Soviet 2S7M Self-Propelled Gun The 2S7 Pion ("peony") or Malka is a Soviet self-propelled gun. "2S7" is its GRAU designation. It was identified for the first time in 1975 in the Soviet army and so was called M-1975 by NATO (the 2S4 Tyulpan also received the M-1975 designation), whereas its official designation is SO-203(2S7). Its design is based on a T-80 chassis carrying an externally mounted 2A44 203 mm gun on the hull rear. It carries 4 203 mm projectiles for immediate use while the remainder is carried by another vehicle and it is capable of firing nuclear ammunition of the same caliber. The gun has a range of 37,500 m but the range can be extended to 55,500 m by using RAPs (Rocket Assisted Projectiles). The Pion has also been the most powerful conventional artillery piece since entering service in 1983.
