How many missile tubes should an SSBN carry?

Is there an optimum number of missile silos for a ballistic-missile submarine?

About sixteen is proposed as a useful reference point, depending on deterrent requirements, missile payloads and how many boats remain at sea.

The argument treats tube count as part of the credibility and survivability of a deterrent force. Trident D5 and Ohio-class capacity illustrate how missile numbers, payload assumptions and redundancy affect the comparison. The numerical examples are the discussion's simplified assumptions, not a statement of actual deployed loadouts or targeting plans. A larger boat is considered more attractive where only one submarine is normally on patrol. Different national requirements can therefore favour different tube counts. A short continuation stresses that preventing unauthorised control demands particularly strong safeguards in nuclear systems.
