The "AN/TPQ-53" Counterfire Target Acquisition Radar, also known as Q-53, is a C-130 transportable, truck-mounted Counter Target Acquisition radar system configured to provide 360-degree threat detection capability manufactured by Lockheed Martin in the United States. It is able to locate the firing positions of both rocket and mortar launchers. The Q-53 development was informed by earlier versions of a similar technology called the "AN/TPQ-36" and "AN/TPQ/37" radar systems. The AN/TPQ-36 required three trailers, three vehicles and a six-man crew; the Q-53 requires a four or five-man crew and includes a 60-kilowatt transportable generator and one support shelter vehicle. Q-53 uses an encrypted wireless network able to reach up to 1,000 meters away
