A tilt-rotor type of unmanned aerial vehicle (UAV)

South Korea will develop an unmanned tiltrotor capable of searching for marine life for deep fishing vessels to replace outdated helicopters and improve safety for pilots, the Ministry of Trade, Industry and Energy said Thursday.
The ministry plans to make a prototype by 2016 and produce a tiltrotor by 2023, which can take off and land vertically from a large fishing vessel to conduct preliminary searches above the ocean.
