Pics have emerged of the XP-1 maritime patrol aircraft equipped with Type 91 anti-ship missiles.
The Type 91 anti-ship missile is roughly equivalent to the American Harpoon, and is deployed on JMSDF ships (SSM-1B), planes (ASM-1), and even by the GSDF (Type 88) on land.
XP-1 appears to sport a total of four hard points for missiles.
Type 88.
A rough comparison of Type 91 – class missiles.
| Name | ASM-1 / Type 91 (JPN) | Harpoon (US, JPN) | C-602 / YJ-62 (PRC) |
| Warhead | 270 kg | 221 kg | 300 kg |
| Max. Speed | 1,150 km/h | 864 km/h | Mach .9+ |
| Range | 200 km | 280 km | 400 km |
| Delivery | Air, Surface | Air, Surface, Sub Surface | Air, Surface |
H/T: Alert 5.

I like the look of the new kit but as I think everyone else realizes looking at that thing the absolute best solution for maritime(or any surveillance) is going to be UAV.When I look at that plane the first thing I think is wow that thing costs a lot of money to operate(Fuel,R+D,Personnel) you can have surveilling,more coverage,and more security for less(possibly a lot less)with an armed UAV. This being a new platform they are going to have to get all the use out of they can but hopefully they will not let that get in the way of pursuing UAVs in earnest.The fact that China deployed one on their cruise around the Japanese island of Okinawa doesn't hurt.

The truth is maritime patrol are not just for surveillance and can't be done by UAVs alone especially in actual combat situation since you need to drop sonar buoys to listen in and fire torpedoes if need be. There will always need a people input in what to do next constantly.

I am talking about surveillance not combat.The first rule of surveillance is persistence.A uav is superior in most every category for surveillance vs human driven vehicles that I can think of.The world leader in most military capabilities is the U.S. and if you watch them they are investing heavily in UAV developement.The point I was trying to make is I hope that the fact that Japan is just entering these aircraft in service does not hamper their long term thinking which should include a healthy dose of UAV,UUS, and UGV development.I understand that for certain tasks humans have to be involved but patrol without combat in front of it would denote routine,everyday surveillance. The Japanese have to start looking at cutting costs and personnel any where they can and also I would think it takes a similar amount of people to build a UAV as it does a manned aircraft.

Honestly speaking I think that will be a waste of money since once in combat you'll need an attack plane that has the same sub tracking system as the drone surveillance drone making the drone redundant.
UAVs are good in peace time or asymmetrical warfare where you have a clear technological advantage but the effectiveness becomes very limited when the opponent has the same technological expertise where they can jam radio signal.

If you really look at the US, you would realize, that they are actually replacing their own old P-3s with a new manned platform, the P-8 Poseidon, similar in config to the XP-1 and exactly for the reasons mentioned by the commenters responding to you. UAVs have their place, but so far the clearly defined role of MPAs based on very solid requirements, is not one of them.

I am aware of the replacement MPA's.The U.S has a $600 billion (declared) defense budget,we have more volunteers then we can put in uniform,we have a population that is growing. Japan has none of these.I have never once said that Japan has no need for manned MPA's.What I have said is I hope that Japan will at least look at UAV's as an augmentation or even a replacement for some ,not all,of their manned platforms and not be close minded about new or different platforms just because they have invested so much in these new manned aircraft. I fully understand that Japan will absolutely have to try to get a return on their investment.That should not be an excuse to not look at other platforms long term. I think Japan,with her current issues would be well served with some UAV's.

I agree with Tri-ring. UAVs have a lot of potential, but they're not ready for prime time yet and there are still a lot of missions they simply can't do, or at least, can't do well. Even if the SDF were to develop surveillance UAVs, something I would definitely support, there would still be a need for aircraft like this.

I disagree with your assesment of the usefullness of UAV's.The main point I am trying to make is for the Japanese to not let the fact that they are introducing an expensive,new plane to cloud their collective vision of what will be the best solution moving forward,which is UAV. When a new platform is inducted sometimes the powers that be insist that this is the best way to do things because they have so much invested.They have to justify it,that tends to color one's perspective about what might be best long term.I have never said that piloted aircraft should be replaced wholesale,I actually said that the Japanese will have to get all they can from this craft to justify expenses,but that is all they should try to get out of it and not let it impair their long term thinking.They are a nation that is under sever fiscal strain, with a stagnating economy and a decreasing demographic.These reasons would seem to push Japan towards a less personnel(training and numbers)intensive,less operating cost intensive platform. If you can increase your numbers by decreasing your operating costs then you can be in more places correct?Does that not increase your security and overall ability to respond to threats?The DDH's,the increase in subs and your still existing manned platforms are your response to any threats that crop up but if you are able to monitor more ocean then I think you are better off. If your intention is to be able to monitor more ocean at less cost then UAV's do this better than manned in my opinion.

Kawasaki Heavy Industry held a delivery ceremony to commemorate the delivery of the first mass-production type P-1 to JMSDF at their Gifu factory on the Mar.26,2012.
This will be first of the initial 8 ordered by JMSDF to be delivered by the end of fiscal 2014.
It is speculated 70 planes will be manufactured in total to replace the aging P3C fleet.
