2S35 “Koalitsyia-SV” experimental vehicle, early stages
Background:
Originally, the vehicle was developed as a variation of the 2S19 “Msta-S”, a self-propelled artillery piece introduced in 1989. Later, a decision was made to create a completely separate vehicle, thus initiating the development of the 2S35 “Koalitsiya-SV” in the mid-2000s as part of the Armata project.
In 2002, the first phase of development of the 2S35 “Koalitsiya-SV” began at the Burevestnik Central Scientific Research Institute in the city of Nizhny Novgorod in response to the more advanced self-propelled artillery pieces being used by NATO member countries. The 2S35 “Koalitsiya-SV” was designed as a self-propelled artillery piece for tactical purposes, targeting tanks, structures, strategic points, non-strategic nuclear weaponry, and counter-battery operations — a term designated for weapons aimed at retaliating against other self-propelled artillery pieces, such as tank destroyers. In 2006, a test bed was presented featuring two 152 mm 2A86 cannons mounted on the chassis of an T-72B model equipped with a ChTZ V-84A engine and an experimental turret.
The name “Koalitsiya” refers to the adoption of two 152 mm 2A86 cannons, a term literally meaning the union of two weapons. The idea of twin 152 mm cannons remained from the design phases in 2002 until April 8, 2010, when the dual-cannon concept was abandoned, though the name has been retained to this day. On May 9, 2015, the 2S35 “Koalitsiya-SV” was unveiled for the first time at the 70th anniversary celebration of Victory Day in the Great Patriotic War in Moscow. In 2018, 12 of the 2S35 “Koalitsiya-SV” units produced were still undergoing testing, and in 2020 and 2021, a contract was signed between the Ministry of Defense and UralVagonZavod for the vehicle’s mass production.
However, in 2023, the Armed Forces command announced that the 2S35 “Koalitsiya-SV” was still in the testing phase. Later, on October 20, 2023, the start of mass production was announced, thus concluding the testing phase and confirming the vehicle’s adoption, now equipped with a single 152 mm 2A88 cannon on the Russian Armed Forces.
