In February 2008, a B-2 stealth bomber crashed shortly after takeoff from the Andersen Air Force base in Guam. In April, a B-1B strategic bomber exploded after landing at the Al-Udeid Air Base in the United Arab Emirates.

Even though the immediate cause for the crash of B-52 has not been named yet, it is likely to have something to do with its venerable age. These planes went into mass production in 1953-1963, and B-52H planes entered operational service in 1960-1963, making their average age about 47 years.

The B-52 has been repeatedly modernized, but the modernization that improved the plane's equipment and weapons could not give new life to the worn-out superstructure, while capital repairs can prolong the life of the plane but not make it immortal. At the same time, however, the B-52 is not on the way out as a combat vehicle because there is no adequate substitute available. Indeed, it is likely to stay in service up to 2040's.

This seems absurd, especially when the U.S. has developed several types of strategic bombers to replace the B-52. Its first attempt was the XB-70 Valkyrie, but this supersonic bomber turned out to be too expensive and the program was cancelled.

The second was the B-1A bomber developed in 1960-1970's. However, by the late 70's this plane, which was equipped only with bombs, seemed to be obsolete. Instead, the U.S. started developing the B-1B. But even the modernized version could not carry ALCM long-range standoff attack missiles, but only shorter-range SRAM missiles.

As a result, the B-52H equipped with long-range missiles remained the main strategic workhorse of the U.S. Air Force. Moreover, in accordance with the Soviet-American agreements on nuclear weapon reduction, the B-1B lost its SRAM missiles, which were eliminated, and since then has been carrying only bombs (although the U.S. is planning to bring into service the new JASSM cruise missile).

The last strategic bomber to be developed was the B-2, which went into production in the beginning of the 1990's. But this replacement for the B-52 turned out to be too expensive even for the American budget - one aircraft cost about $1.5 bn. As a result, the U.S. only produced 20 B-2s and kept the B-52 in service.

At this moment there is no alternative to the B-52. It is the only aircraft that can fulfill all the tasks of strategic aviation, from carpet-bombing to strikes on well-protected targets using long-range high-accuracy missiles.

The development of a new aircraft that would replace all thee planes is at the pre-design stage. Taking into account the terms and the cost of modern planes, it is possible that the B-52, like its Russian counterpart the Tu-95, will celebrate the 100th anniversary of its operational service. We don't have to wait long - only until 2055.
