ARN-72 TACAN Radio

Introduction

The Tactical Air Navigation (TACAN) system is a navigational aid, capable of providing bearing and slant range in nautical miles to a beacon.

The AN/ARN-72 TACAN features a powerful receiver-transmitter that functions as an airborne interrogator-responser to provide range information to other AN/ARN-72 TACAN equipped aircraft, and slant range to surface beacons.
