The USAF currently plans to retire the B-1B in the 2020-25 time frame last I heard, I don't know when they plan to retire the B-2, but the B-52
isn't scheduled for retirement until 2040!
My guess is that they will retire the B-2 at some time before the B-52. There's no hard data how well it's composite components will hold up over
the years. But even if it is retired in 2040, it will still be a 50+ year old aircraft.
You can put down hard money that before they retire the BUFF, it will be a vastly different aircraft then the ones flying today. It will probably
armed with some form of airborne laser for self defense. The underwing pylons may carry some form of UCAV escort/strike fighter. It will also
probably have some sort of passive radar absorbtion material to mask or change its signature to look like a commercial airliner. It will be
re-engined to more modern turbofan engines probably from eight engines to four.
For those you who haven't worked with the BUFF, it is the most heavily modified aircraft ever built. When I last worked with them in '96, they had
had over 13,000 different modifications since the original accepted aircraft design. When the last E/R/F/B-52XX goes to the boneyard, it will be the
last of the Cold Warriors, long outflying most of its pilots.
This is my last post on this subject, you BUFF detractors!
