Development The 125 mm Blank 4X33 round used with Russian Federation and Associated States (CIS) 125 mm tank guns consists mainly of a Zh53 propelling charge, allied to a further charge simulating the auxiliary propellant used with APFSDS rounds. These rounds are fired for battle training or saluting purposes. Description The main charge for the 125 mm Blank 4X33 is a 4Zh52 semi-combustible propellant charge case. This is loaded as normal together with a projectile simulator formed by a cylindrical board and paper case containing a further amount of explosive. Priming is electrical. After firing a stub cartridge case base remains to be automatically or manually ejected from the chamber. The case, made of BW-11 steel, weighs 3.4 kg. It is 140 mm long and has a flange diameter of 171.9 mm. The complete 125 mm Blank 4X33 round weighs 13.4 kg.

125 mm HEAT-FS ammunition
Armament 2A45 and 2A45M tank guns fitted to T-64 and early T-72 MBTs; 2A46 (D-81) and 2A46M (D-81M) tank guns fitted to T-64A and T-72 MBTs; 2A46M1 tank gun fitted to T-80 and T-90E MBTs; 2A75 gun carried by 2S25 self-propelled anti-tank gun; 2A45M Sprut-B towed anti-tank gun. Development There are currently six known types of 125 mm HEAT-FS ammunition although the earliest, the 3BK12M, is now unlikely to be encountered. A checklist of the rounds and projectiles involved is provided below: Round Projectile 3VBK7 3BK12M 3VBK10 3BK14M 3VBK16 3BK18M 3VBK17 3BK21B 3VBK25 3BK29M n/avail 3BK37 The HEAT-FS 3BK14M is an improved version of the earlier 3BK12M and replaced it in service. Unlike earlier similar HEAT-FS projectiles of Russian Federation and Associated States (CIS) origin the 3BK14M uses a standoff spike nose to carry the piezoelectric contact sensor for the base fuze. The 3BK18M is a heavier enhancement of the 3BK14M and uses a copper liner for the shaped charge. By contrast the 3BK21M has a Depleted Uranium (DU) liner which improves penetration performance. The 3BK29 reverts to a copper liner for the shaped charge which is optimised for the penetration of active armours. The 3BK37 projectile was first seen during 1993 and is unusual in having three HEAT charges; one in the nose as a preliminary charge, one in the centre to act as a fuze preliminary charge, and the main charge in the base together with a wave shaper charge, each activated in succession from the nose backwards. As far as is known the 3BK37 is still at the development stage. It has been proposed that the techniques employed with this projectile could be carried over to 100 and 120 mm projectiles. As a typical example, the T-72 usually carries a combat load of 39 rounds, of which only six are HEAT-FS. This reflects the accepted ballistic limitations of the HEAT-FS projectile to the extent that it has been almost entirely replaced by APFSDS-T projectiles for most anti-armour fire missions. A new munitions plant is to be built at Bolangir in Eastern India which, when fully operational, will be able to produce 150,000 rounds of 125 mm ammunition every year. This will presumably include HEAT-FS projectiles. Description In common with the rest of the 125 mm ammunition range, HEAT-FS is a separate loading munition. The projectile is automatically loaded into the breech followed by a semi-combustible propellant case. Projectile bodies are steel and encircled by a single sintered iron driving band 6.86 mm wide. The front of the projectile carries a standoff spike inside which is a piezoelectric contact sensor connected by an internal wire to a base-mounted fuze. The fuze used on the 3BK14M is the V-15 or VG-15 while later models use the 3B15 (3BK18M) or VU-729 (3BK21P). When the fuze functions it ignites the main explosive filling which varies from model to model, resulting in hard target penetration plus fragmentation effects. The explosive filling (usually A-IX-1 or OCFOL) forms a conical shaped charge set behind a liner. The rear of the projectile body carries an extension on which are carried six forward-folding steel fins. The hinged fins snap out once the projectile has left the gun muzzle. The triple-charge warhead 3BK37 weighs 19 kg and has a direct fire range of 1,010 m; maximum aimed range is 4,000 m. Penetration against 60º armour is given as 350 mm following the destruction of reactive armour. Projectiles are fired using a semi-combustible charge case known as the Zh52 and weighing 10 kg; the charge case for the 3BK14M weighed only 5.885 kg. The cases are nitrocellulose impregnated with TNT. A GUV-7 electrical primer is fitted. After firing, a steel stub case weighing 3.4 kg remains to be automatically ejected, although manual ejection may be employed. The case, made of BW 11 steel, is 140 mm long with the flange diameter being 171.9 mm. Most HEAT-FS projectiles have a muzzle velocity of 905 m/s. The 3BK14M warhead can defeat up to 220 mm of armour at 1,000 m, although at that range the probability of a first time hit on a static target has been calculated as 73 per cent. At 1,500 m the hit probability falls to 36 per cent. The maximum direct fire range is around 4,000 m, although at that range accuracy is negligible. The penetration performance of the 3BK18M is not known for certain (a penetration of 260 mm of armour has been estimated) and neither is that for the 3BK21B or the 3BK29. It is known that the 3BK29 is fired with an increased muzzle velocity of 915 m/s and it has been estimated that the 3BK29 warhead could penetrate 300 mm of armour following the detonation of active armour. It has been claimed that the triple-charge warhead 3BK37 can penetrate 350 mm of Rolled Homogeneous Armour (RHA) at an angle of 60º. It is claimed that all these types of round have a service life of up to three years in a tank gun autoloader. Normal shelf life under controlled conditions is of the order of 10 years. The training round used for the latest types of HEAT-FS projectiles is the HEAT-FS-TP 3VP11 using the 3P11 projectile; ealier models used the 3VP5 with the 3P11 projectile. The HEAT-FS-TP 3P11 projectile does not contain explosive but is an exact ballistic match for operational projectiles such as the 3BK18M out to a range of 4,000 m. Weight of the training round is 29 kg complete, 19 kg of which is the projectile. The normal Zh52 propelling charge is employed and handling and loading procedures are identical to those for operational rounds.

