Well the dual engine argument in Canada saved I do believe only one or two aircraft over the entire career of the fighter. Which is why we never cared. The increased engine care and costs was not worth it.
We do need new fighters. And you can't use the. "not at war" now argument. Because when something reals out against someone with a more advanced fighter. We're fucked. It's to late to by them when we're already at war.
Dont pretend it can't or won't happen.
The current fighters are a joke even up north when we're watching for Russians. We don't have enough to o squat in all honestly.
