US Air Force's new B-21 Raider "flying wing" bomber takes first flight | Reuters

The U.S. Air Force's B-21 "Raider" bomber shaped like a flying wing took its first flight on Friday, the next step in rolling out a new fleet of long-range nuclear-capable stealth bombers built by Northrop Grumman , according to a Reuters witness.

    Army leans on scientists to push the boundaries of munitions range, precision, lethality

    By: Todd South Army researchers are speeding up development on key conventional munitions, from field artillery to long-range missiles, and making them more deadly when they land. At a panel hosted by Defense News at the annual Association of the United States Army annual meeting, commanders with the Army's Research, Development and Engineering Command, Program Executive Office-Ammunition and the Long-Range Precision Fires Cross-Functional Team gave a few updates on those efforts. Brig. Gen. Alfred Abramson III, head of PEO Ammo and Picatinny Arsenal, New Jersey, told audience members that his researchers are finding the quickest ways to go after extending ranges, saying that the XM1113 round will be “critical” for the conventional artillery in the Extended Range Cannon Artillery program, a centerpiece of artillery modernization. Abramson noted that the existing M795 High Explosive artillery round, the base of the 155mm munition portfolio, includes about 614,000 rounds in the nation's stockpile. But those rounds only reach out to about 30 kilometers. The problem developers face in pushing the ranges of conventional rounds is keeping them both accurate and having a real effect when they strike, he said. “You want to push it out to 70 kilometers and ensure it's not just a long-range paintball,” Abramson said. The XM1128 pushes those ranges to about 40 kilometers currently. But work with “lithographic fragmentation technology,” Abramson said, makes the round more lethal on target. Col. John Rafferty, director of the LRPF CFT, said that recent testing has gotten 155mm artillery rounds to the 60-kilometer range at the Yuma, Arizona, testing facility. Abramson said that his organization has seen a significant spike of about $2.5 billion for fiscal years 2017 to 2022 funding for ammunition and armament systems products. Another $1.5 billion has been allotted to update the aging ammunition manufacturing plants across the Army, he said. Recent Overseas Contingency Operations funding for 2019 was marked at about $4.1 billion simply to replenish munitions consumed during combat. What's being done to advance the science? Maj. Gen. Cedric Wins, commanding general of U.S. Army Research, Development and Engineering Command, said that over the past year, $900 million was realigned for science and technology development for the LRPF initiatives, and another $500 million was also realigned for the Air Missile Defense CFT. His organization just completed a six-month study of energetics propulsion that included a detailed study of adversary capabilities and advancements over the past two decades. It also looked at how those advances were achieved and what gaps exist in the United States' armaments, he said. While the study has not yet been released to the public, he said two non-technical gaps that the United States must correct are in their ability to collaborate with global partners and science, chemistry and energy experts within government. Further down the development pipeline he said was a shortfall in transitioning the research to the PEOs for development and fielding. One tech challenge is the existing stockpiles. As the developers push the capacities of conventional rounds and their systems they must also maintain “backwards compatibility” with the substantial munition stockpiles, he said. https://www.armytimes.com/news/your-army/2018/10/08/army-leans-on-scientists-to-push-the-boundaries-of-munitions-range-precision-lethality

    Air Force studying the future of coordinated air, space, cyber ops

    By: Mark Pomerleau The Air Force is on the cusp of completing a 16-month study that could serve as a blueprint for how the service will operate in the 2030s and seamlessly coordinate between air, cyber and space. All of the military services are re-organizing to better prepare multi-domain battle, which involves seamless coordination of effects and operations across the five domains of warfare. Multi-domain command and control, known as MDC2, has been a top priority for Air Force chief of staff Gen. David Goldfein since his confirmation hearing in June 2016. The Air Force for the last 16 months has been working a highly anticipated study on the subject. In fact, the team has nearly completed the multi-domain command and control (MDC2) study and will brief the Air Force's senior leaders Nov. 27, Brig. Gen. Chance Saltzman, director of current operations and the lead on the project, said during a breakfast hosted by the Mitchell Institute for Aerospace Studies Nov. 17. Why the change? Many military leaders have stressed that changes in organization, concepts and doctrine are due to the perceived threat environment of the future. The Air Force's pursuit of MDC2 is no different. While the Air Force has been conducting operations in multiple domains for years, the threat picture in 2030 — to include anti-access area denial, anti-satellite weapons, directed energy weapons, computer network attack — is necessitating this change. Moreover, future battlefields will include urban, multi-regional, multi-domain, multi-component, joint, multi-national and will unfold at unprecedented speeds. One of the primary conclusions of a recent study on Air Superiority 2030 was that the Air Force's structure in 2030 would struggle against this type of threat unless the service moves to multi-approach to operations, Saltzman said, Full article: https://www.c4isrnet.com/c2-comms/2017/11/17/air-force-wrapping-up-study-on-how-to-use-air-space-and-cyber-in-the-2030s/

    NORAD boss wants to get creative about defeating cruise missiles

    The U.S. commander responsible for North America says he's open for new ways to defend against cruise missile attacks on the homeland, including electronic warfare and other non-kinetic means.
