Japan unveils new antisubmarine patrol planes

TOKYO, March 26 (Xinhua) -- Japan's Maritime Self-Defense Force (JMSDF) received the first two of a fleet of next generation P-1 antisubmarine patrol aircraft on Tuesday, with the planes scheduled to be deployed at Atsugi Air Base in Kanagawa Prefecture later this month, local media reported.
The official delivery ceremony held earlier in the day in Gifu Prefecture, central Japan, heralds the beginning of the JMSDF's plans to acquire seven of the high-tech planes to be deployed by March 2014 and a total of 70 P-1s in the long-run, officials said.
The P-1s, designed by Kawasaki Heavy Industries Ltd. in cooperation with the Defense Ministry, will replace the current over 80 aging P-3 Orion patrol planes used by the JMSDF.
The new planes will undergo two years of operation flight testing, before being fully deployed on patrol duties, officials said.
The P-1 development started in 2001 and planed to finish in March 2012. The process was delayed for one year due to cracks found in its wings and bodies.
I’m surprised they didn’t stick with turbo-props.
Well we know what they did with the front 12 feet of the Orions.
Heh.
It's not like they have a long flight to get on station...
Has an excellent golf course.
Obama should try it out. /sarc
“I’m surprised they didn’t stick with turbo-props.”
Me too. How do they loiter? I see the spoiler on the hull but I don’t know enough to tell if that is for patrolling or not. My last ASW experience was P2’s.
Well, now that I’ve looked closer that looks like a flare dispenser. Beats me.
The crows at Atsugi golf course steal golf balls......
Obama crows.
Is there a FReeper out there currently involved in ASW?
The US has developed very unusual sensors, that resemble torpedoes, yet have very low energy consumption. They use the difference in water temperature between the surface and the depths to propel them in a giant sine wave motion for as long as a month without refueling.
The scientific version are called “Argo floats”.
When they break the surface, they send a burst transmission of the data they have collected to a satellite, then they sink again. They are used in large groups to cover a very large area.
With some modification I would hazard to guess that they could passively locate submarines, then send a report of their location, direction, and speed. This would make asub operations a snap.
I was with VP-1 as an avionics tech. The new P-8 has a lot of faults that I can see, no MAD detection, very important when trying to detect something below the thermocline. Airspeed is an issue with sonobouy deployment. The T-56 turboprop’s are more fuel efficient plus it can fly for a long time at low altitude by shutting off 2 of the 4 engines. SAR missions are pretty much cut out due to the P-8’s stall speed they will not be able to drop survival equipment and trying to locate a small craft in trouble at that speed will be almost impossible. For instance one SAR mission we spent hours searching the sea for a 30 foot fishing vessel, it was a small miracle to find an object that small in that large of an area.
This Japanese bird looks like it addresses some of these issues except the turbofan engines.
Four engines: Shut two down, have one turning slowly, use the other for power.
