Has Taiwan already recieved 2 Kidds??well that's news to me.I think they launch an early variant of the SM-2 which has a range of around 70kms(SM-2 Block2??) with limited anti-missile capability.From what Ive read,the Kidds are good multi-purpose platforms,but I don't think they are stealthy by any means.They have considerable RCS.Ive read that Taiwan is planning upgrades on a lot of it's frigates like the French built Kang Ding class & American origin OHP class frigates-but these type can't carry anything more than a 16 or 32 cell launch system & they also don't have advanced radar & command systems like the AEGIS or APAR.So their ability to fully use the SM-2 will be stunted.Those ships will probably mount the ESSM medium range SAM & maybe even anti-submarine rockets.
