Honeywell Wins $249M Army Contract for CH-47 Chinook Engine MRO

Honeywell Aerospace has secured a $249 million contract from the U.S. Army to provide repair and overhaul services for the T55-GA-714A turboshaft engines powering the Boeing CH-47 Chinook helicopter fleet.

The three-year Indefinite Delivery, Indefinite Quantity (IDIQ) agreement, announced in a June 2026 press release, ensures a continuous supply of serviceable powerplants for the military through May 2029. The U.S. Army Contracting Command at Redstone Arsenal officially awarded the Contracts on May 21, 2026.

Commercial processes drive military maintenance efficiency

Maintenance, repair, and overhaul (MRO) work will take place at Honeywell’s aerospace headquarters in Phoenix, Arizona. The company is applying commercial aviation maintenance methodologies to its military engine overhaul program to increase throughput and reduce turnaround times.

Brian Laughton, Senior Director and Site Leader of the Phoenix repair facility, stated that the T55 line utilizes the same processes applied to the company’s Federal Aviation Administration (FAA) certified lines for business jet turbofan engines.

Capitalizing on these proven commercial processes has enabled us to double our capacity in the facility and reduce cycle time to ensure we are meeting delivery commitments to our customers.

Legacy and evolution of the T55 engine program

The T55 engine originally entered service in 1961. Over the past six decades, Honeywell has manufactured more than 6,000 T55 engines, accumulating approximately 12 million flight hours across the CH-47 and MH-47 variants.

The powerplant has undergone significant upgrades since its introduction. The current T55-GA-714A variant produces approximately 5,000 shaft horsepower, representing a threefold increase in output compared to the original 1960s design. The engine currently supports the U.S. Army and more than 15 international military operators.

Dave Marinick, President of Engines & Power Systems at Honeywell Aerospace, noted the company’s long-term commitment to the platform, stating that Honeywell looks forward to continuing its support for the engine program for decades to come.

AirPro News analysis

We observe that cross-pollinating commercial FAA-certified maintenance practices into military depot-level work is becoming a critical strategy for aerospace Manufacturers. By doubling facility capacity without necessarily expanding the physical footprint, Honeywell is addressing the persistent supply chain and turnaround time bottlenecks that have challenged military readiness in recent years. The $249 million valuation for a three-year period highlights the intense operational tempo and heavy utilization of the global Chinook fleet.
