Sprut anti-tank gun
2A45 and 2A45M are the respective GRAU designations of the Sprut-A and Sprut-B (Russian for octopus or kraken[1]) Soviet smoothbore 125 mm anti-tank guns.
Development
The 2A45M was created in the late 1980s by the Petrov Design Bureau at Artillery Plant Number 9 (OKB-9), which was also responsible for the 122 mm howitzer 2A18 (D-30).
Description (Sprut-B)
A feature of the Sprut-B is its integrated engine, which can propel the gun on relatively flat surfaces (up to 15 degrees of slope) and at 14 km/h on roads. This gives the gun a measure of mobility on the battlefield. Changing gun position from travelling to firing takes 90 seconds; the reverse takes two minutes. Such guns are known in Russian as "self-moving" (самодвижущиеся) in contrast to self-propelled (самоходные), and outside of battle it is towed by an MT-LB.
The gun has a crew of seven. An OP4M-48A direct fire sight is used in daylight, and a 1PN53-1 night-vision sight is used at night. For indirect fire, 2Ts33 iron sights are used, with a PG-1m panoramic sight. The gun can reliably engage targets two metres high at a distance of 2,000 metres.[2]
The barrel features a thermal sleeve to prevent temperature changes affecting the accuracy. The gun uses the same semi-fixed ammunition as the T-64, T-72, T-80, and T-90 tanks.
With the addition of the 9S53 laser fire-control system, the gun can fire laser guided projectiles such as the 9M119 Svir or 9K120 Refleks.
Ammunition
The gun uses the same ammunition as the D-81 series of guns used on the T-64, T-72, T-80 and T-90 tanks.
