XP-1 design and avionics
The forward fuselages and horizontal tails are of a robust, lightweight and cost-effective composite material made from carbon fibres. The wing-body fairings for the P-X are supplied by NIPPI Corporation. The fairings reduce drag by overlaying the joint between the main wing and fuselage. The aircraft carries up to 13 crew members.
XP-1 has a length of 38m, wingspan of 35.4m and a tail height of 12.1m. The maximum take-off weight of the aircraft is 79.7t. The latest technologies provide the XP-1 with higher speed, greater range and useful load than the P-3C aircraft.
The aircraft incorporates the fly-by-light (FBL) system which offers increased resistance to high electromagnetic interference (EMI). The FBL system uses fibre optics to transfer flight control commands at higher speeds.
Hardpoint: 8 wing stations in total (2x on each wing and 2x on each wing root) and eight internal bomb bay stations
- Bombs: 20,000+ lb (9,000+ kg)
- Missiles: AGM-84 Harpoon, ASM-1C, AGM-65 Maverick, AAM-4 (Japanese missile)
- Sonobuoys: 30+ Pre-loaded, 70+ Deployable from inside
- Other: MK-46 and Type 97 and new(G-RX5) torpedoes, mines, depth charges
- Radar: Toshiba, Active Electronically Scanned Array radar system
- Sonar: NEC, multi-static sound navigation system sound
- Anti-submarine systems:SHINKO ELECTRIC CO.LTD., Advanced combat direction system
- Other: Mitsubishi, Electronic countermeasures (CMD, RWR, MWS, ESM)
The P-1 will also be fitted with an artificial intelligence system to support TACCO mission. The advanced onboard combat direction system provides the TACCO operator with the best flight path to attack a submarine. The aircraft can be integrated with radar warning receiver, missile warning system, electronic support measures and countermeasures dispensing systems.
The XP-1 is powered by four F7-10 turbofan engines of Ishikawajima-Harima Heavy Industries. Mounted below the low-set wings, each engine generates a thrust of 60kN.
The high bypass ratio turbofan engine achieves low fuel consumption and low noise levels. The engine has an inlet diameter of about 1.4m and length of about 2.7m. The power plant provides greater flight range and maximum cruise speed to the aircraft.
- Type: Turbofan
