That is true, and they’re planned to stay in service (with new engines and radars) until at least 2050! They fly a lot less than a commercial airliner though, with wing surfaces limited to ~30,000 hours.

Whereas the 767 is rated up to 50,000 cycles. In 2010, the feet leader had 101,000 hours and 31,000 cycles. (https://www.elal.com/en/ELALTech/Documents/Press_Releases/767.pdf https://www.elal.com/en/ELALTech/Documents/Press_Releases/76...)
- dsfyu404ed 8y agoIt's an apples to oranges comparison. The types of air-frames are totally different. A B52 has a wing that flops all over the place the entire fuselage is not pressurized like on a commercial jet. Also commercial aviation is a lot less hard on equipment than military service because they optimize for comfort and cost whereas the military is going to doing combat readiness stuff regularly and that involves much more stress on the air-frames.
- moftz 8y agoThe military does run their stuff pretty hard but at the same time a commercial airliner pretty much runs 24/7 because every minute it's not in the air is a waste of money. Military stuff always has to be ready to go but that doesn't mean it's always actually doing something.
