Overview
The AN/MPQ-64 Sentinel is a three-dimensional, phased-array radar system deployed all over the world. It operates in the X-Band frequency to automatically detect, track, identify, classify, and report airborne threats, including helicopters, high-speed attack aircraft, cruise missiles, and UAVs.[i] Sentinel has a range of 40 km (25 miles), and the upgraded version, first deployed in 2006, has a range of 75 km (47 miles). Given its range, which is several times that of short-range weapons, it works to provide early warning to ground crews and supporting maximum-range engagement of threats.[ii] The system can be integrated with a multitude of weapons systems, including Hawk, Surface Launched Advanced Medium-Range Air-to-Air Missile (AMRAAM), Stinger, antiaircraft guns, and other Short- and Very Short-Range Air Defense (SHORAD/VSHORAD) class weapons. The Sentinel command post can activate weapon control and pair incoming targets with the appropriate defensive weapon.[iii]
Strategic Implications
The AN/MPQ-64 Sentinel is a strategically valuable radar that offers the deploying country a distinct battlefield advantage. Just one Sentinel radar can track more than 50 targets simultaneously and can prioritize those targets.[iv] It also acquires targets far enough away to allow military forces enough time for their air defense weapons to engage the targets at optimal range and is almost impervious to electronic countermeasures. Lastly, the system includes an integrated identification friend or foe capability that helps prevent fratricide.[v]
