What we know about the new RWR system

On the DEV server, the aircraft RWR seems to get the same performance as the real one.
Here I will write down the information I obtained from datamine and actual play.

(I don’t have a top aircraft such as the F16 yet, so there may be some information missing.)

  1. Restricted zone decomposition in receive direction
    Depending on the RWR, the direction in which the radio waves were received can only be vaguely expressed. This is noticeable in Soviet-style RWRs.
    The western RWR generally has fine zones.

  2. Some do not have lock-on warnings.
    Some older RWRs cannot detect the characteristic lock-on radio wave and cannot emit the lock-on warning sound. In order to judge lock-on with such RWR, it can be judged by the reaction symbol on RWR starting to light up continuously instead of blinking.
    You can see this on the F-4j, F-5C, etc. As you can see when you play, it’s horribly difficult.

This image is in the state of receiving lock-on from Mig29. No warning sounds!

  1. It is possible to analyze radio waves and compare them with a dictionary to determine the threat of the source.

    A warning light that informs you of the rough threat of radio waves


An advanced function that displays the direction of radio waves and the model.

First, let’s explain the warning lights. The warning light tells you what category the radio waves directed at your aircraft belong to. This information depends on the amount of information in RWR’s internal dictionary. That is, older generation aircraft cannot warn of new weapons. For example, only the ZSU-37 can be warned about the F-4J’s RWR as SPAAA, and other SPAAAs cannot be warned as SPAAA.

Another thing is that the information on this warning light is not related to the direction of the radio wave transmission. For example, if you are locked on from the front and the right at the same time and the SPAAA lamp lights up, it will not be possible to determine whether the SPAAA is from the front or the right. It could be one or the other, or it could be both.


The information indicated by the warning lights is listed below.

  • AI (aircraft “lock-on” radar)

  • CW (CW radio waves emitted by aircraft when guiding SARHM. When this lights up, it indicates that Sparrow etc. are approaching. Phoenix’s active radar is also included in this)

  • PD (indicates that the radar that emitted the received radio wave has PD mode. It is unknown whether the other party is actually using PD mode)

  • AI/RO (Aircraft ranging radar: Receives low-function radar installed in F-86, etc.)

  • AAA (Lock-on radar of SPAAA on the ground)

  • SAM (ground-based SAM lock-on radar)

  • A/D (lock-on radar for ground-based anti-aircraft weapons (both SAM and SPAAA)

  • Other warning lights that are not used (There are warning lights for weapons that do not appear in WT, such as the hawk and SA-75. These do not work.)


Next, we will introduce the function to display the model on the RWR circle.
This function uses the dictionary inside RWR to identify the detailed model of the vehicle that emitted the radio wave and displays it on the RWR circle.

For example, when receiving a radio wave from a Mig-29, the abbreviation M29 will be displayed on the RWR, and the direction of the radio wave can be identified by the position where the letter is displayed.
This function currently does not allow detailed classification such as whether the opponent is an F-4C or an F-4E.

You can identify and display not only aircraft, but also ships, ground objects, missile active radars, and more.

The amount of models that can be identified is determined by the amount of information in the dictionary. In other words, there are differences between countries and ages.
Currently, the only way to find out what models can display it and what abbreviations they use is through Datamine.

This function coexists with the warning light mentioned above. So use the warning light to identify an impending threat, use the RWR circle for more information, and so on.

This is the new information I know about RWR. If you have any other information or things that are wrong, please keep posting on this topic.


One new fact. The second phenomenon that the lock-on warning does not sound is that “the lock-on warning sounds only when a lock-on signal registered in the RWR dictionary is detected.”

The F-4J’s RWR cannot detect a MIG-29 lock, but it seems to sound a warning if it is an old MIG-21 lock.

However, since lock-on is basically carried out using a similar mechanism in all eras, it should be possible to detect lock-on even from new generation aircraft unless the RWR band is clearly out of range. …


Also, in the modern nato RWRs (F-16, F-14, Mirage2000, etc.) when a missile is fired during an hardlock, the lock signature will start blinking. There is still no sound warning for a missile launch

new information
WT radar has a band concept, and each radar has a set radio wave band.

RWR also has a corresponding band range setting, and radio waves from unsupported bands cannot be received.

However, until now, WT has set the band within RWR, but the RWR band limit has been intentionally turned off by the game setting.
In this DEV, it was confirmed that this RWR band restriction is turned on.

