U.S. MGM-31A Pershing IA Missile. . In 1969, the Pershing IA Missile System was fielded as an upgrade of the existing Pershing I Battlefield Support Missile. The improved version utilized the existing missile; however, it was transported in an improved semi-trailer that carried erector-launcher, the missile and warhead. The erector-launcher trailer was towed by a M757 5-ton tractor. Other improvements included upgrading the automatic countdown procedures, semi-automated survey laying procedures and the incorporation of a sequential launch adapter which allowed rapid sequential firing of three missiles from one command station. The warhead is nuclear and accuracy is within a radius of 1200 ft as with the Pershing I. The Martin Corporation produced 129 launchers and 754 missiles which includes the Pershing I Missile. With the Pershing 1A, the number of launchers per battalion was increased from eight to thirty-six. The Pershing IA replaced the Pershing I in four US Army battalions and two wings of the German Air Force. The Pershing IA Missile system was removed from service with the adoption of the Intermediate Nuclear Forces Treaty between the United States and the Soviet Union in 1991. This treaty banned intermediate missile systems with ranges between 300 and 3,400 miles (500 to 5,500 km)., Length - 34 ft. - 10.5 m , Weight - 10,000 lbs. - 4,464 kg , Range - 100 to 460 miles - 162 to 740 km , Warhead - 60 to 400 kT Nuclear , CCN# 127072, 120073