125 mm FRAG-HE(FS) 3OF19 and 3OF26
Armament 2A45 and 2A45M tank guns fitted to T-64 and early T-72 MBTs; 2A46 (D-81) and 2A46M (D-81M) tank guns fitted to T-64A and T-72 MBTs; 2A46M1 tank gun fitted to T-80 and T-90E MBTs; 2A75 gun on 2S25 self-propelled anti-tank gun; 2A45M Sprut-B towed anti-tank gun. Development The general purpose 125 mm FRAG-HE(FS) 3OF19 and 3OF26 projectiles may be regarded as scaled-up equivalents of the 115 mm 3OF-18 and 3OF-27, even though the 125 mm 3OF26 is referred to as a second-generation projectile with a preformed fragment warhead. The two 125 mm projectiles differ in other details such as body wall thicknesses, outline and filling but the differences are not readily detectable externally. The 3OF19 is the projectile for the 3VOF22 round, whereas the 3OF26 is the projectile for the 3VOF36 round. For a typical example, the T-72 usually carries a combat load of 39 rounds, 21 of which are FRAG-HE(FS). It is known that 125 mm tank gun ammunition is produced in India but no information is available. A new munitions plant is to be built at Bolangir in Eastern India which, when fully operational, will be able to produce 150,000 rounds of 125 mm ammunition every year; this will presumably include FRAG-HE(FS) ammunition. A 1991 RFAS reference mentions a 125 mm anti-personnel flechette projectile but no information is yet available. Description In common with the rest of the 125 mm ammunition range, the FRAG-HE(FS) 3OF19 and 3OF26 are separate loading munitions. They are automatically loaded into the breech followed by a semi-combustible propellant case. The 3OF19 and 3OF26 are both steel-bodied projectiles with conventional outlines. The bodies have boat tails and their bases thread into a slender curved steel extension assembly, with four forward-folding steel fins which snap out once the projectile has left the gun muzzle (overall fin span is 356 mm). There are two copper driving bands spaced 77 mm apart. The front band is 13 mm wide, with the rear band 7 mm wide. The explosive fillings vary. The 3OF19 contains 3.1485 kg of TNT while the 3OF26 contains 3.14 kg of A-IX-2 (RDX/Aluminium/Wax) surrounded by preformed steel fragments. The OF-19 projectile uses a nose-mounted point impact fuze known as the V-429E and made of steel, threaded into a steel nose adaptor. The prefragmented multipurpose and anti-helicopter 3OF26 FRAG-HE round fitted with an MTSQ fuze weighs 33 kg complete, with the OF-26 projectile weighing 23.2 kg. On detonation, the projectile creates between 600 and 2,000 fragments. Maximum range that can be selected with the fuze is 5,000 m and maximum possible range is 9,700 m. Muzzle velocity is 850 m/s. The 3OF19 projectiles are fired using a semi-combustible charge case known as the Zh40, weighing 5.885 kg; the 3OF26 uses the Zh52 case weighing 10 kg and containing 5 kg of 15/1 Tr VA and 12/7 VA propellant plus S-1 decoppering agent. The cases are nitrocellulose impregnated with TNT. Priming is electrical using a GUV-7 primer 24 mm long. After firing, a steel stub case weighing 3.4 kg remains to be automatically ejected, although manual ejection may be employed. The case, made of BW 11 steel, is 140 mm long with the flange diameter being 171.9 mm. The muzzle velocity of both projectiles is 850 m/s. Maximum range is 9,400 m for the 3OF19 and 12,200 m for the 3OF26. It is claimed that all these types of round have a service life of up to three years in a tank gun autoloader. Normal shelf life under controlled conditions is of the order of 10 years. A training round intended specially for training tank crews is the 125 mm VOFT22 training round with an OFT-19 HE-T projectile. The projectile is fired at a muzzle velocity of 850 m/s with a No 1 tracer element burning for up to 3 seconds from a location in the base so that the trajectory can be followed for training assessment and marking purposes. As the projectile passes through a soft target, the nose-mounted VUBS-1M super-quick point detonating fuze functions to detonate the projectile's Trotyl bursting charge less than 5 m behind the target. Should the projectile fail to hit a target it will self-destruct after about 4 to 6 seconds at a maximum range of 12,220 m. The complete VOFT22 round weighs 32.5 kg. The 125 mm VOFT22 training round is marketed by Kintex of Bulgaria . A short-range training round known as IDA is produced in both the Czech Republic and Slovakia . Equipped with a tracer, the DZ 75 AU base time fuzed round will self-destruct 4.5 seconds (±0.5 second) after firing, equating to a range of 2,700 to 3,300 m. The IDA contains a bursting charge weighing 3.05 kg. This round requires a safety template 5,000 m long Authorised fuzes OF-19, PD V-429E; OF-26, MTSQ, type not yet known Equivalent rounds BULGARIA Marketed by: Kintex Type: 125 mm HE 3VOF22 Description: Projectile is 3OF19 with filling 3.15 kg TNT.
