The 1st Guards Tank Army of the Armed Forces of the Russian Federation in Western Military District will order new 2S35 Koalitsiya-SV self-propelled artillery system for  trials.
Russian Army trials of new 2S35 Koalitsiya-SV self-propelled gun are expected to begin in 2017. Expected that 10 2S35 Koalitsiya-SV self-propelled guns will be delivered for 1st Guards Tank Army.
The 2S35 Koalitsiya-SV (coalition) is a new Russian self-propelled howitzer. It is a successor to the 2S19 Msta-S. It is also intended to replace ageing Russian 152-mm artillery systems. Currently it is one of the most capable howitzers in the world.
The first demonstrator was completed in 2006. This unique self-propelled howitzer had two 152-mm guns. It used a number of components from the previous 2S19 Msta-S. The twin-barrel Koalitsiya-SV demonstrator had a higher rate of fire than current artillery systems. It could fire at around 16 rounds per minute.
