U.S. Army requests nearly $1 billion to defeat small drones

The U.S. Army has requested $994 million for counter-small unmanned aerial system capabilities in its Fiscal Year 2027 budget — a figure that reflects just how dramatically the drone threat has reshaped ground force priorities over the past three years.

The request, recorded in the Department of the Army’s official FY 2027 President’s Budget Exhibit P-1 released in April 2026, places counter-drone defense among the Army’s largest single equipment investment lines in the Other Procurement account.

The number itself tells a story of accelerating urgency. FY2025 actuals for the same program — designated Counter Small Unmanned Aerial System, or C-SUAS — came in at $543 million. The FY2026 total reached $596 million, combining enacted discretionary funding with supplemental spending under the PL 119-21 reconciliation mechanism. The FY2027 request of $994 million represents a jump of roughly 67 percent over FY2026, and nearly double what the Army actually spent on the program two years prior. No other budget line captures how rapidly the Pentagon has been forced to adapt to a threat that barely registered in Army procurement planning before the war in Ukraine began.

The Counter-UAS program covers a family of systems designed to detect, track, identify, and defeat small drones — the kind of commercial and military unmanned aircraft that have transformed the battlefield in Ukraine and, more recently, in operations across the Middle East. These are not the large, expensive drones that air defense systems were built to handle. They are small, cheap, often commercially available quadcopters and fixed-wing aircraft that can carry explosives, conduct reconnaissance, or swarm in numbers that overwhelm traditional defenses. Defeating them requires a different toolkit entirely — one that blends radar, radio frequency sensors, electro-optical cameras, electronic jammers, and in some cases kinetic interceptors, all integrated into systems that soldiers can actually operate in a combat environment without a dedicated air defense battalion standing by.

The Army’s Counter-UAS portfolio includes systems at multiple echelons, from vehicle-mounted and base protection systems to man-portable solutions that individual infantry units can deploy. The investment is not about buying a single silver-bullet system. It is about fielding enough capability across enough units that small drones stop being an asymmetric advantage for whoever uses them against American soldiers.

Ukraine made the case for that investment more viscerally than any Pentagon briefing could. Ukrainian and Russian forces have both used drones at a scale and tempo that no military planner had fully war-gamed before 2022 — dropping grenades on individual fighting positions, hunting armored vehicles, directing artillery fire in real time, and conducting one-way attack missions against targets deep behind the front line. The lesson absorbed by armies watching that conflict was straightforward: if you do not have a credible answer to small drones, you are vulnerable in ways that no amount of conventional firepower can compensate for.

The FY2027 request sits within a broader Army missile and air defense investment surge. The same P-1 document records a separate line for Counter Small Unmanned Aerial System Intercept under the Missile Procurement, Army appropriation — the kinetic side of the counter-drone equation, covering the actual interceptor munitions used to shoot drones down. FY2025 actuals for that line reached $329 million. Together with the $994 million Counter-UAS equipment request, the combined Army counter-drone investment in FY2027 runs well past the billion-dollar mark across the two appropriations.

The broader air defense picture in the FY2027 Army budget is substantial. The Indirect Fire Protection Capability Inc 2-I program — a system specifically designed to defeat cruise missiles, drones, and rockets at the brigade level — is funded at $1.626 billion. M-SHORAD, the short-range air defense vehicle designed to protect maneuver forces from low-altitude threats including drones, receives $712 million. The Army is essentially building an entirely new air defense architecture from the ground up, oriented not toward Cold War scenarios involving Soviet aircraft but toward the proliferated drone and missile threats that have defined every major conflict of the past three years.

The FY2027 C-SUAS request now moves through the congressional authorization and appropriations process. Given the consistent year-over-year growth in this program and the bipartisan recognition of the drone threat, it is among the Army’s budget lines least likely to face significant cuts.
