Scout X-1A was an American sounding rocket which was flown in 1962.
The second, third and fourth stages were the same as those used on the Scout X-1; a Castor 1A, Antares 1A and Altair 1A respectively.
The fifth stage was the NOTS-17 solid rocket motor, which had been developed by the Naval Ordnance Test Station.
It flew from Launch Area 3 of the Wallops Flight Facility.
The flight carried an atmospheric re-entry experiment to an apogee of 214 kilometres (133 mi), and was successful.
