The U.S. Air Force equips its 76 B-52H Stratofortress bombers with B-52 electromechanical star trackers. These 1950s analog computers measure star angles to correct inertial drift. Boeing maintains them under contracts that generated $25.6 billion in 2023 defense revenue, per Boeing's 2023 Annual Report.
Star trackers lock onto stars like Vega or Sirius. Gears and cams process angles mechanically. This setup avoids software flaws. Technicians at Barksdale Air Force Base service units quarterly for 100% readiness, according to the U.S. Air Force B-52H fact sheet.
IBM engineers built early astro-inertial systems in the Cold War. Passive optics and mechanical cams deliver reliability no digital match equals.
