the Marshall Islands to tend the seaplanes of Patrol Bombing Squadron 19 ( VPB-19) in a 10-day training period, the ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Squadron (aviation)
A squadron in an air force, or naval or army aviation service, is a unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flights, depending on aircraft type and air force. In most armed forces, two or more squadrons will form a group or a wing. Some military forces (including the United States Air Force, United States Space Force, French Air and Space Force, Royal Air Force, German Air Force, Royal Netherlands Air Force, Belgian Air Component and Republic of Singapore Air Force) also use the term "squadron" for non-flying ground units (e.g. radar squadrons, missile squadrons, air defense squadrons, aircraft maintenance squadrons, security forces squadrons, civil engineering squadrons, range operations squadrons, range management squadrons, weather squadrons, medical squadrons, etc.).

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebach M ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see #Name, name) is an Anti-aircraft warfare, anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns. For its time, the Bofors 40 mm L/60 was perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies of World War II, Allies and some Axis powers such as Nazi Germany and Hungary. In the po ...

Gunnery Officer
The gunnery officer of a warship was the officer responsible for operation and maintenance of the ship's guns and for safe storage of the ship's ammunition inventory. Background The gunnery officer was usually the line officer next in rank to the executive officer. As shipboard guided missiles and torpedoes became more effective than naval artillery, guns were included within a weapons department replacing the older gunnery department. The weapons department is supervised by a weapons officer who may have a subordinate gunnery officer supervising the ship's guns. See also *Naval artillery Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for more specialized roles in surface warfare such as naval gunfire support (NGFS) and anti-aircraft warfare (AAW) engagements. ...

5"/38 Caliber Gun
The Mark 12 5"/38-caliber gun was a United States dual purpose gun, dual-purpose Naval artillery, naval gun, but also installed in single-purpose mounts on a handful of ships. The 38-Caliber (artillery), caliber barrel was a mid-length compromise between the previous United States standard 5"/51 caliber gun, 5"/51 low-angle gun and 5-inch/25-caliber gun, 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 Caliber (artillery), calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of Shell (projectile)#Separate loading cased charge, semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first n ...
