Republic F-84F Thunderstreak and RF-84F Thunderflash by Charles Stafrace

Fraught with engine and aerodynamic teething problems that resulted in its missing the Korean War for which it was intended, the F-84F Thunderstreak, initially seen as languishing in the shadow of the more well-known and proven F-86 Sabre, matured to become a formidable fighter-bomber that served not only with the USAF's Tactical and Strategic Air Commands, but also with numerous European air forces for many of which it also offered the first experience in swept wing jet fighter operation. It provided a much-needed deterrent during the critical early years of the Cold War and the 1960s, especially with NATO air forces, where it normally replaced its straight-wing predecessor, the F-84 Thunderjet. No fewer than 2,711 examples of the Thunderstreak were built, so that for a time it was the fighter most in widespread use in Europe, becoming the backbone of the Alliance's combat element. In contrast, its service with the USAF was rather short-lived when newer fighters such as the F-100 Super Sabre and F-4 Phantom with superior and supersonic performance supplanted it in service. However, with the outbreak of the Vietnam War, when these modern fighters and the USAF's other more valuable combat aircraft were deployed to Southeast Asia, the USAF recalled the Thunderstreak for another spell of frontline service in defence of mainland United States.
