She's no longer an SSBN technically speaking of course...
The USS Michigan is now classified as a SSGN727 meaning: Sub Ship Guided missile Nuclear...
This in the most simplest of explanations, means that instead of once having the capability to destroy entire countries with it's SLBM's (Submarine Launched Ballistic Missiles) at a approximately an hour's notice, an SSGN is basically a total reconfiguration of the missile room in order to carry an advanced version of submarine launched "Tomahawk" cruise missiles instead... This creates a very formidable launch platform for launching many, many cruise missiles at the enemy from just about any location the submarine chooses to do so.
So your right JA, one day in the not too distant future this and/or any one of the other Trident submarines that were reconfigured for that, and other purposes which I will not get into because of it's classified nature, will indeed change the world forever!!! I personally would rather use those weapons platforms in their reconfigured capacity than having to use them in their original capacity because, no one will be left alive to pick up the pieces and millions will die!!!
However, let everyone know, friend and foe alike, that every Trident that still is configured to launch it's original payload of such destructive ordinance, will do it as commanded without any hesitation once every contingencey has been used to confirm the launch of such weapons -PERIOD!!!
It would be at any country's peril to underestimate the willingness, the resolve of such a system of machinery and men, from completing their intended task should the time come - which I personally hope never does!!!
I do however really like the newer variant, and it's awesome capabilities and would'nt want the USN to hold back at all in using the "puppies" that are available for "lobbing" at some of the "boneheads" out there who are looking for a fight!!!
Btw, I've got look for that pic I promised to post awhile back, and I will as soon as I find the time there JA but, thanks for reminding me about it ;)
Respectfully,
Henry
