    Japan unveils its hypersonic weapons plans

    By: Mike Yeo MELBOURNE, Australia — Japan has outlined its research and development road map for its homegrown, standoff hypersonic weapons, confirming that it is seeking an incremental growth in capability and providing more details about the kinds of threats it is targeting with this new class of weapon. In a Japanese-language document published on the Acquisition, Technology and Logistics Agency website, the government said two classes of standoff hypersonic systems will be deployed — the Hypersonic Cruise Missile (HCM) and the Hyper Velocity Gliding Projectile (HVGP). The former will be powered by a scramjet engine and appears similar to a typical missile, albeit one that cruises at a much higher speed while capable of traveling at long ranges. The HVGP, on the other hand, will feature a solid-fuel rocket engine that will boost its warhead payload to a high altitude before separation, where it will then glide to its target using its altitude to maintain high velocity until impact. The agency also provided more details regarding warhead payloads, with different warheads planned for both seaborne and land targets. The former will be an armor-piercing warhead designed specifically for penetrating “the deck of the [aircraft] carrier,” while a land-attack version will utilize a high-density, explosively formed projectile, or EFP, for area suppression. Area suppression effects for the latter will be achieved via the use of multiple EFPs, which are more commonly known as a shaped charge. An EFP is made up of a concave metal hemispherical or cone-shaped liner backed by a high explosive, all in a steel or aluminum casing. When the high explosive is detonated, the metal liner is compressed and squeezed forward, forming a jet whose tip may travel as fast as 6 miles per second. Japan's road map also revealed the country is taking an incremental approach with regard to designing the shapes of warheads and developing solid-fuel engine technology, with plans to field early versions of both in the 2024 to 2028 time frame. They are expected to enter service in the early 2030s. The agency expects both systems to navigate via satellite navigation with an inertial navigation system as backup. Japan is seeking to establish a network of seven satellites to enable continuous positioning for its self-defense forces, which will enable it to provide continuous navigation data without relying on foreign satellites. Warhead guidance is achieved via either radio-frequency imaging converted from doppler shift data — which the government agency said will be able to identify stealthy naval targets in all weather conditions — or an infrared seeker capable to discriminating specific targets. Japan has been conducting R&D into various areas related to hypersonic weapons for a number of years, although most of it was to benefit other fields like satellite navigation and solid-fuel rockets. More work remains, however, in areas like hypersonic guidance systems, warhead and missile-body thermal shielding, and hypersonic propulsion systems in order for Japan to be able to field a viable standoff hypersonic weapons capability. https://www.defensenews.com/industry/techwatch/2020/03/13/japan-unveils-its-hypersonic-weapons-plans/

    What the Pentagon could learn from unicorns

    By: Jill Aitoro WESTLAKE VILLAGE, Calif. — The promise of Silicon Valley is built on unicorns — startup companies valued at more than $1 billion. They're rare. Hence the name. But the payoff is big enough that venture capitalists are willing to funnel a lot of money by way of multiple rounds of funding toward unproven technologies, to accept significant risk, in hopes they'll be in on the ground floor of the next great discovery. Compare that to Washington, where in the words of Defense Innovation Board Executive Director Josh Marcuse: “We put forward a defense program full of things that we know aren't going to work, but no one is willing to say so.” For more than three years the Pentagon has attempted to draw upon the Silicon Valley culture of innovation, to buy instead of build, to take advantage of commercial technology. But success has been spotty at best — with SpaceX and Palantir rather exclusively held up as the two “unicorns” catering to the military. But while many procurement reformists will point to burdensome regulations as the problem, innovation leaders from both the Department of Defense and Silicon Valley companies agreed during a November roundtable hosted by Defense News that no laws currently in place prevent smart buying by the government. Instead, those same innovation leader say that what causes the greatest minds in the tech community to walk away from the largest buyer in the world is a slow, arduous process combined with a serious lack of understanding within the Pentagon for how software is designed. “We basically created an innovation program where you have to have Howard Hughes-style entrepreneurship to do anything that matters,” said Trae Stephens, partner at San Francisco-based venture capital firm Founders Fund and co-founder of Silicon Vally tech firm Anduril. To buy or to build Since the 1990s, defense acquisition regulations have clearly stated that commercial preference should be given in every contracting decision. Reinforcing that point, the Office of the Secretary of Defense for Acquisition, Technology, and Logistics released a guidebook for acquiring commercial items in January 2018, stating: “The time and cost to develop and field new capabilities, the technological advances made by near peer competitors and the rapid pace of innovation by private industry have demonstrated the need to access the best technology — now.” And yet, such earnest support of commercial tech does not regularly filter to the acquisition community. Agencies over-specify requirements, “so now if the company wants to do business with [the Pentagon], they have to modify their product,” Stephens said. “All you have to do is say, ‘Yes, we have validated that there is no commercial product that meets our requirements,' and that's it.” The Pentagon does not, however, do the opposite — adapt requirements for a particular product. “There are a lot of things that we just have to build. We're going to build aircraft carriers, we're going to build fighter planes,” Stephens added. “And then there's the thing that we're going to buy — the products. These should be entirely separate conversations.” That over-specification runs counter to the “agile” development method typically favored by the tech community, which is built on a premise of short sprints that factor into evolving requirements. Agile can't exist without a degree of flexibility, ensuring, too, that if you fail, you fail fast. Contrast that with the traditional waterfall approach that predefines the various phases of development to ensure, in theory, a predictable outcome.
