Budget Trajectory
The program's 2 summary figures for FY25 to FY26, plotted in fiscal-year order so the direction of travel is readable at a glance: this line ends lower than it starts. The points are the summary cards above, not a separate derivation; the table beside the chart carries each figure with its own citation.

One fiscal year of this program as published: a line through the actuals (filled dots), with the enacted (hollow circles) and request (diamonds) markers each edition reported. Read it for direction, not for precision — this program's actuals line is too short to show a direction. The grid below is the same data as text, one cited figure per cell.

The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Description

Mission Spectrum Situational Awareness System (S2AS)

Spectrum Situational Awareness System (S2AS) supports Army key modernization initiatives by allowing commanders to sense and see themselves in the Electro-Magnetic Spectrum (EMS), preventing electronic fratricide, helping shape the electronic operating environment, and increasing Command Post (CP) survivability. Operationally S2AS allows commanders to determine and impact their visibility to enemy fire chain. S2AS is a dedicated EMS situational awareness management system that provides the Commander with real time EMS Situational Awareness to support Emissions Control (EMCON) decisions, Electromagnetic Interference (EMI) Resolution, and detect/warn operations centers of unauthorized or intentional sources of interference on today's complex battlefield. S2AS will employ sophisticated hardware and software to strengthen the capabilities of the Army and ensuring resilience against potential adversarial threat. S2AS will address current and future EMS challenges, ensuring awareness and secure use of the EMS. Enables integration, interoperability and force modernization with emerging capabilities in support of USAREUR-AF and USARPAC Operational Needs Statements, Transformation in Contact (TiC) initiatives, and Presidential Directives.

Oversight

Department-level designation (not specific to this program)

GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not Spectrum Situational Awareness System (S2AS) — no program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.

No research dossier for this program — dossiers cover 50 of 1,741 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
