DARPA chooses three firms to design nuclear-powered space vehicle

DARPA believes nuclear-powered propulsion could enable rapid maneuver in space — a capability that is difficult to achieve with current electric and chemical propulsion systems.

    Cyber innovation at the forefront of UK’s approach to modern warfare

    Defence Secretary Penny Mordaunt has announced £22 million in funding for Army cyber operations centres Speaking this evening at the NATO Cyber Defence Pledge Conference in London, Defence Secretary Penny Mordaunt will address the need for the UK and NATO members to recognise offensive cyber as central to modern warfare. As the UK has already demonstrated against Daesh in the Middle East, it can be a vital tool to keep people in the UK and overseas safe from virtual and physical threats. The military continues to develop its cyber capabilities as part of the £1.9 billion investment into the National Cyber Security Strategy, focused on boosting the UK's cyber security. Recent UK innovations have included the creation of the National Cyber Security Centre which brings together government, intelligence agencies and the private sector into one organisation. The state-of-the-art Defence Cyber School, which marked its first anniversary in March this year, is also training the next generation of cyber experts. The Defence Secretary will today expand that commitment, announcing £22 million in funding to stand up new Army cyber operations centres across the UK. Defence Secretary Penny Mordaunt will say: We know all about the dangers. Whether the attacks come from Russia, China or North Korea. Whether they come from hacktivists, criminals or extremists. Whether its malware or fake news. Cyber can bring down our national infrastructure and undermine our democracy. It's time to pay more than lip service to cyber. We must convince our adversaries their advances simply aren't worth the cost. Cyber enemies think they can act with impunity. We must show them they can't. That we are ready to respond at a time and place of our choosing in any domain, not just the virtual world. We need coherent cyber offense as well as defence. So today I can announce we will be investing £22m to create new cyber operations centres. Putting the Army at the forefront of information warfare, the centres will draw together cyber capability from a range of sources – including both national intelligence and open source data – to give the Army the competitive edge across all environments. The cyber centres will provide the Army with 24/7 information and analysis, dispel misinformation and give the UK Armed Forces and our allies the upper hand on emerging digital threats. The centres are likely to be used to support overseas operations, humanitarian missions, and efforts to protect UK digital communications on home soil. The centres will work with existing Army capabilities, such as 77 Brigade – a modern and information-focused British Army unit – but will also have regular contact with joint and other national security organisations. Major General Tom Copinger-Symes, General Officer Commanding Force Troops Command: These new cyber centres will allow the Army and Defence to transform the way we use data, at speed, so that we can compete with our adversaries in a way fit for the 21st Century. Combining artificial intelligence with our military analysts will help us better understand threats and exploit opportunities, in turn enabling us to get the truth out much more rapidly, quashing the noise of disinformation from our enemies. While details on locations are yet to be confirmed, building in support of the centres is due to begin next year, with operations expected to commence in the early 2020s. The MOD is embracing transformation at an ever-faster rate and investments in truly high-tech innovation, such as in the provision of cutting-edge cyber centres, that will develop the Armed Forces of the future. https://www.gov.uk/government/news/cyber-innovation-at-the-forefront-of-uks-approach-to-modern-warfare

    Italy was committed to fund its share of the Italian-Anglo-Japanese fighter jet programme for 15 years, long enough for the aircraft to enter service, the director for the project at the Italian Ministry of Defence said on Wednesday.

    General Electric wins $517 million contract to build engines for Army’s next generation helicopters

    By: Valerie Insinna WASHINGTON — General Electric Aviation beat the Advanced Turbine Engine Company — a Honeywell and Pratt & Whitney team — to win the $517 million award for the engineering, manufacturing and development phase of the Improved Turbine Engine Program, or ITEP. “We are honored to be chosen by the Army to continue powering their Black Hawks and Apaches for decades to come,” said Tony Mathis, president and CEO of GE Aviation's military business. “We've invested the resources and infrastructure to execute immediately, and our team is ready to get to work on delivering the improved capabilities of the T901 to the warfighter.” The fierce competition started more than a decade ago, and its outcome will influence Army rotorcraft for decades to come. GE's T901 engine is now set to replace the T700 used by the Army's legacy utility and attack helicopters, but could also potentially outfit the Army's next generation reconnaissance helicopter in the Future Vertical Lift family of systems. “The requirements documents for the [Future Attack Reconnaissance Aircraft] specifiesTHE ITEP engine. It has got the FVL stamp of approval,” Jim Thomson, Jr., acting deputy director for the Army's future vertical lift cross functional team, told Defense News in a recent interview. ITEP answers a number of problems that emerged as the Army operated Apaches and Black Hawks during combat in Afghanistan and Iraq. The AH-64 and UH-60 became heavier as the service added armor and other upgrades during wartime, and they flew in hotter conditions and higher altitudes than would normally be optimal. “The helicopters were originally designed to work at 4,000 feet on a 95-degree day, and they were flying them much higher than that,” Mike Sousa, GE's business development leader for advanced turboshaft engines, told Defense News in December 2018. “When you do that, you just don't have as much power from the engine.” The Army's requirements for ITEP were clear throughout the process: Design a 3,000 shaft horsepower engine that reduces fuel consumption by 25 percent and increases its service life by 20 percent compared to the T700, a 2,000 shaft horsepower engine. Both companies were awarded risk reduction contracts in August 2016, with ATEC getting $154 million and GE Aviation getting $102 million to further refine their designs. Both companies had already spent years conceptualizing new engines and developing novel tech. GE, the incumbent manufacturer of the T700, offered a single spool engine. Sousa said that configuration would help the company meet weight requirements while removing cost and complexity from the design. “Our fundamental approach there was how do we keep this engine as affordable as possible and as low weight as possible,” he told Defense News in 2018. “Helicopters are unique in that they fly into very dirty environments, very austere environments, unprepared landing strips, unprepared surfaces,” added Ron Hutter, GE's executive director of the T901 program. “They generate a lot of dust. You really want to look at the simplicity of the architecture in terms of maintainability. That's another aspect that drove us to stick with the single-spool configuration.” GE estimates that it's spent $9 billion in testing technologies relevant to the T901. ATEC had proposed a double spool engine it dubbed the T900. “We were disappointed to learn that the U.S. Army did not select our offering,” said Craig Madden, president of ATEC. “We believe that we offered the most advanced, capable and lowest risk engine for ITEP for the Army to improve the overall performance of its Apache and Black Hawk fleets.” https://www.defensenews.com/air/2019/02/02/general-electric-wins-517-million-contract-to-build-engines-for-armys-next-generation-helicopters
