Do countries that operate strategic bombers (USA, Russia, China) generally escort them with fighters? I know that Russia has had fighters along when it's sent bombers out near NATO countries at times. How might the conops evolve with stealth aircraft? If USA were to strike a "near-peer" adversary's integrated air defense network with stealth bombers (B-2 or LRS-B in the future), do you think they'd send along some F-22s or F-35s as escorts? Or is the whole idea of fighter escorts for heavy bombers an outdated WWII concept?
if you send an escort with bombers your chances of detection go up as there are more objects in the sky that can be detected by a variety of systems.
even in the days of SAC the bombers went in without escorts - and from the Berlin Wall on, the fast penetrators (Canberras, B45 Tornados etc ) went in solo testing Soviet detection systems due to the issue of discretion being better than sending a loud capability message
its really about when you are doing it
eg the whole purpose of the early days of an air war is to delaminate the enemies systems as much as possible to take control of the air
taking control of the air means fighters can go plinking and strike aircraft (including bombers) can operate with relative safety and impunity
if the enemies air defences have been delaminated, destroyed, then air superiority means that escorts become more and more redundant
think about all modern warfare events since Libya '86 - they have all been about precision delamination of the enemies sensor grid, their GBADS and their local air.
heavy bomber escorts basically died as a concept from the korean war on....
