Road Test of H1572 Kit for 155MM Projectile (M753 System)

The U.S. Army Defense Ammunition Center and School (USADACS), Validation Engineering Division (SMCAC-DEV), was tasked by the U.S. Army Armament, Munitions and Chemical Command (AMCCOM), AMSMC-TMD, to conduct the necessary transportability tests to develop tiedown procedures securing the H1572 kit, package 2 of 2 for the M753 projectile, in the 2 1/2-ton cargo truck and 22 1/2-ton M871 semitrailer. The H1572 kit was secured in each vehicle in three separate configurations and then tested over the USADACS road hazard course. The configurations consisted of a longitudinal position secured with two 5,000-pound web straps, a lateral position secured with two 5,000-pound web straps, and a lateral position secured with one 5,000-pound web strap. Results from the road hazard testing indicated that the two web straps were sufficient to hold the H1572 kit in the longitudinal orientation, and one web strap was sufficient to hold the H1572 kit in the lateral orientation.
