苏联成功的试验了为台风号潜艇新设计的潜艇发射弹道导弹SS-N-20。这是由装在德尔塔级潜艇上的弹道导弹SS-N-18的基础上改进的。尽管苏联表面上同意遵守战略核武器限制协定,但他们在太平洋上试验的遥测数据却密而不宣。苏联在1981年12月份为了打靶试验,在太平洋中部划定了一个弹着区域。这次SS-N-20试验成功后又有几次失败了。台风号潜艇装载 The Soviet Union successfully tested the launch of the SS-N-20 ballistic missile for the newly designed submarine of the Typhoon submarine. This is based on the SS-N-18, a ballistic missile mounted on a Delta-class submarine. Although the Soviet Union ostensibly agreed to abide by the strategic nuclear arms limitation agreement, telemetry data they experimented with in the Pacific was very close. In December 1981, the Soviet Union demarcated a strike zone in the central Pacific Ocean for targeting experiments. Several times after the successful SS-N-20 trial failed. Typhoon submarine loading
