    But also, how far can low light sensitive cameras see into the sky? Maybe a couple miles with some sort of telescopic optics? The F35 can attack from beyond visual range using its 100 mile range radar system.

      Up to the horizon (and actually slightly past due to lensing). The setting sun is a perfect example. Sure, it’s brighter than a single fighter aircraft, but as long as you have double digit individual photons to work with the game hasn’t changed theoretically, and light collection technology is right around perfect at this point.

      Continuous cloud cover messes up that calculation pretty good, though. If this kind of system was seriously deployed today we might see pre-WWII tactics and strategies coming back to exploit that. In practice, sensor fusion in all kinds of bands is the name of the game, and what will probably make stealth aircraft obsolete eventually.

        Sky coverage is just a matter of replicating one telephoto unit a couple hundred times or whatever to cover the horizon. Clouds are a game-breaker in the optical frequencies - when they’re there.
