  New in 2019: Air Force looks for new bomb designs to fight Russia and China

  By: Kyle Rempfer A growing cohort of Air Force researchers are arguing that the service needs to undergo a munitions revolution if it is to take on a peer-level adversary in open conflict. “We're developing a range of technologies to enable next-generation and improve precision effects on the battlefield,” Col. Garry Haase, who helms the Air Force Research Lab Munitions Directorate, told an audience at the Air Force Association Annual Conference this fall. In some instances, that will mean more powerful munitions to breach and destroy Russian and Chinese structures in the event of war. “There is now a shift in emphasis away from minimizing to maximizing effects in a high-end fight,” said John Wilcox, vice president of advanced programs and technology at Northrop Grumman, at the conference. “Requirements from our missions directorate say we continue to have to deal with the whole spectrum of threats as we shift to more of a near-peer threat focus,” Wilcox added. “We are looking at larger munitions with bigger effects.” And while neither members of the AFA panel named Russia or China specifically, a recent study by the Mitchell Institute, which is aligned with the Air Force Association, certainly did. In the document, titled “The Munition Effects Revolution," several retired senior Air Force officers argue that the U.S. munitions arsenal is overdue for a shakeup. “The bomb body, a steel shell filled with explosive material, is relatively unchanged across the past 100 years," the study reads. "But some elements of modern munitions have significantly evolved—particularly guidance elements. Munition effects—the destructive envelope of heat, blast, and fragmentation—remain essentially unchanged.” High demand for combat aircraft is a key driver behind the need for enhanced munitions options, according to the Mitchell Institute. “The Air Force is currently operating the smallest and oldest aircraft force in its history,” the study reads. “Additionally, current mission capable rates are low and pilots are in increasingly short supply. To best meet combatant command requirements amidst these constraints, it is crucial to ensure each sortie flown and every bomb dropped yields maximum potential.” https://www.airforcetimes.com/news/your-air-force/2019/01/03/new-in-2019-air-force-looks-for-new-bomb-designs-to-fight-russia-and-china

  The military is building a space plane. Now it looks to have an engine up to the task

  By SAMANTHA MASUNAGA A decade after the U.S. Air Force commissioned the next generation of GPS satellites, the first of these spacecraft is finally set to launch into orbit later this year. As with other national security missions, a roughly 200-foot-tall rocket will blast the massive satellite to space, fulfilling a contract worth more than $80 million. But as nations develop technology to disable or shoot down satellites — as China did to one of its own satellites with a ground-based ballistic missile in 2007 — the U.S. military has started to look at options for rapidly and cheaply launching smaller crafts into space. An experimental program spearheaded by a Pentagon research agency could eventually be part of that solution. The Defense Advanced Research Projects Agency, along with aerospace giant Boeing Co., is developing a reusable spaceplane expected to launch small satellites 10 times in 10 days. The vehicle's first test flight is set for 2021, which hints at the Defense Department's growing interest in reusable rocket technology, particularly its potential to drive down launch costs and speed up turnaround time. In recent weeks, the spaceplane's rocket engine, known as the AR-22, completed 10 test fires in 240 hours without need for refurbishments or major repairs, said Jeff Haynes, program manager at Aerojet Rocketdyne. The test firing took place at NASA Stennis Space Center in Mississippi from June 26 to July 6. The engine test is “really good progress,” said Claire Leon, director of Loyola Marymount University's graduate program in systems engineering and former director of the launch enterprise directorate at the U.S. Air Force's Space and Missile Systems Center. “SpaceX has had its success,” she said. “I think this engine test also demonstrates that other companies are doing the technology development and having success that will enable reusability.” The title of first reusable system belongs to NASA's Space Shuttle, though more recently, several commercial space firms, including Microsoft co-founder Paul Allen's Stratolaunch and British billionaire Richard Branson's Virgin Orbit, have developed systems that would reuse aircraft to launch satellites from the belly of a plane. https://www.stripes.com/news/the-military-is-building-a-space-plane-now-it-looks-to-have-an-engine-up-to-the-task-1.538009

  BAE awarded $50.3M for nuclear missile work for U.S., Britain

  ByTauren Dyson Sept. 26 (UPI) -- BAE Systems Technology Solutions and Services has received a new contract for services on the nuclear weapon systems aboard U.S. and British submarines. The $50.3 million contract, the Department of Defense announced Wednesday, covers services on Trident II D5 strategic weapon system programs, submarine guided-missile attack weapons systems, nuclear weapon surety and future concepts for both nations. In early-September, the Navy launched four unarmed test Trident II missiles off the coast of Southern California as part of a Commander Evaluation Test to gauge performance expectation of the Trident II strategic weapon system. The Trident II D5 strategic weapon system is equipped aboard Ohio-class submarines and carries up to 24 missiles. The Polaris Sales Agreement requires the system to be aboard the Vanguard-class submarines used by the U.K. Navy, as well. The Trident missiles have a range of 4,000 nautical miles capable of carrying multiple W76-Mk4/Mk4A or W88-Mk5 reentry bodies. They were initially planned to be phased out of use by 2024 but the system went through a life-extending program to keep them operational through the 2040s. Work under the new contract is expected to be completed by Sept. 30, 2020. https://www.upi.com/Defense-News/2019/09/26/BAE-awarded-503M-for-nuclear-missile-work-for-US-Britain
