Over its sixty-year lifetime, the B-52’s avionics, flight hardware, and weapons systems have been upgraded. In 2006, the fleet received a “mid-life” upgrade to its avionics, adding modern processors and navigation systems. In 2014, the Air Force gave the BUFFS their first new communications system since the 1960s, including full-color LCDs to replace the old cathode ray tube screens. <span>On the weapons front, the airplanes are due to receive weapons-bay upgrades, enabling them to hold more smart bombs, and radar enhancements, potentially including the Active Electronically Scanned Array Systems technology.
