Smoothbore
A smoothbore weapon is one which has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars.-History of firearms and rifling:...

 125 mm anti-tank gun.

Development

The 2A45M was created in the late 1980s at the Petrov Design Bureau at Artillery Plant Number 9 also responsible for the 122 mm howitzer 2A18 (D-30).

Description (Sprut-B)

The most distinctive feature of the Sprut-B is its Auxiliary Power Unit, which can propel the gun on relatively flat surfaces (up to 15 degrees slope) and at 14 km/h on roads. This gives the gun a measure of mobility on the battle field—although it takes 2 minutes to go from firing position to travelling position and 1.5 minutes to go from travelling position to firing position.

The gun features a crew of seven. During the day the OP4M-48A direct fire sight is used, at night the 1PN53-1 night vision sight is used. For indirect fire the 2Ts33 iron sights are used, along with the PG-1m panoramic sight. The gun can reliably engage targets 2 metres high at a distance of 2000 metres.

The barrel features a thermal sleeve to prevent temperature changes affecting the accuracy. The gun uses the same split ammunition as the T-64
