Which trailer of the AN/MPN-14K LCC utilizes transceivers?

The AN/MPN-14K LCC, used primarily in military operations for air traffic control, has specific functional sections designed to handle various aspects of radar and communications operations. The trailer designated for Radar is responsible for processing and transmitting radar signals to ensure accurate tracking of aircraft.

Transceivers, which are devices that can both transmit and receive signals, play a crucial role in radar operations. In the case of the AN/MPN-14K LCC, the Radar trailer contains the necessary transceivers to facilitate communication between the radar systems and the control units. This setup enables the radar to transmit its findings and also receive commands or data, which is essential for effective operation in air traffic control scenarios.

The Operations (OPS) trailer focuses more on command and control functions, while the Maintenance trailer is dedicated to repair and upkeep of the systems rather than signal processing. The Communications trailer, although it does involve transceivers, is not the primary operational component for radar functions as defined in this context. Thus, the Radar trailer is specifically equipped with the technology necessary for radar signal transmission and reception, making it the correct answer.
