Wirklich die helle Lackierung, damit man sie auf dem Betonboden in Diego Garcia nicht sieht, haben nur wenig Hangarfläche da, gut die schwarze U2 musste auch immer schnell aus der Sonne damit sie nicht zu sehr erhitzt und Fehfunktionen riskiert

Warum die Air Force doppelt so viele B-21 braucht
Nach einer Studie des Mitchell Institute for Aerospace Studie könnte das alles noch viel zu wenig sein. In ihrer Analyse schlägt die Organisation Alarm: Die heutige US-Bomberstreitmacht verfüge nicht über ausreichende Durchschlagskraft. Dreißig Jahre aufeinanderfolgender Bestandskürzungen und das Versäumnis, die Flotte zu modernisieren, hätten dazu geführt, dass die US-Bombertruppe in erster Linie eine Abwehrtruppe sei, die nicht in umkämpfte Gebiete eindringen könne.
Doch mittlerweile ist ein Konflikt mit China eines der Szenarien, für die sich die USA wappnen will.

"Wir brauchen die B-21 so schnell wie möglich und so viele wie möglich, um der dünnen Bomberflotte zu begegnen und um in der Lage zu sein, Abschreckung und andere Operationen nicht nur gegen China, sondern auf der ganzen Welt durchzuführen", sagte Heather Penney, Senior Resident Fellow der Denkfabrik.

Die bisher vorgesehene Produktionsrate von bis zu neun Flugzeugen jährlich solle deshalb auf 20 erhöht werden.

Mindestens 300 Bomber seien insgesamt nötig. Zu den 75 Boeing B-52, die die USA weiter betreiben könne, brauche es folglich 225 B-21. Denn rund 45 Rockwell B-1 und 20 Northrop B-2, die die Air Force bisher im Einsatz hat, werden von der neuen Raider abgelöst.

National Defence: Defence Strategic Review 2023
Air domain immediate investment priorities

[...]

8.46 The Review has undertaken detailed discussions in Australia and the United States in relation to the B-21 Raider as a potential capability option for Australia. In light of our strategic circumstances and the approach to Defence strategy and capability development outlined in this Review, we do not consider the B-21 to be a suitable option for consideration for acquisition.

B-21 Raider’s First Flight Still Set For 2023 After ‘Power On’ Milestone (28. Juli 2023)
The first pre-production B-21 Raider stealth bomber has been successfully "powered on," according to manufacturer Northrop Grumman. The company also says that is still expecting the B-21 to make its first flight later this year.
Kathy Warden and Dave Keffer, Northrop Grumman's CEO and Chief Financial Officer (CFO), respectively, discussed the B-21 program during a quarterly earnings call yesterday.
In July 2019, the Air Force said that its goal was for the first flight to occur in 2021, but left open the possibility that the schedule could be pushed back. COVID-19, with its massive global ramifications, began to raise massive alarms in early 2020.

By early 2021, the Air Force said it was aiming for a Raider first flight by the middle of last year, which also did not come to pass. The current goal is to have the B-21 take to the sky for the first time before the end of this year.

"We remain on track for first flight [for the B-21] this year," Northrop Grumman's Keffer said during yesterday's earnings call, but stressed that this would still "depend on events and data."
There are also concerns about cost growth for what is already expected to be a multi-billion-dollar program. A global economic slowdown, triggered in part by Russia's all-out invasion of Ukraine in February 2022, is also a factor. As is ballooning inflation.

"I will remind you, we still have the risk factor associated with B-21 as we look at inflationary impacts," Northrop Grumman's CEO Warden explained during yesterday's earnings call. "In the [second] quarter [of 2023], we did receive notification that the DOD has allocated $60 million for B-21 LRIP [low-rate initial production] procurement due to inflationary impacts, and we expect that to be awarded later this year. But keep in mind, this only applies to the one fiscal year it's associated with, FY23 [Fiscal Year 2023], and we continue to work closely with the government on an effort to address the impacts of macroeconomic disruption."

CFO Keffer separately said that Northrop Grumman expected to receive a contract from the Air Force for the first lot of low-rate production B-21 sometime after the Raider's first flight, but it is unclear if the two events are directly tied to each other.

B-21 Raider begins taxi tests, a key step before first flight (26. Oktober 2023)
The B-21 Raider has begun carrying out taxi tests at Air Force Plant 42 in Palmdale, California, a key step for the Northrop Grumman-made stealth bomber before it can carry out its first flight.

A U.S. Air Force spokesperson confirmed the first B-21 bomber is now taxiing along the ground, but said no other details on its testing were available.

Confirmation of the B-21′s taxi tests came after a photograph of the bomber, taken from the rear and apparently showing it moving along a taxiway, emerged on social media.

First Photo Of B-21 Raider During Taxi Tests Emerges (25. Oktober 2023)

Bild
On Oct. 25, 2023, the first images of the B-21 Raider stealth bomber during ground testing outside of its Palmdale hangar have started to circulate online. The picture, posted online by a now deleted user on Reddit, shows the new stealth bomber apparently idle under its own power, with security flanking the aircraft.
Although we can’t fully confirm it, the photo appears to be authentic and not doctored, taken from a location outside the airport (?). Noteworthy, for the first time, the rear end of the airframe, including the exhaust, can be seen. In the case of the B-2 Spirit, the exhaust area was classified and no photo was ever released of it during the tests, but it appears that the B-21 was caught “off guard” and the exhaust photographed, although we can’t still see if the bomber has two or four engines.
