Background<\/h3>\n

In 1951 the US Army Chemical Corps and Ordnance Corps initiated a joint program to develop a 115mm chemical rocket. The US Army Ordnance Corps designed the 115mm T238 and launcher in 1957 to provide the army a means to attack large area targets with chemical agents.<\/p>\n

Artillery and mortars are for small area targets; and due to different spin stabilities weapons intended for explosives are not ideal for chemical delivery. The 115mm rocket was subsequently accepted as the M55 rocket with M91 launcher.<\/p>\n

Produced from 1959\u20131965, the M55s were manufactured at Newport Army Ammunition Plant and tested at Aberdeen Proving Ground.<\/p>\n

The Army produced unitary warheads filled with Sarin (GB) and VX nerve agents for the M55.<\/p>\n
