Kawasaki XP-1

Thu Dec 11, 2008 7:10 pm

Hi all,

I noticed the first photo in the a.net db of this aircraft this morning and was stunned to see what almost appears to be a Convair 880 look-alike. I'd never heard of this aircraft until I saw the photo. Does the P-1 appear to have a successful future? Might it win some export orders? Does anyone have more photos?

I am not sure if they are allowed to export these aircraft as they were developed at a home grown replacement for the P-3, and the Japanese constitution forbids the sale of military equiptment to foreign countries. This aircraft was also developed in tandem with the C-X, a Kawasaki C-130 replacement.

Designed as a replacement for Japanese P-3 Orion's, (themselves built under license in Japan), this rather unique aircraft is most unusual for a maritime patrol aircraft of recent decades, in that it's not a converted civil or other military airframe.

Japan is also building a twin CF-6 powered military transport, this high winged cargo hauler is to share many components with the XP-1, not that this is immediately obvious externally.

Not the first time that Japan has done something different in the MPA field, in the 50's they had a large force of P-2 Neptunes.
While most other users replaced them with P-3's, Japan built a further uniquely modernized P-2 version, with turboprops replacing the piston engines of the Neptunes.
This version actually remained in production until the late 70's, long after most other regular Neptunes worldwide had been replaced.

Then in the 70's Japan produced a new 4 turboprop large flying boat, in both anti sub and search and rescue versions, long after flying boats in military service had gone from the rest of the world.
The ASW flying boats have left service, but the SAR ones remain and a new, modernized version is in production.

Export prospects for XP-1, and any other military product by Japan, is very seriously limited by it's defensive post WW2 constitution, which prohibits virtually all military exports.
From tanks to jet trainers, it's all not for export sale.
The motivation for this is in part, despite these limitations, is to keep a competent capability for military and aerospace technology, beyond license building mostly US types.

Japan has had very limited success with aerospace exports, in stark contrast to virtually every other industrial field.
But they want to retain the ability, be it by their own space launch vehicles or aircraft.
With the recent launch of the Mitsubishi Regional Jet, the first airliner from japan since the moderate selling YS-11 turboprop of the 1960's, their reasoning here becomes apparent.
They want to stay in the game.
This seemingly eccentric looking XP-1 maritime aircraft is a part of that.

This little thing could also become a regional Jet. What are your thoughts on that?

Maybe too many engines and too much weight for a RJ, or any other airliner.
Besides, they are building the MRJ.

A very interesting aircraft.
Unusual to have a four jet engines Patrol aircraft (apart from the Nimrod)
The wing resembles that of an A340 and the engines seem to be those of the Embraer170
It actually looks a bit like a quad E-170.
Which engines are those? CF34?

Can´t wait to see the C-X flying but I´ve read somewhere that it´s behind schedule and with some serious problems to be solved.
It will look like a smaller 2 engined C-17  Smile

They are Japanese engines, IHI XF-7, specifically for this airframe it seems.

Two new projects with one new engine type (the C-X is meant to have GE CF6, right?)

I wonder if they'll shut down two engines when they reach their patrol area? Don't know if the P-3's did that or not. Can someone who knows please correct me?

Also, what a beautiful looking aircraft!

I don't know about P-3's, but it is practice for Nimrods to transit at high speed to a patrol area, then shutting down two engines to increase endurance (and offset the higher fuel consumption of a jet compared to a turboprop MPA).
I'd expect the XP-1, once in service, to do the same.

P-3s shut down one engine. Usually one of the outboards.

The P-1 doesn't look like a heavy, but these are not small aircraft. alert 

The F-7 engine is rated at 13,500 lb, putting the P-1 in the same weight class as the Nimrod or the P-8 Poseidon or indeed, the Convair 880 (about 85 tonnes - 180,000-200,000 lb).

So an 'RJ' version would actually be a 757-sized airliner!

And the C-X, at 141 tonnes (310,852 lb) MTOW, is in the same class as the A400M!

Quoting GDB (Reply 2):
share many components

Well, some systems probably. The P-1 and C-1 are obviously very different aircraft.

All in all, a strange effort by the Japanese I think... why not concentrate on a dedicated airliner first, which you can export, and then derive a patrol aircraft from it?

I read that in Japan, completely unneccessary infrastructural works such as the casting in concrete of riverbeds are often carried out to keep builders and voters happy... I wonder if this project is an example of that.

When I first saw the picture I thought someone had slapped jet engines on a P-3. (similar to the Dornier 328J)

This is a good looking aircraft.

Not quite. The C-X is the replacement for the Kawasaki C-1.

Quoting Oroka (Reply 1):

I have mentioned in a previous thread that I made about these two aircraft that this is actually a common misconception. The restriction of arms exports has nothing to do with the constitution of Japan. It is actually the result of a series of policy decisions in the 60's and 70's.

Quoting GDB (Reply 4):

Not sure really how much I should say about it but, as you state, a quad regional jet would clearly never get anywhere in today's world. I can tell you now that as well as other changes, a KHI regional jet would Not have four engines. Also, it would Not be in direct competition with the MRJ which is produced by MHI. Though whether or not they will actually go ahead with this project is yet to be decided.

GDB hit the nail on the head here. During the development of these aircraft, there were even regulations governing who could participate in the project. No engineers above a certain age limit could be involved. This even extended down to the first tier sub-contractors.

Is the 4- engine configuration intended to provide redundancy for extended overwater operations or is there some other reason?

Sure looks cool, regardless.

I just watched the videos.
The XP-1 is so cute  Smile
Looks so tiny but actually is as big as a P-3.

The C-X really IS a C-17 with two engines.
The front fuselage, the tail arrangement and, at a lesser extent, the wings are all very similar to the american cargo plane.
Those CF6 engines looks massive.

Great job, Japan. Too bad they won´t be available for export.

The Japanese P-X and C-X designs are interesting.


Japan, facing the end-of-life of the C-1 and looking past the P-3 decided that they would construct a domestic replacment program for both using a loose "large aircraft" development program.


Is the P-X Convair-ish? Yes. Is it a commercially viable platform as designed with four engines? No. As one poster above noted, this was one of Japan's notorious public/private programs to foster domestic production of aircraft without a clear marker on any sales afterwards.. Japan simply decided that it was going to design and build its next series of large military aircraft for domestic consurmption purposes hoping it might later adapt those models for sale. Nothing wrong with it, just the facts.

I think there could be an interesting export potential for both models.
Countries like Germany and Italy have been looking to an Atlantic replacement without success. Germany opted to buy former Dutch P-3.
Italy, as usual, decided against deciding, that´s to say, the old Atlantic are still in service.

The C-X could well get some attention from Countries that want a larger platform than the C-130 but cannot afford the C-17 or don´t trust the ability of Airbus to deliver the A400M in time and in cost.

But these two nice birds will never wear any other insignia than the rising sun.
