The AN/TSW-7A is a tactical air traffic control tower that provides ground-to-aircraft, aircraft-to-ground, and surface communications within a designated tactical landing area or airfield. It is used for air traffic regulation, aircraft separation, in-flight assistance, and landing, takeoff, and ground control. Major components include AN/VRC-83 Have Quick radio sets, AN/VRC-92E SINCGARS radios, and one HF radio. The shelter is sling-loadable by a CH-47 or can be transported by a C-17. The AN/TSW-7A has metrological capabilities of measuring wind speed and direction, altimeter, current temperature, high and low daily temperature, and density altitude information.
