What project 673943 buys

The Space Domain Awareness Network effort is a Middle Tier Acquisition rapid fielding (MTF-RF) program of record. It is deploying a modern end-to-end data delivery capability via resilient, distributed mesh network capability for the Space Surveillance Network (SSN) and other associated sensor, C2 and data nodes. SDANet supports existing capabilities through improvements to end-to-end architecture and data delivery efficiency and resiliency to enable modern C2 and Artificial Intelligence/Machine Learning (Al/ML) initiatives. SDANet enables Sensor-to-Sensor, Sensor-to-C2 systems, and Sensor-to-Unified Data Library (UDL} end-to-end data flows revolutionizing the traditional vertical Sensor-to-C2 data flows to incorporate the ability to send and receive data laterally enabling space domain operations. Through a Mission Data Integration (MDI) initiative (Project Lighthouse), SDANet seeks to enable command-and-control (C2) through machine-to-machine interface between the Missile Defense Agency (MDA) and SDA sensors to allow USSPACECOM to deter aggression, defend national assets, and when necessary, defeat threats.

Project 673943 funding, FY2025–FY2031

Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

Inside the project

1 accomplishment / planned program

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

Named performers on project 673943

Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
