AN/TPQ-53 Quick Reaction Capability Radar

AN/TPQ-53 Quick Reaction Capability Radar is a mobile counter-battery radar system manufactured by Lockheed Martin. The Radar is specifically designed to locate the firing positions of both rocket and mortar launchers. The TPQ-53 radar's delivery on July 2 followed its successful live-fire performance testing against indirect fire from mortars, artillery and rockets from a simulated enemy. The system has been tested and has been accepted by the US Army. TPQ-53 radar systems will replace the aging TPQ-36 and TPQ-37 medium-range radars now in the Army's inventory.

Prior to September 2011 This system was known as EQ-36 Counterfire Target Acquisition Radar.

In June 2013 the United States Army exercised a contract option to finish out the total production of 51 systems.

Per the Joint Electronics Type Designation System (JETDS), the nomenclature AN/TPQ-53 is thus derived:


 * "AN/" indicating Army/Navy(Marines)--a system nomenclature derived from the JETDS
 * "T" for 'transportable', indicating it is carried by a vehicle but is not an integral part of said vehicle (compare with 'V' for vehicle-mounted).
 * "P" indicating a RADAR.
 * "Q" for a special-purpose/multipurpose radar, in this case counter-battery.
 * "53" is the model number of this radar within the TPQ radar family.