The SPO-10, a common early Soviet RWR, can only receive band 8. In WT, Band 8 is commonly used by airborne radars. However, since SAM and SPAAA on the ground use different bands, aircraft equipped with SPO-10 cannot receive search waves and tracking waves emitted from objects on the ground. (It seems that there are some ground objects and ships that use Band 8. For example, the warship Bussalt that appears in the German test flight uses Band 8 for its tracking radar, and SPO-10 responds to it.)


That’s very interesting fr. Thank you for continuing this topic

In DEV server version 2, detailed RWR information is now displayed on the X-ray status card, so I will write down the details obtained from the datamine.
This information is based on speculation and may be incorrect.

The Band column shows the radio wave band that RWR supports. RWR cannot receive any radio waves from radars using unsupported bands. However, this rule is ignored only in AB.
Describe the major bands.
  • Band I
    This is the most common band used by airborne radars. Some ground objects may use it. Early Soviet RWR only supported this band.
  • Band J
    Mainly used for ground vehicle tracking radar.
  • Band E
    Mainly used for ground vehicle search radar.
  • Other irregular bands
    Some older aircraft and ground vehicles may use special bands. In particular, ships’ radars seem to use different bands.



This is a guideline for the radio wave strength that RWR can receive. The possibility of reception probably changes depending on the output of the other party's radar, so I don't know if it can actually be received at the displayed distance or if it is just a guideline.

3.Threats types

Indicates the number of radar types registered in the RWR internal dictionary. Radio waves from radars that are not listed in this dictionary can be received as long as the band matches, but lock-on or firing by that radar cannot be detected as a warning.

If this field is set to “Unlimited”, as long as the RWR band matches regardless of the internal dictionary, there is a possibility that lock-on warnings and missile launch warnings can be issued for all radio waves.

However, whether RWR has a alarm function depends on the value in the column described below.

For now, the dictionary breakdown can only be found on Datamine.

4. Tracked threats (option)

This field is displayed only for RWRs whose model symbol can be displayed on the RWR circle. Meaning is the maximum number of symbols that can be displayed simultaneously on the RWR circle.


The characters 2S6 in this image are called symbols.

5. Tracking threats types (option)

This column shows the performance of the RWR lock-on alarm.
  • If the value in this field is “1”, the lock-on warning will only work on radars registered in the dictionary.
  • If this column is “Unlimited”, the lock-on alarm will work if it is a radio wave of the corresponding band.
  • If this field is not present, there is no lock-on alarm for that RWR.

6. Launching thereats types (option)

This column indicates the performance of the RWR missile launch alarm.
  • A number greater “than or equal to 2” in this column indicates the number of radar types for which the RWR can issue missile launch alarms.
    This relies on an internal dictionary, the breakdown of which can only be found in the datamine.
    This display appears when Threats types are “unlimited”.

  • If the number in this column is “1”, the RWR can only issue missile launch alarms for radars listed in the dictionary used in the “Threats types” above.

  • If this field is “Unlimited”, missile launch alarms can be issued for all radio waves.

  • If this field does not exist, the RWR does not have missile launch alarm capability.

7. Identified threats on scope (option)

This column shows the number of symbol types that RWR with symbol display function can display. The meanings of symbol types and abbreviations depend on an internal dictionary and can only be checked in the datamine.

This field is not displayed for RWR without symbol display function.

8. Identified threats (option)

This column shows the number of warning lights that appear below the RWR circle.

This column is not displayed for RWRs that do not have warning lights.



Doas someone know how to read the rwr coverage Data

you mean RWR detection range?

Can you specify what do you mean?

No angles they can detect
360 degrees left right up down
Or just rear aspect only

Because my mig23ml could not detect anything in Front aspect on the dev Server

I don’t think it was stated in the statcard, so you need either datamine or figur it out. It is the same for the side angles (by that i mean if you are in level flight, enemy radar is on the same lever 90 degree to your side, how much you can roll untill it stops detecting).

That might be an issue with the radars you tested it against. From a quick look from the datamined files:

The SPO-15 can detects bands 6, 7 and 8 which corresepond to bands G, H and I and has 10 receivers. Left and right are symmetrical, so I will just list one side:
Listed in order: angle from front middle line, azimuth coverage, elevation coverage

  • 10°, 20°, 60°
  • 30°, 20°, 60°
  • 50°, 30°, 60°
  • 90°, 50°, 60°
  • 150°, 65°, 60°

So it should be able to detect thing from the front, unless they more than 30° below or above you and/or their tracking signal is out of your RWR coverage (might be the case for ground radar).
