What is the maximum range of the AN/TPQ-37 Fire Finder Radar System?

• A. 50,000 meters
• B. 25,000 meters
• C. 75,000 meters
• D. 10,000 meters

Answer: (A)

The most important idea here is understanding what “maximum range” means for a fire-finder radar. It refers to how far away the system can reliably determine the source of incoming indirect fire, not how far a shell can travel. For the AN/TPQ-37 Fire Finder, the upper limit of that capability is about 50 kilometers, or 50,000 meters. This is based on its design to detect and track projectiles at long distances and use the trajectory data to back-calculate the firing position. In practice, the effective range can be influenced by terrain, weather, and clutter, but 50,000 meters represents the maximum capability under favorable conditions. The other distances are shorter than this system’s maximum, so 50,000 meters is the best choice.
