Reinforced Gun Barrel with Armored Casing Developed for Tanks in Russia

Russian engineers have devised a new design for a tank gun barrel with a thickened multi-layered casing. The development enhances the barrel's protection against fragments, climatic influences, and reduces the risk of deformation during firing. The patent was registered in the FIPS database in January 2026.

The submitted documents reveal that the prospective tank gun barrel features a two-section casing with a central spacer. The design includes screw-on attachments secured with stoppers and an additional section that ensures centering along the entire length of the barrel.

The casing is proposed to be thickened, with a multi-layered structure. Several variants use armor-resistant steel and reinforcing materials, including Kevlar fiber. A small gap is left between the casing and the barrel for temperature stabilization.

Currently, in combat conditions, the outer surface of the barrel is subjected to impacts from fragments, temperature fluctuations, and moisture exposure. Damage leads to microcracks and reduced accuracy. The new design reduces the risk of barrel bending, minimizes the impact of uneven heating, and extends the service life of the gun.

Interestingly, the casing includes technological openings for installation and removal. The central spacer can be made detachable — from two half-rings, to quickly replace damaged elements without completely disassembling the gun.
