The B-52 Stratofortress is a plane that really needs no introduction. It’s big, it’s loud, and it’s smoky. It’s also incredibly old. So old that the last airframes to roll off the production line took to the skies in the early 1960s, right in the thick of the Cold War. Despite its age, the plane commonly known as “The BUFF” remains a dependable and capable long-range bomber for the U.S. Air Force. As the B-52H enters its seventh decade of service, there are no plans to retire the type. In fact, the US Air Force has laid out a host of upgrades that will see a jet designed with slide rules become a networked, high-tech, multi-role, long-range platform of the future…and potentially serving for over a century. This deeply revamped Stratofortress that will serve alongside the B-21 Raider will be known as the B-52J. Here are all the upgrades that will make its modernization makeover complete.
