A couple of things to remember here is that one, if you are going to keep any type of AAW capability you have to be maneuverable, a big honking RO-RO, or supply vessel is about as maneuverable as a pregnant yak. Secondly if they do away with the 280's before they get the JSS in place then they lose C & C platforms. Yes they can transfer some of those tasks to the CPF but they were never designed with C&C in mind. Also they could possibley try to refit the CPF for SM2 for that "Reach out and touch you capability" but RAM type missiles just don't have the range. Look it up in Janes. Now if you had the CPF Air radar with 280 fire power you could be looking at something there. Just my thoughts. If you have something to add please do.
