Where is the TACAN system located on a ship?

The TACAN (Tactical Air Navigation) system is typically located on the main mast of a ship. This positioning allows the system to have an unobstructed line of sight for effective operation. The main mast provides a high elevation that enhances the signal transmission range, which is crucial for enabling aircraft to receive accurate navigation information. Furthermore, the placement on the mast minimizes interference from the ship's structure and other electronic systems, ensuring reliable functionality during operations.

While the system could theoretically be placed in other areas of the ship, such as on the main deck or near the flight hangar, these locations do not provide the same advantages in terms of signal clarity and range. The control room would not be suitable because it needs to process information from systems like TACAN, rather than house the equipment itself. Thus, the main mast is the most effective and strategic location for the TACAN system on a ship.
