Precisely. It needs to be pointed out that if the Navy hadn't been able to go this route with conversion of the 4 Tridents, Bush, who is deeply steeped in unilateral nuclear disarmament pledges to the Russians and Chinese, would have been compelled to dismantle them entirely.
Poisoned fruit from his "Treaty of Moscow"...even though the Ruskies are NOT dismantling their SS-18s as was expected.
This was a way to keep the "assets" from going into the boneyard. They can actually be refitted back to strategic boats relatively painlessly...removing the "quad-pack" inserts in their tubes, and replacing them with the original Trident missile capsule.
It would be interesting to see if the fire-control systems original to the Trident aren't being left for reserved future use...or if the new systems added haven't merely had that option as a "two-fer". I doubt you will see anyone actually admitting to that...and likely you will see some professedly knowledgeable submariner deny it outright and stoutly too.
Can't let it slip to the enemy what our REAL capabilities are to restore strategic strength are.
But no matter how much spin is put on this, knowing the mindset of the Chicoms and the Russian coms pretending to be nationalists (Putin) they likely aren't buying the spin.
