Ballistic Missile Defense Midcourse Defense Segment

Beginning in FY 2026, the Missile Defense Agency (MDA) is transferring the budget accomplishments for Ground Based Interceptor and Ground Based Interceptor Service Life Extension Program to a new budget accomplishment called Interceptor Fleet Management yielding a net decrease due to efficiencies gained from the fleet management approach. The Interceptor Fleet Management budget accomplishment will focus on sustaining a minimal workforce and infrastructure required to support the fleet, maintaining the existing fleet, ensuring fleet viability through execution of service life extensions, and executing repairs until the Ground Based Interceptors are retired or replaced by Next Generation Interceptors. Each Ground Based Interceptor delivers a single kill vehicle to counter allocated threats in space during the midcourse phase of the threat's ballistic trajectory. The Ground Based Interceptor project conducts the analysis and testing necessary to characterize the reliability and service life of the operational Ground Based Interceptor fleet and uses the data to support USNORTHCOM's development of shot doctrine. Recurring efforts in FY 2025 and prior include: - Collect and analyze operational Ground Based Interceptor fleet reliability, availability, maintainability, and testability data in order to support USNORTHCOM in management of the Ground Based Interceptor fleet and development of fleet-maintenance strategies. - Conduct testing to support analyses of Ground Based Interceptor performance against emerging threats. Specific and/or unique accomplishments to each FY are as follows:

The Ground Systems and Fire Control enables USNORTHCOM's command, control, and operations of the GWS as part of the Missile Defense System. The Ground Systems and Fire Control consists of the GFC, GCN/GNI, IDT, and GSS. The GFC consists of two (2) GFC nodes at FGA and at the Missile Defense Integration and Operations Center in Colorado Springs, Colorado. The GFC plans midcourse engagement and provides the human-in-control interface to the Warfighter. As a critical component of Ground Systems, the GFC supports decision-making and command execution. The GCN is the fire control network for the GMD Weapon System and network connection to the Missile Defense System. The GNI serves as a common secure platform to improve real-time cyber integration and the ability to detect and respond to cyber events. The IDTs are currently located at FGA (2); VSFB (2); EAS (1); and Ft Drum, New York (1), and provide communications from the GFC to the in-flight interceptors. The GSS consists of the Launch Support System and Missile Field / Launch Site Components located in FGA and VSFB and provides the hardware and software interfaces between the GFC and the Interceptors. Recurring efforts include: - Collect and analyze operational reliability, availability, maintainability, and testability data in order to support USNORTHCOM in management of the interceptor fleet and development of fleet-maintenance strategies. - Collect and analyze flight, ground, and cyber testing data in order to implement software and hardware updates, improvements, and fixes to address test findings. - Conduct design trade studies and engineering analyses to inform development. - Conduct analysis of design performance countering the allocated threats. - Conduct activities to support achieving Knowledge Points and milestone technical review entrance/exit criteria. - Approve parts, materials, and process requirements. - Conduct incremental delivery of the development, security, and operations software factory for continuous delivery and integration of software updates.
