125 mm Modernized tank cannon 2A46MS for T-72 M2/ PT-91M Pendekar


2A46MS - tank cannon with a smooth bore mainly, modernization of the originally Soviet tank cannon 2A46. The 2A46MS cannon was originally designed for a Slovak modernized tank T-72 M2 with the aim of increasing 357; its combat effectiveness & # 357; and accuracy & # 357; stre & # 318; by. In addition to T-72M2 he also had export successes - Polish tank PT-91M Pendekar pre Malajziu.


Upgrading increases the likelihood of & # 357; hit with the first shot.
The modernization is based on the original cannon 2A46 with the following design changes:
- symmetrization of the butt structure of the barrel,
- by reducing the resistance of the loading brake during the movement of the projectile in the barrel,
- by shifting the axis of the loading brake below the axis mainly in the measuring plane,
- using two opposing gatekeepers and changing their position above the barrel axis


The upgrade has increased the likelihood of & # 357; impact compared to the original cannon by 23% (under Construction Constructor Defense)

Modernized 125 mm cannon 2A46 MS
The aim of the modernization was to increase the accuracy of firing the 2A46 tank cannon. The Trenčín company Konstruktta Defense, which was the implementer, decided to solve this problem by minimizing the muzzle disturbance of the cannon. In the first phase of development work, the conditions on TK 2A46 were analyzed in terms of mouth disturbance. Based on the results, an optimal solution for the modernization of TK was designed and implemented in order to reduce its mouthfulness and increase its accuracy. This was achieved by redesigning the brake reversing device and symmetrizing the design of the butt barrel so as to reduce the resulting torque action on the barrel during the movement of the projectile in the barrel. With the prototype of the 2A46 MS cannon under the designation YA1, mounted in the T-72 tank, comparative shooting tests were performed with the T-72 tank with the original 2A46 cannon. Based on the results of shooting tests, the probability of hitting the target (T-72 tank) was then evaluated with the first shot from the T-72 tank using TK 2A46 and 2A46 MS. The probability of hitting the first shot with the use of cannon 2A46 MS increased by 23% compared to the original TK 2A46, while effective cooperation with the fire control system, this value is still increasing.
