Original vintage Cold War 1969 Honeywell "All For One Man" advertisement for the defense contractor's AN/AYK-5 (ALERT) military computer - "A fully-militarized computer that helps him find and classify hostile forces...fast!"
Dimensions: Approx. 16.50 inches wide by 11 inches high - this is a two-page advert.
"The ALERT Computer accepts, analyses, filters and correlates thousands of inputs per second from reconnaissance sensors to identify hostile targets. It computes the location of the target and generates pictorial displays relative to other combat elements. Its fast, reliable and precise operation permits a man to dispatch and direct strike forces against key targets."
The AN/AYK-5 ALERT Computer
The AN/AYK-5 ALERT (Airborne Low-cost Electronic Rouser / and Tailored or similar military nomenclature, widely known as the ALERT computer) is a vintage, fully militarized airborne digital computer system manufactured by Honeywell in the late 1960s.
Developed by Honeywell Aerospace during the mid-to-late 1960s, it utilized advanced state-of-the-art integrated circuits and printed microcircuitry designed to withstand rugged military flight environments.
Aside from military applications, it was also famously deployed as a supplemental boost-and-entry guidance and navigation computer system on experimental high-speed research aircraft, including the NASA X-15-3 rocket plane.
Honeywell International, and Honeywell Aerospace
Honeywell International Inc. is an American Fortune 500 publicly traded, multinational conglomerate corporation headquartered in Charlotte, North Carolina, and primarily operates in three areas of business: building automation, industrial automation, and energy and sustainability solutions (ESS). Honeywell also operates Sandia National Laboratories under contract with the U.S. Department of Energy. In 2025, the corporation had a global workforce of approximately 101,000 employees.
Within the Honeywell enterprise umbrella lies Honeywell Aerospace, a core division of the Honeywell International conglomerate. Honeywell Aerospace Technologies is responsible for over thirty percent of Honeywell's total revenue with half from commercial contracts and half from defense contracts, and the division generates $15 billion USD in annual sales.
The company experienced a foundational manufacturing boom during World War II, when it equipped Allied bomber aircraft with specialized avionics and invented the modern electronic autopilot. After the war, it successfully shifted focus toward commercial aviation and peacetime applications. Today, Honeywell Aerospace produces advanced space exploration equipment, micro-electronic systems, turbine engines, braking systems, synthetic vision, runway safety infrastructure, and flight deck avionics.
A Honeywell APU was instrumental in maintaining backup systems during the emergency river landing of US Airways Flight 1549, and a ruggedized Honeywell flight data recorder survived underwater for nearly two years to provide critical diagnostics for the investigation into Air France Flight 447. The company has historically contributed to nearly 90 percent of United States space missions, including design consulting for technical props in 2001: A Space Odyssey.
In 2010, President Barack Obama awarded longtime Honeywell safety engineer Don Bateman the National Medal of Technology for his development of ground proximity warning systems which radically reduced controlled flight into terrain accidents. The company holds an extensive patent portfolio detailing flight windshield engineering, aerospace turbochargers, and satellite communications hardware, following the resolution of a notable historical 11-year patent dispute regarding ring laser gyroscope technology.
In 2025, Honeywell announced it would split into three companies: Honeywell Technologies, Honeywell Aerospace, and Solstice Advanced Materials. It has been estimated that the aerospace and automation businesses could be worth as much as $104 billion and $94 billion, respectively, after the split.
