American nuclear orbital launch vehicle. In the first half of the 1960's it was planned to make suborbital tests of nuclear propulsion for upper stages using a Saturn IB first stage to boost a Rover-reactor powered second stage on a suborbital trajectory. The second stage would impact the Atlantic Ocean down range from Cape Canaveral.
