Japan Cannibalizes P-1 Patrol Aircraft, Reportedly Stripping Some New Jets for Parts
Japan's Maritime Self-Defense Force is using grounded Kawasaki P-1 patrol aircraft as parts donors, with some newly delivered airframes reportedly cannibalized immediately to keep other aircraft flying. A Japanese television report put mission-capable availability at 20 to 30 percent, while an official audit confirmed cannibalization, engine corrosion and prolonged spare-parts delays without publishing that readiness rate. Salt exposure during low-altitude maritime operations has affected IHI F7-10 engines, and some replacement components have taken years to arrive. The Defense Ministry aims to address shortages by fiscal 2027 through contracts combining parts, repairs, maintenance and supply.
