Japan's shipbuilder Kawasaki Heavy Industries (KHI) launched the 12th and final Soryu-class diesel-electric attack submarine (SSK) for the Japan Maritime Self-Defense Force (JMSDF). JS Tōryū (とうりゅう) SS-512 is the second submarine of the class to feature Li-Ion batteries.
The launching ceremony was held today at the KHI shipyard in Chuo-ku, Kobe. About 380 people from Japan’s Ministry of Defense and KHI participated in the ceremony. As per tradition, Admiral Hiroshi Yamamura, Chief of Staff of the JMSDF, cut the rope which started the launch process and send the new submarine in the water for the first time.
JS Toryu is the 12th and final Soryu-class submarine produced for the JMSDF (the 6th built by Kawasaki Heavy Industries, the other 6 having been built by Mitsubishi Heavy Industries). Tōryū (とうりゅう) means Fighting Dragon. The name of Toryu is derived from the famous scenic dragon fighting in Kato City, Hyogo Prefecture, where the torrent of the Kako River flows between strangely shaped rocks.
SS-512’s keel was laid in January 2017, and the submarine is set to be delivered to the JMSDF around March 2021.

The keel for the first submarine in the class, Soryu (SS-501), was laid down in March 2005. It was launched in December 2007 and commissioned in March 2009. The latest Soryu class SSK to joint the fleet isSS-510 JS Shōryū which was commissioned on March 18, 2019.
Twelve Soryu-class submarines are currently planned for the JMSDF. The design features improved underwater endurance thanks to lithium-ion batteries from the eleventh submarine in the class. Previous submarines use Lead-acid batteries. Designed by GS Yuasa, the high-performance Li-Ion batteries are said to store about double the power. The last two submarines of the class, fitted with the new battery technology, will probably serve as test-bed for the next generation of Japanese SSK.
The Soyu-class is an improved version of the Oyashio-class submarine. Soryu-class submarines are the world’s largest conventionally powered submarines. All submarines of the class are named after dragons: Soryū means Blue Dragon, Hakuryū (2nd in the class) White Dragon, Sekiryū (8th in the class) Red Dragon, Shoryu (10th in the class) means Soaring Dragon…

https://www.reuters.com/article/us-usa- ... SKBN24A3F3U.S. State Department OKs possible $23 billion sale of F-35s to Japan
(Reuters) - The U.S. State Department said on Thursday it had approved the possible sale of 105 Lockheed Martin (LMT.N) F-35 fighter jets to Japan at an estimated cost of $23 billion.
The Japanese request included 63 F-35A and 42 F-35B aircraft, 110 Pratt and Whitney RTX.N F135 engines, and related equipment, it said, and implementation of the proposed sale, including technical support and training, would take 25 years.
"It is vital to U.S. national interest to assist Japan in developing and maintaining a strong and effective self-defense capability," the State Department said, adding that the proposed sale would not change the military balance in the region
F-35 jets are made at a Lockheed Martin factory in Fort Worth, Texas, but allies assemble jets for themselves at two final assembly and check out facilities in Japan and Italy.
In March, the Pentagon said Mitsubishi Heavy Industries (7011.T) was closing the Japanese plant for one week due to concerns about the coronavirus.
Le Japon va moderniser ses F-15 !
Je vous en parlais en octobre 2019, le Japon prépare une imposante modernisation de sa flotte d’avions de combat Boeing F-15J. Cette modernisation va débuter prochainement avec le partenariat entre Boeing et Mitsubishi Heavy Industries (MHI) pour les mises à niveau. L’occasion d’en savoir un peu plus sur ce projet particulièrement pointu. Au total se sont 98 appareils qui sont concernés par cette modernisation.
F-15J « Japan Super Interceptor » (JSI) :
C’est sous cette dénomination, que le projet de 4,5 milliards de dollars va débuter avec les mises à niveau qui introduiront une nouvelle capacité de guerre électronique et des armes de pointe. Un tout nouveau système de cockpit avancé, fonctionnant sur l’ordinateur de mission le plus avancé au monde, offrira aux pilotes une meilleure connaissance de la situation.
En vertu de cet accord, Boeing fournira à MHI des plans de modernisation, des équipements de soutien au sol et des publications techniques pour la mise à niveau des deux premiers avions F-15J vers la configuration « Japan Super Interceptor ».
Le programme comprend : l’installation du radar AESA Raytheon AN/APG-82 (V) 1, du système de guerre électronique numérique Digital Electronic Warfare System (DEWS) AN/ALQ-239 de BAE Systems. Des ordinateurs de système de mission Advanced Display Core Processor II (ADCP II), un système de planification conjointe des missions (JMPS) avec logiciel, formation et soutien est également inclus, module anti-spoofing à disponibilité sélective (SAASM). Intégration de radio, d'aéronefs et de munitions ARC-210 et soutien aux essais, dispositifs de formation au sol (y compris simulateurs de vol et de maintenance), équipement de support et d'essai, livraison de logiciels et assistance, pièces de rechange et de réparation, matériel de communication, installations et soutien à la construction.
Rappel :
Vers le début du siècle, les F-15J ont été mis à niveau localement avec un radar Raytheon AN/APG-63 (V) 1, des moteurs F100-IHI-200E et de nouveaux sièges éjectables, ainsi que certifiés pour transporter le missile AAM-4 domestique air-air à moyenne portée. Plus tard, en 2009, certains ont reçu des mises à niveau avec la liaison de données Link16 et les viseurs de casque pour le missile à courte portée AAM-5 (Type-04).
Les 98 F-15 qui seront mis à niveau vers la configuration JSI sont ceux qui ont été initialement livrés avec les modifications du programme d'amélioration en plusieurs étapes (MSIP). Les avions non-MSIP devraient être progressivement abandonnés et remplacés par des F-35.

http://alert5.com/2020/08/08/japan-unve ... df-f-35bs/Japan unveils plan to develop Mage Island into FCLP for CVW 5 and JSDF F-35Bs
The Japanese government has unveiled its plan on how to develop Mage Island, off Kagoshima Prefecture, into a Field Carrier Landing Practice (FCLP) facility for Carrier Air Wing 5 (CVW 5) of the U.S. Navy and Japanese F-35Bs Tokyo will pay $151 million to the owner of the island and an environment impact assessment will be carried out this fall.
There will be two runways, a hangar, and a fuel facility at the base. The main runway is about 8,00 feet long, and the secondary is about 6,000 feet long. About 150 to 200 Self Defense Force personnel are to be stationed there. Construction will take 4 years.
The base will be resupplied by JGSDF MV-22s.
Currently, U.S. Navy pilots practise simulated aircraft carrier landings at the FCLP at Iwo Jima, which is 1,400km from their base in MCAS Iwakuni.
The new FCLP at Mage will be cut the distance down to 400km.
