  • Model: MC K-142
  • Manufactured by: Madcow Rocketry

4" in diameter, the Madcow Rocketry Little John is a fun-to-fly military sport-scale rocket. 

The Little John was a free flight artillery rocket designed to deliver the explosive power of heavy artillery. It could carry either nuclear or conventional warheads. Designed primarily for use in airborne assault operations, the highly mobile Little John rocket system complemented the heavier, self-propelled Honest John systems. The Little John reached the field in November 1961 and remained in the Army inventory until August 1969.

Recommended for experienced high-power rocketeers.
