Replaced the Sunderland!
IIRC a P-3K eng told me that they got the new wings off the end of the ROK P-3 production line.
The spams obviosly don't know how to produce a new MPA. Surely it would be better to buy some 30 year old 737's, "zero life" the airframe, put new wings on and then get a few different companies involved to complicate the proccess, then drastically reduce the order just to keep within budget. They haven't even renamed it yet! How about MMA 2012?
