Editing First strike (nuclear strategy) (section)

===Increasing SSBN deployment===
[[Nuclear submarine|Nuclear-powered ballistic missile submarines]] (SSBNs) carrying [[submarine-launched ballistic missiles]] (SLBMs), commonly known as "boomers" in the US and "bombers" in the UK, are widely considered the most survivable component of the [[nuclear triad]]. The depths of the ocean are extremely large, and nuclear submarines are highly mobile, are very quiet, have virtually unlimited range, and can generate their own oxygen and potable water. In essence, their undersea endurance is limited only by food supply. It is unlikely that any conceivable opponent of any nuclear power deploying ballistic missile submarines can locate and neutralize every ballistic missile submarine before it launches a retaliatory strike in the event of war. Therefore, to increase the percentage of nuclear forces surviving a first strike, a nation can simply increase SSBN deployment and the deployment of reliable communications links with SSBNs.
