Scout X-2M was an American expendable launch system which was flown three times between May 1962 and April 1963.
It was a four-stage rocket, based on the earlier Scout X-2, but with an MG-18 upper stage instead of the Altair used on the X-2.
The first Scout X-2M was launched 24 May 1962, carrying P35-1, but failed to reach orbit.
The second flight, launched at 11:44 GMT on 23 August, was the only successful launch to be made by an X-2M, placing P35-2 into low Earth orbit.
The final launch, with P35-4 occurred on 26 April 1963, and like the first flight, it failed to reach orbit.
