The Republic F-105 Thunderchief could go fast — it had a top speed of 1,390 miles per hour. But this “fighter” was, in reality, a powerful tactical bomber. But despite being designed to put bombs on land targets, the F-105 proved to be a deadly adversary to those who attacked from the sky — it was a rare bird; it was a bomber that could kill a fighter.
The F-105‘s design process started in 1950 as the intended replacement for the F-84F Thunderstreak, a plane that hadn’t yet made its first flight. The YF-105A prototype first flew in 1955 and was soon followed by the first production version, the F-105B. However, the F-105B was quickly deemed out-dated, as it could only operate in daylight and in good weather.
A look at the wide variety of weapons the F-105 Thunderchief could carry into battle.
The main weapon of the F-105 was supposed to be a B28 or B43 “special store” — a nuclear bomb. The later B57 and B61 nukes were later made options for the plane as well. Thankfully, these were never used in anger. But what did get use was the F-105’s ability to carry up to 14,000 pounds of ordnance — not to mention AIM-9 Sidewinders and a M61 Vulcan gun with 1,028 rounds of ammo.
With the onset of newer models, specifically the F-105D, the Thunderchief became a lethal plane in any weather condition, day or night. The F-105D was the workhorse during the early days of the Vietnam War. The plane successfully pummeled land targets, like the Paul Doumer bridge, while excelling in air-to-air combat. The F-105 scored 27.5 kills in the skies.
The F-105G Wild Weasel version of the Thunderchief was used to kill or suppress enemy surface-to-air missile sites.
The F-105F, intended as a combat trainer, instead became the basis for the most notable Wild Weasel of the Vietnam War – the F-105G. One Wild Weasel pilot, Leo Thorsness, would earn the Medal of Honor in the F-105 for taking on North Vietnamese MiGs during an effort to rescue a downed air crew.
The F-105 stayed in service until 1984, marking nearly three decades of service. Learn more about this lethal multirole fighter in the video below.
