Soviet 121.92 mm (4.8 inch) howitzer^[source]

The 122 mm howitzer M1938 (M-30) ( GRAU index: 52-G-463 ) is a Soviet 121.92 mm (4.8 inch) howitzer . The weapon was developed by the design bureau of Motovilikha Plants , headed by F. F. Petrov , in the late 1930s, and was in production from 1939 to 1955. The M-30 saw action in World War II , mainly as a divisional artillery piece of the Red Army (RKKA). Captured guns were also employed later in the conflict by the German Wehrmacht and the Finnish Army . Post World War II, the M-30 saw combat in numerous conflicts of the mid- to late twentieth century in service of other countries' armies, notably in the Middle East .^[source]122 mm howitzer M1938 (M-30) · Lead; only the objects and conditions stated in this passage

In 1930 Red Army (RKKA) authorities started to look for a new divisional-level howitzer to replace the pre-World War I 122 mm howitzer M1909 and 122 mm howitzer M1910 . Although both pieces were eventually modernized, resulting in the 122-mm howitzer M1909/37 and the 122-mm howitzer M1910/30 respectively, these upgrades did not address some shortcomings in the original designs.^[source]122 mm howitzer M1938 (M-30) · Development; only the objects and conditions stated in this passage

The first attempt to develop a new howitzer was made by the KB-2 design bureau under the supervision of German engineers. The design, known as Lubok , reached trials in 1932 and in 1934 was adopted as the 122-mm howitzer model 1934 . It had a 23 caliber barrel, a maximum elevation of 50°, traverse of 7°, and a combat and travelling weight of 2,250 and 2,800 kg respectively. Like its predecessors, Lubok had a fixed trail carriage and although it was equipped with suspension, its wheels lacked tires , limiting towing speed to only 10 km/h. Nevertheless, it was undoubtfully superior to the M1910/30 which remained in production until 1941. However, after eight pieces were built in 1934–1935, production was stopped for unclear reasons, possibly relating to the disbanding of KB-2.^[source]122 mm howitzer M1938 (M-30) · Development; only the objects and conditions stated in this passage

In the mid-1930s, the Main Artillery Directorate (GAU) considered a switch to 105 mm guns as used by some other armies. A smaller shell meant that the gun could be lighter and consequently more mobile. On the other hand, a 105 mm gun would also be less powerful. Moreover, there was no Russian or Soviet experience with 105 mm ammunition, while for the 122 mm the country already possessed both production lines and large numbers of already manufactured shells (however similar 107 mm manufacturing equipment and ammunition—for the 107-mm gun M1910 —was available). Finally in 1937 the RKKA Head of General Staff I. I. Egorov supported retaining 122 mm ammunition.^[source]122 mm howitzer M1938 (M-30) · Development; only the objects and conditions stated in this passage

The U-2 (barrel length 21 calibers , chamber volume 3.0 litres , horizontal sliding breechblock from Lubok, muzzle brake , combat weight 2,030 kg) reached trials on 5 February 1939 and was rejected because of insufficient carriage strength and inferior ballistics. The F-25 project (barrel length 23 calibers, chamber volume 3.7 litres , horizontal sliding breechblock from Lubok, muzzle brake , combat weight 1,830 kg) was closed by GAU on 23 March 1939 as GAU considered it redundant to the M-30 which had reached trials earlier. The latter, after being returned several times for revision, was finally adopted in September 1939 as the 122 mm divisional howitzer M1938 ( Russian : 122-мм гаубица образца 1938 года (М-30) ). Its GAU index number was 52-G-463 .^[source]122 mm howitzer M1938 (M-30) · Development; only the objects and conditions stated in this passage

A. B. Shirokorad, a well-known author of books detailing the history of the Soviet artillery, has claimed that the F-25 could have been developed into a better gun than the M-30. Grabin's design was about 400 kg lighter, had a greater traverse and had better ground clearance – all this was achieved, according to Shirokorad, without sacrificing ballistics (same barrel length, chamber volume and muzzle length). Considering how long it took to finish the development of the M-30, the F-25's schedule possibly did not significantly lag behind.^[source]122 mm howitzer M1938 (M-30) · Development / M-30 versus F-25; only the objects and conditions stated in this passage

The stronger carriage of the M-30 could be used – and in fact was used – for more powerful artillery pieces (see 152-mm howitzer M1943 (D-1) ).^[source]122 mm howitzer M1938 (M-30) · Development / M-30 versus F-25; only the objects and conditions stated in this passage

Mass production of M-30 howitzers began in 1940 at Plant No. 92 in Gorky and No. 9 in Sverdlovsk . The former took part in the production of M-30s only in 1940, building a total of 500 pieces. In addition to towed howitzers, Plant No. 9 produced M-30S barrels for arming SU-122 assault guns. Some 700 barrels (including both serial-production and experimental articles) were manufactured for this purpose. Mass production continued into 1955. In 1950–1960, the M-30 was also produced by Huta Stalowa Wola in Poland where it was known as Wz.1938 .^[source]122 mm howitzer M1938 (M-30) · Production; only the objects and conditions stated in this passage

The M-30 had a modern split trail carriage with leaf spring suspension and steel wheels with rubber tires. It was usually towed by vehicle without a limber . The carriage allowed for a towing speed of up to 50 km/h on paved road and up to 35 km/h on gravel or dirt roads, although the gun could also be moved by a team of six horses, in which case a limber was used. When the trails were swung open the suspension locked automatically . In an emergency it was possible to shoot in a "single trail" mode, at the price of a drastically reduced traverse (1°30'). The time required to set the gun up for combat was about 1–1.5 minutes.^[source]122 mm howitzer M1938 (M-30) · Description; only the objects and conditions stated in this passage

