After the end of the Greek Civil War in 1949, the Royal Hellenic Air Force was in need of modernisation, primarily due to threats from communist neighbours. Because of this, Greece joined NATO in 1952 and received much-needed military aid. Among these were 200 Republic F-84G Thunderjets, which were delivered from 1952–1955 and became the RHAF's first jet fighters. The F-84G would serve with the RHAF until 1960, when it was replaced by the Canadair Sabre 2.

The Greek F-84G was introduced in Update 2.59 "Sky Odyssey" as part of the Israeli tree and is functionally identical to its American counterpart. Like other early jet fighters, the F-84G's modus operandi is maintaining its speed. The aircraft is at its best when flying fast and at its worst while slow; therefore, knowing when to engage and disengage from a dogfight is important. Other than aerial duties, the Thunderjet is also capable of providing air support using a variety of heavy payloads.
