A B-52 Stratofortress has been equipped with a new radar system, with some outlets reporting that the modified aircraft has arrived at a US air force base for testing. The upgrade is part of efforts to enhance the bomber's capabilities, although readiness issues and a recent crash may be creating challenges for the testing process. The new radar system is one of several developments underway for the B-52, which is also set to be used in conjunction with new missiles and other emerging technologies.
