B-21 menja obe letelice tako da 90-100 kom mora biti na osnovu zahteva USAF posle 2030.

Koliko sam ja pročitao viče kojekakve senzore za očitavanja raznoraznih parametara tokom testiranja.

Citat:Generally speaking, as observed on other types, the “trailing cone” is usually a nylon cable with a stabilizing cone deployed in flight, generally 1 to 1.5 times the wing span length, or about 50 metres, behind the aircraft to measure the ambient atmospheric pressure (static pressure) precisely, in the “free-stream air-flow” outside the disrupted air-flow generated by the aircraft – a key parameter for the pilots.

Sightings of the B-21 Raider stealth bomber are becoming more frequent on the U.S. West Coast, as testing of the 6th generation bomber continues.
On Oct. 31, 2024, aviation photographer Jarod Hamilton took some stunning shots of a Northrop Grumman B-21 Raider that was involved in a test flight inside the R-2508 Complex, located in Southern California.

Procena od 19,1 milijardu $ za pocetnu proizvodnju prvih 5 lotova je pala na 13,8 milijardi $ sto je smanjenje od 5,3 milijarde. 2010. je cilj bio cena od maksimalno 550 miliona $ po avionu ( uz dodatu inflaciju to je danas 730 miliona $ ) a onda da padne na procenjenih 510 miliona $ iz 2015. godine sto je 678 miliona u 2024.

Citat:In 2010, then-Defense Secretary Robert Gates set the maximum price for each B-21 at $550 million. Following the contract award to Northrop in 2015, the service lowered the target to $511 million, citing the defense prime contractor’s winning proposal.

The Defense Department’s deflator formula adjusts that target average procurement unit cost for each aircraft in 2024 dollars to $730 million.

The Air Force refuses to release the number of aircraft it plans to buy in the LRIP process, citing classification rules. At the time of contract award in 2015, however, the service was more open, saying that 21 aircraft would be acquired over that five-year period.

If that number has not changed, then the Air Force now plans to spend an inflation-adjusted amount of $668 million for the first 21 Raiders instead of $733 million. And the $668 million figure likely includes additional costs such as an initial spares package.

Komadant strateske komande se zalaze za bar 145 B-21 uz 75 modernizovanih B-52. Takodje trazi veci broj novih nuklearnih raketa od planiranih 1087 LRSO.

Citat:This is not the first time Cotton has indicated he would like more Raiders. Last year, he told lawmakers that he would “love” to have more than 100 of the bombers, but he did not offer the 145 figure he presented now.

“That gives us 220 bombers when the BUFFs (B-52s) are included,” Cotton said at McAleese. Cotton also said he’s “really happy with the work Northrop Grumman is doing” with development and testing of the B-21.

He also praised Raytheon for its “amazing” work on the LRSO, the new nuclear missile the Air Force is working on to succeed the AGM-86B Air-Launched Cruise Missile. Like the B-21, though, he suggested the program needs to grow.

“Again, we have to question now, what are we looking for, as far as capacity [and] sufficiency, there,” Cotton said, due to the evolving security situation, without specifying how many additional LRSOs he thinks should be acquired. He’s ready to “move out” with that program, he said.

The Air Force plans to buy 1,087 LRSOs, 67 of which would be used for development and test. That figure was set in the early 2010s and was largely based on the nuclear capabilities of Russia, before China embarked on an aggressive campaign of building strategic weapons and developing new hypersonic missiles. The LRSO is highly classified and is set to enter operational service in the late 2020s.
