  JS Tenryū (ATS-4203) is a training support ship of Japan Maritime Self-Defense Force.
  
  ## Development and design
  
  It is a ship for anti-aircraft shooting training support, and its main purpose is to launch and guide unmanned target aircraft. It was built as a complement to the air threat, higher performance of air defense weapons, and the obsolescence of the predecessor training ship JDS Azuma.
  
  It is a flat deck type ship type, equipped with one 76-millimetre (3.0 in) single gun on the front deck. The target aircraft will be equipped with four BQM-74E Chaka III. These target aircraft are launched from the rear helipad, and up to three aircraft can be simultaneously guided and controlled by a four-sided phased array radar on the top of the ship's structure. A radar for evaluating shooting results is also installed separately.
