Snakes and Rotors: The H-1 Helicopter Program
October 18/16: Bell Helicopters is keen to sell its AH-1Z attack helicopter as a solution to Japan’s AH-X program . As part of preparations the company has teamed with engineers from Fuji Heavy Industries on modification work to the helicopter aimed at improving transmission performance. If selected, between 60-70 of the Bell 412EPI -based helicopters would be produced locally in Fuji with the first slated to deliver in 2022. Civilian variants would also be produced in Fuji in an effort to help the production line attain scale.
The US Marines’ helicopter force is aging at all levels, from banana-shaped CH-46 Sea Knight transports that are far older than their pilots, to the 1980s-era UH-1N Hueys and AH-1W Cobra attack helicopters that make up the Corps’ helicopter assault force. While the tilt-rotor V-22 Osprey program has staggered along for almost 2 decades under accidents, technical delays, and cost issues, replacement of the USMC’s backbone helicopter assets has languished. Given the high-demand scenarios inherent in the current war, other efforts are clearly required.
Enter the H-1 program, the USMC’s plan to remanufacture older helicopters into new and improved UH-1Y utility and AH-1Z attack helicopters. The new versions would discard the signature 2-bladed rotors for modern 4-bladed improvements, redo the aircraft’s electronics, and add improved engines and weapons to offer a new level of performance. It seemed simple, but hasn’t quite worked out that way. The H-1 program has encountered its share of delays and issues, but the program survived its review, and continued on into production and deployment.
DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article covers the H-1 helicopter programs’ rationales and changes, the upgrades involved in each model, program developments and annual budgets, the full timeline of contracts and key program developments, and related research sources.
