Bell TextroBell Textron Inc. announced the completion of the first AH-1Z and UH-1Y aircraft that have undergone comprehensive upgrades to their structural components and power transmission systems. These upgrades were part of the U.S. Marine Corps’ SPINE program.
Bell, a Textron Inc. company, has reached a significant milestone in the SPINE (Structural and Power Improvements for NextGen Effects) program. This program focuses on enhancing survivability and lethality throughout the operational life of the H-1 helicopter fleet. Previously, it was known as SIEPU (Structural Improvement and Electrical Power Upgrade). The modernization effort has been renamed to emphasize the platform’s future capabilities and technological transformation and is now referred to as the SPINE Program.
Testing Process and Operational Objectives
The first two aircraft completed processing at the Amarillo Assembly Center. They have been delivered to Naval Air Station Patuxent River to continue flight testing. These tests will define the final SPINE configuration. Additional aircraft will be modified in Amarillo. They will be delivered to the U.S. Marine Corps under future contract work in line with the requirements of the SPINE Program.
The SPINE program is part of a comprehensive modernization plan. This plan enables the H-1 fleet to employ upgraded weapons systems and other future capabilities. The improvements aim to enhance modern combat effectiveness, increase lethality, and improve platform survivability.
Scott Sims, Bell H-1 Program Director, emphasized the significance of completing the first two aircraft. He stated that these upgrades will ensure H-1 platforms remain among the most capable assets on the front lines of modern missions. Additionally, Sims highlighted that crew safety and aircraft effectiveness remain top priorities. He noted that the aircraft will continue to fulfill their intended missions for many years with the enhanced reliability brought by the SPINE Program.
Technical Modifications and Future Outlook
Modification work on the aircraft began at Bell’s Drive Systems Center (DSC) and Repair and Overhaul Center (ROC). The process was completed over the past 19 months. Electrical and structural changes were carried out at the Amarillo Assembly Center, all as a part of the ongoing SPINE Program.
Bell Program Manager Danielle Markham stated that the SPINE program provides the platform with the necessary structural durability, electrical capacity, and digital infrastructure. Therefore, the aircraft will be capable of operating effectively in all environments. They will act as fully integrated elements of modern joint forces.
The successful completion of the initial modification work at the Amarillo Assembly Center paves the way for future growth. This supports Bell’s objective to continue upgrading the Marine Corps’ H-1 fleet over the next decade. Moreover, the achievement also reflects years of collaboration between the U.S. government, Bell, and industry partners, all contributing to the SPINE Program’s success.
