(Washington, D.C.) Almost nobody knows where they are at any given time, yet nuclear-armed ballistic missile submarines quietly patrol dark domains of the undersea realm in strategically vital waters around the globe, bringing the prospect of unprecedented destruction upon potential enemies -- all as a way to keep peace.
Undersea strategic deterrence, intended to ensure a second, retaliatory strike in the event of a catastrophic nuclear attack upon the US, ultimately relies upon the accuracy, resilience and functionality of the Trident II D5 missile. Accordingly, missile tube construction, fire-control technology and tests shots of the nuclear weapon are intended to help the Navy construct and prepare its new Columbia-class submarines on an accelerated time frame.
