T-90ms Tagil: Firepower

UBM "Breakthrough" is unified for the installation of guns 2A46M-5 or with the placement of the conveyor 2A82 gun with automatic loader in the bottom of the housing.

2A46M-5. Smoothbore gun 2A46M-5 is well known modernized tool 2A46M (D-81TM). The design of the upgraded guns ensures interchangeability with the gun 2A46M (2A46M-1) with the substitution of body armor and attachment points tsapfennyh devices with the installation of additional balancing loads on tank factories. Apart from the new shots, gun design ensures the applicability of shots of all types and indexes of 2A46M gun ammunition, including TOUR. Upgraded gun 2A46M-5 has the following structural differences from the production of guns 2A46M:
trunk has differentiated tolerance raznostennostennosti in the muzzle of the
variation in wall thickness less than 0.6 mm,
• hardness of the barrel increased to 420 kgf / cm
• barrels of guns 2A46M-5 interchangeable with barrel guns 2A46M;
• guide the trunk in a cradle prism type
• reduced Cantilever barrel in the cradle and cradle cap elongation than 160
mm;
• Rear guide to the cradle box has been moved to a more assertive oboymennuyu part is made of bronze-faced, this design eliminated the quick coupling pipes with a breech;
• introduce additional lyuftovybirayuschie device cradles the neck (2 pieces), in lyuftovybirayuschih devices used rollers instead of the stops than excluded the impact of depreciation stops on the shaft to bias the guide cage and reduced frictional force in this compound substitution of sliding friction bearings;
• backlash-free use tsapfennye nodes with elastic rollers and working wedge, whereby the impact of free running spigots on accuracy is reduced;
• For automatic account crimps the barrel when firing at the muzzle of the pipe is foreseen mount reflector accounting device crimps barrel (CID).

Compared with the gun 2A46M accuracy 2A46M-5 increased by 15-20%, the total dissipation by firing rally fell by 1.7 times. Cannon in 2003 graduated from the municipal tests, in 2005, was adopted by the Russian Army and the series is on the Yekaterinburg artillery plant number 9. At the current time 2A46M-5 installed on all T-90A tanks rolling off the assembly flow "Uralvagonzavod".
2A82. Smoothbore gun oversized power with avtoskreplennym and partly shiny barrel 2A82 is completely redesigned, just outside identical with 125mm tank guns of the previous generation.
The achieved level of energy damn gun 2A82 allows significant an advantage over serial and developed by Russian and zabugornom counterparts. Muzzle energy 2A82 cannon muzzle energy is much more widely known gun Rheinmetall Rh 120/L55. The technical level of an advantage of the latest gun valued at 1,2-1,25 times. Particularly impressive are the values of the coefficient of metal use and the specific loading of the barrel — important features characterizing the design perfection.
T05BV UDP-1. As an extra weapon on the modernized tank paired with a conventional gun machine gun installation 6P7K PKTM 7.62 mm ammunition 2,000 rounds, also brand new remote-controlled machine-gun installation T05BV UDP-1 modular design.

T-90ms "Tagil": Firepower

UDP is designed for short-range self-defense, suppression and destruction of tank hazardous manpower (infantry) of the enemy at ranges up to 1500 m To ensure these tasks is quite enough gun caliber rifle. Because as the primary option provides control equipment 7.62-mm machine gun with ammunition 6P7K PKTM 800 rounds in a 2-stores UDP is mounted in the turret a bit behind the commander panoramic sight, that provide radial firing (UDP sector of fire is 316 °) . UDP skompleksirovana commander panoramic sight. It has two-plane stabilization. Vertical angles are pumping from -10 ° to +45 °. has a low-level TV sight, built-in OMS "Kalina". Managing UDP and can be duplicated as a commander and gunner. The signal from the sight of UDP is displayed on the main panel of the commander and gunner, with all this firing can be carried out and for which primary sighting system with the introduction of the respective thermal channels.
Obviously, installation UDP increases the cost price of modernization, but the developers of the modernized tank provides another "budget" option of additional weapons: the commander hatch at capacity for the machine gun on the swivel (two points) are. It can be mounted machine guns of 7.62 mm PKM 6P6, 6P41 "Pecheneg», FN MAG, or 12.7 mm 6P50 "Kord" and FN Browning M2. With all of this are provided by the following firing angles: horizontal — to starboard 102 °, to the left side 88 ° (with an additional installation point — 168 °) and from +30 ° to -10 ° vertically.
Implementation in UBM "Breakthrough" latest Russian developments in the field of artillery systems and ammunition provides modernized T-90 fire an advantage over all existing tanks, including the new «Leopard 2A7 +" (Germany), XK-2 (South Korea), «Altay» (Turkey ), Type 10 (Japan).
