Threat Warning Prime

This is IP-1150A RWR Azimuth Indicator used along with Raytheon (Litton) AN/ALR-93(V)1

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). 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 RWR use in the F-16s in difference variants, each having their own custom modes of operation, azimuth indicator, sounds, controls and direction-finding accuracy.
Note: Different audio recordings may have varying volume levels.

BAE Systems (Loral) AN/ALR-56M

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 C/D band (0.5-2 GHz) and 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 oscilloscope.

Raytheon (Litton) AN/ALR-69(V)

Raytheon (Litton) AN/ALR-69(V) can be receiver signal from C/D band (0.5-2 GHz) and 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 same azimuth indicator as the AN/ALR-56M IP-1310/ALR(Image below) for the azimuth indicator. Note that this is not a monitor, but an oscilloscope.

Raytheon (Litton) AN/ALR-93(V)1

Raytheon (Litton) AN/ALR-93(V)1 can be receiver signal from C/D band (0.5-2 GHz) and 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-1150A for the azimuth indicator (Image below). Note that this is not a monitor, but an oscilloscope.

Element	Type	Position	Information

Elisra SPS-1000V-5

Elisra SPS-1000V-5 can be receiver signal from C through J band (0.5-18 GHz), the direction-finding accuracy have 15 degrees (C through J band).
The ELISRA SPS-1000V-5 is used in the IAF F-16C-30 Barak I.

Elisra SPS-3000

AN/ALR-56M can be receiver signal from C/D band (0.5-2 GHz) and E through J band (2 to 20 GHz), the direction-finding accuracy have 15 degrees (E through J band); omnidirectional (C/D band).
The ELISRA SPS-3000V is used in the IAF F-16C-40 Barak II and F-16C-52+ SUFA.

Thales Airborne Systems Carapace (TASC)

Thales Airborne Systems Carapace (TASC) can be receiver signal C through K band (0.5 to 40 GHz). Notably, it is the only RWR designed for installation in F-16s that offers exceptional direction-finding accuracy of 1 degree (C through K band) across these frequency bands.
The Thales Airborne Systems Carapace is used in the F-16AM Block 15 BAF.
