This document provides an overview of unclassified space-based and related programs requested in the Department of Defense’s (DoD) FY 2013 Budget in comparison with the FY 2013 NDAA and the FY 2013 Defense Appropriations Act. The first section provides a comparison of funding levels for major satellites and launch service acquisitions, followed by a more detailed analysis of each program. The analysis then looks at space-related provisions in the NDAA. An appendix at the end of the document provides a chart of unclassified DoD space and space-related programs organized by the various funding proposals. Please note the FY 2013 appropriations levels outlined in the Consolidated and Further Continuing Appropriations Act, 2013, do not take into account cuts from sequestration.
