TOYOYAMA, Japan (AP) — Japan unveiled its first homemade stealth plane Thursday as it tries to catch up on the technology and enhance its reconnaissance and intelligence capabilities as China expands its own military presence in the region.

The experimental X-2 is expected to make its maiden test flight in February. Defense officials said the aircraft is designed to test the stealth technology that would possibly be combined with the next-generation fighter jet, replacing the fleet of F-2 fighters as early as 2028.

The red-and-white aircraft, with a 14-meter (45-foot) -long fuselage and 9-meter (30-foot) -long wingspan, sat inside a hanger at the Nagoya Airport in central Japan.

Led by Mitsubishi Heavy Industry, the stealth plane comes with radar-resistance features, including a canopy with special stealth-enhancing coating, and mobility.

"I cannot go into details, but we recognize it is technologically at a very high level," said Takahiro Yoshida, an official in charge of the project at the Acquisition, Technology & Logistics Agency of the Defense Ministry.

Antenna-minded Mitsubishi turns to seawater for conductive plume

Mitsubishi Electric, in the business of selling electrical and electronic equipment used in industries ranging from satellite communications, to energy and building equipment, is interested in coming up with innovative ways to building antennas and exploring new materials for antennas.



Making news earlier this week is their announcement of a seawater antenna which they are calling

. As the name suggests, at play here is a liquid—seawater, the most abundant resource on Earth.


David Szondy in Gizmag commented: "When someone mentions a radio aerial, it tends to conjure up a vision of something made of steel and wire. But what about one made of

?"

Mitsubishi asked the same question. The company's news release said this seawater antenna is capable of receiving digital terrestrial broadcasts for normal viewing. The interesting advantage about this concept is its indication that you can create a large antenna without having to perform massive construction.

How innovative is this development?


Szondy said, "This isn't the first seawater antenna – the US Navy has taken a keen interest in the idea in recent years.".... to read more

Here is an interesting idea for communication with subs.



Remember although you can use an antenna buoy, the antenna can be detected by radar a water plume cannot.

Japan sends more F-15s to Okinawa

Japan this weekend said it has doubled the number of F-15 fighter jets in Okinawa. The move follows continued controversy with China about islands in the East China Sea. Tokyo several years ago already replaced ageing F-4 Phantoms in Okinawa with more capable F-15s.

The newest batch of F-15s moved to Okinawa from their homebase of Tsuiki. In all, Japan now has fourty F-15s deployed to Okinawa. The most southern island of Japan also sees prolonged use by the US, although the use of Futemna airbase is subject to juridical proceedings.

The US in January already sent a squadron of its most advanced F-22 Raptors to Yokota airbase near Tokyo. This move seems directed at China as well as North Korea. The latter recently tested a suspected hydrogen bomb.

Japan Forms New Air Wing to Fend off China’s Advances in East China Sea

Tokyo has recently doubled the number of fighter jets stationed at Okinawa’s Naha Air Base.

For the first time in about 50 years, the Japan Air Self-Defense Force (JASDF) has stood up a new air wing consisting of Mitsubishi F-15J all-weather air superiority fighters at Naha Air Base, located in the capital city of Okinawa, Japan’s most southern prefecture,

to local media reports.

The stationing of additional fighter jets is part of Tokyo’s efforts to enhance the defenses of the Ryukyu Islands chain (known in Japanese as the Nansei islands), which stretches southwest from Kyushu to Taiwan. The push comes amidst China’s growing assertiveness and military presence in the East China Sea — Beijing and Tokyo both claim sovereignty over a group of uninhabited islands there, known in Japan as the Senkakus and in China as the Diaoyus.

in October 2015, the JASDF had to dispatch its fighter jets 117 times against Chinese aircraft in the third quarter of 2015, up from 103 times in the same period in 2014. Most of the encounters occurred in the East China Sea. Overall, JASDF jets were scrambled 441 times from Naha Air Base in 2015, against mostly against incursions from the People’s Liberation Army Air Force (PLAAF).

The new JASDF unit, the 9th Air Wing, was officially stood up on Sunday during a ceremony at Naha Air Base, where Japan’s Parliamentary Vice Minister of Defense Kenji Wakamiya handed the flag for the new air wing to the unit’s commander, Kiyoaki Kawanami, NHK World

.

“This is a very front line of national defense,” Wakamiya said in a speech during the ceremony. Japan dispatched 20 additional F-15J fighter jets from Tsuiki Air Base in the southwestern island of Kyushu to Naha, bringing up the total strength of the new air wing in Okinawa to 40.
