1. You don't have to overfly the SAM belt, but you still can be engaged by the SAM belt.
of course the stealthy flying wing doesn't have to worry about this.
Flying very fast and very high VLO shortens the range at which the SAM can effectively engage you, it widens the belt in which your plane can fire your stand off weapons but the SAMs cab't effectively engage your planes.
fixed it for ya (see how those things are interchangeable?)
In this case, being able to out run them by a comfortable margin,
Did those silly Chinese remember to build Gen 5 fighters but forgot to equip them with forward aspect BVR missiles? That is so like them!
And how comfortable is comfortable? if your bomber is pushing mach 3 with Afterburner that can be seen from space, and a Chinese fighter is flying at mach 2, how comfortable is it going to be? And if thats not comfy enough? Just how fast does our B-70 have to fly? Mach 4?
say sustaining a speed twice as fast as the figters, would give you much greater leeway to avoid the fighters, or to exploit any holes that the current of battle might open in the energy fighter screen.
Again everything this modern B-70 can do, the B-2 can do already, and surely the Next Gen bomber will do even better if it relies on stealth and sensors.
3. I am sure China knows this perfectly.
I don't doubt that, so why would they try to make a bad strategy work? Can they not read a map or even a book and learn from the USSR? What makes us so certain we will bankrupt them like the USSR? I mean China hasn't exactly copied the USSR in the global economy? What happens when China doesn't construct these massive SAM belts and thousands of fighters because it has nothing to fear from a Mach 3 bomber that can be seen from a long distance blundering into a wall of stealth fighters that will shoot it in the face? Not only that but does China construct all this when it can see B-70s coming from forever away anyway? What scares the Chinese into feverishly buying 21st century technology to combat 1960's tech? What if the Chinese Just decide to have patroling fighters and AWACs style aircraft rather than massive SAM belts and ground radars? what if instead of 2000 J-20s they get like 100 and say "thats fine" We spent a small fortune just to make them spend a small fortune and they weren't scared enough to take the bait. We have a lot of white elephants though.
What if SAC had 100 B-70s when they switched to low level penetration, thus totally negating the B-70s only advantages? Speed and Height? And why would we think the 21st century Chinese couldn't accomplish the same feat the Russians pulled off in the 1960s?
Every attribute you give our new B-70 is the same thing we can get with a VLO flying wing, except the break neck speed, which it doesn't need to accomplish the exact same thing and it doesn't have to guzzle fuel like i do Jagermeister when my football team loses while im on shore leave. the slower VLO airplane makes up for lack of speed with more fuel efficiency and room for weapons and sensors and electronic countermeasures and the ability to hang around in case other targets show up, and the enemy has to devote more resources just to find it.
The entire premise is based on the idea that with enough Height and speed you can't be hurt in numbers that matter but a lot of folks here have already pointed out that not only is that not the case, but it hasn't been for some time now.
