Deck-based UAV for anti-submarine warfare The Turkish Bayraktar TB3 UAV has reached a new stage in the development of naval aviation. The device first took off from the Anadolu Universal Landing Ship and used deployable sonobuoys to search for underwater targets. Buoys can detect and track submarines by transmitting data about the underwater situation to operators. In the past, such missions were mainly carried out by manned patrol aircraft and helicopters.
