Every bit of information I am finding (Chinese sources) says it has around 33-50% more range than the AGM-65, so it is a Kh-38 equivalent by that standard.
Yeah, if they are being added for a SEAD gamemode then I can understand, though it does seem out of place considering the game’s limitations with weaponry at the moment. And yes, the Kh-38MT would still be used over an IR Kh-59 because it still out ranges all SAM’s in game, and is considerably faster.
Main question is how long motor working.
