Why is the U.S. government exploring using high-energy lasers near the southern border?

TL;DR

  • A temporary flight ban near El Paso was caused by federal government disagreements over using a high-energy laser weapon system to take down drones.
  • Customs and Border Protection (CBP) used the laser system, despite the Federal Aviation Administration (FAA) having safety concerns.
  • The system detects aerial threats and uses a laser beam to damage or disable targets like drones.
  • During testing, the high-energy laser system took down at least one party balloon instead of a drone.
  • Drones, primarily used by cartels for surveillance and smuggling, are a persistent problem along the U.S. southern border.
  • A joint task force is working to coordinate federal agencies in countering drone threats.
  • Experts suggest a layered defense system, including radio frequency cyber techniques and high-energy lasers, is necessary.
  • The initiative highlights the need for better communication and coordination between the FAA and the Department of Defense (DOD).
