The howitzer was fired from 3-point suspension, with the trails spread and the carriage resting upon an integral firing jack, the wheels being clear of the ground. The relatively moderate weight of the materiel added to its maneuverability and its ease of transport. When limbered to a prime mover, the materiel could be drawn at speeds at up to 30 miles per hour on improved roads. The wheels were equipped with large pneumatic tires for high-speed transport. In traveling position the trails were locked together by a toggle type clamping mechanism and were limbered directly to the prime mover. The 155mm Howitzer Carriage M1 was of the single axle, 2-wheel, split-trail type. They have been following the advance of the infantry and are now setting up this new position.", "Troops of a field artillery battery emplace a 155mm howitzer in France. The howitzer could also fire smoke or white phosphorus shells. It throws its projectiles at a muzzle velocity of 1,850 feet per second to a maximum range of approximately 16,500 yards. The rate of fire in rapid bursts is 3 rounds per howitzer per minute for prolonged firing, 1 round per howitzer per minute. The M1 155mm howitzer typically fired 80% or more HE (high-explosive) shells. The primers were placed in the breech of the gun for firing. Fuses were placed in the base of the projectile after a ring used for shipping was removed. The 155 used "separate loading" ammunition comprised of four components: a projectile, a separate bagged propellant charge, a fuse and a primer. The propelling charge contained individual bags of powder, which could be reduced to adjust for range of fire. The projectiles weighed 95lb each. This meant that two separate movements were necessary to open the breech, versus the single movement of the 'steep cone' mechanism that simultaneously rotated and withdrew the breech.Īmerican 155-mm howitzer M1 firing at German troops in the area of Cherbourg Uniquely, it was the sole 'slow-cone' interrupted screw mechanism to enter service after 1920. The howitzer itself differed from the older model by a lengthened barrel of twenty calibers and a new breech mechanism.
This was completed by May 15th, 1941 when the Howitzer M1 on the Carriage M1 was standardized. Consequently, development began anew with a carriage designed to be used for the 155-mm Howitzer.
