Budget trajectory

The program's 3 summary figures for FY24 to FY26, plotted in fiscal-year order: 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.

Budget trajectory: one row per fiscal year, carrying the summary figure the sparkline plots. Every figure opens its own citation.

FY26	$45.3M

Decade view

P-1/R-1 workbook TOA basis, shown compact in $B/$M (the workbook records USD thousands); each figure cites its own President's Budget edition

7 fiscal years of this program as published (FY2020–FY2026): 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 rises across the span. 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.

● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

Decade series values by fiscal year and President's Budget edition: one row per series (actuals, enacted, request), one column per fiscal year. Every figure opens its own citation.
Series	FY20	FY21	FY22	FY23	FY24	FY25	FY26
Actuals	$0	$0	$18.4M	$36.6M	$54.9M
Enacted	–	$0	$19.1M	$35.1M	$64.2M	$80.0M
Request	–	–	$19.1M	$35.1M	$64.2M	$60.0M	$45.3M

blank = series not published for this year; – = absent from that edition.

Asked vs spent: the PB2024 book requested $64.2M for FY2024; the PB2026 book reported $54.9M as actual total obligation authority — $9.39M below the request. 54.85 − 64.24 = -9.39 USD millions — the compact figures above are rounded for reading.

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 — Counter - Small Unmanned Aircraft Systems Advanced Development

The Secretary of Defense (SecDef) designated the Secretary of the Army (SA) as the Department of Defense's (DoD) Executive Agent (EA) for Counter-small Unmanned Aircraft Systems (C-sUAS). The EA is tasked with leading, directing, and synchronizing DoD efforts to counter small Unmanned Aircraft System (sUAS) threats while minimizing unnecessary duplication and redundancy. C-sUAS efforts are aligned to DoD Joint Requirements Oversight Council Memorandums (JROC-M) requirements for identification, development, testing, evaluation, and integration of technologies to defeat sUAS threats. C-sUAS efforts provide warfighters the ability to comprehensively detect, track, identify, and defeat enemy Group 1, 2 and 3 sUAS platforms. Finally, these efforts include joint development efforts, industry demonstrations, and system operational assessments that provide integrated solutions to meet the needs of the Military Services and DoD Agencies against emerging threats.

Mission — C-sUAS Joint New Capabilities Development

Counter-small Unmanned Aircraft Systems (C-sUAS) efforts will demonstrate and support prototype efforts with technologies and concepts to enable and/or accelerate their transition to acquisition programs. The efforts will address technical gaps between initial technologies or concept development and quickly transition to warfighter capabilities. Efforts will explore new concepts and their applications in potential future operating environments within a systems-of-systems context. These joint prototyping efforts will inform future requirements and support Military Services' acquisition strategy planning to address the evolving s-UAS threats and new environments to which C-sUAS systems must be deployed.

Mission — C-sUAS Joint Enabling Capabilities Development

Counter-small Unmanned Aircraft Systems (C-sUAS) Joint Enabling Capabilities Development efforts will support the Joint C-sUAS Office in the development of materiel solutions to address joint capability gaps, support Military Service program management offices in conducting joint systems development, and minimize duplication and redundancy across the Services. These joint enabling efforts will inform future requirements and military services' acquisition decisions for C-sUAS materiel solutions to address evolving s-UAS threats and new operational environments where systems must be deployed.

Justification

Accomplishments & Planned Programs (4)

C-sUAS Prototyping New Joint Capabilities

Prototyping detect, track, identify, and defeat capabilities, to include command and control technologies, to fill C-sUAS capability gaps. Prototypes will address operational requirements identified by JROCM 058-23 and prioritized critical capability gaps identified by DoD C-sUAS Executive Agent Governance.

Joint Assessments and Demonstrations

Execute demonstrations and assessments of new C-sUAS technology to explore new concepts, new applications of existing systems, and new industry technologies. New concepts and technologies demonstrations will address future capability gaps and acquisition programs to maintain pace with evolving threats and employment environments.

Joint Prototype Assessments

Execute operational assessments for C-sUAS prototypes developed by the military services, and industry solutions showcased at JCO demonstrations. Prototype operational assessments will occur in operationally relevant environments, such as Geographic Combatant Command Areas of Responsibility, and utilize threat representative targets. Prototype operational assessment results will be leveraged by the military services to inform future acquisition decisions.

Joint C-sUAS Demonstrations

Execute demonstrations of industry C-sUAS solutions to explore new concepts, new applications of existing systems, and new industry technologies. New concepts and technology demonstrations will address future capability gaps and acquisition programs to maintain pace with evolving threats and employment environments.