The M-30 was a divisional level howitzer. According to the 1939 organization, each rifle division had two artillery regiments ; one light regiment (a battalion of 76 mm guns; two mixed battalions with one battery of 76 mm guns and two batteries of 122 mm howitzers) and one howitzer regiment (a battalion of 122 mm howitzers and a battalion of 152 mm howitzers), giving 28 122 mm howitzers per division. In June 1940, one more battalion of 122 mm howitzers was added to the howitzer regiment, bringing the number of guns in each unit to 32. In June 1941, the howitzer regiment was removed and the number of howitzers dropped to 16. This organization was used throughout the war except in Guards rifle divisions, which from December 1942 had three artillery battalions (two batteries of 76 mm guns and one battery of 122 mm howitzers each), totaling 12 howitzers. From December 1944, they received an extra howitzer regiment (5 batteries, 20 howitzers) and from June 1945 rifle divisions were reorganized identically.^[source]122 mm howitzer M1938 (M-30) · Organization and employment / Red Army; only the objects and conditions stated in this passage

Mountain rifle divisions in 1939–1940 had one battalion of 122 mm howitzers (3 batteries, 9 guns). From 1941,they received instead one artillery regiment (2 battalions, each of four-gun batteries) with 24 howitzers; however, in early 1942, only one battalion (2 batteries, 8 howitzers) remained. From 1944, howitzers were removed from mountain rifle divisions.^[source]122 mm howitzer M1938 (M-30) · Organization and employment / Red Army; only the objects and conditions stated in this passage

Motorized divisions had two mixed battalions (a battery of 76 mm guns and two batteries of 122 mm howitzers), totaling 12 howitzers. Tank divisions had one battalion with 12 howitzers.

Until late 1941, rifle brigades had a battery of four 122 mm howitzers. 122 mm howitzers were also used by the howitzer brigades of the Reserve of the Main Command (72–84 pieces).^[source]122 mm howitzer M1938 (M-30) · Organization and employment / Red Army; only the objects and conditions stated in this passage

By 1 June 1941, 1,667 M-30s were in service, comprising only a fraction of the RKKA divisional howitzers.

M-30 howitzers were primarily employed for indirect fire against enemy personnel. They were also used against field fortifications , for clearing minefields and for breaching barbed wire . Their HE-fragmentation shells presented a danger to armoured vehicles. Fragments created by the explosion could penetrate up to 20 mm of armour, – enough against thinly armoured vehicles. The shells could also damage chassis, sights or other elements of heavier armoured vehicles.^[source]122 mm howitzer M1938 (M-30) · Organization and employment / Red Army; only the objects and conditions stated in this passage

The gun was eventually replaced by the 122-mm howitzer D-30 after the latter was adopted for service in 1960. A small number of operational M-30 howitzers are still present in Russian Army ordnance depots. They are being gradually withdrawn from reserve. M-30s featured in many Soviet movies used for novice artillery crew training. These movies were made in the 1960s when more modern D-30 howitzers were becoming available; however, the M-30 was considered by authorities as much more suitable for training purposes. The movies are still in use despite the absence of M-30 howitzers even in practice exercises.^[source]122 mm howitzer M1938 (M-30) · Organization and employment / Red Army; only the objects and conditions stated in this passage

A number of M-30s fell into the hands of the Wehrmacht in 1941–1942 and were adopted as 12,2 cm s.F.H.396(r) heavy howitzers. Germany began mass production of 122 mm ammunition for these and other captured howitzers, producing 424,000 shells in 1943, 696,700 in 1944 and 133,000 in 1945.

It is hard to compare the M-30 directly with contemporary foreign guns since the artillery of France, Germany and United States employed in similar roles was either the much smaller 105 mm (Great Britain used the even smaller—87.6 mm— 25 pounder gun-howitzer ) or much larger 150 to 155 mm caliber guns. Howitzers of similar calibers existed but most of those were World War I era pieces, such as the Vickers 114 mm howitzer used by the Finnish Army. Naturally, 150 mm howitzers were more powerful, but much heavier than the M-30; while 105 mm pieces were lighter but their smaller shells contained less explosive.^[source]122 mm howitzer M1938 (M-30) · Summary; only the objects and conditions stated in this passage

The most direct German equivalent was the 10.5 cm leFH 18 light howitzer. Weighing 1985 kg, it had a maximum elevation of 42°, muzzle velocity of 470 m/s and maximum range of 10,675 m. In the upgraded leFH 18/40 version, muzzle velocity was improved to 540 m/s, elevation to 45° and range to 12,325 m. About equal in range, the German howitzer had a less powerful HE shell and its smaller maximum elevation made it less effective against dug-in troops, although it also weighed some 400 kg less than the M-30. Both guns were well suited for mass production with 16,887 M-30s and 15,388 leFH 18 built in 1941–45.^[source]122 mm howitzer M1938 (M-30) · Summary; only the objects and conditions stated in this passage

The M-30 could fire all types of 122 mm howitzer ammunition used by the RKKA, including old Russian and imported shells. During and after World War II, new types of ammunition were developed, notably HEAT shells. The World War II era HEAT shell BP-460A could pierce 100–160 mm of armor at 90°; the post-war BP-1 managed 200 mm at 90°, 160 mm at 60°, and 80 mm at 30°. HE-Frag projectiles of type OF-462 that were initially developed for the M-30 howitzer can be fired from modern 122 mm ordnance pieces and are still in Russian Army service.^[source]122 mm howitzer M1938 (M-30) · Ammunition data; only the objects and conditions stated in this passage
