Bell Textron has announced the completion of the first two AH-1Z Viper and UH-1Y Venom helicopters modernized under SPINE(Structural and Power Improvements for NextGen Effects) program, a United States Marine Corps initiative that aims to develop the H-1 fleet for modern combat scenarios.
The completed aircraft left the Amarillo Assembly Center in Texas and were transferred to Naval Air Station Patuxent Riverwhere they undergo a new phase of flight tests. This phase will be crucial to validate the final configuration of the modernization package to be implemented on the rest of the fleet.
SPINEprogramme, formerly known as SIEPU (Structural Improvement and Electrical Power Upgrade), has been reworked to reflect a broader approach. The focus is now on securing greater structural capacity, increased electrical power and a robust digital platform for the integration of next-generation technology.
These improvements will enable the H-1 helicopters to operate with new weapon systems, advanced sensors and expanded digital capabilities, enhancing their strike power and survivability in increasingly complex combat environments.
According to Scott Sims, director of the H-1 program at Bell, the delivery of these first units marks a strategic milestone. He emphasized that the updates are designed to keep the helicopters at the front line of military operations for many years to come, with a focus on crew safety and operational efficiency.
The modernization process involved several of the company’s units, including the Drives System Center (DSC) and the Repair and Overhaul Center (ROC), before the final modifications were completed over a 19-month period in Amarillo. The project also involved close collaboration between the US government, industry and strategic partners.
For program manager Danielle Markham, SPINE represents an important step in the development of the H-1 platform, ensuring that the aircraft remains competitive and fully integrated into modern joint forces.
With the completion of this initial phase, the program is expected to enter a continuous modernization cycle over the next decade, which will strengthen the role of the AH-1Z and UH-1Y helicopters as strategic assets in United States Marine Corps operations.
