Ballistic Missile Defense Midcourse Defense Segment

GMD Systems maintain a defensive cyber posture through analysis of system software and hardware. By conducting annual cybersecurity reviews, all systems are evaluated to ensure the systems are authorized per the Risk Management Framework (RMF) to assess compliance in implementing and maintaining cybersecurity controls. GMD develops RMF assessment and authorization packages required to ensure all networks and nodes maintain an authority to operate. Recurring efforts include: - Assess, implement, document, and validate cybersecurity control families for representative systems comprising computing and logic bearing components to support the Development, Test, Training, and Operational systems. - Ensure compliance with security mandates to maintain continued authorization to operate. - Ensure the cyber workforce is trained and qualified. - Support modification of Installation Support Agreements for assigned real property to ensure Facility-Related Control Systems and supporting facilities are cyber-secure.

Cybersecurity and Cyber Resiliency efforts harden the system against a cyber-attack and reduce system vulnerabilities. The strategy implements cybersecurity and cyber resiliency systems throughout the life cycle to flow requirements to the Next Generation Interceptor and the weapon system to influence system development. Early cyber testing is completed to identify vulnerabilities and fixes early in the design process. Recurring efforts include: - Implement the cybersecurity risk process across all systems to execute risk-based decisions on cybersecurity controls. - Implement robust cyber resiliency by developing requirements that flow to component level designs, allowing the weapon system to operate in a cyber-contested environment. - Support testing on developmental systems in a virtualized environment by integrating cyber test events allowing execution of specific cyber threat vectors on developmental software in an effort to identify capability flaws that will be assessed through the cyber risk process. - Support Cooperative Vulnerability and Penetration Assessment to discover unknown vulnerabilities and determine effectiveness of mitigations from development level cyber testing. - Support Adversarial Assessment penetration to determine effectiveness of cyber-attacks in an operational environment along with the effectiveness of the operational and technical mitigations implemented from developmental cyber testing. - Implement software and hardware fixes to address weaknesses found during testing. - Develop intermediate cybersecurity processes and procedures that provide operators, maintainers, and Warfighter specific steps to recognize and react to cyber-attacks through defensive cyber operations. - Develop and execute quarterly cybersecurity training scenarios allowing fire control operators and network defenders to train in a cyber-contested environment while in an engagement scenario. - Provide training opportunities for fire control operators and cyber incident responders to test Tactics, Techniques, and Procedures. - Provide Risk Management Framework support to include authorization and assessment for the weapon system. - Support of cyber designs, integration, and test verification.

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.
