To replace the CF-100 Canuck and CL-13 Sabre, Canada procured sufficient units for five squadrons of CF-101 Voodoo, eight squadrons of CF-104 Starfighter (later reduced to six, most were sold to other NATO nations) and later two squadrons of CF-116 Freedom Fighter (most of the 200 produced were mothballed and later sold).
Now, I appreciate this is contrarian-bait, since Canada would need a POD that allows it to fly obsolete NORAD/NATO aircraft until about 1965 and one that allows for more expensive twin-seaters for the NATO strike role.... but... 1963, the RCAF orders 150 x Phantom II for twelve squadrons to cover NORAD and ETO. The last aircraft is delivered just before Trudeau gained the PM's seat in 1968.
Now, looking at how Britain, Israel, Germany and others used the Phantom well into the 2000s (Greece retired theirs only this year) and considering that Japan and Turkey still use the Phantom today, and how parsimonious the Trudeau and following governments were on defence spending, how is the CAF's combat aircraft procurement impacted into the 1970s and beyond.
I assume for one we'd not see the CF-188 buy in the 1970s and 1980s. Instead, we'd likely update the Phantoms, and buy up second hand aircraft from other powers (remember, the second batch of CF-101 were used USAF models).
So, when would the CAF retire its Phantoms? Presumably the first batch would go with the end of the ETO deployment with the close of the Cold War in the early 1990s? What would replace the Phantom, likely in the late 1990s? The Super Hornet is available from 1995 onwards.
