Snakes and Rotors: The H-1 Helicopter Program
April 9/17: Bell Helicopters is scheduled to deliver the first three of 12 AH-1Zs to Pakistan this summer, with the remainder to be delivered next year after being handed over to the US government. Approval for the deal was granted by Washington last April. The sale comes as the company expects the signing of a second export order for the H-1 series UH-1Y Venom utility and AH-1Z Viper attack helicopters in the coming months.
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.
