Silver Bird Bomber
Air superiority was one of the most important factors in the winning of the war. Being able to rain destruction down on your foes from the clouds completely changed the way we fought, and both sides worked tirelessly to develop new means of attack. One German concept that never saw active duty was the Silbervogel, or Silver Bird bomber.
Eschewing traditional means of liftoff, the Silver Bird was accelerated to up to 1200 miles per hour by means of a rail-mounted rocket sled. After launch, the bomber would rise above the stratosphere and glide halfway around the world to deliver a nuclear payload to America soil – an impossibility for current weapons of the era. Thankfully, the Germans could never get it functioning correctly and the project was scrapped.
