Re: PLAN submarines Thread II
Completely agreed! With the massive landmass, various kinds of terrain and a comprehensive network of air defense, their land-based ICBM is very secure. I would imagine it would be almost impossible for anyone to penetrate thousands of miles into China's air space while bypassing layers after layers of air defense to attack its ICBM sites, assuming anyone could actually find out the exact location of these sites...
And the same could not be said of the US or Russia? Guess which arm of the nuclear trident both those countries considers the most important?
Firstly of all, ICBMs are not the only means to deliver nuclear weapons. Stealth bombers, cruise missiles and SLBMs can all be used, and used in such a way as to give minimal warning and also create enough ambiguity as to who is launching the nuclear strike to make it a catch-22 situation for you if you rely too heavily on land based missiles that that first enemy nuclear strike is targeting, especially in a surprise attack. Provided you even have a chance to retaliate as a SLBM attack, launched from close to your shores, could give you minutes to respond.
Say a dozen SLBMs suddenly popped out of the middle of the Ocean and is heading towards your nuclear solids and mobile launchers, and you have potentially minutes to decide what to do before the enemy missiles hit before your forces can launch their missiles, just who do you launch against and what do you target?
What if country B launched against you knowing your automatic response is to lacuna against country A?
Even if country A brazenly launched the attack from its own silo based missiles, what do you target in return? Just their land based silos? Well most those are now empty, and their primary nuclear strike power is out at sea in SSBNs anyways.
You can launch at his silos, but you know that won't even come close to killing his nuclear strike capability. But since you don't have SSBNs, his nukes will kill the vast majority of your own, already very tiny in comparison, nuclear arsenal. What if the first strike is just a trick to get you to either waste your own missiles or allow them to be destroyed so he can launch a second wave at your cities, when you will be near powerless to respond on kind? Do you only limit yourself to just attacking enemy nuclear launch sites and risk leaving yourself at their mercy after your own nuclear arsenal has either been destroyed or expended, or do you just launch everything you got and take everyone to hell with you?
Those are all impossible dilemmas with no real correct answer, and if you don't have a nuclear trident, you force yourself to have to make that choice within minutes of finding out you are under nuclear attack.
What good SSBNs gives you is the two-fold insurance that firstly, all enemies would have no confidence that they would be able to kill all your nukes.
Secondly, it gives you leaders the luxury of time to figure out what happened and decide the best response over the course do days or weeks rather than hours and minutes.
Those are just some very basic examples of why a nuclear trident centred around a strong SSBN force is essential in establishing and maintaining credible nuclear deterrence.
