NUDET Detection System (SPACE)

The NUDET Detection System (SPACE) program, managed by the Air Force, is designed to detect nuclear detonations globally in near real-time. This capability is essential for mission areas such as Integrated Tactical Warning and Attack Assessment, Nuclear Force Management, Space Control, Treaty Monitoring, and a classified mission. The program represents a collaborative effort between the Department of Defense and the Department of Energy's National Nuclear Security Administration. The Space Force's USNDS Program Office is responsible for acquisition and systems engineering activities related to space vehicles and their ground control segments.

A significant part of the NUDET Detection System is its space segment, which includes sensor payloads like the Radiation Detection Capability for Defense Support Program satellites and the Global Burst Detection payload for GPS satellites. These sensors are tasked with communicating nuclear detonation indications to ground segments such as the RADEC Data Processor and Integrated Correlation and Display System. The ground segment is being modernized through an incremental acquisition approach to continuously enhance its capabilities. This modernization includes upgrades to Ground Nuclear Detonation Detection System Terminals and the development of Universal Ground NDS Terminals.

The program emphasizes integrating new technologies through initiatives like ICADS 7, which involves upgrading satellite ground data processing systems to support new payloads on GPS IIIF satellites. This upgrade encompasses improvements in software, hardware, cybersecurity capabilities, and integration with new optical sensors. The program supports activities such as system engineering, testing, algorithm integration for different sensors, and ensuring system resiliency in contested space environments.

The NUDET Detection System (SPACE) program aims to deliver enhanced detection capabilities that meet survivable attack assessment requirements set by national defense authorities. It seeks to provide long-term solutions that support multiple military operations while ensuring compliance with treaty monitoring obligations. The program's development efforts are aligned with operational system upgrades that have been fielded or approved for full-rate production.
