So what are you’re really saying? Due to circumstances beyond RAAF control our classic Hornet fleet are not deployable and needed to be replaced a long time ago because of need to be managed to the degree you are stipulating. Would the RAAF be in a position to send any fast jet aircraft if we had not replaced F111 with Super hornet?
USMC F/A-18C seem to be doing just fine
That is not what I or anyone else has said, though you seem to want it to be the case for some reason.
Any ageing fleet needs to be managed through to it's life of type. That is not a difficult concept to grasp, surely?
The fact is that Hornets have what I believe is described as a fatigue life expiry index figure or similar. Their effective life ends when they reach this figure and the entire fleet is very close to reaching this figure. Their effective life (as a fleet, rather than individual airframes) is now being measured in years, rather than decades as is the case with Super Hornet.
Deploying Hornets to Iraq to do a job that the Super Hornet can do better, achieves nothing more than using up that remaining fatigue life at a far faster rate than planned which WILL result in RAAF having to spend far more cash than planned to extend their lives (as Canada seems to be intent on doing) or forgoe airframes and reduce the overall Hornet capability much quicker.
Do we NEED to do either of those things? No. We have a more capable asset available and deploying it won't have the overall impact on RAAF that deploying Hornet now would.
If a significant enough operational requirement dictated it, the Hornets of course would be deployed.
The USMC F/A-18C/D aircraft are between 5-10 years younger than RAAF's F/A-18A/B fleet AND they ARE being replaced from 2015, whereas our Hornets are to start to be phased out from 2018, ie: nice way to reinforce the point I'm making, so why you pretended not to understand it in the first place is beyond me.
Consider it this way if you're still having trouble understanding this decision.
Army has F-88A2 rifles (Super Hornet) and F-88A1 rifles (Hornet) in-service and both will be replaced by the F-90 (F-35) soon enough.
Under your apparently preferred option you'd see Army take F-88A1 overseas instead of F-88A2, the newer more capable design, for some baffling reason...
