There were 32 SR-71s, 13 A-12s and 2 M-21s. That's 47 total I believe, making your figure off by about 300%, which incidentally is how much cooler the SR-71 is relative to the Mig, on account of it looking incredibly exotic and elegant instead of like a pointy sky tractor. Being faster is just icing on the cake.
Your figure of 300% is off by orders of magnitude for how much cooler the SR-71 is at 60 years of age than practically anything else that exists.
That's my point. The SR71 makes for a much cooler topic of discussion, but in a war, it matters how many planes you have. Even a thousand jets isn't really that much when fighting a country of millions.
