Honeywell Aerospace
HONHoneywell Aerospace is a reportable business SEGMENT of Honeywell International (NYSE: HON) — not a separately-filing subsidiary. It accounts for ~37% of total Honeywell revenue (~$13.6B of ~$36.7B in FY2023), with three product lines: Commercial Aviation (avionics, propulsion, mechanical), Defense & Space (~$5B sub-line — avionics, propulsion, mission systems for primes), and Honeywell Connected Aircraft. The published autonomy framework is "See / Think / Act / Communicate" — a four-pillar architecture covering perception, mission planning, vehicle control, and resilient comms. Honeywell Aerospace is a Tier-2 systems / avionics supplier to LMT/RTX/NOC/GD/BA, not a peer defense prime.
From the source
Honeywell Aerospace Technologies is a manufacturer of aircraft engines and avionics, as well as a producer of auxiliary power units (APUs) and other aviation products. Headquartered in Phoenix, Arizona, it is a division of the Honeywell International conglomerate. It generates approximately $15 billion in annual revenue from a 50/50 mix of commercial and defense contracts. The company experienced a boom during World War II, when it equipped bomber planes with avionics and invented the autopilot. After the war, it transitioned to a heavier focus on peacetime applications. Today, Honeywell produces space equipment, turbine engines, auxiliary power units, brakes, wheels, synthetic vision, runway safety systems, and other avionics. A Honeywell APU was used in the notable emergency landing of US Airways Flight 1549, and a Honeywell blackbox survived under sea for years, thus exceeding by far its specified limits to reveal the details of the crash of Air France Flight 447. The company was also involved in the making of 2001: A Space Odyssey and in 90 percent of U.S. space missions. It is involved in the U.S. NextGen program and Europe's SESAR program for advancing avionics. President Barack Obama awarded longtime Honeywell engineer Don Bateman the National Medal of Technology in 2010 for his contributions to air flight safety technology. The company owns dozens of patents related to NextGen technology, aircraft windshields, turbochargers, and more. It was also involved in an 11-year-long patent dispute regarding ring laser gyroscope technology.
