DARPA takes big step forward on X-plane that maneuvers with air bursts

"We’re not actually pushing the vehicle with air, we’re using it to tailor how the air is flowing over the wing,” the former CRANE program manager said.

    BREAKING: Marine Corps Planning Major Program Cuts

    By Jon Harper SIMI VALLEY, Calif. — The Marine Corps intends to divest itself of legacy systems as it transforms into a more mobile and expeditionary force, the service's commandant said Dec. 7. In recent decades Marines have been busy fighting land wars in Iraq and Afghanistan. But now they must prepare for a potential conflict in a naval environment against advanced adversaries such as China, Gen. David Berger told reporters at the Reagan National Defense Forum in Simi Valley, California. “We cannot wait any longer before we start adjusting our service to what we've got to be six, seven, eight years out,” he said. “We have lots of changes we have to make and ... we have to get rid of legacy things in the Marine Corps. We've got to go on a diet. We've got to get back on ship. We've got to become expeditionary again.” What types of legacy systems will be on the chopping block? “Big, heavy things,” Berger said. “Expensive things that we can't either afford to buy or afford to maintain over the life of it. Things that don't fit aboard ships. Things that can't fire hyper velocity projectiles. Things that don't have the range that we're going to need or the precision.” Mobility will be critical in future fights, he noted. Marines must be able to operate from ships or ashore, and move back and forth between domains. Other platforms that could see cuts include manned logistics vehicles and aircraft. “All those things we're going to trim down,” Berger said. The service is also looking to add new capabilities. The commandant did not identify specific systems that the Marines plan to buy, but he provided a flavor of the types of platforms that will be on the shopping list. “Think unmanned. Think expeditionary. Think very light. Think things that we can sustain forward without a huge logistical train,” Berger said. Unmanned logistics vehicles and aircraft are examples of new technologies that the service is interested in. Human beings will still be on the battlefield, Berger noted. “I just don't need them driving a truck delivering chow” if a self-driving platform could perform the task, he said. Drones could also deliver supplies. “Amazon does it. Why wouldn't we do it?” he asked. Unmanned combat aircraft are also on the wish list, he noted. The Marine Corps has been conducting wargames and simulations to help determine how the force should be redesigned for potential future combat scenarios that might occur 10 years out. “We're in the last stages of that,” Berger said. That effort will likely wrap up in late January or early February. Force composition changes will be made over 10 years, but some will begin next year, he said. Officials are examining “every part of our air-ground team,” Berger said. A wide range of capabilities are being looked at. “From individual equipment to crew served [weapons] to F-35s and everything in between.” The analysis will help determine which programs will be killed, trimmed or added, he said. The service needs new weapon systems that can find and kill enemy ships at range from ship or shore. “We have to become a naval force that's lethal in terms of putting at risk another naval force,” Berger said. In the future, large numbers of unmanned air and ground systems could function as motherships that launch other robotic vehicles and drones to conduct missions, he said. A major funding realignment is planned over the next five years. “You'll see a little bit of it” in the fiscal year 2021 budget blueprint, Berger said. “The big muscle movement — that will come in ‘22, ‘23, ‘24 in a big way.” https://www.nationaldefensemagazine.org/articles/2019/12/9/marine-corps-planning-major-program-cuts

    US Army nears decision on who will build new missile defense radar prototypes

    By: Jen Judson WASHINGTON — The Army is nearing a decision on who will build its Lower-Tier Air-and-Missile Defense Sensor, or LTAMDS, which will provide the sensing capability for the future Integrated Air-and-Missile Defense System the service is developing. The service is planning to award a contract no later than the end of the fiscal year to one of the three vendors that participated in a “sense-off” competition at White Sands Missile Range, New Mexico, over the spring, Daryl Youngman, the deputy director in charge of Army AMD modernization, told Defense News in a recent interview. According to other sources, that decision is expected next month. The radar is part of a new AMD system that will replace the Army's Raytheon-made Patriot system. Raytheon, Northrop Grumman and a Lockheed Martin-Elta Systems team all brought radars to the White Sands sense-off and subsequently submitted proposals for the prototype competition in July. The winner will build six prototypes by the end of FY22 to prove whether the radar can be built and then fielded to a unit for evaluation. A follow-on contract for 16 additional radars is expected if all goes well. The plan leaves an opening for other radar solutions to get back in the game if the prototyping effort does not pan out. While the Army has dropped its long-prioritized requirement for a radar capable of detecting threats from 360 degrees, it now seeks a broader baseline requirement to “expand the battle space beyond what the current Patriot radar has,” Youngman said. And the system will ideally have a lot of growth potential baked in, he added. Replacing the Patriot radar has been a long time coming. The radar was first fielded in the 1980s, and the Army previously attempted to replace the system with Lockheed Martin's Medium Extended Air Defense System through an international co-development effort with Germany and Italy. But that program was canceled in the U.S. after closing out a proof-of-concept phase roughly six years ago. Since then, the Army has studied and debated how to replace the Patriot radar while Raytheon continues to upgrade its radar to keep pace with current threats. It is acknowledged that there will come a point where radar upgrades will be unable to keep up with future threats. Taking years to decide, the service moved forward on a competition to replace the radar in 2017 and chose four companies to come up with design concepts for the capability — Raytheon, Lockheed Martin, Northrop Grumman and Technovative Applications. Toward the end of 2018, Raytheon and Lockheed were chosen to continue technology development under that program. Defense News first broke the news last fall that the Army was attempting to hit the reset button on the LTAMDS program, deciding to host a “sense-off” to identify available radar capabilities. While LTAMDS is considered the fourth priority out of four major lines of effort with which the Cross-Functional Team in charge of AMD has defined, it is not because it's the least important, Youngman noted, but more related to schedule — where the system is in the development and fielding timeline. The AMD CFT's top priority is its command-and-control system — the Integrated Battle Command System — for its future IAMD architecture. Limited user testing will occur next spring with a decision to move into production in the fourth quarter of FY20. Manuever-Short-Range Air Defense — or M-SHORAD — is the second priority as the Army . The service is set to begin development testing of its prototypes this fall. The Indirect Fire Protection Capability (IFPC) Increment 2 program is ranked third as the Army prepares to take receipt of its interim cruise missile capability — two Iron Dome Systems — soon. The Army is in the midst of coming up with a new strategy for the IFPC system that will ultimately defend against rockets, artillery and mortar as well as cruise missiles and drone threats. The IFPC system will have to tie into the Army's IBCS system as well. https://www.defensenews.com/land/2019/08/20/us-army-nears-decision-on-who-will-build-new-missile-defense-radar-prototypes/
