Japan will send one of its two Izumo-class helicopter carriers on a two month-long tour of the South China Sea and Indian Ocean for the second straight year as the country aims to bolster international co-operation in safeguarding key sea lanes in the Indo-Pacific region, a Japanese official told Jane’s on 6 June.

Starting in September JS Kaga (DDH 184) will make stops in Southeast Asian countries such as Indonesia and the Philippines and at ports in India and Sri Lanka. The ship will also make a port call at Singapore’s Changi Naval Base at around the same time as the 12th ASEAN Defence Ministers' Meeting (ADMM) and the 5th ADMM-Plus meeting are scheduled to be held there (18-20 October).

“This is part of Japan’s efforts to promote a free and open Indo-Pacific strategy,” the official said. “For maritime security Japan is focusing on capacity building assistance to Southeast Asia and on what we call ‘strategic messaging,’ which appeals to the rule of law for securing free and open seas,” the official added.

The Japan Maritime Self-Defense Force sent out Kaga ’s sister ship, JS Izumo (DDH 183), on a similar tour last year.

I didn't go over it Jura because we have other threads to rehash a debate of the pros vs Cons of F35 and F22 and we have done it over and over and over again.
No matter what I say to you you will continue to be cynical regarding those programs and I will continue to be a proponent. And most of all There is Time.
There was a Time when people laughed off the Raptor now it's excepted. There was a Time when F16 was ridiculed as behind schedule over budget and a mess Now it's a established platform nearing the end of service.
There will be a Time when F35 is accepted.

It doesn't matter if it is accepted in the not for seen future to the government, it's perception of the present that matters and at this point F-35 and to an extent the F-22 is too hot a potato for the JP government to place faith considering how the media and constituents will perceive.
Basically the ship had already sailed.

I still hold out hope that the Izumo carriers, and perhaps a follow on will get F-35Bs.

Time will tell...but Japan is in a GREAT position to be able to produce two immediate (at least in short order) carriers capable of carrying 20 F-35Bs each whenever it wants, and to build two more as well.

...and I hope they will.

Looks as if IHI had delivered the XF9-1 jet engine proto-type to ATLA as promised.

Two XF9-1 engines mounted on the YF-23 will certainly be a sight to see.

Thats a huge develpment. According to that, the thrust with afterburner is roughly 15,000 kgf (147 kN) .That is less than the F119 but importantly the the dry thrust is stated as roughly 11,200 kgf (110 kN). That dry thrust is quite impressive. The AL-41F1S (117S) has a dry trust of around 86 kN. Dry thrust of the AL-41F1 (117) powering the Su-57 can't be much higher than that. F119 dry thrust is said to be around 110 kN. Thats a hell of a leap by Japan. It will probably take many more years (perhaps a decade) for the engine to be fully ready for production but still it is impressive.

The engine isn't in the same size class of the F119 with its 4.8m length and 100cm diameter. It roughly sits between the F119 and the EJ200. It's a clear indicator for the size of the planned stealth fighter.

15t and the 11t written within the attached page is the floor spec. The word 以上written right after means more than so rightfully it means more than 15t and more than 11t.
As for when it will be ready, my guess is around 7 to 8 years when the F-3 proto-type is ready for testing with it's engines.

Which makes it even more impressive! It is 4.8m in length and 1m in diameter (Dry thrust 11+ tons). In contrast, the F119 is 5.16m in length and 1.2m in diameter (Actual thrust values are classified but the Dry thrust is believed to be roughly 11.6t). F135 is 5.56m in length and 1.17m in diameter (Dry thrust 12.7t). So the XF9-1 is smaller in dimensions and for supercruise that dry thrust is key. Like I said, this is one hell of leap by Japan.

I guess Japan not getting the F-22 turned out to be a good thing.
