Changes in Japan’s defense posture, pending aircraft buys from the U.S. and planned combat system modification to Japanese ships will give the Japanese Self Defense Force (JSDF) the practical and political ability to fight as a part of the U.S. Navy’s new networked carrier strike group concept — which would expand the lethal power and range of both forces, USNI News has learned.

(FMS) case for Japan to buy four Northrop Grumman E-2D Advanced Hawkeye information surveillance and reconnaissance aircraft for the Japanese Air Self Defense Force (JASDF).

a $70 million contract to Lockheed Martin to upgrade the Aegis combat system on its two Atago-class destroyers to the so-called Baseline 9 standard that would allow the two ships to simultaneously to target and track aircraft and ballistic missiles.

In 2011, Japan selected the Lockheed Martin F-35A Lightning II Joint Strike Fighter (JSF) as its next generation fighter.

In the U.S. Navy, E-2Ds, JSFs and Baseline 9 Aegis destroyers and cruisers are a key elements in the service’s emerging Naval Integrated Fire Control-Counter Air concept (NIFC-CA pronounced: nifk-kah).

A NIFC-CA capable carrier strike group would allow — for example — a Northrop Grumman E-2D Advanced Hawkeye to provide targeting information to a guided missile destroyer or cruiser’s Aegis combat system or Boeing F/A-18E/F fighters for a threat well outside the range of onboard sensors.

The concept also plans to use the F-35C Lightning II Joint Strike Fighter to route targeting data to E-2Ds and then to the rest of the CSG and the carrier air wing

While the U.S. has started fielding the modifications to the Aegis combat system and E-2Ds and with the new aircraft buys and ship modifications Japan’s assets could easily be folded into the U.S. concept — technically, several sources told USNI News.

Politically, recent changes in the U.S. and Japanese defense compact would allow the JSDF to work with the U.S. Navy in the more complex NIFC-CA concept.

Following last year’s reinterpretation of Japan’s pacifist constitution, the U.S. and Japan revised the so-called

which gave greater freedom to how Japan could use its armed forces.

“The Self-Defense Forces and the United States Armed Forces will provide mutual protection of each other’s assets, as appropriate, if engaged in activities that contribute to the defense of Japan in a cooperative manner,” read the new guidelines.

The change and the purchase of equipment that could integrate with the U.S. is an exception to other allies who have shirked increases in defense spending, Eric Wertheim author of

told USNI News last week.

“I think this is a strong sign showing the strengthening bonds of the US-Japanese alliance and the seriousness with which Japan takes its self defense responsibilities,” he said.
“This can be seen most notably in Japan’s recent approval of collective defense measures, but is also demonstrated by their continued military investment and acquisition programs such as the SM-3 anti-ballistic missile, Aegis destroyers and now their apparent interest in the E-2D Advanced Hawkeye aircraft.”

While Japan destroyers and E-2Ds could provide targeting data for U.S. ships, it’s unclear if Japan will purchase any Raytheon SM-6 missiles for its destroyers — a key component in the offensive side of NIFC-CA.

In its latest "Defense and space domain briefing" Japan's Mitsubishi Heavy Industries (MHI) unveiled a new surface combatant concept. Not much information is available but this new concept may be MHI's vision for the Japan Maritime Self-Defense Force (JMSDF) next generation 3000 tons class Frigate known as "30FF" or FFX.

Basically I believe both US and Japanese data link are interchangeable in which either system can communicate and swap data both ways.

The F-35 purchase is great.

But they only replace the old F-4s.

The Japanese desperately need to find a replacement for the F-2s and the F-15s. They have a few years to work it out...but they need to be very busy now planning it and getting ready.

Personally, I hope they move forward with and produce this aircraft of their own:
