A - That drone is a lot bigger than what you have posted.
B - Even if you manage to get the gun in the air the battery life will barely be enough to do a operation with it.
C - The recoil problem is still not solved and will probably not gonna get solved since you have nothing to counter horizontal forces like a fixed wing plane. Now you will probably take gun ships as exsample since you are so smart but keep in mind the weight ration between the aircraft and the gun producing the recoil.
A) Sorry, nope. Check other timelines of the video i posted above, you can make a comparision of the width of the drone and width of the person, than compare it with the Star Wars drone picture in previous page.
B) I know the limitation of the operation time, its possible to increase operation time to 3 hours, but increase it to 5-6 hours is not simple. It could still be useful against Terrorist targets in cities/or open field though.
C) Recoil wouldn't be a big problem though, if we use 7.62mm gun on Sarp-L. 12mm would be a bad choice on 200kg air platform.
So how do you fix latency issues, even RWS that is hard wired have noticeable latency.. Getting a UAV with a Cannon on it to send/recieve imagery and command data via a wireless connection would be impractical. Some sort of semi-autonomous targeting system would have to be developed, and then there's possibility that the SA-AI would not be able distinguish from civilian/friend/foe... Highly impractical to have a weapon station, better to have couple Cirit missiles..
Well my only experience with drones was amateur small RC planes so i have no idea of latency issue of the drones that as far away as 150km
But Aselsan's Sarp system has pretty good targeting system on it;
The advantage of rotatory wing drones, it doesnt have to move while targeting the enemy units. It can basicly hover 2 km above the target, and lock on the enemy unit. For example, check this video;
watch after 0:19. Helicopter takes footage of the terrorists in the streets, but couldn't engage (possibly police helicopter). So you have to send one attack chopper to there to neutralise them, and if chopper got hit you will lose tens of millions usd. Instead, if you have small drone that can carry Sarp-L like i mentioned, you send few of them and you dont only take footage of the terrorists, but engage them with weapon station and neutralise them.
You cant use Bayraktar or ANKA UAV for this mission since they are fixed wing aircrafts and they travel fast, they would pass the target in few seconds and will lose the view angle of the streets in miliseconds, let alone engaging the targets with guided munitions which would hit the buildings around the street instead of real targets, since the street is so narrow
Mentioned drone is so cheap, could be as cheap as 4-5 UMTAS missile price. So if you lose it, it won't be a big problem in economic side, and there wont be any pilot loss.
Same example can be given for FSA's assoult on Tel-Rifat. They ambushed earth barriers of PKK, they lost dozens of fighters and few armored vehicles to PKK because they didnt have any capability to hit the enemy targets from above. You can send few drones even if SAA or Russia don't allow you to, since the possible loss of the drones isnt a big deal, and they would be a game changer since they easily hunt the terrorists behind the earth barriers.
