The Army has awarded Honeywell [HON] a $476 million deal for T55 engines used to power its CH-47 Chinook heavy-lift helicopters. 

Work on the deal, announced by the Pentagon on Monday evening, is expected to be completed by the end 2023.

The award also includes engine electronic control units and installation kits.

Last June, Honeywell announced the company has reached an agreement with the Army to demonstrate the latest version of its T55 engine, the upgraded T55-GA-714C engine, on a CH-47 by 2023 (Defense Daily, June 4 2020). 

In September, the Army conducted its first flight of a CH-47 with GE Aviation’s [GE] T408 engines, the same one used on the Marine Corps’ CH-53K helicopter (Defense Daily, Sept. 23). 

The demonstration followed a five-year cooperative research effort with Boeing [BA] and GE to assess the potential for the T408 to expand the mission capabilities for the Chinook heavy-lift aircraft.
