Others are pointing out present issues with drones, but it seems that an airframe that doesn't have to carry a human or human support systems leaves many more degrees of freedom for optimization toward any set of airborne design goals than one saddled by carrying a human. I'd be highly surprised if there weren't air defense drones on drawing boards around the world right now.
