    Japan at a crossroads: What’s keeping its defense industry from growing?

    By: Mike Yeo MELBOURNE, Australia — Japan is facing what appears to be an increasingly difficult choice, between a desire to keep its domestic defense industry in business, and getting more value for its defense spending while introducing much-needed capabilities by buying foreign off-the-shelf systems. This conundrum comes as the U.S. ally continues to warily eye nearby China's military buildup and North Korea's missile and nuclear programs. Japan's defense industry came to being soon after the end of World War II, as it attempted to rebuild its shattered economy. According to Corey Wallace, a postdoctoral fellow at the Graduate School of East Asia Studies at Germany's Freie Universität Berlin, Japan adopted what was known as kokusanka — a conscious and systematic attempt to domesticate technologies that Japan would need for an autonomous defense-industrial base. Through licensing agreements and other methods of technology transfer and acquisition, the Japanese government in the post-war period identified the most important platforms it thought it needed and tried to domesticate them. Today, Japan's local industry produces all of the country's warships and submarines, albeit fitted with important systems like the Aegis combat system, radars and missiles from the United States as well as most of its land warfare systems. Despite these capabilities, there are a number of hurdles for Japan's defense-industrial base. Chief among these is the relatively small, domestic market that drives up unit prices as well as Japan's own set of unique requirements that sometimes create a bespoke product difficult to market overseas. The small, domestic market has also meant there is little competition. And when the price of a product is determined by what Japanese newspaper Asahi Shimbun calls the “cost calculation method,” in which a contractor's profit is added to the prime cost that also includes that of materials and labor, it can lead to “an open invitation for soaring costs as contractors have few incentives for suppressing the prime cost.” An example of this is the C-2 airlifter. Since 2016, Japan has ordered a total of seven C-2 aircraft out of an eventual requirement of 40. This slow production rate means the C-2 costs about $201 million per aircraft, according to the latest budget request from Japan's Defense Ministry, which has asked to procure two aircraft in the next fiscal year. This, coupled with the need to focus on the expensive missile defense systems against the North Korean ballistic missile threat, has put Japan's defense budget under strain, to the point that earlier this year Japan's Finance Ministry reportedly took the unorthodox step of urging its defense counterpart to consider the option of acquiring a cheaper airlifter instead of the C-2. Given recent developments in the geopolitical and domestic industrial sphere, Japan has turned to what Wallace calls “selectivity and concentration” — the country accepts that its defense-industrial base cannot achieve absolute autonomy, particularly in areas like fighter jets and ballistic missile defense, where international cooperation is necessary in the development process. Foreign partnerships Cooperation with a foreign partner appears to be the way Japan is proceeding with two key aerospace programs: the development of a new air-to-air missile and its next fighter jet. Japan is developing the Joint New Air-to-Air Missile, which will marry the active electronically scanned array radar seeker of Japan's AAM-4B air-to-air missile with the European MBDA Meteor ramjet-powered beyond-visual-range air-to-air missile. The missile is intended for use by the Japan Air Self-Defense Force, but the program appears to be on a long timeline. Reports indicate no technical work has been done, and the first prototypes are planned to be ready for test shots after April 2022, with a decision following on whether to go ahead with the program. With regard to its next-generation fighter jets, following a request for information from several overseas manufacturers earlier this year, Japan is reportedly studying the feasibility of a joint development program. Local media has tracked the story, although official information is scant pending the release of Japan's five-year midterm defense plan later this year. It's widely expected Japan will link up with a foreign partner for the development, however some are holding out hope for a wholly domestic fighter program despite the risks and higher costs involved. Japan has not locally built fighters since Mitsubishi F-2s rolled off the line in 2011. However, Grant Newsham, a retired U.S. Marine Corps officer who is now a senior research fellow at the Japan Forum for Strategic Studies in Tokyo, says Japan should consider spending more on defense, telling Defense News earlier this year that figure should be about $5 billion to $7 billion more per year for the next five years. As the world's third-largest economy, he said, “Japan has all the money it needs to properly fund defense. And the amounts required are about the same as the waste and/or fraud in a couple of public works projects, but it chooses not to do so.” Japan's latest defense budget request for the next fiscal year is for $48 billion, which is a 2.1 percent increase from the previous year's allocated budget and represents a new record-high defense budget for the country. The amount is roughly 1 percent of its gross domestic product, which, although not official policy, has essentially become a ceiling for its defense budget. Notably, Japan is carrying out final assembly on most of its 42 Lockheed Martin F-35A Lightning II Joint Strike Fighters, which will eventually replace the upgraded F-4EJ Kai Phantom II aircraft currently in service. The government reportedly wants to buy more F-35s, with some suggesting it's looking at the short-takeoff-and-vertical-landing F-35B to equip the flight decks of its helicopter destroyers of the Japan Maritime Self-Defense Force. Export challenges Under Prime Minister Shinzo Abe, Japan has ended its ban on defense exports, which his government sees as a way to boost Japan's economy. Japanese defense companies have and continue to pursue several international acquisition programs ranging from Australia's requirement for submarines to France and Germany's requirement for new maritime patrol aircraft. However, these export opportunities have presented their own set of challenges, not least the fact that Japanese companies lack the savvy of their more-experienced competitors at the higher end of the global arms market, and that they're being priced out by cheaper alternatives at the lower end. And despite their undoubted quality, Japanese offerings are sometimes hindered in the export market by the domestic market's bespoke requirements. In the case of the C-2, there were no requirements for the aircraft to conduct operations on short or poorly prepared airstrips, and this is likely to hurt its prospects in New Zealand, which is seeking airlifters for both strategic and tactical airlift missions. In this case, the ability to operate from poorly prepared runways is important given the Royal New Zealand Air Force conducts regular operations to South Pacific islands, particularly on humanitarian assistance and disaster response missions in the aftermath of natural disasters. Newsham noted that despite the recent loosening of restrictions, there has not been significant effort by Japanese companies to dive into the international defense market, as most major Japanese companies don't consider the defense business to be profitable. Other sources in Japan who are familiar with the industry have corroborated that view in speaking to Defense News. And Newsham adds that despite being the administration that pushed for the loosening of defense export restrictions, the Abe government has not proactively supported Japanese defense companies seeking to do business overseas. https://www.defensenews.com/industry/2018/11/26/japan-at-a-crossroads-whats-keeping-its-defense-industry-from-growing

