Number 2 airframe is under construction as first Flight is next year..


Good news concerning the second B-21 prototype, I take it that the first prototype is flying next year is due to Covid again?
No, Covid didn't really slow it down. It's due to the unexpected issues that showed up like the problems with the inlets. The December date was always a"if everything goes perfectly" date.

OK, I must have been thinking about the Spirit Aero article where they said Covid didn't slow them down because they moved people from the 737Max line to the B-21 line. Having said that, it still wasn't going to meet the Dec. 21 first flight date, also due to technical issues.

Sounds like article number 001 will see active duty if they are saying it will essentially be a production intent vehicle. Good for the USAF they need that aircraft operational ASAP.

It says quite a bit about their design and production planning.

Really interesting.
The graphics from above link (notice the distributed propulsion exhausts on the inner trailing edges as envisioned early on):

Really not interesting. They should hire other artist. This one even didn't understand how inlets do look like on Raider or made some research to find B-21 planform image at official site.

I think inlets are in fact somewhat masked/simplified as is the drawing in general.

"interesting" referred also to the content of the news report.
