Tail codes are markings usually on the vertical stabilizer of U.S. military aircraft that help identify the aircraft's unit and/or base assignment. This is not the same as the serial number, bureau number, or aircraft registration which provide unique aircraft identification.
Since 1993, the U.S. Air Force (USAF), Air Force Reserve, and Air National Guard (ANG), except Air Mobility Command (AMC) aircraft, utilize this format in all tail codes: two large letters, followed by two digits printed in a smaller text size, followed by three more digits printed in a larger text size.
The first two letters identify the home base, or in some organizations, a historic legacy, such as "FF" ("First Fighter") for the 1st Fighter Wing [1] or "WP" ("Wolf Pack") for the 8th Fighter Wing. ANG units usually use the two-letter state/territorial USPS mailing abbreviation as a tail code, though there are exceptions, such as the 110th Airlift Wing using "BC" ("Battle Creek") instead of the "MI" used for other Michigan Air National Guard units. The small digits indicate the fiscal year (FY) the aircraft was ordered. The large digits are the last three digits of the aircraft's serial number. [2] [3]
All aircraft assigned to a unit, or in the case of ANG units, the entire state, use a common code. Typically, units of different commands co-located at the same base use different codes. For example, the 509th Bomb Wing at Whiteman AFB uses "WM" while the 442nd Fighter Wing of the Air Force Reserve at the same base uses "KC."
AMC aircraft do not use two-letter identification codes. [4] They have the name of the base written inside the tail flash and a five-digit number in which all digits are printed in the same size. In most cases, the first digit represents the last digit of the fiscal year, and the remaining digits identify the four-digit sequence number. In cases where more than 10,000 aircraft were ordered in a single year (1964, for example), the complete 5-digit sequence number - without FY identification - is used.
The U. S. Navy's aircraft visual identification system uses tail codes and modex to visually identify the aircraft's purpose and organization. Carrier air wing (CVW) tail codes denote which fleet the air wing belongs; A for Atlantic Fleet and N for Pacific Fleet. All squadrons display their CVW's tail code as follows, regardless of aircraft type:
Electronic Attack Squadrons (VAQ) of Electronic Attack Wing Pacific which are not assigned to a CVW but instead deploy to fixed land bases in support of joint tasking ("Expeditionary" VAQ Squadrons) use tail code NL.
Fleet Replacement Squadrons (FRS) for fixed wing carrier based aircraft use the CVW style tail code. Naval Air Force Pacific Fleet carrier based fixed wing aircraft FRS use tail code NJ and Naval Air Force Atlantic Fleet carrier based fixed wing aircraft FRSs display tail code AD. The FRS for carrier based helicopters do not follow this rule.
The US Navy Reserve's Tactical Support Wing (formerly Reserve Carrier Air Wing 20) uses tail code AF. NW was the tail code for Helicopter Wing Reserve which has been disestablished, but the two reserve helicopter squadrons which still exist continue to use that code even though the wing no longer exists.
Helicopter FRS and helicopter squadrons not assigned to CVW (except for reserve squadrons) and all land-based fixed-wing squadrons use two letter codes unique to each squadron. These codes are squadron specific and identify neither the squadron's wing nor base air station.
Training Command aircraft use a single-letter tail code which identifies the aircraft's training wing.
Search and rescue helicopters and light transport aircraft assigned to naval air stations or naval air facilities use a code consisting of a number (seven or eight), followed by a letter unique to each air station/facility.
The U.S. Marine Corps and U. S. Navy share the same system. USMC squadrons use two letter codes unique to each squadron. The codes are squadron specific and do not identify either the Marine Air Group (MAG) nor the Marine Air Wing (MAW) to which the squadron belongs nor the air station at which it is based. The exception is those squadrons assigned to a Navy Carrier Air Wing which use the Carrier Air Wing's tail code.
Light transport aircraft assigned to Marine Corps Air Stations use a two place tail code consisting of a number 5 followed by a letter unique to each Marine Corps Air Station.
Naval Air Station Lemoore or NAS Lemoore is a United States Navy base, located in Kings County and Fresno County, California, United States. Lemoore Station, a census-designated place, is located inside the base's borders.
Naval Air Station (NAS) Oceana or NAS Oceana is a United States Navy Naval Air Station located in Virginia Beach, Virginia.
A naval aviator is a commissioned officer or warrant officer qualified as a crewed aircraft pilot in the United States Navy or United States Marine Corps. United States Coast Guard crewed aircraft pilots are officially designated as "Coast Guard aviators", although they complete the same undergraduate flight training as Navy and Marine Corps crewed aircraft pilots, and are awarded the same aviation breast insignia.
A carrier air wing is an operational naval aviation organization composed of several aircraft squadrons and detachments of various types of fixed-wing and rotary-wing aircraft. Organized, equipped and trained to conduct modern US Navy carrier air operations while embarked aboard aircraft carriers, the various squadrons in an air wing have different but complementary missions, and provide most of the striking power and electronic warfare capabilities of a carrier battle group (CVBG). While the CVBG term is still used by other nations, the CVBG in US parlance is now known as a carrier strike group (CSG).
Fighter Squadron 124 or VF-124Gunfighters was a fleet replacement squadron (FRS) of the United States Navy. Originally established on 16 August 1948 as VF-53, it was redesignated VF-124 at NAS Moffett Field on 11 April 1958 due to a need for an increased number of flight training squadrons, itself necessary because of introduction of swept wing fighters into Navy service. In 1961, the squadron relocated to NAS Miramar, California, which would become the U.S. Pacific Fleet's Master Jet Base for fighter aircraft.
Strike Fighter Squadron 115 (VFA-115) is known as the "Eagles", callsign "Talon", a United States Navy F/A-18E Super Hornet strike fighter squadron stationed at Marine Corps Air Station Iwakuni. Their tail code is NF. It was established as Torpedo Squadron VT-11 on 10 October 1942, redesignated VA-12A on 15 November 1946, VA-115 on 15 July 1948, then finally VFA-115.
Strike Fighter Squadron 195 (VFA-195), also known as the "Dambusters", is a United States Navy F/A-18E Super Hornet fighter squadron stationed at Marine Corps Air Station Iwakuni, Japan. They are a part of Carrier Air Wing Five (CVW-5) and their tail code is NF. Their radio callsign is "Chippy".
Strike Fighter Squadron 83 (VFA-83), also known as the "Rampagers", are a United States Navy F/A-18E Super Hornet fighter squadron stationed at Naval Air Station Oceana. They are a part of Carrier Air Wing 3, their tailcode is AC and their radio callsign is Ram.
Carrier Air Wing Fourteen (CVW-14), was a United States Navy aircraft carrier air wing based at Naval Air Station Lemoore, California.
Carrier Air Wing Seventeen (CVW-17), is a United States Navy aircraft carrier air wing based at Naval Air Station Lemoore, California. The air wing is attached to the aircraft carrier USS Nimitz.
Naval Air Station Cecil Field or NAS Cecil Field was a United States Navy air base, located in Duval County, Florida. Prior to October 1999, NAS Cecil Field was the largest military base in terms of acreage in the Jacksonville, Florida area.
Fighter Squadron Composite 111 (VFC-111), also known as the "Sun Downers", is a United States Navy Reserve adversary squadron based at Naval Air Station Key West, Florida. Currently, it operates Northrop F-5N/F Tiger-IIs, of which most are single-seater F-5Ns and one twin-seater F-5F, the "FrankenTiger".
Helicopter Sea Combat Squadron Four (HSC-4), also known as the Black Knights, is a multi-role combat helicopter squadron of the United States Navy based at Naval Air Station North Island which operates Sikorsky MH-60S Seahawk helicopters deployed aboard aircraft carriers. The squadron was originally established as HS-4 on 30 June 1952 at U.S. Naval Auxiliary Landing Field Imperial Beach with the Sikorsky HO3S-1 and was redesignated HSC-4 on March 29, 2012. It is currently assigned to Carrier Air Wing Two (CVW-2) which deploys aboard USS Carl Vinson (CVN-70).
A modex is a number that is part of the Aircraft Visual Identification System, along with the aircraft's tail code. It usually consists of two or three numbers that the Department of the Navy, U.S. Navy and U.S. Marine Corps use on aircraft to identify a squadron's mission and a specific aircraft within a squadron. These numbers are painted conspicuously on the aircraft's nose—or, on helicopters, sometimes on the aft portion of the fuselage or forward portion of the empennage. Modexes are also painted less conspicuously on other aircraft areas. Shore-based aviation units use either two-digit or three-digit modexes, while carrier-based units always use three digits.
A Fleet Replacement Squadron (FRS), is a unit of the United States Navy or Marine Corps that trains Naval Aviators, Naval Flight Officers (NFOs) and enlisted Naval Aircrewmen on the specific front-line aircraft they have been assigned to fly. Students, referred to as Replacement Pilots, Replacement Flight Officers or Replacement Aircrew are either newly winged aviators, aviators transitioning from one type aircraft to another, or aviators returning to the cockpit after a period of non-flying. After completing the training regimen, graduates are assigned to fleet squadrons. Additionally, FRSs are responsible for training aircraft mechanics, providing replacement aircraft for fleet squadron attrition, and standardizing maintenance and aircraft operations.
Fighter Squadron Composite 204 (VFC-204), also known as the "River Rattlers", is a United States Navy Reserve adversary squadron, slated to fly the F-5N/F Tiger II after having previously flown the F/A-18C/D Hornet. The squadron is based out of Naval Air Station Joint Reserve Base New Orleans, Louisiana, and is part of the U.S. Navy Reserve's Tactical Support Wing. Their radio callsign is "River" and their tail code is "AF".
Tail codes on the U.S. Navy aircraft are the markings that help to identify the aircraft's unit and/or base assignment. These codes comprise one or two letters or digits painted on both sides of the vertical stabilizer, on the top right and on the bottom left wings near the tip. Although located both on the vertical stabilizer and the wings from their inception in July 1945, these identification markings are commonly referred as tail codes. It is important to note that tail codes are meant to identify units and assignments, not individual aircraft. For all aircraft of the U.S. Navy and U.S. Marine Corps unique identification is provided by bureau numbers.
