  Japanese acquisition officials reveal next steps in search for advanced fighter jet

  By: Mike Yeo TOKYO — Japan is pushing ahead with research and development into advanced fighter jet technology, despite uncertainty over its acquisition strategy for a next-generation fighter and questions about the degree to which Japanese industry will be involved in the program. These technologies include a new fighter engine, thrust vectoring control, stealth shaping for low observability as well as the weapons carriage and release mechanism for internal weapons bays, according to representatives from Japan's Acquisition, Technical and Logistics Agency, or ATLA, who spoke at the Japan International Aerospace Exhibition in Tokyo, which ended Nov. 30. Several of these technologies were fitted on the Mitsubishi X-2, a technology demonstrator built by the Japanese and used to test and validate several of these features. Since then Japan has continued development work on the 15-ton thrust XF-9 afterburning turbofan. That turbofan displayed an improvement up to 70 percent during the time it took to spool up to full thrust from idle, when compared to the earlier XF-5 used by the X-2, said Lt. Gen. Hiroaki Uchimura, director general of aerial systems at ATLA. Japan is also working on an advanced active electronically scanned array radar, as well as manufacturing techniques to reduce or eliminate the need for fasteners in aircraft structures. Neither feature found its way to the X-2, but work continues on both fronts, with the radar having been tested in the laboratory and slated for flight tests onboard a Mitsubishi F-2 fighter jet test bed. The continuing R&D effort is reflected in the budget requests the Ministry of Defense made for next fiscal year, which begins in April 2019. This includes $194.6 million for research into fighter “mission system integration studies and manned-unmanned aircraft teaming technology,” and is on top of the $1.7 billion Japan has invested in fighter research since 2009. That first figure is also more than 10 times the amount spent on R&D for Japan's Mitsubishi F-2 fighter, according to Uchimura. Japan's next-generation fighter will replace the F-2 around the mid-2030s, and both Uchimura and ATLA Commissioner Nobuaki Miyama, who spoke at different conference sessions at the aerospace exhibition, touched on five critical attributes for Japan's next fighter program. These include its ability to secure air superiority over potential adversaries; the ease of upgrading as new technologies emerge; the latitude to domestically perform upgrades and sustainment without requiring overseas approval; the level of involvement of local industries in performing those upgrades and sustainment; and the need for the fighter and program as a whole to have a “realistic and feasible” cost. Japan is currently studying several different procurement strategies for its next-generation fighter, including a wholly domestically developed and manufactured design, an international collaboration, or what it calls a “spinoff” development of an existing design. Japan and the United Kingdom have agreed to exchange information with each other for their respective fighter programs. Reuters previously reported that both Lockheed Martin and Northrop Grumman responded to Japan's request for information on potential fighter offerings, with the former said to have an “F-22/F-35 hybrid” in mind. https://www.defensenews.com/digital-show-dailies/japan-aerospace/2018/11/30/japanese-acquisition-officials-reveal-next-steps-in-search-for-advanced-fighter-jet

  Lockheed Martin Skunk Works®' Project Riot Demonstrates Multi-Domain Operations

  PALMDALE, Calif., Sept. 16, 2019 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) Skunk Works®, the Missile Defense Agency and the U.S. Air Force successfully connected an F-35, U-2 and a multi-domain ground station in a ground-breaking test demonstrating multi-domain operations and the secure distribution of sensitive information across multiple platforms. During the demonstration, called Project Riot, an F-35 detected a long-range missile launch with its onboard sensors and shared the information through the U-2 to the air defense commander on the ground, enabling the commander to quickly make the decision to target the threat. This next-level connectivity reduces the data-to-decision timeline from minutes to seconds, which is critical in fighting today's adversaries and advanced threats. In partnership with the Air Force Life Cycle Management Center at Hanscom Air Force Base, Massachusetts, and the Missile Defense Agency, Skunk Works' Project Riot builds on a series of open systems architecture demonstrations proving how incremental increases in capability can be rapidly fielded to enable a connected network across air, ground, sea, space and cyber domains. "This demonstration continues our commitment to provide complete battlespace awareness and seamless interoperability to enable multi-domain operations," said John Clark, vice president of ISR & UAS at Lockheed Martin Skunk Works. "With its long-range standoff sensors, on-board processing and ability to operate in and around contested environments, the U-2 continues to play a critical role in demonstrating new capabilities today, while transforming operations for tomorrow's battlespace." Leveraging common industry standards to drive down cost and shorten schedules, the team achieved four mission critical data points in less than four months: Demonstrated the ability to leverage F-35 sensor data for missile defense Leveraged the modernized U-2's extensive payload capacity, modular design and open architecture to provide beyond line of sight communications between the F-35 and a multi-domain ground station Established two new data paths to securely transmit 5th generation sensor data at multiple levels of security to the warfighter, enabling a multi-domain network of legacy and 5th generation systems Disseminated 5th generation data using the Air Force's Universal Command and Control Interface and Open Mission Systems standards for faster capability deployment and seamless connection between systems "The F-35, with its advanced sensors and connectivity, is able to gather and seamlessly share critical information enabling the joint force to be safer and more effective," said Greg Ulmer, Lockheed Martin vice president and general manager for the F-35 program. "No other fighter jet in the world has this capability – and this test was a critical step on the path to unlocking its full potential for multi-domain operations." This demonstration builds on successful flight tests completed since 2013 that establish the foundation for a distributed, systems-of-systems architecture in the not-too-distant future.
