The F-105B entered service in the summer of 1958. It was nicknamed the โ€˜Thudโ€™ after the character Chief Thunderthud from the โ€œHowdy Doodyโ€ TV series.ย 

It carried a 20mm M61 Gatling-type cannon. The plane operated extensively in Operation Rolling Thunder in the air campaign against North Vietnam.ย 

Convair F-106 Delta Dart

Another plane in the Century Series is the Convair F-106 Delta Dart, the final development of the USAFโ€™s interceptor program in the early 1950s.ย 

The F-106 was designed without a gun or even a way to carry bombs. Its main armament was missiles that were carried in an internal weapons bay for clean supersonic flight.ย
