Honeywell's corporate line began in heating and automatic-control technology, with Honeywell's own history tracing the Honeywell Heating Specialty Co. to 1906 and the 1927 combination of Minneapolis Heat Regulator Company and Honeywell Heating Specialty Co. into Minneapolis-Honeywell Regulator Co. The same source records a later expansion into aerospace and high-technology work before AlliedSignal acquired Honeywell in 1999 and kept the Honeywell name for the combined company.
Defense-relevant Honeywell Incorporated work is clearest in older U.S. naval and ordnance records. The Naval Submarine League history of U.S. torpedoes identifies the Honeywell-Garrett Ex-50 as the selected design that became the MK 50 lightweight torpedo, while the catalog's Mk 20 Rockeye record uses a published source that identifies MK-20 Rockeye production by Honeywell Incorporated. A separate Alliant Techsystems SEC filing explains how Honeywell spun off its Defense and Marine Systems Business, Test Instruments Division, and Signal Analysis Center in 1990, placing part of the legacy defense-industrial base into Alliant.

This profile is limited to the historical Honeywell Incorporated attribution used by older weapon sources. The broader current Honeywell corporate page is maintained separately, so aliases already owned by that profile are intentionally not repeated here.
