The B-21 Bomber will officially rollout to the public the first week of December: USAF

[MH.Yang]

For starter, the B-21's shaping is cleaner than the B-2 just by visual assessment which implies that the B-21's RCS will be even lower than the B-2's.

Please provide RCS data of B21. You can't use your feelings as evidence.

No please provide proof that B21 have no upgrade from B2 other than its 30% cheaper first, since you started it

Do not try this with me, pal.

Ever since the J-20 came out, this forum consistently have claims from the PDF Chinese cohort on its RCS which is supposedly on a par or even lower than the F-22 and F-35. All without hard RCS data. Just on Chinese 'feelings'.

Mr Yang only allow his feeling, he won't allow other to have theirs........

It's pointless to talk to him, all his post, either here or other thread, he had provided no detail nor evidence to support his claim, yet, he is the one that go around and ask people for claim.

 

[MH.Yang]

Well, I find these arguments too boring.

In fact, the answer is that we do not have any information and data of B21, and it is absurd to make any judgment now.

 

[jhungary]

I find Mr Yang post boring; he is the one that claim B21 is only 30% cheaper than B2, and then he said nobody know anything about B21........LOL Then how did he know? Umm, he must be a superspy.

If you say B21 is much better than B2 without any data and information, B21 is a 6G fighter, etc.

Of course, I can also say B21 is a cheap version of B2 without any data.

 

[mike2000 is back]

Oh now you work for US Department of Defence? How do you know how much B21 Cost to be exact?

B2 were projected to cost 737 million per in 1989, when they were in project state, which is the same state as B21 now, so either you can see into the future, or have insider knowledge as to how much B21 is going to cost the DoD to buy, you have proven shit bro.

You guys should calm down..I'm surprised you are debating so seriously about that Chinese dudes funny remarks. Its obvious that he is trolling and its normal since he's Chinese. So anything coming from US will be downplayed and slandered by them. Its normal since they see US as a rival/enemy so you dont expect them to factually appreciate your achievements do you? Lol
If this was made by a Chinese company, you can be 200% sure that there will be lots of threads here on PDF bragging about how advanced and sophisticated this new stealth bomber is and how it can bomb or destroy any country on earth without being detected etc etc lol .
So it's just normal sabre rattling. Don't take what some of them say about this sophisticated project seriously. They are still trying to build their own first stealth bomber. So wish them the best.

I never say anything, I said you should provide proof when you make the outrageous comment that B21 is only 30% cheaper than B2.

I still have not seen a single proof from you, yet you go up and down, left and right and ask for other people for proof. World did not work that way pal.

well, just pointing out the hypocracy of some member here......lol

Breaking Defense: Northrop Grumman has extensive experience in designing and maintaining low observable aircraft. What lessons learned is Northrop Grumman bringing to the B-21 to support sustainment?


Sullivan: The B-2 Spirit, which we designed and built in the 1980s, was revolutionary not only for the shape of the airframe but also the low observable (LO) treatments and coatings that were applied for survivability. These have set the standard for the last three decades.

Our advancements in LO were not without their challenges, however. At the time, the overwhelming focus of the build was the LO design; maintenance consequences of the design had not yet been fully realized. Early stealth aircraft have required extensive resources, including specialized personnel with unique training, and aircraft hangars and other facilities with narrow temperature and humidity requirements for both aircraft maintenance and storage of materials.

Today, with the B-21 Raider, our team has made maintainability an equally important requirement to stealth performance, and the results have been better than we could have hoped. Through the application of lessons learned on B-2 and other stealth aircraft, and the use of digital engineering techniques, not only do we have a design that has significantly improved over the B-2 from both a survivability and aero-performance perspective, we also now have a coating system that is as revolutionary in its maintainability as the original B-2 systems were in their stealth performance.

Furthermore, we’ve exceeded performance requirements.

The B-21 Raider: A Bomber That Is Both Low Observable And Easier to Maintain - Breaking Defense

Supportability issues that affected the availability and performance of early, stealthy aircraft are being addressed by Northrop Grumman on this new program.

The B-21 is much more advanced than B-2 and the first true 6G and ELO aircraft.

Considering the intent of 'stealth' and precision weapons is to deliver the minimum to achieve results that disproportionately outsize the efforts, that would be analogous to how little intellectual efforts does it take me to debunk Chinese claims. I do not need more than a few brain cells, and have done such little, to show the readers how the PDF Chinese cohort consistently misled and lied to the readers.

Verbally declaring some victory on the internet is an indication of retardation.

 

[patero]

we also now have a coating system that is as revolutionary in its maintainability as the original B-2 systems were in their stealth performance.

That's got to be the new ceramic based RAM referenced here:

No doubt there will be other cutting edge technologies incorporated, such as RDE (rotating detonation engines) at some point. I also wonder if they are considering a tanker variant for operating in contested airspaces.

Are we going to have Tim Cook on the stage doing the official unveiling.

I would love to see that guy from the Iron Man movie doing the unveiling. Justin Hammer he was CEO of HAMMER Industries.
