Enhanced Chinooks

The U.S. Army is continuing to modernize its heavy-lift helicopter fleet with an order for two more Boeing CH-47F Block II Chinooks and long lead funding for additional aircraft.

«Modernizing the Chinook for our Army customer is a priority», said Ken Eland, Boeing vice president and H-47 program manager. «CH-47F Block II improves readiness, limits future sustainment costs and provides commonality across the fleet. We’re dedicated to making CH-47F Block II the best option for the Army’s heavy lift mission, now and well into the future». The CH-47F Block II Chinook is powered by cutting-edge technologies – including redesigned fuel tanks, a strengthened fuselage and an enhanced drivetrain.

Last year, the Army awarded Boeing a $136 million contract for the first four CH-47F Block II aircraft, which began production in April 2022. The Lot 2 order valued at $63 million brings the total number of aircraft under contract to six. The separate Lot 3 advance procurement contract is valued at $29 million.

Boeing’s H-47 Chinook Block II expands upon 60 years of partnership with the U.S. Army. During that time, Boeing has delivered over 1,000 Chinooks to the U.S. Army, continuously modernizing the helicopter to meet evolving needs. The U.S. Army and 19 allied countries around the globe rely on the Chinook for its multi-mission capabilities including equipment and troop transport, humanitarian assistance and disaster relief.

The Army exercised options for four contracted CH-47F Block II Chinooks with the aircraft scheduled for delivery beginning 2023. Separately, the Army awarded Boeing a $29 million advanced procurement contract for the second production lot of CH-47F Block II aircraft.

The Block II Chinook features multiple upgrades aimed at providing additional lift capability and increasing commonality between U.S. and allied fleets, thus reducing maintenance costs.

«This is a big step in Chinook modernization, supporting the Army’s future multi-domain vision», said Andy Builta, vice president of Cargo & Utility Helicopters and H-47 program manager. «The Block II technologies will drive commonality across the fleet and enable our soldiers to return home safely for decades».

As a leading global aerospace company, Boeing develops, manufactures and services commercial airplanes, defense products and space systems for customers in more than 150 countries. As a top U.S. exporter, the company leverages the talents of a global supplier base to advance economic opportunity, sustainability and community impact. Boeing’s diverse team is committed to innovating for the future and living the company’s core values of safety, quality and integrity.

Add Muscle to Chinook

Boeing will build and test three U.S. Army CH-47F Block II Chinook helicopters as part of a modernization effort that will likely bring another two decades of work to the company’s Philadelphia site.

A recent $276 million Army contract will fund those helicopters, which will validate technology advancements that will increase the iconic helicopter’s lifting power.

«The Army’s only heavy-lift helicopter exists to deliver decisive combat power for our ground commanders», said Colonel Greg Fortier, U.S. Army project manager for Cargo Helicopters. «The Cargo family is anxious to build upon Col. Rob Barrie’s efforts to establish this critical program and deliver an adaptive air vehicle. Increasing payload capacity today enhances battlefield agility and prepares the Chinook for even greater performance gains in the future».

An improved drivetrain will transfer greater power from the engines to the all-new, swept-tip Advanced Chinook Rotor Blades, which have been engineered to lift 1,500 additional pounds on their own. The current configuration of six fuel tanks – three on each side – will become two, allowing the aircraft to carry more fuel and shed weight. Additionally, the fuselage’s structure will be strengthened in critical areas to allow the aircraft to carry additional payload.

«This latest upgrade for the Chinook fleet is a tribute to the robustness of its original design and exemplifies its 55-year legacy of technological advancements», said Chuck Dabundo, vice president, Cargo Helicopters and program manager, H-47. «The fact that the U.S. Army continues to use and value this platform and they are intending to continue to upgrade it to keep it flying for decades to come is a testament of the capabilities the Chinook team continues to bring».

Boeing will begin building the test aircraft next year. The test program begins in 2019 and first delivery of the Block II Chinook is expected in 2023. Eventually, the Army will upgrade more than 500 Chinooks to Block II configuration.
