I think everything that has to be said why the Super Hornet is not the best fighter for Canada, has been said (and obviously why the F-35 is the best option too), pointless me making any further comment about the pros and cons.
But there is one particular issue that hasn't had that much mention, and that is the ability to sustain, maintain and upgrade whatever aircraft is selected for 30+ years, at least somewhere into the 2050's.
The F-35 of course is an aircraft program that is going to see, at this stage, approx. 3,000 airframes manufactured into the early to mid 2030's and see those aircraft still in operations well into the 2050's.
You don't have to be a rocket scientist to work out that being a user in such a large pool of aircraft is going to see a massive industrial effort support those many thousands of airframes for a long long time, and it's not just support to keep them in the air, it's also the ongoing development and upgrade of the various sensors and weapons systems for many decades to come and to keep them relevant for emerging threats well into the future too.
The Super Hornet on the other hand, whilst yes as at today and probably for up to the next 20 years will have similar support, but what happens by the mid 2030's when the RAAF will have retired it's fleet and the USN will no doubt be in the process of retiring airframes? (some of which have been currently been in service for 15 years as at today).
The Super Hornet production line is still open, but it is on life support, currently being drip fed enough for another years worth of production every year.
But sooner or later that drip feed from the USG will cease and if there are no other foreign orders, well that will be the end of the line, the question would be, 'if' the Canadian Government did order Super Hornets (a mistake, but still...), when would an order have to me made by? Certainly a decision would have to be made in the next couple of years at the very latest.
If I remember properly the previous Canadian Government, (whilst it sat there undecided about ordering the F-35A in it's dying days), made an announcement that money would be spent on 'extending' the life of the current Classic Fleet for a few more years (another attempt to not having to make a decision and leave that decision for the future).
Roll forward to today, the current recently elected Canadian Government is probably still a couple of years away from making a decision, 2018? 2019? Beyond? Who knows!
Again, 'if' they did select the Super Hornet, more than likely they will be the last airframes off the Boeing production line, possibly somewhere from the early 2020's to the mid 2020's, if that was the case, you would expect those airframes to be in service for 30 something years, mid 2050's and beyond, maybe into the early 2060's too.
So what happens around the 2040 time period when all other users (currently RAAF and USN), have retired all of their airframes or are in the process of winding down operations and they are heading toward retirement?
It leaves Canada as the 'sole' or 'primary' user of that aircraft and in relatively small numbers too, sounds pretty risky to me.
If you look at the RAAF for example with the F-111C's, by 1996 the 'F' had been retired and the last ones, the 'EF' were gone by 1998, it became the sole operator of that aircraft, and we had planned to operate them till 2020, but of course that was changed to 2010, still if we had of operated them till 2020, we would have been the sole operator of a small fleet for 20 years!
Not suggesting that it's impossible to be the sole operator of a military aircraft, but when you are, it can become a rather expensive exercise to do so, and going it alone on future developments to keep that aircraft flying and more importantly 'relevant' too, can also be an expensive and risky exercise too, the risk is all yours and not being shared by many of the other operators too.
Super Hornets for Canada? Big mistake!
Anyway, just my opinion of course.
Cheers,
