Description
Description — Space Digital Integrated Network (SDIN)
The Air Force created the Space Digital Integrated Network (SDIN) in the 1980's as the Air Force Space Command (AFSPC) Space Defense Interface Network. While it was built to support communication between Missile Warning/Missile Track (MW/MT) sensors and Command and Control (C2) nodes to support nuclear deterrence and missile defense of the homeland, it has grown to support every Space Force mission area with connections to almost all Space Force operating locations. This includes Space Domain Awareness (SDA) sensors, MILSTAR Family of Advanced Beyond Line-of-Sight Terminals (FAB-T) communications, Space Based Infrared System (SBIRS) ground segment communications, intra-base and inter-base communication between SOCs and other force elements, Defense Red Switch Network (DRSN) long local communications, Land Mobile Radios, and more.
Justification
Justification — Space Digital Integrated Network (SDIN)
This program is a new start. This program is an FY 2026 New Start. Space Digital Integrated Network (SDIN) - Modernization: The Air Force modernized some of legacy 1980's SDIN hardware in 2012 to mitigate obsolescence, but some of the equipment is once again nearing end of life. The Space Force needs to modernize the network technology to ensure continuity of operations. Starting in FY26, the Space Force will perform architectural analysis, hardware procurement, integration, and installation activities to modernize this critical network.
