The122 mm howitzer M1938 (M-30) (GRAU index:52-G-463) is aSoviet 121.92 mm (4.8 inch)howitzer. The weapon was developed by the design bureau ofMotovilikha Plants, headed byF. F. Petrov, in the late 1930s, and was in production from 1939 to 1955. The M-30 saw action inWorld War II, mainly as a divisional artillery piece of theRed Army (RKKA). Captured guns were also employed later in the conflict by the GermanWehrmacht and theFinnish 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 theMiddle East.
In 1930Red Army (RKKA) authorities started to look for a new divisional-level howitzer to replace the pre-World War I122 mm howitzer M1909 and122 mm howitzer M1910. Although both pieces were eventually modernized, resulting in the122-mm howitzer M1909/37 and the122-mm howitzer M1910/30 respectively, these upgrades did not address some shortcomings in the original designs.[citation needed]
The first attempt to develop a new howitzer was made by theKB-2 design bureau under the supervision of German engineers. The design, known asLubok, reached trials in 1932 and in 1934 was adopted as the122-mm howitzer model 1934. It had a 23caliber 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 lackedtires, 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.[8]
In the mid-1930s, theMain 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 the107-mm gun M1910—was available). Finally in 1937 the RKKA Head of General Staff I. I. Egorov supported retaining 122 mm ammunition.[9]
Consequently, three howitzers were trialled in 1938–1939. The design bureau ofUZTM (Ural Heavy Machinery Plant, Russian: Уральский Завод Тяжёлого Машиностроения, УЗТМ), which was ordered by GAU to design the new howitzer, developed a piece designatedU-2. Similar projects were privately undertaken by the design bureaus ofMotovilikha Plants, headed byF. F. Petrov (M-30), and by theNo. 92 plant underV. G. Grabin (F-25).
The U-2 (barrel length 21calibers, chamber volume 3.0litres, 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 3.7litres, 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 the122 mm divisional howitzer M1938 (Russian:122-мм гаубица образца 1938 года (М-30)).[8] Its GAU index number was52-G-463.[10]
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.[when?][8] 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.
There is no official document explaining the advantages the M-30 had over the F-25. Factors that could have influenced the GAU decision were:
Mass production of M-30 howitzers began in 1940 atPlant No. 92 inGorky andNo. 9 inSverdlovsk. 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 armingSU-122 assault guns. Some 700 barrels (including both serial-production and experimental articles) were manufactured for this purpose. Mass production continued into 1955.[citation needed] In 1950–1960, the M-30 was also produced by Huta Stalowa Wola in Poland where it was known asWz.1938.[11]

The barrel of the M-30 was of built-up construction and consisted of a liner, jacket and breech. Thebreechblock was ofinterrupted screw type, with forcedcartridge case extraction. The gun was equipped with a hydraulicrecoil buffer and hydropneumatic recuperator. A panoramicsight was used for both indirect and direct fire.[citation needed]
The M-30 had a modernsplit trail carriage withleaf spring suspension and steel wheels with rubber tires. It was usually towed by vehicle without alimber. 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.[citation needed]
The carriage of the M-30 was later used for theD-1 152 mm howitzer.

The M-30 was a divisional level howitzer. According to the organization of 1939, each rifledivision had two artilleryregiments; one light regiment (abattalion of 76 mm guns; two mixed battalions with onebattery 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 inRussian 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.[citation needed]
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 from 3 four-gun batteries) with 24 howitzers, but in early 1942 only one battalion (2 batteries, 8 howitzers) remained. From 1944 howitzers were removed from mountain rifle divisions.
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. Cavalry divisions until August 1941 had two batteries of 122 mm howitzers, totaling eight, before the divisional artillery was removed.
Until late 1941 riflebrigades 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).[8]
By 1 June 1941 1,667 M-30s were in service, comprising only a fraction of the RKKA divisional howitzers. As the war progressed, their share grew rapidly due to mass production and because many older guns were lost in combat in 1941–42.
M-30 howitzers were primarily employed forindirect fire against enemy personnel. They were also used against fieldfortifications, for clearingminefields and for breachingbarbed 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.[citation needed]
For self-defense against enemy tanks aHEAT shell was developed in 1943. Before 1943, crews were required to rely on the high-explosive action of their regular ammunition, with some degree of success. According to a German report from 1943, even aTiger was once heavily damaged bySU-122 assault guns firing high-explosive shells.[12]
M-30 howitzers were towed by a variety of means, from horses, oxen[13] and both Soviet and American-producedLend-Lease trucks (such as theDodge WC series andStudebaker US6s) andSTZ-5 andYa-12 purpose-built artillery tractors. When necessary, the gun could be manhandled by its artillery crew.
In 1944, the Artillery Regiment of a typical Russian Rifle Division was armed with 36 122mm Howitzers, along with 72 76.2mm ZiS-3 field guns.[14]
The gun was eventually replaced by the122-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.
In August 2024, Russian personnel released video footage of combat use of the M-30 by theRussian Armed Forces during theRussian invasion of Ukraine.[15][16]
A number of M-30s fell into the hands of theWehrmacht in 1941–1942 and were adopted as12,2 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. Some captured M-30s were used in theAtlantic Wall fortifications.[17]
TheFinnish Army captured 41 guns of the type and adopted them as the122 H 38. These guns fired 13,298 shells in combat; only a few pieces were lost. The gun was well liked; some were used for training or stored in depots until the mid-1980s.[18]
TheKingdom of Romania captured in 1941 a number of 477 various types of 122 mm howitzers and guns including M1931/37 and were used as divisional artillery for units rebuilt in 1943. The M-30 was used on the first four prototypes of theMareșal tank destroyer, having a muzzle brake attached to it by the Romanians.
After World War II the gun was supplied to many countries around the globe. With the Egyptian andSyrian armies it saw action in theArab-Israeli Wars. Some of these guns were captured by Israel, although it is unclear whether they were ever employed by theIsraeli Defense Forces. ThePeople's Republic of China organized their own production of M-30 howitzers under theType 54 designation.[19]
According toIan V. Hogg, the M1938 howitzer "must, surely, be the most prolific piece of artillery in history".[20]

The M-30 was mounted on the following armoured fighting vehicles (AFV):
In the M-30, RKKA units finally received a modern divisional howitzer which successfully combined increased firepower and better mobility with reliability and ease of use. A summary of its employment by the Red Army was provided by MarshalG. F. Odintsov [ru], who said "Nothing can be better".[9] The long post-war employment of the howitzer is additional testimony to its combat and operational utility and effectiveness.
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 theVickers 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.
The most direct German equivalent was the10.5 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 M-30. Both guns were well suited for mass production with 16,887 M-30s and 15,388 leFH 18 built in 1941–45.[citation needed]
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.[citation needed]
