Navigation & Communication

The AN/ASN-63 Inertial Navigation System (INS) equips the F-4E aircrew and integrated weapons delivery system with real-time accurate positional, velocity, attitude, and heading information.

The UHF communication system in the aircraft is modified to support both crypto and conventional voice transmission and reception. The intercom system and UHF transceiver are adapted for operational compatibility with the KY-28 speech security unit.

The VHF Omnidirectional Range Instrument Landing System (VOR/ILS) furnishes accurate bearing and course deviation information through a ground station transmitter. This system enables the aircraft to utilize precision landing approach and descent capabilities at fields equipped with a localizer.

The Tactical Air Navigation (TACAN) system offers bearing and range information to transmitting stations, with a reception range of up to 390 miles from ground stations and 200 miles for air-to-air TACAN-equipped aircraft.
