For a typical US 155 artillery round such as the M-107 normal cavity round, it has a kill radius of approximately 50 meters and a casualty radius of 100 meters. The weapon was finally authorized as an option by the December 1944 TO&E, and by 1945 was employed by all airborne divisions in the European Theater. The infantry used 1 ton cargo trucks as the prime mover. 81mm mortar = 75m, 50m, <30m 105mm ground burst = 100m, 75m, <30m 155mm ground burst = 150m, 100m, <50m for airburst, the rule of thumb is to assume Zone And Sweep directed the battery to fire a Battery One pattern on the target and also one kill radius beyond, below, left and right of the target, expending 30 rounds, patterning an "X" on the target and surrounding area. In an emergency, gunners were authorized to fire M1 HE rounds prepared for the Howitzer M2, but only with charges from 1 to 3. M1 HE rounds for the M3 could be fired from an M2 with any charge. The weapon, initially designated T7, featured a barrel from the 105mm Howitzer M2, shortened by 27 inches (690mm) and combined with the recoil system and carriage from the 75 mm pack howitzer. [13], HEAT M67 Shell had non-adjustable propelling charge. A source gives 13 metres [1] for 100% lethality. Lethal radius is a variable- it depends what you mean! 105mm Howitzer Motor Carriage T38 - based on the, 105mm Howitzer Motor Carriage T82 (M3 in mount M3A1) - based on the, This page was last edited on 25 September 2022, at 23:31. [1] In an assessment written after the war "The cannon company of 1943-45 failed to live up to the expectations of the force designers of 1942. An artillery crewman from Alpha . 1/4 ton jeeps were used as prime movers. [6] They were used early in the Korean War as ROK divisional artillery. It was the standard U.S. light field howitzer in World War II and saw action in both the European and Pacific theaters and during the Korean War. A howitzer crew with 2nd Battalion, 12th Field Artillery Regiment, Alpha Battery, 2nd Platoon fires artillery in Afghanistan in support of Operation Freedom Sentinel, July 23 2018. . Neither reached mass production. Also, I noticed the references to "danger close". This howitzer, the M3, had a shorter barrel than the regular 105-mm howitzer M2, possessed no ballistic shield, and had an effective range of only 7,250 yards (6.63km) as compared to 12,500 yards (11.4km) for the M2."[5]. The main problem was the substitution of towed low-velocity howitzers for the self-propelled versions as originally intended. M101 howitzer. there are three sets of rules for infantry conduct: close barrage training (zero casualties), "battle innoculation" training (1% casualties) and close barrage in action (stay as close as you can). The gun utilized the barrel of the 105 mm Howitzer M2, shortened and fitted to a slightly modified split trail carriage of the 75 mm pack howitzer.. Shrapnel rounds give a lethal radius of 23 m. [2] The Safe Distance is 550 m. Long Answer The problem could be solved by use of faster-burning powder, and otherwise, the design was considered acceptable and was standardized as the 105mm Howitzer M3 on Carriage M3. The M3 was the primary weapon of these companies, and appeared in the table of organization and equipment (T/O&E) from early 1944 (six, in three platoons of two)[4] Often the cannon companies were integrated into the division artillery. The gun fired semi-fixed ammunition, similar to the ammunition of the M2; it used the same projectiles and the same 105mm Cartridge Case M14, but with different propelling charge. For blank ammunition, a shorter Cartridge Case M15 with black powder charge was used.[13]. [1], The howitzer was designed to fire the same ammunition as the M2 howitzer, however, it was found that the shorter barrel resulted in incomplete burning of the propelling charge. The process of building airborne forces in 1941 led to a requirement for an air-portable 105mm howitzer. The howitzer was used by the U.S. Army during World War II. The latter used faster burning powder to avoid incomplete burning; it consisted of a base charge and four increments, forming five charges from 1 (the smallest) to 5 (the largest). The carriage was soon succeeded by the M3A1, which had trails made from thicker steel plate. T10 - variant with elevation increased to 65 degrees. It was issued to airborne units and the cannon companies of infantry regiments. A M3 howitzer outside the Army Museum in Honolulu, Hawaii. title: v7 created date: kill radius compared likely kill radius 15 meters likely injury radius 150 meters likely kill radius 33.5 meters likely injury radius 350 meters hellfire jdam 2000lb (not inert): 155 mm artillery shell likely injury radius 20 meters likely kill radius 50150 meters. The 105 mm Howitzer M3 was a U.S. light howitzer designed for use by airborne troops. It should be noted that the "radius" represents the distance where 50% of the people within the radius would be killed or injured. M3 - based on M3A1 carriage for the 75mm field howitzer. [1], Production started in February 1943 and continued until May 1944; an additional batch was produced from April to June 1945. Therefore, direct comparison is often impossible. Lethal to the enemy or too dangerous for you! Later increased to four battalions, one, between 1943 and 1945, was converted to 105mm M3. There were two proposals for a self-propelled artillery piece armed with the M3. The M101A1 (previously designated M2A1) howitzer is an artillery piece developed and used by the United States.

Entering production in 1941, it quickly gained a reputation for accuracy . The 105mm Howitzer M3 was a U.S. light howitzer designed for use by airborne troops. [1][3], The initial production of the M3 was adequate to equip the cannon companies of the three hundred infantry regiments that had been forecast in the initial war plans. Typical kill radius was 30 meters for a 105mm or 4.2inch round, 50 meters for a 155mm and 80 meters for an 8inch round. Different methods of measurement were used in different countries / periods. [1], Even though the M3 was not mentioned in the February 1944 T/O&E, shortly before the Normandy airdrops some airborne divisions received a 105mm glider field artillery battalion equipped with them as a supplement to their existing three 75 mm howitzer battalions (designated the M1A1 during World War II). A prototype reached trials at Aberdeen Proving Ground in March 1942. A small number of M3s were supplied via lend lease channels to France (94), United Kingdom (2) and countries of Latin America (18). Short Answer The lethality from a 105 mm comes from splinters, not blast. but an artillery round that detonates closely enough to your concrete or steel will kill you a different way: the blast wave. Even stronger tubular trails were designed, but never reached production. The howitzer was used by the U.S. Army during World War II.It was issued to airborne units and the cannon companies of infantry regiments The gun utilized the barrel of the 105 mm Howitzer M2, shortened and fitted to a slightly modified split trail carriage of the 75 mm pack howitzer.
