Iran's cheap drones are a drain on the U.S. weapons stockpile. Could lasers help fend them off?

TL;DR

  • Iranian drones, made from cheap materials, are a threat to U.S. weapon stockpiles and strategic locations like the Strait of Hormuz.
  • The cost disparity between Iran's low-cost drones (around $20,000) and U.S. interceptor missiles (millions of dollars per shot) is a major challenge.
  • AeroVironment's laser system, Locust, offers a solution with a cost per shot of about $3, drastically reducing defense expenses.
  • The Locust laser system has been deployed in multiple battles globally, including against drone threats like the Shahed drones.
  • The U.S. military did not initially anticipate the pervasive threat of drones hitting soft targets, despite being prepared for missile attacks.
  • Laser technology faces ongoing development challenges related to performance, accuracy, weight, energy requirements, and effectiveness in various weather conditions.
  • The U.S. Army is procuring Locust systems for border security operations, where they are used to intercept drug cartel drones.
  • Concerns regarding the potential interference of laser systems with commercial aircraft have been addressed through FAA testing, which demonstrated the systems' safety.
