What frequency is used for military air distress communication?

The correct frequency used for military air distress communication is 243 MHz. This frequency is designated specifically for military aircraft to communicate distress signals. It is recognized as a part of the emergency frequency ranges and is utilized by pilot distress transmissions, particularly in situations where standard civilian frequencies may not be sufficient.

The 243 MHz frequency serves an essential role in ensuring that military aircraft can effectively communicate their need for assistance, enabling swift response and coordination from rescue units. This frequency operates in the UHF (Ultra High Frequency) range, which is ideal for air-to-ground communications, especially in emergencies.

While there are other frequencies, such as 121.5 MHz (which is primarily for general aviation and used for ELT signals) and 406 MHz (which is used for newer distress beacons), 243 MHz is specifically reserved for military use during distress situations. Consequently, it upholds the operational integrity of military communications and is critical for ensuring the safety of personnel in distress.
