FoundedN/A

Hamilton Sundstrand was a global aerospace and industrial company formed in 1999 through the merger of United Technologies' Hamilton Standard division and the Sundstrand Corporation. Both parent companies had rich, independent histories in aviation and industrial products. As a subsidiary of United Technologies Corporation (UTC), Hamilton Sundstrand designed, manufactured, and serviced a wide array of products. These included critical aircraft systems such as electric power generation and distribution, engine controls, environmental control systems, propellers, and emergency power systems. The company also had significant involvement in space systems, notably providing life support equipment and space suits for NASA. In 2012, United Technologies acquired Goodrich Corporation and subsequently merged it with Hamilton Sundstrand to form UTC Aerospace Systems. This entity was later combined with Rockwell Collins in 2018, creating Collins Aerospace. Collins Aerospace is now a major business unit of RTX Corporation. The pioneering spirit and technological advancements of Hamilton Sundstrand continue to be integral to the products and innovations offered by Collins Aerospace today.
