The “B” variant of the Republic F-105 Thunderchief was the initial production version and became operational in May 1958 replacing the F-84 Thunderjet. On December 11, 1959 an F-105B set a world speed record of 1,216.48 mph over a 62 mile course. The F-105B never saw combat and only 75 were produced before the all-weather “D” variant became available in 1964. The F-105Bs were transferred to ANG and AFRES units with their last flight in 1981 when they were sent to be scrapped. At least five aircraft were spared and sent to museums.

On May 26, 1958 the first F-105 received by 335th Fighter-Day Squadron, 4th Fighter- Day Wing was the one and only F-105B-6RE built and was serial 54-111. It was considered the first F-105 delivered to an operational unit. Their job was to put the Thunderchief through its paces and find any deficiencies, which they did. On July 1, 1958 the unit was renamed the 4th TFW and the 335th became the 335th TFS. In early 1964 the 4th TFW transitioned to the F-105D/F.
