The 2S3 "Akatsiya" (Russian - 2С3 «Акация», English - 2S3 "Acacia") is a 152 mm self-propelled howitzer developed by the Soviet Union as a response to appearance of American 155 mm M109 howitzer and produced during the Cold War. A project development started in 1967 according to the Resolution of the Council of Ministers of USSR from 4 July, 1967. 2S3 is its GRAU index for self-propelled artillery systems. The artillery system was developed in Sverdlovsk (design bureau No. 9 of Engineering Works named for M. I. Kalinin) and the chassis was developed by "Uraltransmash" Ural Vehicle Engineering Works (UZTM).

Description

Designated "M1973" by the US Army, the "Akatsiya" is armed with a 152 mm howitzer based on the Soviet D-20 howitzer and is sometimes confused with the M109 self-propelled howitzer. The official Soviet designation was SO-152, but it is more known as the 2S3 "Akatsiya". The factory designation of the gun is D-22 and is also known as the 2A33 (GRAU designation).

Driver's and engine-transmission compartments are located in a front part of a hull, fighting compartment with rotatory turret - in middle and rear parts of the hull. The armour is welded rolled steel. Howitzer is equipped with R-123 radio set, R-124 intercom, automatic NBC system with filtration unit and fire-fighting equipment. The V-59 12-cylinder four stroke water-cooled diesel engine connects with a mechanical twin gear transmission, a gear box is in one block with a planetary steering gear. 2S3 has self-entrenching equipment which allows to prepare a trench within 20-40 min.

The crew consists of 4-6 men: a driver, a gunner, a loader, a commander, and two ammunition bearers, which are positioned to the rear of the vehicle feeding rounds through two hatches in the hull rear when in masked firing position.

Armament

The 152.4 mm L/27 howitzer D-22 (2A33) can be elevated from -4° to +60° with a turret traverse of a full 360°. Rate of fire is 2.6 - 3.5 rounds/min depending on fire conditions. Howitzer is equipped with a double-baffle muzzle brake, a semi-automatic vertical wedge breechblock and an ejector. 2S3 has periscopic sight and telescopic sight of direct pointing. Howitzer has separate type of loading with ammunition (40 rounds) arranged in two mechanized stowages (in the turret and in the rear of the hull). The 2S3 "Akatsiya" can fire OF-540 and OF-25 HE-Frag 43.56-kg projectiles (also all types of rounds developed for 152 mm towed howitzer-guns ML-20 and D-20, and for towed howitzer D-1) at a maximum range of 18.5 km depending of used charge or rocket-assisted projectiles to a maximum of 24 km. Other projectiles available to the "Akatsiya" include BP-540 HEAT-FS (sight distance is 3 km, 250 mm armor penetration), Br-540B and Br-540 AP-T (115-120 mm armor penetration at a 1000 m), OF-38 "Krasnopol" laser-guided rocket-assisted projectiles, S1 illuminating, ZH3 smoke, nuclear projectiles (with explosive capacity of 2 kt). Secondary armament represents remotely-controlled 7.62 mm PKT tank machine gun on commander's cupola for anti-aircraft defence and self-defence in close combat.

Maneuverability

The "Akatsiya" chassis is based on that of the Ob'yekt 123 tracked chassis [http://www.jedsite.info/misc/oscar/obyekt_series/obyekt-series.html Ob'yekt series of experimental armoured vehicles] , Mike Grif] of the 2K11 "Krug" surface-to-air missile system; it includes six (rather than seven as in the 2K11 "Krug") twin rubber-tired road wheels, four rubber-tired return rollers (two single and two twin), front drive sprocket with detachable sprocket rings (lantern-wheel gear) and idler wheel per side. The track is 14.375 m long, 482 mm wide and has 115 links. 2S3 "Akatsiya" can cross 0.7 m high vertical obstacles, 3.0 m wide trenches, 1.05 m fording depth and climb 30° gradients. [http://armoured.vif2.ru/2s3.htm Самоходная артиллерийская установка 2С3 "Акация" ] ] [http://legion.wplus.net/guide/army/ar/2s3.shtml 152-мм самоходная гаубица 2С3 "Акация" (2S3 Akatsiya 152-mm self-propelled artillery system) ] ] It can be transported by transport plane An-22 (carries two self-propelled howitzers of this type).

eries production

Two prototypes of 2S3 were built in the end of 1968. Factory tests were finished in October 1969 and they discovered strong gas contamination of fighting compartment during intensive gunnery, especially with the use of small charges. So army inspectors did not accept four 2S3 built in summer 1969 for ground tests. But the problem of gas contamination was solved finally and 2S3 entered service of the Soviet Army in 1971. The first three serial 2S3 were built by UZTM in the end of 1970, in 1971 - nine were produced and the works received the order for 70 2S3 in 1973. The massproduction was finished in 1993.

ervice and combat history

Former USSR

2S3 "Akatsiya" was intended for inventory of artillery regiments of Soviet tank and motor rifle divisions. At first only one gun battalion of each artillery regiment was equipped with 2S3 "Akatsiya" (18 self-propelled howitzers).

In the end of 1980s self-propelled artillery regiments of Soviet first echelon tank and motor rifle divisions (for example, belonged to Group of Soviet Forces in Germany) each had 36 or 54 self-propelled howitzers of this type (2 or 3 gun battalions).

As of now 2S3 "Akatsiya" are used by the following units of the Russian Navy or are stationed in following bases (incomplete list): 385th storage in Lugovoe (near Kaliningrad) which belonged to the Baltic Fleet (24 2S3), storage in Gusev which belonged to the Baltic Fleet (31 2S3), 55th marine division from Vladivostok which belonged to the Pacific Fleet.

8th motor rifle brigade from Tiraspol (Russian operative group in Transnistria) has 36 2S3. All equipment [ [http://www.mil.ru/848/1045/1272/1365/1366/skvo/19274/index.shtml?id=26199 Новости СКВО, News of The Russian Federation Ministry of Defence ] ] of 817th self-propelled artillery regiment of 62nd Russian military base of the North Caucasus Military District was withdrawn from Akhalkalaki, Georgia in 2006 according to the Russian-Georgian Sochi agreement, the regiment has 30 2S3 and it is planned to relocate some of its SPGs to 102nd Russian military base in Gyumri, Armenia.

At the moment 2S3 "Akatsiya" SPG is considered as outdated because of insufficient range of fire in comparison with modern SPGs. Modernized variant 2S3M2 armed with a new 155 mm M-385 howitzer was developed in 2000 and 2 gun battalions of the Russian Army (including one of the 2nd Taman motor rifle division) have been reequipped with 2S3M2 in 2006.
