How submarines launch ballistic missiles without blowing themselves up

Submarine-launched ballistic missiles utilize an innovative 'cold launch' method, setting a new global standard for safety. This technique propels missiles via high-pressure gas, preventing the ignition of rocket engines inside the submarine. Originating from Cold War developments, it enables launches from underwater, significantly bolstering nuclear deterrence and the safety of vessels and crews. Modern SLBMs, like India's K-4, integrate this essential technology.
