NationMaster - Encyclopedia: 37mm Gun M3

The 37mm Gun M3 was the first dedicated anti-tank gun fielded by the US forces. Introduced in 1940, it became the standard anti-tank gun of the US infantry in World War II, until replaced in this role by more powerful 57mm Gun M1 in 1943-44, long after the evolution of German tanks rendered the 37 mm piece obsolete. In the Pacific, where the armor threat was less significant, the M3 remained in service until the end of the war. Like many other light anti-tank guns, the M3 was widely used as an infantry support weapon, firing high-explosive and canister rounds. Image File history File links 37-mm-at-gun-fort-benning-1. ...

Development history

In mid-1930s the US Army had yet to field a dedicated anti-tank gun. Anti-tank companies of infantry regiments were armed with .50-cal machine guns. Although there were some considerations of replacing the MGs with more powerful weapon, only after the outbreak of the Spanish Civil War the situation started to change. Although the war was characterized by a growth of the tank threat, the experience of the fighting in Spain suggested that light anti-tank gun, such as the German PaK 35/36, gives an adequate solution.^[1] Image File history File links 37mm_gun_crew_in_battle_lg. ...

In January 1937, inspired by reports about successful use of anti-tank guns in Spain, the Ordnance Committee recommended development of a such a weapon;^[1] two PaK 36 guns were acquired for study.^[2] The Infantry branch was chosen to oversee the work as a future primary user of the weapon. While some Ordnance officers considered larger caliber, the Infantry insisted on 37 mm since it wanted lightweight gun which could be moved around by a four man crew. In August 1938 the War Department notified the Ordnance that there will be no funding anytime soon for a larger gun.^[1] 1937 (MCMXXXVII) was a common year starting on Friday (link will take you to calendar). ...

Development and testing continued until late 1938. Several variants of gun and carriage were proposed until on 15 December a combination of T10 gun and T5 cariage was officially adopted as 37mm Gun M3 and Carriage M4.^[1] Although patterned after PaK 36 and often referred to as a copy of it^[3], the M3 differed from the German design in many aspects. 1938 (MCMXXXVIII) was a common year starting on Saturday (link will take you to calendar). ...

The gun was manufactured by Watervliet Arsenal and the carriage by Rock Island Arsenal. First pieces were deliviered early in 1940.^[1] The production continued until 1943.

Some minor changes in the gun construction were introduced during the production period. The carriage received improved traverse controls (carriage M4A1, standardized on 29 January 1942); although Ordnance requested upgrade of all M4 carriages to M4A1, the process wasn't completed.^[1] Other change was threaded barrel end to accept a big five-port muzzle brake (gun M3A1, adopted on 5 March 1942). According to Zaloga,^[1] the latter was intended to avoid kicking too much dust under dry ground conditions; it turned out to be a safety problem when used with canister ammunition and consequently never saw combat. Other sources mention the muzzle break as intended to soften a recoil and say that it was dropped simply because additional recoil control measures weren't really needed.^[2]^[5] January 29 is the 29th day of the year in the Gregorian calendar. ... 1942 (MCMXLII) was a common year starting on Thursday (the link is to a full 1942 calendar). ...

In attempt to increase the armor penetration of the M3 several squeeze bore adaptors (including the British Littlejohn adaptor) were tested; none were adopted. Experiments with rocket launchers on the M4 carriage (e.g. 4.5in rocket projector T3) also didn't produce anything practical.^[1] The Littlejohn adaptor was a device that could be added to the British QF 2 pounder (40 mm) anti-tank gun. ...

Two tank gun variants were developed based on the barrel of the M3. The first, initially designated M3A1 but renamed M5 on 13 October 1939, was shortened by 5.1 inches (3.5 calibers) to avoid damage to the tube in wooden areas. Later a variant with semi-automatic breech (with empty cartrige ejection) was developed. This variant - M5E1, adopted as M6 on 14 November 1940) - also recieved a full length barrell.^[6] These guns were mounted on several models of tanks and other armored vehicles, most of them American, though an exception existed in the form of the British Humber Armoured Car. In addition, M3 in its original variant was mated to a number of other vehicles resulting in an assortment of 37mm gun motor carriages.

