And your flying T-34 gets slammed by a BVR missile before your Mark I eyeballs can even see a target.
That’s what radar and IR sensors are for, track threats like the BVR. Hopefully, I’ll be able to hit the chaff/flare buttons (unless it is done automatically) before it gets too close. I’m just saying that if need be, we could do it with the power of a Commodore 64 that is hardened and more proven. Being economical and using off the shelf proven items does not mean going up there with nothing.
