Budget Figures
FY2026 award data is a partial year — USASpending awards are reported on a rolling basis and the fiscal year does not close until September 30. why partial FY2026 data? →
| Fiscal year | Amount |
|---|---|
| FY25 | $4.67MR-1 TOA · PB2026 |
| FY26 | $0P-40 detail · PB2026 |
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.
● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.
| Series | FY25 |
|---|---|
| Enacted | $4.67M |
| Request | $9.33M |
blank = series not published for this year; – = absent from that edition.
Program Lineage
No predecessor/successor lineage was recorded for this program element — no FY-to-FY transfer into or out of this line was stated in the ingested J-books, and none was inferred from the program structure.
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? →
