@description = The legendary Orion Nuclear Pulse drive, utilizing nuclear shaped charges fired at a heavy pusher plate to achieve incredibly high thrust and performance. This is one of the later proposals, presented to the air force in the mid-1960s as a downscaled, lower performance version of the original 4000 ton Orion space battleship proposal. This would allow it to be carried to a suborbital trajectory by a Saturn V or other large rocket before starting its engines, reducing the risks involved. It was also offered to NASA to carry an 8-man crew to Mars and back in a matter of months. Although subscale tests were performed using conventional explosives, and full-size nuclear pulse units were allegedly testing, the political implications of developing such a drive and the Nuclear Test Ban treaty resulted in it's cancellation around 1965. Atmospheric use inadvisable..
