## What project 646438 buys

Joint Space Integration Technology leverages knowledge of the space environment and impacts on weapon systems to prototype, develop, test, and field joint multi-domain software and modeling solutions to fill capability gaps for Combatant Commanders. Military Application of the Space Environment (MASE) project consolidates and integrates current space environment science and technology advancements to provide capability for joint force systems in all domains to address immediate and evolving threats to U.S. forces operating in harm's way. The data provided supports rapid and agile demonstrations, exercises, and war games that provide essential validation of delivered capabilities to improve operational effectiveness. The FY 2026 spend plan amount for MASE includes 24,948 thousand of discretionary and 9,010 thousand of mandatory (reconciliation) for a total of 33,958. The FY 2025 spend plan amount for MASE includes 25,101 of discretionary. Additional details available at a higher classification. This program element may include necessary civilian pay expenses required to manage, execute, and deliver SCT weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 1206392SF and 1206398SF.

**R-3 lines of work:** Product Development; Test and Evaluation; Management Services.
