The 2S35 Coalition SV is a relatively new twin-barreled mobile artillery system, possibly designed to replace the aging 2S19 MSTA-S self-propelled howitzer. According to Russia’s MOD, the system is equipped with twin barrels for an increased rate of fire. Two years ago, it was reported to be cancelled. However, last summer, the system continued testing with a brand new turret (the first version that was showcased had an enlarged MSTA-S turret). Due to the lack of information, it is not yet clear how the system’s design will give it superiority over existing artillery systems, or even if the system is practical at all (it will certainly weigh much more than all current self-propelled artillery systems). A naval version of the system is also rumored to be in the works.
