The 2S35 Koalitsiya-SV (Russian: 2С35 Коалиция-СВ) is a new generation of Russian-made self-propelled tracked howitzer based on the 2S19 chassis fitted with a new turret. It is a successor to the 2S19 Msta-S. It is also intended to replace ageing Russian 152-mm artillery systems.
The 2S35 was originally designed as a variant of the 2S19 Msta, consisting of a 2S19 chassis with modified turret, fitted with an over-and-under dual autoloaded 152mm howitzer.
The first demonstrator was completed in 2006.
