The obsolescence of the AD/A-1 Skyraider attack aircraft led to the search for a new plane able to satisfy both US Navy (USN) and US Marine Corps (USMC) requirements. Aside from the type of engine, the new plane was to be capable of all-weather operations. Grumman was one of eleven companies that sent their designs for selection, and Grumman's design was selected in January 1958 as the YA2F-1. Following development and testing, the YA2F-1 was accepted into the US Navy in February 1963 as the A-6 Intruder. Following experiences in the Vietnam War, the A-6 went through multiple variants featuring improvements or for specialized roles. The A-6E was introduced in December 1972 with better navigation, attack, and radar equipment. It featured another enhancement in 1979 with the Target Recognition and Attack Multi-sensors (TRAM) system, which enabled better targeting abilities for improved munition accuracy. The A-6E Intruder and its variants continued serving the US Navy in most combat operations from the Vietnam War onwards, including the 1991 Gulf War. All Intruders were retired by February 1997.

Introduced in Update "Apex Predators", the premium A-6E TRAM is one of the more unique aircraft in the game as it does not come with any native weapons. The weapon it brings into the battle is dependent on five hard points that players are able to customize. The assortment of weapons is quite remarkable, with smart weapons like guided bombs not needing a targeting pod due to the TRAM system installed in the aircraft. That said, the A-6E TRAM is subsonic-only, so it cannot get to the battlefield quickly and falls closer to the category of A-10s and Su-25s. However, if the battlefield calls for very specific loadout requirements, the A-6E can provide that kind of flexibility to bring only what is essential to the needs of the battlefield.
