The "G-1 Flight Jacket" is the commonly accepted name for the fur-lined-collar flight jacket used by Naval Aviators in the United States Navy, Marine Corps, and Coast Guard. [1] It began with a completely new jacket specification on 28-Mar-1940, the M-422, and has been issued to this day; now in the current MIL-DTL-7823F iteration.
The G-1 remains used by officer and enlisted aviation personnel on flying status in the U.S. Navy, U.S. Marine Corps and U.S. Coast Guard (i.e., Naval Aviator, Naval Flight Officer, Naval Flight Surgeon, Naval Aircrewman, etc.) and was featured as the leather flight jacket worn by Tom Cruise in the film Top Gun .
The history of the "G-1" can be split into four parts, based upon the specification family: (1) M-422/M-422a, (2) AN-J-3/AN-J-3a, (3) 55-J-14, and (4) 7823.
The M-422 was constructed of chocolate brown chrome tanned goatskin, a fairly uniform color that has continued throughout all iterations, unlike the Air Force A-2 jacket in seal brown leather that was interpreted from being a light russet to dark brown color. The M-422 used a mouton collar, bi-swing back, rayon lining and silk thread throughout. [2] Linen thread was used on the buttons beginning with the M-422a on 1-Oct-1940. [3] The use of a different, stronger, "button thread" began with the M-422a and continues today.
The AN-J-3 specification, using illustrative drawing AN6552, was a joint Army-Navy effort, being an update to the M-422a specification on 15-Apr-1943 with a leather instead of mouton collar. [4] A military-issued AN-J-3 has not been located and the reasons are unknown. The AN-J-3 was quickly replaced by the mouton collared AN-J-3a on 6-Oct-1943 with an updated AN6552 illustrative drawing (either the Spec or Drawing number can be on the label). [5] The US Navy considered the M-422a and AN-J-3a to be equivalent and both are listed by the same stock number in the Dec 1943 Aviation Supply Office catalog. The first jacket called a "G-1", internally, was the AN-J-3a as described in an Oct 1943 U.S. Aeronautical Board document. [6]
The 55-J-14 specification saw the Navy move away from the joint Army-Navy AN-J-3a, but the Navy never made a 55-J-14 jacket based upon the original 31-Oct-1947 specification. The original 55-J-14 specification called for a shearling collar and this was changed back to the normal mouton collar in a 10-May-1949 update, with all 55-J-14 jackets made to the later 10-May-1949 specification. [7] Interestingly, the last AN-J-3a contract, N383s-1035, was made in early 1949 though the reasons are unknown. The 55-J-14 was the first jacket to have "G-1 Flight Jacket" on the label.
The MIL-J-7823 specification began on 21-Nov-1951, with numerous iterations to follow. [8] The nylon lining has been used throughout, with the permitted use of synthetic mouton (MIL-M-6590) beginning with MIL-J-7823D [9] and cowhide (KK-L-162) added beginning with MIL-J-7823E Amendment #3. [10] Unlike the original contracts that provided guidelines for construction, when clear manufacturer-to-manufacturer differences were seen, the current specifications go into great detail to ensure consistency across all manufacturers. [11]
After the Second World War, it became common for G-1 jackets to be adorned with patches earned during a pilot's career. Patches include types of aircraft flown, milestones in carrier landings or total flying hours, and deployments or cruises carried out on certain ships.
For a very brief period from 1979 until early 1981, issuance of the G-1 to new USN, USMC, and USCG flight crew personnel (i.e., officer flight students and newly designated enlisted Naval Aircrewman) was discontinued as a budgetary economy action, with those personnel being issued summer weight green Nomex flight jackets identical to those issued to their U.S. Air Force counterparts. Replacement of worn-out G-1 jackets for extant Naval Aviation personnel was also discontinued during this period. This action was reversed by Secretary of the Navy action in early 1981, and those USN, USMC, and USCG flight-crew personnel who had not received G-1 jackets were issued one retroactively.
Modifications to USN, USMC, and USCG uniform regulations in the 1990s reduced the type and number of permissible insignia on the G-1, but concurrently permitted wear of the G-1 jacket off base with service uniforms.