    France wonders: Can we always count on American support?

    By: Pierre Tran PARIS — The U.S. is a close and valued ally to France, but the European country seeks continentwide strategic autonomy in defense and security, with a stronger and more cooperative industrial base, said French Armed Forces Minister Florence Parly. “The United States is our ally and our friend, and it will remain so,” she said Sept. 11 at the Summer defense university, a gathering of parliamentarians, officers and foreign guests. “Our cooperation in defense and security is intense and highly valued.” Parly had planned to pass on that message when she saw U.S. Defense Secretary Jim Mattis in Washington on Thursday, but that trip to the U.S. — which included a presentation at the Atlantic Council — was canceled due to Hurricane Florence hitting the East Coast. “Can we always count, in every place and in every circumstance, on American support?" she said. “Listen to the statements of the U.S. president, read his tweets: The message sent is clear and without ambiguity,” she added. “We have to count on ourselves ... build a European strategic autonomy.” But Robbin Laird, an analyst with U.S.- and France-based consultancy ICSA, said the U.S. is very present in Europe. “Despite the president's comments on NATO and Article 5, his administration has committed significant resources in Europe,” he said, referring to the alliance's charter that calls for a united response should a member nation come under attack. Mattis was recently “very visible in Finland,” attending a trilateral meeting with Finnish and Swedish senior officials, Laird said, noting the upcoming NATO Trident Juncture exercise in Norway in October and November. “It is clear Trump would welcome a more European capability; a real defense capability is what he is looking for, not just words,” he said. On the industrial front, Parly said France and Germany have signed up for projects for a Future Combat Air System — centered on a new fighter jet— and a new tank. This is a “historic step for Europe, for the future of our equipment and the strength of our industry,” she said. These were long-term commitments, open to other nations, she added.

