USA Northrop Grumman skal bygge USAs neste bombefly - B-21 Raider

Nå vet man aldri om siste ord er sagt, og langt mindre hvordan flyet kommer til og se ut, men Northrop Grumman er tildelt oppgaven med og designe og bygge USAs neste generasjons langdistanse stealth bombefly som skal avløse B-52 og B-1

Quote:
Northrop’s victory in the $80 billion Long Range Strike Bomber (LRS-B) competition has been described as “stunning upset” against the cashed-up team of Boeing and Lockheed Martin, and secures the B-2 creator’s place as a top-tier military aircraft manufacturer for decades to come.

The development contract includes options for the first 21 aircraft of what could become an at least 100-aircraft production run. Pentagon estimators place the cost of development at $23.5 billion in fiscal year 2016 dollars, and the aircraft itself valued at $564 million per copy.

Interessant at kontrakten gikk til Northrop Grumman som vel må betraktes som en underdog i dette selskapet. Sterkt å konkurrere ut konstellasjonen Boeing/Locckheed Martin. Men det var vel Northrop som også bygde B2?

Northrop har jo allerede konstruert B-2, og var med i konkurransen som endte med F-117, så de er nok ikke helt tapt bak en vogn Er dog enig i at de er som underdog å betrakte når man sammenligner med Boeing og LM i dag.

Jeg vil tro at deres teknologi og ingeniør kapasitet er vesentlige faktorer for tildeling av denne kontrakten.
Boeing konsernet har betydelige ressurser opptatt med pågående prosjekter i lang tid fremover.
Ikke mye tilgjengelig ingeniør og prosjekt management kapasitet der i overskuelig fremtid.
Det slike faktorer som tillegges vekt når nye prosjekter skal lanseres i tillegg til den historiske kompetanse/produksjon.

Fant en interessant illustrasjon av LRS-B i en avis her forleden. Denne viser at den nye bomberen er ganske mye mindre enn B-2.

Da har de hatt en slags rollout av flyet

Northrop Grumman and the U.S. Air Force have revealed the B-21 Raider stealthy long-range bomber to the public for the first time. The December 2 ceremony was held under darkening skies at the manufacturer’s facility at Palmdale Airport in California and was attended by Northrop Grumman personnel and senior military and government officials, including defense secretary Lloyd Austin.

den har hatt første flyvvning idag. finnes videoer på youtube btw. https://breakingdefense.com/2023/11/...-first-flight/

Quote:
“The B-21 Raider is in flight testing,” Air Force spokesperson Ann Stefanek told Breaking Defense in a statement today. “Flight testing is a critical step in the test campaign managed by the Air Force Test Center and 412th Test Wing’s B-21 Combined Test Force to provide survivable, long-range, penetrating strike capabilities to deter aggression and strategic attacks against the United States, allies, and partners.”
