Photo galery of a 420mm 2B1 Oka Self-Propelled Gun-Mortar, 2B1 Oka (Russian: 2Б1 Ока) is a Soviet 420 mm self-propelled gun. 2B1 is its GRAU designation. An experimental model was ready in 1957. Its chassis (Object 273), was designed and built by the Kirov Plant. Its 20 meter barrel allowed it to fire 750 kg rounds up to 45 km. Due to its complexity of loading it had a relatively low rate of fire—one round every five minutes. Field tests showed various drawbacks of the entire design (the recoil was too strong for many components: it damaged drive sprockets, tore the gear-box away from its mountings, etc.) and the sheer length rendered it incredibly difficult to transport.

420毫米2B1 Oka自行火炮迫击炮是苏联在1950年代开发的实验性火炮系统。它旨在远距离发射核弹,最远可达 45 公里。炮迫击炮安装在改装的T-10重型坦克底盘上,有六名乘员。2B1 Oka具有非常大的口径和非常低的初速,这使得它难以瞄准并且容易受到反电池火力的攻击。迫击炮还具有非常高的后坐力,对底盘和机组人员造成了损坏。2B1 Oka从未被苏联军队采用,只制造了两架原型机。该项目于1960年因其不切实际和过时而被取消。
