    JUST IN: Defense Department to Stand Up New Counter-Drone Office

    By Yasmin Tadjdeh The Pentagon will soon stand up a counter-unmanned aerial system office that will be headed by the Army, said the Defense Department's top weapons buyer Jan. 14. Following the Dubai Air Show in November, Undersecretary of Defense for Acquisition and Sustainment Ellen Lord visited numerous locations across the Middle East including U.S. military installations in Iraq and Afghanistan. “The thing that was really top of everybody's mind were counter-UAS,” she said during a meeting with reporters hosted by George Washington University's Project for Media and National Security in Washington, D.C. “We see that small UAS are becoming a more popular weapon of choice ... [and] we need to be agile and pivot to that challenge.” Pentagon leaders recently decided to designate the Army as the executive agent for counter-drone technologies, Lord said. The new office will be stood up in Arlington, Virginia, in the Crystal City neighborhood. It will be staffed by around 60 people. “We are just finishing off on the policy that directs the activities,” she said. The office will examine the many counter-UAS efforts across the Defense Department and come up with three to five systems that are best for the military writ large and make sure they are effectively leveraged, Lord said. The Defense Department is bringing together a number of organizations, including the office of the director of operational test and evaluation and Defense Digital Service, to work on the effort. Robert Behler, the head of DOT&E, has a group conducting independent tests and evaluation of currently fielded systems, Lord noted. “Come April we will have that evaluation completed and written up. And that coincides [with] when we want to make some decisions about downselecting ... to the three to five systems that would be utilized,” she said. The department is examining a variety of sensor modalities and defeat mechanisms. “One size does not fit all,” Lord said. “You need a system with multiple sensors ... or defeat systems. And the key is really the command-and-control and then the communication across theater.” The office aims to thwart both small and large adversary UAS, she added. Countering rogue and enemy drones has long been an objective for the Defense Department, but recent high-profile events have thrown the technology into the spotlight. That includes an alleged Iranian attack on Saudi Aramaco facilities in September using unmanned aircraft. “One of the challenges is that we know that the adversary is very agile and updates their [tactics, techniques and procedures] ... very quickly,” Lord said. “We are looking at a very nimble system where we can push patches in the same day, if you will, so that we again can stay ahead of" the threat. The Pentagon is gung-go about tackling the issue, and senior leadership involvement and funding are increasing, she noted. In terms of the industrial base, counter-UAS is one of the acquisition and sustainment office's four key focus areas, Lord said. Others include microelectronics, 5G networks and hypersonics. The department plans to establish a hypersonics "war room." “We just decided last week that we would stand up a hypersonics war room to begin to look at the defense industrial base and begin to have different companies [come] in,” Lord said. The technology is the Pentagon's top research-and-development priority and it plans to buy large numbers of systems when they are mature enough to be fielded. Last week, Secretary of the Army Ryan McCarthy said missile manufacturers and other suppliers need to do more to boost their hypersonics manufacturing capability. “What we need to see is industry step up,” he said Jan. 10 during remarks at the Brookings Institution. “They've got to come forward and ... first and foremost, invest the time to work with our national lab network to understand how we've come forward with these technologies. But they're going to have to make investments to be able to produce these at scale.” https://www.nationaldefensemagazine.org/articles/2020/1/14/just-in-defense-department-to-stand-up-counter-drone-office

    Air Force establishes office at Tyndall AFB to guide five-year rebuilding process

    By Ed Adamczyk Dec. 26 (UPI) -- A Program Management Office has been established by the Air Force at Tyndall Air Force Base to lead redevelopment and reconstruction efforts there, which are expected to take more than five years and cost about $3 billion. The PMO will be responsible for leading the redevelopment and reconstruction efforts at the base after it sustained devastating damage in October from Hurricane Michael, the U.S. Air Force said in an update Wednesday.

    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/
