二、潜地导弹水下发射试验潜地导弹武器系统在完成了陆上发射台、陆上发射筒的飞行试验后,进入了在潜艇上进行水下发射固体导弹的飞行试验阶段。该试验分3步进行:在常规动力潜艇上进行潜地导弹水下发射试验;在导弹核潜艇上进行潜地导弹水下发射试验;在导弹核潜艇上进行潜地导弹定型试验。1.先期准备60年代末,为适应导弹核潜艇发射潜地导弹试验的需要,中央军委决定,由海军试 Second, the submarine launch missile test Under-ground guided missile weapon system in the completion of the land launch pad, land launch tube flight test, entered the submarine underwater launch solid-state missile flight test phase. The test is carried out in three steps: underwater missile launching test on conventional power submarines; underwater missile launching test on missile nuclear submarines; and latent missile test on missile nuclear submarines. 1. Preliminary preparations In the late 1960s, in order to meet the needs of the missile submarine to launch a potential ground-launched missile test, the Central Military Commission decided that the naval test
