P-X (P-1)
Kawasaki · Japan · first flew 2007 · bomber
The Kawasaki P-X, in service as the P-1, is a Japanese long-range maritime patrol aircraft and one of the few clean-sheet jet designs built specifically for the role.
Recognition (WEFT)
| W — Wings | Low-mounted, swept |
|---|---|
| E — Engines | 4 × turbofan, wing-mounted |
| F — Fuselage | Airliner-like fuselage with tail MAD boom |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Purpose-built maritime patrol jet
- Four underwing turbofans
- Airliner-like fuselage with tail MAD boom
Look for an airliner-sized jet with a low swept wing carrying four engines, a slender fuselage and a magnetic-anomaly boom projecting from the tail.
Specifications
- The P-X (P-1) has a length of 38 m (125 ft).
- It has a wingspan of 35.4 m (116 ft).
- Its maximum speed is 996 km/h (619 mph).
- Typical crew: 11.

History
Developed together with the C-X transport, the P-X first flew in 2007 as a replacement for the Lockheed P-3C Orion. It is unusual in using four home-built IHI F7 turbofans rather than the two engines typical of modern patrol jets.
Variants
The programme has focused on the single P-1 patrol version, though the airframe has been proposed for other special-mission fits. Its four-engine layout is intended for reliability and low-speed loiter over the sea.
Where you'll see it
It serves the Japan Maritime Self-Defense Force; the RAF's equivalent submarine-hunting role is filled by the twin-engined Boeing P-8 Poseidon.
