And this versatility has been the real story of the B-52. The BUFF was first committed to conventional strike missions in service of Operation Arc Light during the Vietnam War. In Operation Linebacker II, the vulnerability of the B-52 to air defenses was made manifest when nine Stratofortresses were lost in the first days of the campaign. But the B-52 persisted. In the Gulf War, B-52s carried out saturation bombing campaigns against the forward positions of the Iraqi Army, softening and demoralizing the Iraqis for the eventual ground campaign. In the War on Terror, the B-52 has acted in a close air support role, delivering precision-guided ordnance against small concentrations of Iraqi and Taliban insurgents.

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.
