The A-7E Corsair II attack aircraft entered service with the Royal Thai Navy in the mid-1990s. These aircraft were purchased from the United States after being retired from the US Navy. The primary motivation for the acquisition was to modernize the Royal Thai Navy's strike capabilities and provide the fleet with multirole aviation in support of land and maritime operations. In addition to the A-7Es, Thailand also received two-seat TA-7E trainer variants. The aircraft transferred to Thailand were assigned to the 104th Squadron based at U-Tapao Royal Thai Navy Airfield. Before entering service, the fighters underwent the necessary adaptations to operate in Thailand's climate and infrastructure. However, their integration into the Thai Navy's fleet faced challenges related to maintenance complexity, personnel training, and limited resources. Thus, despite initial expectations, the A-7Es did not become a fully integrated and long-term part of the Thai armed forces, remaining in service for just over 10 years. On July 20, 2007, it was officially announced that these aircraft had been decommissioned and placed in storage. The A-7Es in the Thai Navy became the last instance of this model's use outside of the United States.

Introduced in Update "Storm Warning", the Thai A-7E has an extensive arsenal of suspended weapons, allowing it to provide air support to allied armored vehicles, striking with various unguided weapons as well as precision-guided munitions. Like the American version, the aircraft is equipped with the LANA FLIR targeting system and AGM-62A Walleye I ER television-guided bombs, which allow for faster and more precise destruction of enemy armored vehicles. However, the A-7E has mediocre flight performance, making it an easy target for enemy surface-to-air missile (SAM) systems and aircraft. For self-defense against enemy aircraft, the A-7E can be armed with two AIM-9G air-to-air missiles.
