The plan is to get 100 odd stealth multi role strike fighters, and to pair them along with no less than a dozen Growler EW aircraft (alongside our 6 Wedgetail AWACS). Thats 6 x F35's per Growler, and one AWAC per 12 x F35's.
More than enough air power to ensure air superiority against an attack from anyone other than a concerted and sustained attack from a super power (like China or the US).
Who would want to fly over & attack us anyway?
I still say our sub fleet (what ever we get) will be our prime defence asset. The rest of it is just toys for boys.
I mean WTF do we need 70 ton Abrams tanks for?
Good air defence missiles & some decent subs & we're ok. Except if China or the US come knocking. If they do then just lower the draw bridge, we're cooked anyway