Commercial versions of the jacket have been available on the consumer market. Official military suppliers which also sold similar spec jackets to the public include Cockpit USA, Cooper Sportswear, Orchard M/C, Brill Bros., Schott, and Excelled. After the success of the 1986 film Top Gun , shopping-mall leather stores carried a variety of G-1 variants. These are new production and come in goatskin and cowhide varieties stamped USN, USCG, or USMC. Jackets are offered by many companies for the civilian market, including US Authentic Mfg. Co., Lost Worlds, Gibson and Barnes, Eastman, US Wings and Bill Kelso Mfg.
The Jacket Specification [Implementation Date] are listed below in chronological order, then with known manufacturing companies followed by the contract number. Note for the M-422a contracts that The Bureau of Supplies & Accounts changed their identifying prefix in March 1942 from NOs to NXs, though when that change filtered down to the all the labels is unclear, making some contracts appear as either NOs-# or NXs-# on the label for the same contract. This occurred again when the prefix went from NXs-# to NXsa-# in Jan 1943. [12]

Coaxial cable, or coax, is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ; many coaxial cables also have a protective outer sheath or jacket. The term coaxial refers to the inner conductor and the outer shield sharing a geometric axis.
The BNC connector is a miniature quick-connect/disconnect radio-frequency connector for coaxial cable. It was introduced on military radio equipment in the 1940s, and has since become widely used in radio systems and as a common type of video connector. It has a twist-to-lock design, where two lugs on the female connector engage slots in the shell of the male one.
JOVIAL is a high-level programming language based on ALGOL 58, specialized for developing embedded systems. It was a major system programming language through the 1960s and 1970s.
The Grumman JF "Duck" was an American single-engine amphibious biplane built by Grumman for the United States Navy during the 1930s. The J2F Duck was an improved version of the JF, with its main difference being a longer float.
A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the U.S. Department of Defense.
The M1895 Lee Navy was a straight-pull magazine rifle adopted in limited numbers by the U.S. Navy and Marine Corps in 1895 as a first-line infantry rifle. The Navy's official designation for the Lee Straight-Pull rifle was the "Lee Rifle, Model of 1895, caliber 6-mm" but the weapon is also largely known by other names, such as the "Winchester-Lee rifle", "Lee Model 1895", "6mm Lee Navy", and "Lee Rifle, Model of 1895".
JP-8, or JP8, is a jet fuel, specified and used widely by the US military. It is specified by MIL-DTL-83133 and British Defence Standard 91-87, and similar to commercial aviation's Jet A-1, but with the addition of corrosion inhibitor and anti-icing additives.
The Type A-2 leather flight jacket is an American military flight jacket closely associated with World War II U.S. Army Air Forces pilots, navigators and bombardiers, who often decorated their jackets with squadron patches and elaborate artwork painted on the back.
The MA-1 bomber jacket is an American military jacket which was developed in the 1950s. The MA-1 and its predecessor, the B-15 flight jacket, were originally developed and needed at that time because the characteristics of the new jet aircraft created new requirements for pilot performance, safety, and comfort.
Electrical or fiber-optic connectors used by U.S. Department of Defense were originally developed in the 1930s for severe aeronautical and tactical service applications, and the Type "AN" (Army-Navy) series set the standard for modern military circular connectors. These connectors, and their evolutionary derivatives, are often called Military Standard, "MIL-STD", or (informally) "MIL-SPEC" or sometimes "MS" connectors. They are now used in aerospace, industrial, marine, and even automotive commercial applications.
MIL-DTL-5015 is a United States Military Standard which covers heavy-duty circular electrical connectors with soldered or crimped contacts. They are used for both digital and analog signals, as well as power distribution, and are common in various fields, including defense, aerospace, and industrial machinery. The connectors are particularly versatile and reliable, and due to their prevalence, relatively inexpensive.
The Cretaceous Thermal Maximum (CTM), also known as Cretaceous Thermal Optimum, was a period of climatic warming that reached its peak approximately 90 million years ago (90 Ma) during the Turonian age of the Late Cretaceous epoch. The CTM is notable for its dramatic increase in global temperatures characterized by high carbon dioxide levels.
