Given China's behaviour in the South China Sea I'd half expect Japan to tell them to "jog on"

Japan has announced plans for the mass production shortly of the XASM3 aircraft launched anti shipping supersonic missile at 900 kilos with a 150 kilometre range range it would match other regional navies navies who have introduced similar missile capabilities

[ArmChairCivvy]

Add to the above

Defense minister confirmed to purchase of JSM from Norway. LRASM and JASSM-ER will be purchased after further upgrade of F-15J 改 fleets.

and the expectation of some action on the seas seems to have gained in probability
- the disputed islands are more like rocks, so "no" fighting on them then

Fools. Why didn't they ask the RN do they need ASMs...

Japan is on track to deliver fleet of 22 attack submarines by early 2020s

Seven of the their earlier Oyashio class 82m 2,800T surface displacement received major refits to “almost the same level of that of the latest model submarine” (Souryu class, surface diaplacement 2,900T/submerged 4,200T).

In early 2020s UK will end up with 7 Astute class attack submarines (Triumph the last Trafalgar class submarines to be decommissioned in 2022), numbers verse capability, can make a case for either option.

On Feb 21, Japan MoD & UK MoD agree to joint cooperate in the evaluation and certification process of jet engines.

Looks like IHI XF9-1 engine may be tested in the Rolls-Royce's facility.

JMSDF Commissions its First 25DD-class Asahi ASW Destroyer

NBC Nagasaki reports that the latest 25DD class anti-submarine destroyer, the JS Asahi, was officially delivered to the Japan Maritime Self-Defense Forces (JMSDF) at Mitsubishi Heavy Industries’ Nagasaki shipyard. Yutaka Murakawa, the JMSDF chief of staff, led the commissioning ceremony in front of the ship’s 220 crew members and other JMSDF officials.

JMSDF Commissioned its 9th Soryu-class SSK SS-509 JS Seiryu

The Japan Maritime Self-Defense Force (JMSDF) commissioned its 9th Soryu-class diesel-electric attack submarine (SSK) in Kobe in Hyogo Prefecture on March 12, 2018. JS Seiryu (SS-509) joins the JMSDF’s Submarine Flotilla 2, based in Yokosuka.

Soryu class are quite smart looking boats.

[Lord Jim]

They are also probably the most effective SSKs out there.

[R686]

They are also probably the most effective SSKs out there.

And would have been the least risk to the RAN had a modified Soryu got up, still not happy the French got up with the most risk adverse design.

[Lord Jim]

Isn't the Soryu the class the Japanese are looking to install a shed load of lithium batteries in as an alternative to AIP?

Japan's Liberal Demcratic Party (LDP) are allegedly proposing a "defensive aircraft carrier" and obtaining F-35B aircraft to the Japanese government in May.

Conclusion of agreement on collaborative research on the feasibility of next-generation RF sensor system between Ministry of Defense and UK Ministry of Defense

Heisei 30(2018) March 23rd

On 22nd, the Ministry of Defense and the Department of Defense of the UK signed an agreement on joint research on the feasibility of next-generation RF (Radio Frequency) sensor system.

This collaborative research is to examine the feasibility of the radio wave sensor system which the Ministry of Defense and the UK Ministry of Defense jointly can search a wider range instantaneously using radio waves of a wider frequency band. Based on the results of this collaborative research, it is expected that efficient research using the technologies possessed by both sides will be possible through subsequent collaborative research including prototyping.

nice info ares , but when are they going to announce that japan is going to build qe class carrier derivative

[SKB]

Japan honestly have no need to build any further new carriers. They have two Izumo and two Hyūga class ships. The four "helicopter destroyers" that they already have could be adapted to F-35B. The Izumo class is the larger of the two classes and measures 248m long, with the Hyūga class at 197m long.

Skijump ramps and flightdeck heat proofing are something that the UK could assist with, or which Japan could solve on their own. They may not even want to use ramps and fly F-35B in the same manner the USMC does with the Wasp class ships.

Izumo class: https://en.wikipedia.org/wiki/Izumo-cla ... _destroyer
Hyūga class: https://en.wikipedia.org/wiki/Hy%C5%ABg ... _destroyer

[Ares]

Our country's ruling party(LDP) recently suggested to the government to build new 'multi-purpose defensive aircraft carrier' alongside with renovation of Izumo and Hyuga class helicopter destroyers.

http://www.sankei.com/politics/news/180 ... 18-n1.html

I don't think this will be equivalent to QE class but indeed hope to get a similar one in my lifetime.

[Lord Jim]

Next Japan will build a Multi Role Defensive "Stealth" Bomber, and Defensive cruise or ballistic missiles capable of hitting North Korea and parts of both China and Russia. The sooner they come out of the closet and remove "Defence" from the title of their armed forces the better, and it would send a very strong signal to their neighbours.

Great ships though as are all of them.

Two comments.

1: Options we see

スクリーンショット 2018-04-14 11.30.35.jpg

Looks like the default will be 8 Mk41 VLS, and the design around the helo hangar can be changed.

2: Frigate for JMSDF, for the first time. (actually second time)

There is leak (or rumor = not official yet) in Japan, that these ships will be designated "FFM", "Frigate + Mine hunting". If true, this is the first time (*1) using the name of "frigate" for ships built for JMSDF.

Actually the ex-US Tacoma class frigates was designated PF, in 1953-1972.

[ArmChairCivvy]

these ships will be designated "FFM", "Frigate + Mine hunting"

Good thinking spreads fast?
- I exclude the LCS with "modules" from this narrative
