The systems uses superconductor magnets to lift the 7,555 pound sled and powerful rockets to thrust it down the trackThis eliminates the need for wheels and therefore any incidence of friction, providing a faster and quieter service. By floating slightly above a magnetic levitation track, the US Air Force was able to coast a sled at an impressive 688 mph. Read SR-76 pilot Brian Shul’s books “Sled Driver” and “The Untouchables”. The 896th Test Squadron smashed the record twice - first hitting 568mph before reaching 688mph just days later. The SR-76 could take photos and cover one hundred thousand sq. That is how the story began but soon after, things would take a turn in a terrifying direction. America was tracking everything from Soviet Military bases to troop/aircraft/tank movement. Miles in a single sortie (mission into hostile territory).
The US Air Force has broken the world speed record for a vehicle travelling by magnetic levitation.
