US authorities have escalated security protocols for National Mall events to the highest level, deploying radiation-detecting aircraft and advanced drone-takeover technology to guard July Fourth celebrations.

The measures mark a significant increase in protective capabilities for the United States' 250th birthday weekend, reflecting heightened vigilance against potential threats.

The deployment of specialized counter-drone and surveillance assets aligns with recent market activity in the defense sector.

Drone stocks experienced a notable surge earlier this week, driven by reports that the Trump administration is in talks to fund several companies in the sector.

The Pentagon has reportedly been engaged in months of discussions with industry players regarding these technologies.

Former CIA director David Petraeus has previously warned that drone swarms represent one of the most significant security threats and structural growth opportunities in the defense sector over the next decade.
