Laser weapons require too much power, so the best bet is a way to lure the threat to where you want it.
But a micro-anti radiation missile could homing in on the seeker of a long range BVR missile, to get close enough to fire its proximity fuse. Possibly the electronics from a towed decoy put on a very maneuverable WVR missile body could do the trick and destroy the missile far enough out to prevent shrapnel from damaging the platform.
It’s also possible the KAAN will carry 4 towed decoys the way the F-35 does. Does Türkiye make a towed decoy (preferably one trained against the S-400 and Rafale)? Türkiye as originally a F-35 partner (and potentially a future operator) would have a head start on developing its own version of this concept.
Ever missiles with IR seekers could be blinded with a high speed pulse of laser energy if the weapon can quickly detect and focus enough energy that direction.
So orienting the development of the HK-DAS missile would be best suited against IR guided WVR missiles. Extreme maneuverability within a fraction of a second and within 5 km.
