Coast Guard-specific multi-mode radar

Also known as
  • AN/APY-11
  • AN/APY-11 multimode radar
  • APY-11 radar
  • AN/APY-11 multi-mode radar
  • APY-11 Surveillance AESA Radar

The Coast Guard-specific multi-mode radar is L3Harris's AN/APY-11 multisensor radar installed on HC-130J long-range surveillance aircraft during Minotaur missionization. Coast Guard and L3Harris sources describe it as a 360-degree belly- and nose-mounted radar for maritime surveillance, interdiction, search and rescue, ice and oil-spill mapping, and tracking ships, aircraft, vehicles, and rescue transponders.

Mission Fit

The AN/APY-11 is a sensor in the Coast Guard fixed-wing mission package rather than a standalone weapon. L3Harris describes the radar as a Coast Guard HC-130J system for maritime search, interdiction support, oil-spill mapping, ice tracking, and high-resolution radar imaging.

Aircraft installation

Belly and nose installation for 360-degree radar coverage on the missionized aircraft.

Mission system

Coast Guard contract releases tie the radar to future HC-130J aircraft during Minotaur missionization.

Track set

Ships, aircraft, ground moving vehicles, and search-and-rescue transponders are all named in the manufacturer description.
