I see the new B-21 Raider took it's first flight last Friday, I think.
I read in either Combat Aircraft Journal or Air Forces Monthly, that the USAF Bomber Component will consist of two types, the B-52 and the B-21.
I know that a few B-1s have been retired and the B-2 won't have a role to fill.
The interesting thing is the BUFF is being modernized, new cockpit, engines, self protection measures etc.
The USAF have said that with the modernization program, the B-52 will still be in service until the 2040s maybe into the 2050s.
Not bad for a 1950s design...sometimes low tech is better than hi-tech...
