A fully-fledged land-based anti-submarine patrol aircraft developed from the 17th experimental patrol aircraft.
Although it is slow, it is equipped with the newly developed "KMX" magnetic anomaly detector that makes it specialized for submarine hunting.
It is expected to play an important role as a land-based anti-submarine force.


Land-based Patrol Aircraft Land-Based Patrol Aircraft are counted as regular Land-Based Attackers on every aspect. Land-Based AttackersLand Based Attack AircraftLand-based FighterbomberLand Based Assault AircraftLand-based Patrol Aircraft are the main type of bomber used on LBAS. Their most important stats are "torpedo" Torpedo Attack against regular ship, and "dive bombing" Dive Bomber Attack against Installations, as well as their "combat radius" Operation Radius.

Additionally, Patrol Aircraft are ASW Aircraft, and so are mainly used for ASW (see here).


Not to be confused with other aircraft of this family (see here).
