List Of Inactive United States Navy Helicopter Squadrons
There are hundreds of US Navy aircraft squadrons which are not currently active dating back to before World War II (the U.S. Navy operated aircraft prior to World War I, but it did not organize them in squadrons until after that war). To be more accurate: there are hundreds of former U.S. Navy aircraft squadrons which have been disestablished and no longer exist and there are approximately 40 or so U.S. Navy aircraft squadrons which have been deactivated and which currently exist only "on paper" in an inactive status. These disestablished and/or deactivated squadrons are sometimes incorrectly referred to as "decommissioned" squadrons, but proper usage prior to 1998, was that squadrons were "established" and "disestablished" and after 1998, squadrons are "established", "deactivated" and sometimes "reactivated". It has never been correct to refer to U.S. Navy aircraft squadrons as being "commissioned" and "decommissioned", ships are commissioned and decommissioned, U.S. Navy aircraft ...

HU-1
Ribosomal protein S6 kinase alpha-1 is an enzyme that in humans is encoded by the ''RPS6KA1'' gene. Function This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 nonidentical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. Interactions RPS6KA1 has been shown to interact with: * IκBα, * MAPK1, * TOB1 * TSC2, and * YWHAB 14-3-3 protein beta/alpha is a protein that in humans is encoded by the ''YWHAB'' gene.

Bell UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, ca ...

Helicopter Combat Support Squadron 4 (United States Navy - Insignia)
Helicopter Combat Support Squadron FOUR (HC-4) was a United States Navy helicopter squadron based at Naval Air Station Norfolk, Virginia. Nicknamed the "Black Stallions", they flew the Sikorsky CH-53E Super Stallion and MH-53E Sea Dragon helicopters. History The Black Stallions were established on May 6, 1983 as a heavy lift combat support squadron and designated HC-4 (for Helicopter Combat). On July 1, 1960 Helicopter Utility Squadron Four (HU-4) was established at NAS Lakehurst, New Jersey, and tasked with the logistic support of non-aviation ships of the U.S. Atlantic Fleet. To describe its mission more accurately, the squadron was redesignated as Helicopter Combat Support Squadron Four in July 1965, and HC-4 was born. The unit was equipped with the Kaman UH-2A Seasprite light transport helicopter. Eight years later, the young squadron assumed a new mission of Helicopter Anti-submarine Warfare and was renamed HSL-30. In the early 1980s, the advent of the Sikorsky CH-53E Sup ...

SH-2F
The Kaman SH-2 Seasprite is a ship-based helicopter originally developed and produced by American manufacturer Kaman Aircraft Corporation. It has been typically used as a compact and fast-moving rotorcraft for utility and anti-submarine warfare missions. Development of the Seasprite had been initiated during the late 1950s in response to a request from the United States Navy, calling for a suitably fast and compact naval helicopter for utility missions. Kaman's submission, internally designated as the ''K-20'', was favourably evaluated, leading to the issuing of a contract for the construction of four prototypes and an initial batch of 12 production helicopters, designated as the ''HU2K-1''. Under the 1962 United States Tri-Service aircraft designation system, the HU2K was redesignated H-2, the HU2K-1 becoming the UH-2A. Beyond the U.S. Navy, the company had also made efforts to acquire other customers for export sales, in particular the Royal Canadian Navy; however, the initi ...

HC-3 Insignia
Hemicholinium-3 (HC3), also known as hemicholine, is a drug which blocks the reuptake of choline by the high-affinity choline transporter (ChT; encoded in humans by the gene ''SLC5A7'') at the presynapse. The reuptake of choline is the rate-limiting step in the synthesis of acetylcholine; hence, hemicholinium-3 decreases the synthesis of acetylcholine. It is therefore classified as an indirect acetylcholine antagonist. Acetylcholine is synthesized from choline and a donated acetyl group from acetyl-CoA, by the action of choline acetyltransferase (ChAT). Thus, decreasing the amount of choline available to a neuron will decrease the amount of acetylcholine produced. Neurons affected by hemicholinium-3 must rely on the transport of choline from the soma Soma may refer to: Businesses and brands * SOMA (architects), a New York–based firm of architects * Soma (company), a company that designs eco-friendly water filtration systems * SOMA Fabrications, a builder of bicycle ...

Sikorsky H-3 Sea King
The Sikorsky SH-3 Sea King (company designation S-61) is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was one of the first ASW rotorcraft to use turboshaft engines. The Sea King has its origins in efforts by the United States Navy to counter the growing threat of Soviet submarines during the 1950s. Accordingly, the helicopter was specifically developed to deliver a capable ASW platform; in particular, it combined the roles of ''hunter'' and ''killer'', which had previously been carried out by two separate helicopters. The Sea King was initially designated ''HSS-2'', which was intended to imply a level of commonality to the earlier ''HSS-1''; it was subsequently redesignated as the ''SH-3A'' during the early 1960s. Introduced to service in 1961, it was operated by the United States Navy as a key ASW and utility asset for several decades prior to being replaced by the non-amphibious Sikorsky SH- ...
