Kawasaki P-1 is next generation maritime patrol aircraft for Japan Maritime Self-Defence Force.
Development program started 2001 as a replacement for JMSDF's P-3C, first flight at Gifu Air Base on September 28 2007.
P-1 shared development's resource and airframe parts with JASDF's next generation transporter C-2.
This share means decrease development costs, unit costs and operation costs.
P-1 designed ASW aircraft exclusive use airframe and exclusive use four turbofan engine, this design without precedent.
This design aimed securing survivability by high speed and multiple engine, countermeasures for anti air fire.
And new avionics need many weight payload, but turboprop is under power for this demand.
Hawker Nimrod powered four turbofan engine、but Nimrod developed from Dehavilland Comet.
Lockheed P2V Neptune and Breguet Atlantique are exclusive use airframe、but they ware not powered turbofan only.

Engine Specification
Fan Case Diamater:1.4m
Bypass Ratio:8.2

F7-10 is high bypass ratio turbofan engine which developed IHI, designed exclusive use for P-1.
Engine core based low bypass ratio turbofan engine XF5, fan changed large size for high bypass ratio.
Performance about SFC and environment's improvement, material selected strong alloys for salt damage.
APU selected Honeywell's 131-9, mounted forward stabilizer.
This mount position avoids MAD boom and rear radar.
Sonobuoy launcher is multiple tube type like P-3, but tube mass decreased.
And tube size not uniformity、deployable tube change angle.
2 launchers of inner tube are rotary type, other 4 launchers are manual type and last one is free fall type.
Main wing is orthodox stile, installed full span front slat and single fowler flap.
Eights weapon pylon's station under wing, installed BRU-47/A weapon ejector rack which can hang 2000lbs.
Wing area about 170sq m is wider than 737 or A320, wing loading is as like as P-3.
Wide wing area make to increase drag, but P-1 decrease body width to suppresses all airframe's drag.
Wing components shared outer one of three with C-2, edge's ESM sensor and light shared too.
Bomb bay under front body as P-3, launch torpedo and depth charge.
Nose front and side are mounted HPS-106 radar system's antenna, total four AESA installed with rear mounted.
HPS-106 developed by Toshiba and TRDI, refrigerative cooling type X-band active electronically scanned array radar.
And antenna elements use GaN, antenna composed hundred modules that have 16 elements.
Function are multi beam in single module, air target search, multiple array module integration, ISAR and SAR as like as AN/APY-10.
HPS-106's antenna size is very wide, so nose radar doom is large and round shape.
And cockpit windows are large for wide front view, P-1's nose shape are made these factor.
Cockpit windows are shared with C-2.
Fujitsu's FLIR HAQ-2 mounted under nose, mount type as like P-3.
There is active IFF antenna ahead windows, its arrangement under rear body too.
Missile warning sensor mounted nose side, and rear side.
Front over top doom is ESM antenna, rear doom for SATCOM.
Rear fin shape is orthdox, but vertical stabilizer position is forward than normally.
There is radar array mount position、stabilizer's back is GFRP monocoque structure.
End top is MAD boom, there is in Mitsubishi Electric's HSQ-102.
Mitsubishi Electric contracted CAE's AN/ASQ-508(V)'s license, but CAE's MAD was not used.
Horizon stabilizer components shared with C-2.
Flight control system used Fly by Light, FBL is decreases electromagnetic noise.
Almost cockpit panel are shared C-2, difference parts are engine control panel and HUD. P-1 not mouted HUD when mockup, but Shimadzu Corporation commented in JA2008, P-1 mounting HUD as well as C-2.
But P-1 have observer seat and flight engineer seat, C-2 is two man crew system.
TACCO seat and NAV/COM seat positioning back of cockpit block, more after four sensor seat.
Sonobuyo launcher tube arrangement before main hatch, rear side watcher seat and rest seat block.
P-1's TACCO station installed advanced combat direction system(ACDS) HYQ-3, which used artificial intelligence technology.
HYQ-3 analyzes each sensor's signal information, and presents best action for TACCO man.
This system is automation of judgment for decrease workload and reaction time, as like Aegis Command and Decision System.
Basic concept is as like HYQ-2 which installed SH-60K.
Sound system installed HQA-7, whitch controle HAS-107 sonobuoys conected radio antenna, HRQ-1 sonobuoys reception antenna and HQH-106 record player.
P-1's life cycle costs is estimated 1,285 billion yen by Japan Ministry of Defense Equipment Procurement and Construction Office.
Estimate condition is about 70 units and about 20 years operation time, per units costs are about 32.6 billion yen.
Per units and one year costs about 1.6 billion yen, it's almost equal to about 16.29 million dollars which is P-8A's costs in FY04.
All units costs about 892.8 billion yen is 39.1% of total LCC, operation costs 1,089.5 billion yen is 47.7%.
Development costs about 345 billion yen include C-2, P-1's allocation costs are about 186.6 billion yen and 8.2% of LCC without C-2.
Include other test costs 247.4 billion yen, this is 10.8% of LCC.
Technology research costs about 55.3 billion yen are 2.4% of LCC.

Starting point is insinuation for man, say adopt P-8A.
Britten side of the Royal Air Force.
Its not insinuation nor sarcasm, Japanese military community's private joke.
Britten side is kind of sick.
