again in January this image was shown while on board the Tunan class corvette it was carrying out fire tests, in red I circled one of the two MR-104 Rys (Drum Tilt) fire control radars (the other is at the stern of the ship ) this radar is commonly used for the AK-230 and AK-630 CIWS,Honestly if that turns out to be the case I hope they make SPAAG using the turret with added radar on it.
but in the past the Myanmar Navy had already adapted it as fire control for the OtonMelara 76.62 on the 771 corvette (later replaced by the other device).
Now looking at the photo the attached Drum Tilt radar on the North Korean corvette is turned in the same direction as the similar NK made compact 76/62, this leads me to think that the North Koreans have adapted this radar for use in this turret, so it can be also used to direct anti-aircraft fire.
Radar that could be modernized thanks to the digitalization of the devices that compose it.
