FSX Republic F-105D Thunderchief (Thud). This is AlphaSim's F-105D modified for Flight Simulator X. The F-105 evolved from a project that began in 1951 by Republic Aviation to develop a supersonic tactical fighter-bomber to replace the F-84Fs. The prototype first flew on October 22, 1955, but the first production aircraft, the F-105B, was not delivered to the USAF until 1958. The F-105D all-weather strike fighter and the two-place F-105F dual-purpose trainer-fighter also were built before the F105 production (833 aircraft) ended in 1964. Package includes effects and a updated panel. Textures and FSX updates by Mark Rooks of RSDG Aircraft.
