Most recently, the B-52 showed its diplomatic chops when two BUFFs were dispatched to violate China’s newly declared Air Defense Zone. The BUFF was perfect for this mission; the Chinese could not pretend not to notice two enormous bombers travelling at slow speed through the ADIZ.

742 B-52s were delivered between 1954 and 1963. Seventy-eight remain in service, having undergone multiple upgrades over the decades that promise to extend their lives into the 2030s, or potentially beyond. In a family of short-lived airframes, the B-52 has demonstrated remarkable endurance and longevity.

Conclusion

Over the last century, nations have invested tremendous resources in bomber aircraft. More often than not, this investment has failed to bear strategic fruit. The very best aircraft have been those that could not only conduct their primary mission effectively, but that were also sufficiently flexible to perform other tasks that might be asked of them. Current air forces have, with some exceptions, effectively done away with the distinctions between fighters and bombers, instead relying on multi-role fighter-bombers for both missions. The last big, manned bomber may be the American LRS-B, assuming that project ever gets off the ground.
