General
ROCKET, 762-MM: M31 series, is a large caliber, field artillery, free-flight, fin-stabilized rocket designed to be fired from a rail-type launcher against terrestrial targets. The assemblies and components required to assemble one complete 762-mm rocket with a high-explosive warhead are stored, issued, and shipped in three containers: a rocket motor, a loaded warhead assembly, and fins. The rocket motor M31A1 or M3A1C is that portion of the rocket which houses the propellant, the spin rockets, and the ignition system. Four fins are attached to the fin base fittings which are located 90° apart on the nozzle of the rocket motor. The warhead assembly for the 762-mm rocket is the foremast portion of the complete round, serves as a housing for the warhead and necessary fuzing, and provides a streamlined surface to improve the ballistic trajectory of the rocket.
ROCKET, 762-MIILLIMETER: M31A1, consists of rocket motor M3A1, 762-mm rocket flash-smoke warhead assembly M1A2 or 762-mm rocket flash-smoke warhead assembly XM38E1 or 762-mm rocket high-explosive warhead assembly M1A2, and 762-mm rocket fin M136A1 or 762-mm rocket fin M136A2 or 762-mm rocket fin M136A2B1.
ROCKET, 762-MILLIMETER: M31A1C, consists of rocket motor MA1C, 762-mm rocket flash-smoke warhead assembly M1A2 or 762-mm rocket flash-smoke warhead assembly XM38E1 or 762-mm rocket high-explosive warhead assembly M1A2, and 762-mm rocket fin M136A1 or 762-mm rocket fin M136A2 or 762-mm rocket fin M136A2B1.
ROCKET, 762-MILLIMETER: M31A2, consists of rocket motor M3A2, 762-mm rocket flash-smoke warhead assembly M1A2 or 762-mm rocket flash-smoke warhead assembly XM38E1 or 762-mm rocket high-explosive warhead assembly M1A2, and 762-mm rocket fin M136A1 or 762-mm rocket fin M136A2 or 762-mm rocket fin M136A2B1. |
