Hmmmm....interesting thought....Lord Jim wrote:They could always try to redo the Arrow for the 21st century, or keep the CF-18s going for as long as or longer than they kept the CF-101s around and join up with the UK and see what comes out of "Tempest". Frequent trips to the "Bone yard" would provide many spares and a number of airframes will be coming available for stripping in the next few years. Being serious they need to avoid being pressured into a purchase of the F-35A
Get the Canadians involved in Tempest.
Problem is its too far away...so...
Let the Canadians squeeze all of the life out of the F-18C's they've got remaining and the Aussie ones....but....fill the gap in with ex RAF T1 Typhoons from 2025 onwards, there are lots of T1's and 2 seaters available. The UK could bring forward some F-35B orders to cover or do as the German's are doing and order a few more T3's (and keep the production line open longer..)
End result Canadians are covered for fighter cover to 2035, Boeing not involved, Canadian involvement in Tempest and a Canadian order locked in, UK either gets some F-35B's earlier or additional Typhoon T3's.
