Boeing has so far delivered at least four serial CH-47F Block II helicopters. All were assigned to the 101st Airborne Division, where they underwent operational testing with positive results, paving the way for a long-term agreement.
In addition to limited U.S. Army orders for Block I to Block II upgrades, Boeing has secured export customers including the United Kingdom, Germany and Japan. Deliveries of MH-47G Block II variants for U.S. Special Operations Forces are also continuing.
According to the plans of the U.S. Department of War, the existing fleet of around 465 CH-47F Chinook Block I helicopters will eventually be upgraded to the Block II configuration. The modernised aircraft also remains available for export.
