Dragon-Phoenix

According to Navy Recognition, the 11th Soryu-class submarine, JS Oryu (SS-511), was launched at the Mitsubishi Heavy Industries shipyard in Kobe on October 4th. JS Oryu (SS-511) features one significant design upgrade: It is Japan’s first submarine powered by lithium-ion batteries.

JS Oryu (SS-511) is the 11th Soryu-class submarine built for the Japan Maritime Self-Defense Force (JMSDF): the 6th built by MHI, the other five ones having been built by Kawasaki Shipbuilding Corporation is the shipbuilding subsidiary of Kawasaki Heavy Industries. Oryu’s keel was laid in November 2015 and the submarine is set to be delivered to the JMSDF in March 2020.

The keel for the first submarine in the class, JS 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 JS Seiryu (SS-509) was commissioned with the JMSDF on 12 March 2018.

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) Soar Dragon.

JS Oryu (SS-511) (おうりゅう or 凰龍 in kanji) means Dragon-Phoenix.

Twelve Soryu-class submarines are planned for the JMSDF. The eleventh and twelfth submarines will feature improved underwater endurance thanks to lithium-ion batteries. The class is an improved version of the Oyashio-class submarine. Soryu-class submarines are the world’s largest conventionally powered submarines. They have an excellent operational track record and are equipped with state-of-the art technologies, including Air-Independent Propulsion (AIP) systems that enable them to remain fully submerged for long periods of time, and advanced stealth technologies that make them more difficult to detect.

Compared to earlier submarines in the Soryu-class, Oryu doesn’t use lead-acid batteries but lithium-ion ones, designed by GS Yuasa. These high-performance batteries are said to store about double the power.

Japanese-Built F-35A

The first Japanese-assembled F-35A was unveiled at the Mitsubishi Heavy Industries (MHI) Komaki South F-35 Final Assembly and Check Out (FACO) facility here on June 5, 2017. The Japan F-35 FACO is operated by MHI with technical assistance from Lockheed Martin and oversight from the U.S. Government.

Approximately 200 people attended the ceremony including Japanese and United States government and defense industry leaders. The ceremony highlighted the strong partnership between the Japanese Ministry of Defense, U.S. Department of Defense, MHI and Lockheed Martin.

Kenji Wakamiya, senior vice minister of defense; General Yoshiyuki Sugiyama, Japan Air Self Defense Force (JASDF) chief of staff; Lieutenant General Jerry Martinez, commander, U.S. Forces Japan and 5th Air Force; Vice Admiral Mat Winter, F-35 Program Executive Officer; Vice Admiral Dave Lewis, Defense Contract Management Agency Director; Naohiko Abe, MHI’s senior vice president and Integrated Defense & Space Systems president, and Orlando Carvalho, executive vice president of Lockheed Martin Aeronautics, attended the milestone event.

«Seeing the first Japanese built F-35A is a testament to the global nature of this program», said Vice Admiral Mat Winter, F-35 Program Executive Officer. «This state of the art assembly facility, staffed with a talented and motivated workforce, enables us to leverage industry’s unique talents and technological know-how to produce the world’s best multi-role fighter. The F-35 will enhance the strength of our security alliances and reinforce long-established bonds with our allies through training opportunities, exercises, and military-to-military events».

The Japanese Ministry of Defense competitively selected the F-35A as the JASDF’s next-generation air defense fighter in December 2011, with a Foreign Military Sales program of record of 42 F-35As. The first four JASDF F-35As were previously delivered from the Fort Worth, Texas, production facility. Subsequent deliveries of 38 F-35A aircraft will come from the FACO here in Japan.

Additionally, the U.S. Department of Defense selected the Nagoya FACO in 2014 for the North Asia-Pacific regional heavy airframe Maintenance Repair Overhaul & Upgrade (MROU) facility.

«Building upon our enduring relationship with Japanese industry, we are fully committed to our F-35 production partnership with MHI and our support to the Japan Ministry of Defense», Carvalho said. «The skilled workers who achieved this milestone know firsthand the F-35’s capability and how this aircraft will only strengthen the U.S.-Japan Security Alliance, thereby building upon Japan’s strategic vision to ensure the Alliance remains strong for decades to come».

The F-35 Lightning II is a next-generation fighter, combining advanced stealth with fighter speed and agility, advanced mission systems, fully fused sensor information, network-enabled operations and cutting-edge sustainment. More than 220 operational F-35s have been built and delivered worldwide and they have collectively flown more than 95,000 flight hours.

The aircraft took off from Nagoya Airport and went through a series of trials to confirm basic maneuvers including climbing, descent and circling operations. After 23 minutes X-2 then landed at the Japan Air Self-Defense Force’s Gifu Air Base, some 50 km to the north.

After completing the maiden flight, the pilot, from MHI, described the flight experience as «extremely stable». «Control of the aircraft went exactly as in our simulated training sessions», he said, «and after piloting the aircraft I’m 100% positive the X-2 is magnificent and will meet the Ministry of Defense’s requirements».

The X-2 is a prototype stealth aircraft – the first in Japan to feature technology impeding its detection by radar – engineered for extremely high maneuverability. The prototype integrates an airframe, engines, and other advanced systems and equipment all adaptable to future fighters.

As the coordinating company of the X-2 development project, MHI has been developing the aircraft’s airframe since 2009 with cooperation provided by 220 domestic companies and guidance from Japan’s Acquisition, Technology & Logistics Agency (ATLA). In this way, world-class cutting-edge technologies developed in Japan are featured throughout the prototype unit.

Going forward MHI will continue to develop, manufacture and support the operation of defense aircraft incorporating the world’s leading technologies, thereby contributing to Japan’s national security.
