Congress examines rising threat of unauthorized drone flights over US critical infrastructure

The U.S. House Committee on Homeland Security convened on July 16, 2025, to discuss the implications of drone warfare abroad and its impact on domestic security. The meeting highlighted the increasing threat posed by unmanned aircraft systems (UAS) and unauthorized drone activities within the United States.

The session began with a focus on the realistic threats from adversaries utilizing drones for pre-conflict activities, such as mapping soft targets and collecting intelligence. Experts noted that these tactics are already in use, particularly along the U.S. borders, where cartels and other groups are actively employing drones to monitor patterns of life, including the movements of law enforcement and government officials. This surveillance extends to critical infrastructure, including airports and prisons, where drones are reportedly being used to gather information on guard shifts and security protocols.

A significant concern raised during the meeting was the alarming number of unauthorized drone flights over sensitive sites. In the past two years alone, there have been over 3,000 unidentified drone incursions near power plants, with no clarity on the intentions behind these flights. Additionally, the Federal Aviation Administration (FAA) reported more than one million registered drones in the U.S. as of April 2025, with many more believed to be unregistered. This surge in drone activity has raised alarms, particularly near military installations and nuclear facilities, where over 600 unauthorized overflights were documented between 2022 and 2024.

The discussion also addressed the potential cascading effects of unauthorized drone overflights at military facilities, airports, and maritime ports. Experts warned that while no catastrophic incidents have occurred in the U.S. to date, the risk remains significant. Each unauthorized flight not only poses a potential threat but also erodes public trust in drone technology. This decline in confidence could jeopardize the positive applications of drones in public safety and economic sectors.

In conclusion, the meeting underscored the urgent need for enhanced security measures and public awareness regarding the threats posed by drone technology. As the landscape of drone warfare evolves, so too must the strategies to mitigate its risks at home. The committee plans to continue exploring these issues to ensure the safety and security of U.S. citizens.
