It’s been an ongoing joke that the venerable B-52 bomber fleet are older than the crews that fly them. With a recent announcement, the US Air Force has ensured that the joke will change — by the time they retire, the planes will be older than the parents of their crews:
Without any fanfare, the U.S. Air Force recently announced that it would spend $11.9 billion to keep its remaining B-52 bombers in service until they are all retired by 2040. At that point, the last ones will have served over 70 years. The new “sustainment program” will cost over $150 million per aircraft, which is about twice what they cost to build (accounting for inflation).
The reason for this investment in half century old aircraft has a lot to do with the fact that the B-52 is very capable, reliable, and cheap to operate. This is especially true compared to the aircraft built to replace it (the B-1B). The U.S. Air Force has been having a hard time keeping its 67 B-1B bombers ready for action. Two years ago, the availability rate (aircraft you can send into action) was about 51 percent. Seven years ago it was 56 percent. Progress is being made, but the B-52 is still more reliable. The B-1Bs are used to drop smart bombs in Iraq and Afghanistan. They are particularly popular in Afghanistan, because you can put one in the air, and it can cover the entire country. While the B-1B is twice as expensive to operate (per hour in the air) than the B-52, the B-1B can more quickly move to a new target over Afghanistan.
B-52s are not only cheaper to maintain, they have a higher availability rate (65 percent.) As a result, the air force wants to keep 76 B-52s in service (despite a Congressional mandate to reduce that number to 56.) With the development of GPS guided bombs (JDAM), heavy bombers have become the most cost-effective way to deliver support to ground forces. The B-52 is the cheapest American heavy bomber to operate, and the oldest.
