US Air Force Seeks Dronebuster Handheld C-UAS Devices for Space Force Base
The US Air Force has published a Sources Sought Notice seeking to procure handheld counter-unmanned aircraft system (C-UAS) devices for the 50th Security Forces Squadron (50 SFS). The 50 SFS is responsible for providing physical security, force protection measures, and law enforcement services at its assigned installation.
Procurement Specifications and Requirements
The notice identifies a specific system: the DZYNE Dronebuster DB4, configured with PNT capability, an LED array, and an accompanying kit. The initial deployment calls for two units to protect Schriever Space Force Base, with flexibility retained for follow-on procurement of additional devices.
The Air Force described the requirement as a critical and urgent need, stemming from the 50 SFS's obligation to establish an agile, modern counter-small UAS (C-sUAS) programme to secure the installation's airspace and safeguard critical assets against a growing volume of unauthorized drone activity.
The official notice stated: "If this requirement is not fulfilled, the 50 SFS will lack the necessary tools to rapidly respond to emerging UAS threats, leaving Schriever Space Force Base vulnerable to unauthorized surveillance or disruption."
Procurement Timeline
Delivery schedules will be determined based on the installation's immediate defense requirements, device availability, and scheduling flexibility for deployment. The Sources Sought Notice was published on SAM.gov on July 13, 2025, with a vendor response deadline of July 20, 2025.
Context
This notice follows a similar Dronebuster procurement request the Air Force issued earlier for Minot Air Force Base, signaling an accelerating push across US military installations to field handheld counter-drone capabilities in response to escalating drone incursion threats.