    DARPA Awards Six Teams During Final Spectrum Collaboration Challenge Qualifier

    On December 12, DARPA held the second preliminary event of the Spectrum Collaboration Challenge (SC2) – the world's first collaborative machine-intelligence competition to overcome spectrum scarcity. Fifteen teams represented by members from across the academic, commercial and defense landscapes gathered at Johns Hopkins University Applied Physics Laboratory (APL) to pit their intelligent radio designs against each other in a head-to-head competition. At the event's conclusion, six of the eight top-scoring teams walked away with $750,000 each in prize money. While not all competitors received interim prizes, all 15 teams have an opportunity to move on to the next stage and compete in the 2019 Spectrum Collaboration Challenge grand finale, which will be held in conjunction with MWC19 Los Angeles, in partnership with CTIA, on October 23, 2019. The six prize-winning teams from the second preliminary event are: Zylinium, a team of independent researchers MarmotE from Vanderbilt University Sprite from Northeastern University Erebus, a team of independent researchers Gator Wings from University of Florida SCATTER from IDLab, an imec research group at Ghent University and University of Antwerp, and Rutgers University "During the second preliminary event we witnessed a technological shift," said Paul Tilghman, the DARPA program manager leading SC2. "For the first time, we saw autonomous collaboration outperform the status quo for spectrum management." Starting in early December, each team's radio participated in 105 matches against competitors in the Colosseum, a massive RF testbed that was developed specifically for SC2. The matches were held in a round-robin fashion where each radio network – working in groups of threes, fours or fives – had multiple opportunities to compete against every other radio design in the competition. Roughly 400 matches were held in total to determine the final team rankings and the prize recipients. During the PE2 matches, teams were put through six different RF scenarios designed to mimic the challenges that collaborative, autonomous radios will face in the real world. These scenarios challenged the radios to collaboratively mitigate interfering with an incumbent radio system, sense and adapt to the spectrum demands of high-traffic environments, handle the data demands of the connected soldier of the future, and beyond. Each scenario was designed to pressure test various elements of the teams' approaches and, in particular, their ability to successfully collaborate with the other radios operating within the same environment. “The six different scenarios were closely aligned to actual situations that our defense and commercial systems face in the field. The Wildfire scenario, for example, replicates the complex communications environment that surrounds an emergency response situation, while the Alleys of Austin scenario was designed to mimic what's needed to help dismounted soldiers navigate and communicate as they sweep through an urban environment. This real-world relevance was critical for us as we want to ensure these technologies can continue to develop after the event and can transition to commercial and/or military applications,” said Tilghman. The sixth scenario of the competition was used to determine the six prize winning teams. This scenario explored the essential question of the SC2 competition: can the top teams' collaborative SC2 radios outperform the status quo of static allocation? Each of the six teams that received awards at PE2 demonstrated that their radio was capable of carrying more wireless applications without the aid of a handcrafted spectrum plan, while simultaneously ensuring four other radio networks operating in the same area had improved performance. In short, each of these six radio networks demonstrated the autonomous future of the spectrum. To aid with decision making, teams applied AI and machine learning technologies in various ways. Some leveraged the current generation of AI technologies like deep learning, while others used more conventional optimization approaches. There were also a few teams that used first wave, rule-based AI technologies. “We're very encouraged by the results we saw at PE2. The teams' radios faced new and unexpected scenarios but were still able to demonstrate smart, collaborative decision making. PE2 showed us that AI and machine learning's application to wireless spectrum management creates a very real opportunity to rethink our current century-old approach,” said Tilghman. The competition now enters its third year and moves closer to the finale, which will be held at one of the country's largest annual technology and telecommunications shows – MWC19 Los Angeles. More than 22,000 attendees from the broad mobile ecosystem and adjacent industry sectors will convene at this three-day event to discuss the current opportunities and future trends shaping the industry. The SC2 championship event will be held on the keynote stage of MWC19 Los Angeles on October 23, 2019. At the conclusion of SC2's finale, three teams will be awarded $2 million, $1 million and $750,000, respectively, for first, second and third place. The real prize, however, will be the promise of a more efficient wireless paradigm in which radio networks autonomously collaborate to determine how the spectrum should be used moment-to-moment, helping to usher in an era of spectrum abundance.
