SCALABLE CONTROL INTERFACE (SCI)

The Scalable Control Interface (SCI) program is a new initiative introduced in the Army's Fiscal Year 2026 Aircraft Procurement budget, specifically under the Modification of Aircraft subactivity. The primary objective of the SCI program is to provide a software-only solution that enhances the integration and control of various aircraft systems, supporting the Army's broader modernization and interoperability goals. The FY 2026 budget marks the first year of procurement funding for this program.

The SCI program is managed by the Army and is designed to facilitate the seamless integration of new and existing aircraft platforms with advanced control interfaces. The specific goals for FY 2026 include supporting training integration, platform fielding, and user reach back support. By focusing on these areas, the SCI program aims to ensure that Army personnel are equipped with the necessary tools and knowledge to effectively operate and maintain the upgraded control interfaces.

One of the key objectives of the SCI program is to provide a flexible and scalable software architecture that can be adapted to a variety of aircraft platforms. This approach is intended to reduce the need for hardware modifications, thereby minimizing costs and streamlining the upgrade process. The software-only nature of the SCI program also allows for easier updates and enhancements as new requirements emerge or as technology advances.

A new start in FY 2026 is the Universal Products SCI, which is included as a subcomponent of the overall SCI effort. The Universal Products SCI initiative focuses on developing standardized software products that can be universally applied across multiple aircraft types. This standardization is expected to improve interoperability, reduce training and maintenance burdens, and facilitate more rapid deployment of new capabilities.

Procurement funding in FY 2026 is specifically justified by the need to support the initial rollout of the SCI program. This includes integrating the software into training curricula, fielding the platform to operational units, and providing user reach back support to address any issues or questions that arise during the early stages of implementation. These activities are critical to ensuring a smooth transition and maximizing the operational benefits of the new control interfaces.

Another important objective of the SCI program is to provide ongoing support and updates to users in the field. The user reach back support component ensures that operators and maintainers have access to technical assistance and troubleshooting resources, which is vital for maintaining readiness and minimizing downtime. This support structure is particularly important during the initial fielding phase, as users adapt to the new software interface.
