Merops counter-drone interceptor

Also known as
  • MEROPS

  • Merops counter-UAS system
  • Merops drone interceptor
  • AS3 Surveyor
  • AS-3 Surveyor
  • Surveyor interceptor
  • Surveyor interceptor drone

Merops is a U.S.-developed mobile counter-drone system from Perennial Autonomy that launches Surveyor interceptor drones from a truck-portable package. Public reporting ties the system to Ukrainian counter-Shahed use, NATO eastern-flank fielding in Poland and Romania, and U.S. deployment during the 2026 Iran War. Its profile centers on AI-assisted guidance in jammed environments, pickup-truck mobility, and a roughly $15,000 interceptor cost.

Role in Conflicts

Defense News reported that Ukrainian forces first used Merops in June 2024 against Russian-operated systems including Shaheds, while NATO and Business Insider reporting described large-scale Russian or Shahed-type drone intercepts in Ukraine.

Role details

AP and Army reporting said Merops was sent to the Middle East during the 2026 Iran War to bolster defenses against Iranian drones; Business Insider later reported U.S. soldiers operating Merops complexes at two regional sites, with no confirmed Iranian-drone kills disclosed as of April 13, 2026.

Launcher And Interceptor

Public sources describe Merops as an operational complex built around a small Surveyor interceptor, launch equipment, a ground control station, radar, and supporting sensors.

Interceptor

Surveyor is reported as a few-feet-long propeller-driven interceptor that can be carried by a single soldier and launched from a truck-portable package.

Supported by Business Insider and Inside Unmanned Systems reporting.

Engagement

Sources describe AI-assisted navigation in jammed environments, radar/RF/thermal or electro-optical targeting inputs, and either direct collision or proximity-effect defeat of hostile drones.

Supported by AP, NATO, Defense News, and Business Insider reporting.

Deployment

Merops can be launched from pickup-mounted or fixed launch stations, giving operators a lower-cost counter-UAS layer for Shahed-type one-way attack drones.

Supported by NATO, Army, AP, and Business Insider reporting.
