I can understand B-2s, but sending in B-52s and even B-1s into chinese controlled airspace without escorts is suicide.
natchiket, b52s/B1s can be used v.effectively to launch LACMs from long range. No need to go close to chinese airspace at all. For example B52s launched lACMs well in advance of H-hour during Iraq I.
You can carry out SEAD missons using bombers but who's going to take care of the legions of flankers the PLAAF can throw at you. In the absence of F-22s and F-15s that job falls on the SH. And the USN would not be buying 460 of them if it wasn't up to the task.
A) The flankers etc will be handicapped if C3 nodes are down (which will be the v.objective of stealth, tlam, bomber strikes). in case of iraq, the whole network was sufficiently degraded within minutes of H-hour. Tells you something. SA really suffers and consequently fighter assets can't be used optimally. Flankers are on the backfoot.
B. why do you think there will be "an absence of F-15s/F-22s"? They can easily fly in from Kadena, Misawa and even Osan. Plus the chance of basing them closer in japan/korea, even taiwan is v.probable.
Admittedly shornets will be involved in tangling with the degraded flankers. it'd be a terrible waste otherwise. My guess is in the initial stages they will stick to providing CAP and cover for the CBGs which will launch TLAMs in massive quantities. Flankers will find it v.difficult to spot the CBGs (esp. if chinese C3 nodes have been disabled at least to some extent), if they do, then of course they have to deal with the shornet bubble.
