Honeywell International and Pratt & Whitney have received requirements contracts totaling $27 million for engineering, research, and development of secondary power systems for multiple platforms of the U.S. Air Force. The twin contracts, announced by the U.S. Department of Defense, will cover much of the Air Force’s existing air fleet.
Maintaining and upgrading the secondary power systems is vital to keeping older legacy aircraft viable toward the end of their service lives. Secondary power systems serve two main purposes: starting the aircraft’s engines with the aid of a start cart, and then, once the engine’s operation is self-sustaining, transmitting power to the aircraft’s other systems.
Honeywell and Pratt & Whitney have been tasked with the development of improved safety, reliability, and lower operating costs on the secondary powers systems of F-15, F-14, and A-10 fighters, B-1 and B-2 bombers, C-130 and C-5 cargo planes, and KC-135 tankers. The two companies will conduct the work at East Hartford, Connecticut, and Phoenix, Arizona, with completion of the project expected by July 2025.
