The AN/MPQ-64 Sentinel automatically detects, tracks, identifies, classifies, and reports airborne threats in a range of 75 kilometers. This surveillance radar provides early warning to ground crews by supporting engagement of threats including helicopters, high-speed attack aircraft, cruise missiles, and unmanned aerial vehicles. Over 200 systems have been ordered world-wide, with more than 100 delivered or in production. Future evolutions currently in development include an 80% increase in the radar’s detection range.
