The Kawasaki P-2J—initially designated as the P2V-Kai—served as a maritime patrol and anti-submarine warfare (ASW) aircraft specifically engineered for the Japan Maritime Self-Defense Force. It represents a twin-turboprop adaptation of the original radial-engine P-2 Neptune, developed to offer a more economical solution compared to the larger and costlier P-3 Orion, which ultimately replaced it during the 1980s.
Design and development
The P-2J, produced by Kawasaki and known as P2V-Kai (with "Kai" (改) signifying modification), was the concluding variant of the Neptune series. Its development commenced in 1961. The prototype, converted from a P2V-7 (also called P-2H), completed its maiden flight on 21 July 1966. By March 1979, a total of 82 units had been manufactured.
In this model, the original Wright radial engines were substituted with two Ishikawajima-Harima T64-IHI-10 turboprop engines, each delivering 2,125 kW (2,850 HP) and equipped with three-bladed propellers. Additionally, booster turbojets—specifically Ishikawajima-Harima J3-IHI-7C engines generating 13.7 kN (3,085 lbf) of thrust—were installed, allowing the aircraft to achieve higher speeds.
The aircraft's crew capacity reached up to 12 personnel. Notable structural modifications included an extended forward fuselage and enlarged, redesigned tail surfaces. It incorporated an AN/APS-80 search radar housed within a reduced-size radome along with modernized, compact avionics systems that enabled increased fuel storage. The landing gear was also improved, featuring twin wheels on each main gear leg instead of single large wheels.
Operational history
Throughout the 1980s, the P-2J was gradually retired in favor of the P-3C Orion,[1] which became prevalent among Western maritime patrol forces. The last squadron dedicated to maritime reconnaissance transitioned fully to the Orion platform by 1993. Nevertheless, the P-2J remained operational in roles such as electronic reconnaissance and target support until it was fully withdrawn from service.
Variants

- Initially known as the P2V-Kai, equipped with T64 turboprop engines and IHI J3 engine pods; featured upgraded ASW and ECM capabilities, APS-80 radar, and expanded fuel tanks; one unit converted from a P-2H and 82 newly constructed.
- EP-2J
- Electronic intelligence (ELINT) version derived from the P-2J; two units converted.
- UP-2J
- Modified for drone operations, target towing, and experimental purposes; four units converted.
