Just to add some first hand knowledge from someone who operated into/out of IKA fairly shortly after the period in question
ADS-B being lost could of been down to loss of GPS signal and not related to the missile impact. We lost GPS signal in a very similar position, which subsequently led to the loss of ADS-B out.
And has happened to me pretty much every time I've departed there recently.
Also for departure we are always given the IKA 1A departure, which is basically rwy to 7000 the radar vectors.
Don't know if that's what they got, but seems every one normally gets that departure when I'm there.
