History of the T19 105mm Howitzer Motor Vehicle Mount (HMC)
The "105mm Howitzer Motor Carriage T19" (105mm HMC T19) is another offshoot of the ubiquitous long-range American M3 halftrack family. This particular variant was developed to fulfill the role of a self-propelled gun, with a 105mm M2A1 field howitzer mounted on a bracket in the center section of the M3 half-track hull. The cab is carried over from the original, as is the classic chassis, configuration and general silhouette. Due to the size of the guns carried, only eight 105mm shells were loaded on board, giving the T19 a limited tactical range on the battlefield.
However, it played an important role in supplying self-propelled guns to the very unstable front lines of the WWII campaign.
The M2A1 howitzer was designed from the legendary Rock Island Armory, which borders Davenport, Iowa, and Rock Island, Illinois. It entered production in 1941 and production extended to 1953 to ensure that the gun would end in good, healthy service. The weapon system weighs nearly 5,000 pounds and measures 19 feet 6 inches in length.
The breech is arranged in a horizontal block, and the recoil is handled by a hydropneumatic system. Altitude measurement ranges from -5 to +66 degrees, up to 46 degrees on both sides of the wire. The maximum range is seven miles.
The weapon proved popular with U.S. allies during and after World War II.
Generally speaking, vehicles like the T19 give way to appropriate dedicated platforms, such as the M7 Priest SPA, which has been a success since 1942. These are built on the chassis of the M3 Lee medium tank.
