[[File:RWR.png|frame|This is IP-1150A RWR Azimuth Indicator used along with Raytheon (Litton) AN/ALR-93(V)1]]
Threat Warning Prime (TWP) is an utility panel placed just to the left of the RWR display which provides easy to reach functions and submodes for the RWR system. The Threat Warning Prime in conjunction with the [[Threat Warning Auxiliary Panel]], informs of the threats on the [[Radar Warning Receiver]].
Radar Warning Receiver (RWR) detects radio emissions from radar systems, it consists of several antennas, a processing unit, a radar library and an Azimuth Indicator (RWR display), and can be controlled by [[Threat Warning Prime|Threat Warning Prime]] or [[ Threat Warning Auxiliary|Threat Warning Auxiliary]] The main purpose is to issue warnings when a radar signal that may pose a threat is detected, such as a fighter jet's fire control radar. Warnings can then be used manually or automatically to circumvent detected threats. In addition, the distance of the emitter symbol from the center of the scope will not always be proportional to the actual distance, some ambiguities have been introduced.  
There have few variants for Threat Warning Prime use in the F-16s in difference variants, depending on what Radar Warning Receiver types its using, each Threat Warning Prime version having their own custom layout, button, function etc.
 
There have few variants for RWR use in the F-16s in difference variants, depends on the [[CMDS Control Panel|CMDS]] it uses, and each having their own custom modes of operation, azimuth indicator, sounds, controls and direction-finding accuracy.

''The BAE Systems (Loral) AN/ALR-56M is mostly replaced by Raytheon (Litton) AN/ALR-69(V).''
 
AN/ALR-56M can be receiver signal from [[Radar Band|C/D band]] (0.5-2 GHz) and [[Radar Band|E through J band]] (2 to 20 GHz), the direction-finding accuracy have '''15 degrees''' (E through J band); omnidirectional (C/D band).
 
It use IP-1310/ALR for the azimuth indicator (Image below). Note that this is not a monitor, but an [[wikipedia:oscilloscope|oscilloscope]].
