I really do not know much about either aircraft but from what I can tell the only real capability the B-2 has over the Bone is stealth and nuclear. There are less (according to af.mil) 20 Spirits vs 60 Bones. No doubt both will be gradually be phased out by the Raider but the B-2 might be phased out faster because there are few of them and that they're stealth maintenance requirements are significantly high.


One advantage that the B-1B has over the B-2, B-21 and of course the B-52 is being supersonic.
While what you say makes some sense, unfortunately (IMO) it seems that the plan is exactly the opposite - First retire the B-1B's and only later on retire the B-2s, all replaced by the B-21 obviously.
“Active stealth” is what the ignorant nay sayers call ECM and pretend like it’s new.

The B-2 is our only penetrating nuclear capable bomber, which is far more important than supersonic dash, with conventional weapons. Maintaining our nuclear capability will take precedence, as we will still have a lot of conventional capacity.

Thanks, great video. He seems to predict my own modest expectations. Basically the B-21 with its more advanced LO, will have more avionics and sensor capacity to operate alone and forward of the F-35. Whatever the F35 has, the B-21 will expand and improve upon. We'll probably be blown away 10-15 years from now as its abilities rise to the surface. Visually its an absolutely fantastic platform.

Exactly, the B-21 may have overlapping mission sets with the F-35. sorta like a Heavy SEAD/DEAD package, and with the immense fuel capacity it could be an orbiting SEAD sentry and just destroy any SAM site that goes online over a wide area.

after all the program name was “long range STRIKE bomber” so it may have tactical roles and not be limited to strategic roles

What???? B-21 is way more threatening than F-35.

Not only SAMs but it also threatens Chinese conventional BM and their launchers.

With its proposed numbers it will be able to fulfill the missions for both the nuclear triad and conventional tactical/strategic strikes. Going forward the potential for nuclear strike missions will grow.

Yes, what you say makes sense.
And stealth is indeed better to penetrate enemy airspace than supersonic dash. And like you and others said, the B-2 is nuclear capable while the B-1 currently is not.

However, none of the older aircraft (B-1 or B-2) will be retired until there's enough B-21's around, will they?

There's no plan to retire any B-1B/B-2, until there are lots of B-21s in service (much like the F-22/NGAD plan).

Would you expect NG to say anything else? They have to keep their stockholders happy.

Honestly, the US needs to get the numbers up. If, it is going to be able to afford the B-21.... :|


So, maybe they should sell the B-21 and maybe not just to Australia!

If only, that would be great. Just what's needed. Unfortunately we can expect US industry to set up shop to produce the barest minimum to maximize profits, and fail to even meet those expectations.
