Speed: Mach 4
Warhead 30 kg
GUidance: Inertial, Temrinal Radar and IR
Where did you come by those specs, Jeff?
Wikipedia lists Sky Sword II's range as 60 km, and I'm pretty sure it is only active radar guided, no IR homing... It is a BVR missile after all, like AMRAAM. [edit: sorry, didnt' see you meant TC-2A, which supposedly has an IR seeker and a larger motor... however has anyone actually seen the missile in service? An IR seeker and larger motor should be fairly obvious]
Also, a surface launch TC II would have far less range than an airborne launched equivalent.
The PLA's PL-12 (which incidentally does have a range of 100km, at least on the latest versions), which has been developed into the surface launched DK-10, required a redesign and addition of a large motor to even achieve 50km slant range.
The same goes for the sea sparrow, which I'm sure you're familiar with. Derived from the original AIM-7 with a range of up to 50km, the vanilla RIM-7 only had a useful range of 19km! It was only the ESSM, with its larger motor and redesigned fins, did it manage to achieve 50km.
I'd be surprised if a surface launched TCII is able to surpass a 30km slant range from ground launch, assuming they are not adding a larger motor like ESSM or DK-10.
But still, TCII will still be superior than sea chapparal, as even an unmodified TCII will have greater range than the sea chapparal's measley 10km, and active radar homing will provide better multi engagement.
TCII will be a good replacement and give Taiwan's la fayette's much needed short to medium range air defense. Will be better if they could install it in a VLS though, and if it was equipped with a booster for a true ESSM equiavlent. I suppose beggars can't be choosers (once the mantra of the PLAN of yesteryear, ironically!)