Organization and employment

Under the Table of Organization and Equipment (TO&E) active in 1941, each infantry battalion had an anti-tank platoon with three 37mm guns and each regiment an anti-tank company with nine, totaling 18 pieces per regiment. The TO&E named 3/4 ton trucks as prime movers, but many units received the 1/4 ton truck (better known as the jeep) instead. Two anti-tank companies were also supposed to be a part of the divisional anti-tank battalion (along with eight 75 mm guns), but in December 1941 these battalions were reorganized as independent tank destroyer battalions and eventually opted for self-propelled anti-tank guns.^[7] An airborne division had 36 37 mm anti-tank guns under TO&E of October 1942: four in divisional artillery, eight in glider infantry regiment, 24 in AA/AT battalion.^[8] This article is about the year. ...

The M3 saw action for the first time during the defense of the Philippines in December 1941.^[7] Throughout the war it remained effective against Japanese vehicles (which were thinly armored and, moreover, were rarely committed in large groups) and its weight allowed to manhandle it with relative ease (e.g. when attacked by Japanese tanks on Betio, marines were able to manually heave the M3 over the five-foot-high seawall^[9]). Because of those factors, the gun remained in service with the Marine Corps until the end of the war, being employed as both anti-tank and infantry support piece (in the latter role the M3 with its small high-explosive projectile was only somewhat effective). Some Army units in the Pacific also used the gun until the end of the hostilities.^[7] Unhappy with an unusually low shield of the M3, some Marine Corps units extended them to provide better protection. A standard kit was tested in 1945 but was never issued.^[10] Combatants the Philippines, United States Japan Commanders Douglas MacArthur/ Jonathan M.

The experience of the North African Campaign was completely different. The gun was soon found out to be not powerful enough to deal with German Panzer III and Panzer IV. After the nearly disastrous Battle of Kasserine Pass in February 1943, reports from the involved units mentioned 37mm projectiles "bouncing off like marbles" from turret and front armor of German medium tanks and proclaimed the gun "useless unless you have gun crews with the guts to stand and shoot from 100 yards". The Army Ground Force, however, was still uncertain whether the gun was inadequate or was simply incorrectly used; so the TO&E from March left the M3 in place. Only on 26 May 1943 another new TO&E had the M3 replaced by the 57mm Gun M1 (the US-produced version of the British QF 6 pounder), with Dodge 1 1/2 ton trucks as prime movers. But only by spring 1944 did the 57mm gun reach battlefield in large numbers.^[7] During World War II, the North African Campaign, also known as the Desert War, took place in the North African desert from September 13, 1940 to May 13, 1943. ...

Meanwhile, the Italian campaign was launched. On the day of the Sicily landing - 10 July 1943 - M3 guns helped to repel an attack by Italian Renault R 35 tanks, but were inefficient in a subsequent encounter with Tigers from the Herman Göring division. The Italian theater had lower priority for reequipment than Northwest Europe, and some M3s were still in use there late in 1944.^[11] The Italian Campaign of World War II was the name of Allied operations in and around Italy, from 1943 to the end of the war. ...

By mid-1944 the M3 fell out of favor even with airborne troops, despite their natural preference for compact and lightweight weapon systems. Although the TO&E of February 1944 still had airborne divisions keep their 37mm guns, before the Normandy airdrops the two divisions involved - the 82nd and the 101st - were reequipped with British-manufactured 6 pounders, of a version designed to fit into the Horsa glider.^[8] Combatants United States United Kingdom Canada Free France Poland Germany Commanders Dwight Eisenhower (Supreme Allied Commander) Bernard Montgomery (land) Bertram Ramsay (sea) Trafford Leigh-Mallory (air) Gerd von Rundstedt (OB WEST) Erwin Rommel (Heeresgruppe B) Friedrich Dollmann () Strength 326,000 (by June 11) Unknown, probably some 1,000,000 in...

The only major lend lease recipient of the M3 was the Chinese Kuomintang Army (1,669 pieces). The gun was also supplied to Bolivia (4), Canada (3), Chile (198), Colombia (4), Cuba (1), El Salvador (9), France (130), Great Britain (78), USSR (63) and other countries (100).^[12] Some nations still had the gun in service in early 1970s.^[5] President Roosevelt signs H.R. 1776, the lend-lease bill to give aid to Britain and China Lend-Lease was the major United States program 1941-1945 which enabled the United States to give the United Kingdom, the Soviet Union, China and other Allied nations with vast amounts of war...
