US F-35Bs will begin flying off United Kingdom aircraft carriers in 2021, British Defense Minister Michael Fallon announced Thursday as a way to “return the favor.” United Kingdom Royal Air Force and Royal Navy pilots have been able to test fly F-35s off US aircraft carriers as part of the country’s “regeneration of UK carrier strike capability,” Fallon said during a joint appearance with US Defense Secretary Ash Carter in London. Beginning in 2021, US F-35Bs will start flying from Queen Elizabeth carriers. UK pilots have been operating on the USS America, using a 10-member team assigned to the F-35 Pax River Integrated Test Force. This team conducted a 23-day embarkation, according to a Navy release.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
