That could mean anything. Technically, the moment they started producing the forgings for long-lead parts they started "building". Now five in final assembly would be something, but I'd bet everything I own that is not the case. Not even close.

Looks like I may have been incorrect. It would be nice if things are moving this smoothly.

Should've taken you up on that bet ;)

Still, it is nice to see someone being able to admit they might've been mistaken (and I agreed with you anyway)

Remember the old photo of the six B-2s in final assembly, probably the same for B-21.

exactly. that's why some old stuff hidden there for 25+ years finally saw light of day again

Like what…?
The code for the bathroom at Northrop Palmdale. Hint: it’s the same as my luggage!

Oh, they finally have read the comments.
Anyway, it's always good to have an official confirmation.

I like the way FK stresses USAF and USSF as key to winning the fight.

Below is an excercise I went through almost exactly two years ago guesstimating at production. I was figuring five completed by 12/21. Five may not be completed but perhaps I'm less than a year out? Certainly closer than it looked six months ago.

---

Here's a hypothetical exercise to see what B-21 procurement might look like based on the info available today.

Since we're talking integration and production of existing tech we'll assume there are mostly F-35 systems
and sensors on the new bomber. My point being that flight testing will be just that - flight and integration
testing. Not so much testing of new systems. The decade of F-35 testing will transfer to B-21.

Here are some examples of possible B-21 systems that might be reused from F-35


Dry version of F135 engineP&W listed as Sub for B-21
CNI Avionics on F-35NG - This includes MADL and sensor fusion. B-21 talks cleanly w/F-35.
AESA Radar on F-35NG
DAS on F-35Originally NG but dropped for Raytheon starting in 2023. Let's hope they fixed the lens problem or perhaps the USAF will specify the change to Raytheon?
EOTS from F-35LM - not listed as a supplier but doesn't the USAF own the technology?


Could they use large portions of F-35 code for B-21 since they are working on Block 4 already? Perhaps someone here knows?

If the stars align, maybe flight testing will go "head-spinning-ly" quickly and they move to building operational
air vehicles within two years. With the recent news concerning production funding in '22 it leads me to believe
the USAF wants to accelerate the completion of the EMD program.

With all those caveats, maybe the next few years looks something like this.

In Q1 2021, by historical reference, we expect roll-out and ground testing to begin since 1st flight is Dec '21.
This would mean that NG keeps all AV's under wraps throughout 2020.

AV-1 or AV-2 first flight in December 2021. AV-2 through AV-5 leave for Edwards throughout 2022 as they are finished.
Block 10 build is locked down in 2021. I believe I recall seeing that the first lot is development and consists of 5 air
vehicles so the math works. USAF projecting procurement funding to begin in '22.

Production increase from 2 to 3 air vehicles for 2022

During 2022, B-21 begins operational training as Block 10 air vehicles become available and are
flown to Edwards throughout the year.

It's a very interesting that procurement spending is projected for '22 - '24. These are most likely
long lead time purchases but the big $$ makes me think they are planning for early completion
of the EMD contract. This $$ allows them to finish the EMD contract in FY2024 w/all 20 bombers
completed and begin production of 8 bombers per year starting in 2025.

Production increase from 3 to 5 for 2023



Procurement $ in BudgetDev $ in BudgetBy DecemberAir Vehicles CompletedBlock No.Production Lot

It's been mentioned that FRP target is 8 bombers per year. At ~$700M each that's $5.6B per year. If you
add the '22-'24 procurement $$ you get $5.9B. That provides the budget for qty 8 bombers to be
purchased in 2025 w/a budget of ~$5.9 each year after. A squadron per year.

Production increases from 5 to 7 for 2024.

IOC sometime in 2025 with at least 8 bombers and one trainer. With this accelerated EMD contract
completion there could be almost twice that number. This ends the EMD contract.

Production increases from 7 to 8 for 2025.

$5.9B2028AV-45 through AV-5220FRP-4
$5.9B2029AV-53 through AV-6020FRP-5


In my exercise, best case scenario is 57 bombers by 2030. Six operational squadrons and a training
squadron. These are huge procurement numbers. No wonder the USAF wants to stop funding the
B-1 asap. Maybe they're speculating that the external threats will grow significantly between 2030
and 2040. In the mean time, they can save the B-1 upgrade $$ for B-21.
We will not have until 2030-2040. Other faster options need to be considered. ASAP.
