re: PLAN Type 052 Class Destroyer
a Billion $ Vessel armed to the teeth with .50 cals.. now that's an idea.
seriously the french has the right idea for colonial defense. cheap low cost small ships. essentially US has the same mission, just don't want to admit it. but is able to afford bigger ships.
Uh...actually, from my perspective, no.
The billion dollar vessel is armed to the teeth with modern, state of the art anti-aircraft missiles, anti-surface missiles, torpedos, helicopters, advanced radars, advanced sensors, a 5" or other large caliber dual purpose gun, and a very efficient propulsion system. It's primary mission is war at sea, ASW duties, task force escort and protection, etc. Not "colonial" coastal duties.
If you are talking about the LCS, well, it is not a billion dollar vessel. But it too is not there for "colonial coastal" duties. It is also armeed with state of the art weaponry (including most of those mentioned above) and sensors for warfare in the litorals against submarines, other surface combatants, mine warfare, and also escort duties where a lightly armed corvette would not be able to perform all of those duties. The LCS is secveral hundred million a pop.
Either way, they also have several .50 cal machine guns, and perhaps a couple of 25 or 30mm autocannons for...as I stated, very close in self-defense against borders and terrorists.
Quite frankly, what I was posting about has nothing to do with coastal patrol vessels, or small corvettes. It has everything to do with making sure a simple, asymetrical threat does not damage or destroy a billion dollar, or mulit-hundred million dollar vessel.
And if you want to speak of the French, their Horizon and FREMM vessels are also high dollar ships, yet contain the same types of close in weaponry I mention for the same reasons...so your "french" analogy, when compared to the same type ships, simply doe not really apply either...at least not today.
As I said, such defenses are becoming essential for all such vessels, including IMHO, the Type 052C/D ships this thread is about..
