Integrated Air Defense System. Scoop as a site has a leftwing bias so it does not surprise me and is a repository for press releases from all sort of groups large and small. The thing that amused me was that on one hand the authors were against an air combat capability and a frigate force on cost grounds and then on the other were advocating a series of medium range mobile air defence and anti-ship batteries around the NZ 15000km coastline. You guys know as I do that is incredibly expensive. South Korea's first six KM-SAM mobile batteries are going to cost NZ$650m. For that the Koreans would sell us sixteen FA-50 Block 20's, which would also save money in having to invest in a land based surface to surface missile system. Being multirole they would do a heck of a lot more.
