UTC Aerospace Systems Bradley Airport, Connecticut

UTC Aerospace Systems has a major manufacturing plant located near the main terminal for Bradley Field. The plant was operated for years by Hamilton Standard (later known as Hamilton Sundstrand), making parts for military and civilian aircraft, especially specialty pumps, compressors, propellers, power systems, thermal controls, and life support systems, which included space suits for NASA. This was the company’s headquarters as well, though now, through mergers and consolidations is part of UTC Aerospace, which itself is a subsidiary of United Technologies, a major industrial conglomerate based in Farmington, Connecticut, with plants throughout the state.
