Scout X-2M was an Americanexpendable launch system which was flown three times between May 1962 and April 1963. It was a four-stage rocket, based on the earlierScout X-2, but with anMG-18 upper stage instead of theAltair used on the X-2. It was a member of theScout family of rockets.
The Scout X-2 was an all-solid rocket, with anAlgol 1D first stage, aCastor 1A second stage, anAntares 2A third stage, and an MG-18 fourth stage. It was launched fromLaunch Complex D atPoint Arguello, and was used for the launch ofP-35 weather satellites.
The first Scout X-2M was launched 24 May 1962, carryingP35-1, 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, placingP35-2 intolow Earth orbit. The final launch, withP35-4 occurred on 26 April 1963, and like the first flight, it failed to reach orbit.
