Drones dropping stuff off in prison...Its way longer than a year. And anyway, catapults were being used before that, and catapults are being used again. Best solution was the netting.
Very low cost drones have been used to attack Russian airbases (at least) in Syria and drones have been used a lot in Iraq - and were very effective to begin with.
The latest Nagarno-Karabakh conflagration saw An2s converted in to drones and filled with explosives (pilots performed take off, set them on cruise and then parachuted out of them) along side other drone products.
Its an extremely pervasive technology.
