If you read the suggestion, you would have seen that the tree was done in a blanket style, ex. it shows off everything Canada could get both unquie & C&P.
In addition, most of it is “licensed built,” so Canada built it themselves(making them unique variants) rather than just buying it.
That hasn’t stopped others like them from coming to War Thunder already.
The CF-100Mk 5 would join the other rocket-only jets, like the F-89D.
The CF-101 would join other “missile onlys” from the Sea Vixen F.A.W. Mk.2 that just dosn’t have any guns to the F-104S ASA that loses its gun if you take missiles.
The CF-104 didn’t have missiles, in RCAF service, but others who used it did and as far as I could find, no modification needed, hence the split, a semi-historical one with this possible as a “late” and a more historic one.
As for a gun:
Here are two photos showing it with a gun.
Did you look at the tree? I have all armed variants 3A/B, 4A/B and 5(& M) in the tree; and the Mk 6 is paper.
Kinda hard, when they already have two sub-tree with less than 1% of their aircraft, and no room for domestically operated UK stuff.
The Canadian tech has to fight 3 other nations for a spot, it’s more than likely nothing would come instead, due to the 5 line limt, mixed with the only 3 vehclies in a line per rank( at most 9, with 3 in a folder, more more like 6, and then unlees your making nonsense folders, it wouldn’t work)
And the reason why this suggestion exists is because we want treatment like that to stop, having our tech ripped across nations unable to be used in a line-up together. What you said is the worst case for Canadian vehicles, not the best, unless you have something against Canada.
