AN TPQ-37 Firefinder Weapon Locating System
The AN/TPQ-37 Firefinder radar system quickly locates long-range artillery and rocket launcher positions beyond those weapons' maximum effective ranges.
The “Big Brother” to the TPQ-36, this Weapon Locating Radar automatically detects enemy long range mortars, artillery and rocket launchers out to a range of 50km and directs fast accurate counter-fire on up to 10 targets simultaneously. It is in use by nations worldwide and is a mainstay of the U.S. Army long-range Artillery.
