The correct answer is TACAN, which stands for Tactical Air Navigation. TACAN is a navigational aid specifically developed for military aircraft to provide precise navigational information. This system combines the capabilities of distance measuring equipment with azimuth information, allowing pilots to determine their position relative to the TACAN station.

TACAN is particularly useful in military operations because it offers greater accuracy and reliability than other navigational aids, making it suitable for mission-critical situations. It operates in the UHF frequency range, which is less congested than the VHF range used by some other systems, enhancing its operational effectiveness during military missions.

Other options, while also serving navigational purposes, are primarily designed for civilian use or have broader civilian applications. For instance, VOR (VHF Omnidirectional Range) and NDB (Non-Directional Beacon) are widely used in commercial aviation but do not possess the specialized features tailored for military requirements. ILS (Instrument Landing System) is critical for precise landings but is similarly not designed exclusively for military use. Thus, TACAN stands out as the aid specifically crafted to meet the unique demands of military aviation.
