I did some test flights last night myself and posted the videos over the UK typhoon thread but you can see the same behaviour on the Sea Harrier’s Blue Vixen and the Tornado’s Foxhunter. The Gripen too though I haven’t taken video of it and the Su-33/Mirage 2000 in test flight (I don’t have the US tree at top tier to test those planes).
Honestly I kinda suspect that something is broken on all TWS radars, it’s just most apparent on the radars with a slower scan rate.
What exactly is wrong here?
If you are talking about the radar contact going away from the target, than that is normal.
TWS finds the position of the aircraft and its velocity vector. It then just shows you the position of the aircraft if it were to continue traveling at the same speed in the same direction.
The MiG-15 in your video is flying away from you at an angle and slowly turning towards you. So the TWS track looks as if it is lagging behind. The MiG-15 is turning to the left, so naturally its position on your screen is moving the left more than the TWS track that continues flying straight.
Near the end of the EFT clip, the MiG-15 is already flying perpendicular towards, so now it turning decreases its angular velocity. This makes it look like the TWS track flies off the the left.
Also, you are zooming in with the camera, making the effect even more apparent.
With faster scanning radars, the target’s position and velocity get updated more frequently, so target does not deviate from the track file that much.
AIM-9M was issued for the German Eurofighter to keep it with a smokeless AIM-9 variant. Since it was found that sadly AIM-9L/I-1 doesn’t have a smokeless motor option.
Diehl BGT Defence sources confirm it has Mk.36 Mod 8/10 motor.
And according to AVIA 18/4731, the Mk.36 Mod 8/10 motor is not smokeless. Only Mod 9 and 11 motors are filled with a reduced smoke propellant which can be fitted to AIM-9M.
It’s normal yeah, but speaking purely ancedotally here I swear it’s much more pronounced then before the update. It’s nothing you can’t overcome with the narrow tws scan pattern but the sheer amount of drift on the wider scan patterns is rendering them unusable.
well according to

there’s multiple guidance control sections.
most notably the M-8 which “[incorporates] electronics processing modifications to improve the tracking capabilities against modern Infrared Countermeasures (IRCM)”
compared to the M-1 and M-3. to be precise, the WGU-4E/B GCS
It’s a standard AIM-9M with reduced smoke motor, but is fired at high altitude where the exhaust plume becomes quite visible. Late AIM-9L examples used the reduced smoke motors first, all AIM-9M are produced solely with reduced smoke motors.
It is possible that an AIM-9M has been equipped with a high smoke motor modification during maintenance, but it is unlikely.
