The 115mm U-5TS, or 2A20, is a smoothbore gun firing fin-stabilised projectiles and is installed in the T-62 MBT. It has no muzzle brake but is fitted with a bore evacuator and most installations are equipped with a light alloy thermal sleeve. Manual loading limits the rate of fire to about 4 or 5 rds/min but the spent propellant cases are ejected from the turret rear by a mechanism actuated by the gun recoil. The gun is used with two-plane stabilisation equipment.
The gun is effective out to a range of about 3,000 m and the length of the gun tube is 5,700 mm. The APFSDS round fired by the U-5TS can penetrate 300 mm of armour set at an angle of 0° at 1,000 m.
With the installation of the 9K116-1 system the T-62 MBT can fire the AT-12 laser-guided projectile.
Prime contractor for this laser guided missile system and its associated missile is the KBP Instrument Design Bureau. The first AT-12 projectiles had a single HEAT warhead but the latest projectiles have a tandem HEAT warhead to defeat ERA.
The latter round is designated the 3UBK-10M2 and has a maximum range of 4,000 m. The Russian name for the weapon system is the Sheksna.
This weapon has been manufactured by Royal Ordnance Nottingham for the Egyptian Army to replace existing barrels on T-62 MBTs or for fitment to new tanks (see separate entry).
It is also possible that licensed production of this 115 mm weapon has been undertaken in such countries as North Korea.
Production as required. Installed in T-62 MBT.
