Japan reveals plan for space defense unit

TOKYO — Japanese Prime Minister Shinzo Abe said Monday his country will form a space defense unit to protect itself from potential threats as rivals develop missiles and other technology, noting that the new unit will work closely with its American counterpart recently launched by President Donald Trump.

The Space Domain Mission Unit will start in April as part of Japan's Air Self-Defense Force, Abe said in a policy speech marking the start of the year's parliamentary session.

He said Japan must also defend itself from threats in cyberspace and from electromagnetic interference against Japanese satellites. Concerns are growing that China and Russia are seeking ways to interfere, disable or destroy satellites.

“We will drastically bolster capability and system in order to secure superiority” in those areas, Abe said.

The space unit will be added to an existing air base at Fuchu in the western suburbs of Tokyo, where about 20 people will be staffed ahead of a full launch in 2022. The role of the space unit is to conduct satellite-based navigation and communications for other troops in the field, rather than being on the ground.


Abe’s Cabinet in December approved 50.6 billion yen (U.S. $459.2 million) budget in space-related projects, pending parliamentary approval.

The unit will cooperate with U.S. Space Command that Trump established in August, as well as Japan’s space exploration agency, Japan Aerospace Exploration Agency.

Underscoring the need to step up cybersecurity, Mitsubishi Electric Corp. revealed Monday that it had suffered a cyberattack last June that may have compromised personal and corporate data involving thousands of its job applicants, employees and retirees. Mitsubishi said there was no breach of sensitive data in the company’s operations involving defense, space, transportation, electric power and other businesses sectors. It promised to enhance security measures and monitoring.

Abe has pushed for Japan’s Self-Defense Force to expand its international role and capability by bolstering cooperation and weapons compatibility with the U.S., as it increasingly works alongside American troops and as it grows concerned about the increasing capabilities of China and North Korea.

Abe, in marking Sunday’s 60th anniversary of the signing of a Japan-U.S. security treaty, vowed to bolster the island nation’s capability and cooperation with the U.S., including in the areas of space and cybersecurity.

He said he is determined to settle Japan’s “unfortunate past” with North Korea, as he hopes to “sum up” his country’s post-war legacies before his term expires next year.


He reiterated his intention to hold talks with North Korean leader Kim Jong Un without the conditions he had demanded in the past — denuclearizing the Korean Peninsula and resolving the decades-old issue of abductions of Japanese citizens by North Korea.

Part of Abe’s plan while in office is to achieve his long-cherished goal of revising Japan’s U.S.-drafted constitution that prohibits use of force in settling international disputes. Despite Abe’s push, chances are fading for the revision due to a lack of public interest and the opposition’s focus on other controversial issues such as Japan’s recent dispatch of naval troops to the Middle East and the questionable public record-keeping at Abe’s annual cherry blossom-viewing parties.

In a sign of a thaw in Japan’s recently tense relations with South Korea, Abe said he planned to cooperate closely with South Korea in dealing with a harsh security environment in northeast Asia.

Abe, however, repeated his demand that South Korea resolve the issue of compensation for the former Korean laborers during Japan’s 1910-1945 colonial rule. “I hope (South Korea) to keep its promise between the two countries and build future-oriented bilateral relations,” he said.
 
Abe is a weird guy and I sort of suspect he has some hidden motives.
 
Japan decided to follow America’s example, huh? Now that a second big-name country is cooking up a space defense force (SDF, heh) of their own, I won’t be surprised if more and more nations begin to follow suit.
 
Have they even launched a rocket yet? Is this real or just another big government promise with no intention to fulfil it (Note that Japan also happens to be a one party state)

I got my witty post in, but let me ramble on a bit on reality. This is gonna be a ticket to defense spend, and fund space travel over all for the Japanese, frankly it's not a bad idea. We know they do not get along with China, and have been playing stare down past few years. The US has a pact with the Japanese since ww2 for protecting them, they are flexible with that "helo carriers" my ass. That I won't sperg on but let's just say Japan is becoming more self sustaining in mil regards.

I don't think when they signed up to be protected, and to this day there were really any rules about space warfare etc. As a rather wealthy tech forward nation with a wild west of space rules (there are some but not a ton) it's not a bad idea to weaponize space, because like it or not it's coming and it will be a thing, be it smacking satellites around with cheaper ones, to jamming stuff and maybe even some laser zapping. Who knows whats coming and a forward thinking nation knows it's not a bad idea to start prepping for it.

Yes, several.

Rocket history
Japan launched its first satellite, Ohsumi, in 1970, using ISAS' L-4S rocket. Prior to the merger, ISAS used small solid-fueled launch vehicles, while NASDA developed larger liquid-fueled launchers. In the beginning, NASDA used licensed American models. The first model of liquid-fuelled launch vehicle indigenously developed in Japan was the H-II, introduced in 1994. However, at the end of the 1990s, with two H-II launch failures, Japanese rocket technology began to face criticism.

Early H-IIA missions
Japan's first space mission under JAXA, an H-IIA rocket launch on 29 November 2003, ended in failure due to stress problems. After a 15-month hiatus, JAXA performed a successful launch of an H-IIA rocket from Tanegashima Space Center, placing a satellite into orbit on 26 February 2005.

Epsilon Rocket
To be able to launch smaller mission on JAXA developed a new solid-fueled rocket, the Epsilon as a replacement to the retired M-V. The maiden flight successfully happened in 2013. So far, the rocket has flown four times without any launch failures.

Orbital SS-520 mission
In January 2017, JAXA attempted and failed to put a miniature satellite into orbit atop one of its SS520 series rockets. A second attempt on February 2, 2018 was successful, putting a ten-pound CubeSat into Earth orbit. The rocket, known as the SS-520-5, is the world's smallest orbital launcher.
 
If this brings us closer to Minovsky particle physics becoming a reality, sweet.

On a serious note, Abe is asking the North Koreans and South Koreans for a MAJOR quid pro quo, not sure he's likely to get it.
