However, MAGs are shore-based (with sea-based capability) and may contain any combination of aircraft squadrons and aviation support units.
As there were just too many carriers and the symbols were hard to remember or to describe over the radio, a single or double letter system was introduced in July 1945.
The following identifications are known:[5] Shangri-La is known to have had her Lightning Bolt on the flight deck forward and aft replaced by her air group identification letter "Z", as the slight remaining Lightning Bolt can be seen painted on the deck beneath the Z on the victory photos of the carrier.
[6] On 15 November 1946, to correct the results of demobilization which had left squadron numbers all out of sequence, sweeping changes were made in air unit designations.
[8][note 1] The CAG was expected to personally lead all major strike operations, co-ordinating the attacks of the carrier's fighter, bomber, and torpedo planes in combat.
[10] In 1963 when Carrier Air Groups were retitled Wings, the commander retained the legacy title of "CAG" which continues to this day.
Initially filled by a junior captain who had recently completed his (or her) squadron command tour, the position is now filled by a senior captain who "fleets up" and replaces the out-going CAG after about 18 months for a total DCAG-CAG tour duration of 36 months.
[12] A modern carrier air wing has a small command staff consisting of 16–20 officers and approximately 20 enlisted personnel.
CAGs are typically qualified to fly at least two types of aircraft in the Carrier Air Wing inventory.
New to the air wings in the Cold War period after Korea and just prior to Vietnam were specialized squadrons or detachments of aircraft for heavy attack/nuclear strike (VAH), photographic reconnaissance (VAP/VFP, RVAH), airborne early warning (VAW), all-weather medium attack (VA), advanced twin-seat fighters (VF), electronic countermeasures (VAQ), and rescue and plane guard helicopters (HU).
The VS and HS squadrons of the former Anti-Submarine Air Groups joined the Carrier Air Wings and the HS squadrons, in addition to their Anti-Submarine role, assumed the search and rescue (SAR) and plane guard roles formerly filled by the HC detachments.
The North American RA-5C Vigilante was also phased out in January 1980, replaced by F-14 Tomcats with Tactical Air Reconnaissance Pods (TARPS).
From 1991 to 1995, several Type/Model/Series (T/M/S) aircraft were phased out of the active inventory (e.g., Regular Navy and Naval Air Reserve), to include the RF-8G Crusader, the A-7E Corsair II, ES-3A Shadow, SH-3H Sea King and the A-6E and KA-6D Intruder.
While some of these retirements were due to obsolescence (RF-8G) or succession by newer aircraft (A-7Es replaced by F/A-18s), others were due strictly to post-Cold War perceived "Peace Dividend" budget measures on the part of certain Secretaries of Defense and the U.S. Congress (e.g., A-6 Intruder), with aircraft that still had useful remaining life being prematurely relegated to retirement.
Other T/M/S aircraft saw the number of operational squadrons significantly reduced (e.g., F-14 Tomcat, E-2 Hawkeye) for similar budgetary reasons.
In 1992, a program named CV Integration began with Marine Corps EA-6B and F-18 squadrons augmenting Carrier Airwings due to the shortage of EA-6Bs and F-18 aircraft in the inventory.
In 1996, the last Marine Corps EA-6B squadron completed their CV Integration aboard the USS America which was making its final cruise.
Today's air wing composition is designed to allow for broad striking power hundreds of miles from the carrier's position, while providing defense in depth of the battle group through early warning and detection of airborne, surface and subsurface targets.
The "A" or "N" is followed by a letter that uniquely identifies the air wing (e.g., CVW-1 aircraft, part of the Atlantic Fleet, have a tail code of "AB").
