- Maritime strike, as anyone intended to invade Australia will need to come by sea;
- Has a precision long-range strike capability to defeat strategic target sets (sending the appropriate message);
As per my last post, this is what a F111 replacement will be required to do, as the F111 currently is the only fighter or strike aircraft we have which can carry a Harpoon and a Stand Off Missile (AGM 142).
Plus it can curise at Mach 2.5 and do over Mach 1 a few feet off the deck
Regardless I cannot think of an aircraft one could directly compare to the Pig, as there isn't really anything barring maybe a B1, so one has to just look at easy of transition, fleet commonality, easier integration with existing systems etc
