Re: Japan Maritime Self-Defense Force
Submarine KUROSHIO was with the DDH KAGA and other DDs cruising thru the South China Sea; seems the Chinese Communist Party wasn't pleased, per other reports I've read......... DFO
"Japan dispatches submarine Kuroshio to South China Sea ASW drill
A Japanese Oyashio-class submarine joined a number of other JMSDF units for an anti-submarine warfare (ASW) drill in the South China Sea last week.
This is reportedly the first time that Japan’s defense ministry has confirmed the participation of a submarine in a drill in the disputed South China Sea region.
According to the defense ministry, diesel-electric submarine JS Kuroshio (SS-596) joined helicopter carrier JS Kaga and destroyers JS Inazuma and JS Suzutsuki on September 13 for an ASW exercise.
Defense minister Itsunori Onodera noted that the exercise was “not directed or targeted at any country”, adding that several exercises involving submarines in the South China Sea took place in the past 15 years.
Commenting on the event, China’s foreign ministry spokesman Geng Shuang said the situation in the South China Sea had stabilized and taken on a good trend. “We urge the relevant non-regional country to respect the efforts made by the regional countries to peacefully resolve the South China Sea issue through dialogue, act cautiously and refrain from doing anything that will undermine regional peace and stability,” Shuang said at a regular press conference on September 17.
After wrapping up the South China Sea drills, JS Kuroshio headed to Vietnam, arriving at Cam Ranh on September 17 for a five-day goodwill visit."

FYI: check out latest Chinese port moves in Sri Lanka and Mideast/Africa. They want the world under their thumb, IMO. The PLAN is now (total # combat ships) the LARGEST in the world.......and climbing. DFO

Re: Japan Maritime Self-Defense Force
The latest JMSDF sub, quoted from
"Japan's silent submarines extend range with new batteries
Mitsubishi debuts homegrown tech as Trump pressures country to buy American

TOKYO -- Japan's first submarine powered by lithium-ion batteries was launched on Thursday, symbolizing domestic defense contractors' hopes that innovations can allow the industry to survive amid renewed pressure from Washington to procure more American military gear.
The 84-meter Oryu was lowered into the water at the Kobe shipyard of Mitsubishi Heavy Industries, the vessel's developer, after being christened with a bottle of sake. The submarine can reach speeds of roughly 20 knots and displaces 2,950 tons. It will be delivered to the Japan Maritime Self-Defense Force in March 2020.
The Oryu is the eleventh submarine based on the Soryu's design. Soryu-class vessels, which started being built in 2005, are among the largest diesel-electric submarines in the world.
But the Oryu is a vastly updated version of the Soryu, the biggest change being the replacement of lead-acid batteries with lithium-ion ones. Mitsubishi Heavy tapped GS Yuasa to supply the high-performance batteries, which store about double the power.
Submarine batteries are recharged by the energy generated by Oryu's diesel engines. The vessel switches to batteries during operations and actual combat in order to silence the engines and become harder to detect. The lithium-ion batteries radically extend the sub's range and time it can spend underwater.
But amid the joyous occasion of the Oryu's launch, Mitsubishi Heavy executives maintained grim expressions. Washington has been pressuring Tokyo to expand procurement of American military gear as a means of cutting the countries' trade imbalance. Such a development would leave Japanese defense contractors with fewer orders.
U.S. President Donald Trump urged Japanese Prime Minister Shinzo Abe to buy more American weapons during a bilateral summit last week. "It is important for us to continue to introduce sophisticated equipment, including American equipment, so that Japan's defense capability can be strengthened," Abe reportedly told Trump.
In recent years, Japan has been ramping up procurement of U.S. equipment, such as the Aegis Ashore missile shield. Up through fiscal 2011, Tokyo's purchases through Washington's Foreign Military Sales program had been less than 100 billion yen ($879 million) a year. That surpassed 400 billion yen this fiscal year.
While these purchases allow Japan to get its hands on high-performance American military hardware, the benefits to the domestic defense industry have been few and far between. Meanwhile, exports of Japanese military equipment have stalled. The Abe government had sought to have Australia order Soryu-class submarines, built by Mitsubishi Heavy and Kawasaki Heavy Industries, but Canberra opted in 2016 to purchase French-made vessels instead. Kawasaki Heavy has yet to export any of its P-1 military patrol aircraft. Plans to domestically develop a successor to the aging fleet of F-2 fighter jets are under a cloud.
But when it comes to military vessels, Japan possesses specialized technology supported by a robust shipbuilding infrastructure. Japan's commercial shipbuilding industry is being squeezed by Chinese and South Korean rivals, and Japan's defense industry is under attack by U.S. military imports. The only domain left for Japan's heavy industry is submarines. The Oryu will be the last of the Soryu class. For the next generation, the Oryu's advanced technology is expected to be repurposed into a 3,000-ton submarine."
Sounds like a VERY capable D/E submarine, hope the batteries work better than in some laptops!! DFO

Re: Japan Maritime Self-Defense Force
I wish them all the luck in the world with this venture on two points , ONE... the apparent successful development of these batteries which apart from the power capability which sound good BUT what most fail to realise is........... TWO the weight saving ......roughly HALF the weight and HALF the size of traditional lead acid type ......which gives the IJN a huge advantage should they be proved stable in use, and screws all the "Weight" calculations which all base their adversaries equipment loadings in the vessel on and redundant space for other bits of kit offered by the weight savings......
God...... I bet the USA /Russian governments are itching to get their collective hands on this technology thats been brewing for years
As far as the IJN are concerned I bet they will be quite nervous of " accidents " and collisions at sea

Re: Japan Maritime Self-Defense Force
The current KAGA has deployed with a DDG escort to SE Asia. She has a Museum on board and one of the display cases is shown here. Note her size (models) compared to the WW2 cv KAGA, built on a TOSA class battleship hull.
I wonder what that book is? Sure not a photo I have in any of mine... Ever seen it Don? New to me! DFO
