If you have no other means of downing drones, then OK. At 60-65000dollar per hour (remember with extra tanks and refuelling, a typhoon can fly 9-10 hours) .
That is well over 600thousand dollars, plus cost of munition, spent to shoot down slow moving cheap drones.
If you have your UCAVs like TB3, Anka, Akinci that have over 24 hour endurance or Hurkus to intercept then why fly those expensive jets for drone shooting duties? At worst send a KE to intercept.
To me that is rich man’s solution for a cheap problem.
