The 1966 film “The Strength of SAC” showcases the weapons and the personnel of Strategic Air Command. The Boeing B-52 Stratofortress strategic bomber is featured prominently in the film, but this is a comprehensive look at SAC- from tankers and ground support personnel to strategic missiles and command posts on the ground and in the air. North American F-100 Super Sabres and Republic F-105 Thunderchiefs also appear in the film as do Boeing KC-135 Stratotankers. The film was uploaded to YouTube by PeriscopeFilm.
SAC was a wide-ranging command that utilized all sorts of systems to defend the country. B-52s flew thousands of radar bombing runs (simulating attacks) all over the nation during this period.
One way to score those simulated bomb runs was the Radar Bomb Scoring (RBS) train, dubbed the “RBS Express.” These trains, three of which were pieced together using Army rolling stock, consisted of 21 cars each and were seen wearing SAC badges on tracks near SAC bomb plots across the country and in Canada.
