The Kawasaki XP-1 (previously P-X) is a Japanese aircraft design intended as a replacement for the P-3C maritime patrol aircraft operated by the Japan Maritime Self-Defense Force.

[edit] Development
With it s P-3C aircraft having been in service for twenty years, the JMSDF began to look for a replacement maritime patrol aircraft. Lockheed and the United States had been working on the Lockheed P-7 to replace its own P-3s, but the program had been cancelled. Since other similar aircraft (such as the Nimrod) did not meet the JMSDF's requirements, they decided to develop their own aircraft.
The project was intended to share many design components with the Kawasaki C-X, another local design intended to replace the C-1 and C-130H cargo aircraft. However, due to the very different roles of the two aircraft, only minimal similarities have been achieved. The merit rather lies in the sharing of development resources, allowing a large reduction in development costs. Total development costs included C-X are 345 billion Yen ($3 billion) at 2007.[1]
[edit] Design
Like the Nimrod and S-3 Viking, the P-1 is a turbofan design. The XP-1 is powered by four small turbofan engines, the Ishikawajima-Harima Heavy Industries F7-10 in development, mounted under the low-set wings.
The P-X and C-X designs were originally independent, but it was later decided to make certain components common to both designs.[2] Common components shared with the C-X are cockpit windows, outer wing, and horizontal stabilizer. Other internal shared parts include auxiliary power unit, cockpit panel, flight control system computer, anti collision light, and gear control unit. Development costs decreased by about 25 billion yen ($218 million) due to shared components.[citation needed] Unit costs and operational costs are expected to be lower thanks to this initiative.
The P-1 will also have an artificial intelligence (AI) system to assist TACCO operation. Similar to the SH-60K, an advanced combat direction system able to show the TACCO operator the best flight course to attack a submarine will also be onboard.[3]
Fly-by-light will be an important feature, decreasing electro-magnetic disturbances to the sensors compared to fly-by-wire. The P-1 will be the first production aircraft to be equipped with such a flight control system.
Sensors on the P-1 will be used to detect submarines and small vessels, such as phased array radar, magnetic anomaly detector (MAD), and Infrared/Light detection systems. The aircraft will share operational capabilities with the P-8, with some sensors being the same(i.e. CAE-designed MAD system). [4]
The P-1 will have a bomb bay for anti-submarine weapons, as well as eight external pylons[5] to carry ASMs or bombs.[6]
[edit] Operational history
A test article airframe was delivered[when?] to the Japanese Defence Agency for static load testing, with deliveries slated for 2010.
On August 31, 2007 the Ministry of Defense revealed that they will procure four production airframes. The request in the Heisei20 (FY2008) budget is 67.9 billion YEN, or about 566 million US dollars. This will make the unit price for each aircraft at $141.5 million[7].
The XP-1's first flight took place in Gifu Air Base in Japan on 28 September 2007. The flight took about one hour, and ended successfully.[8] The P-X was redesignated as XP-1 at this time.
