I'd take what you see on 4 corners about military matters with a grain of salt. I seem to remember a beat up on the replacement of the F111 with the Super Hornet, a decision both Air Force and the Government now seem very happy with. I recall Labor being up in arms about it until they got into power, were briefed on the project, and then went very quiet. It's very easy to find people with an axe to grind who are against any major capital acquisition.
