    'Excellent New Year's gift': Putin boasts after testing 'invulnerable' Russian hypersonic missile

    The Kremlin said the Avangard missile successfully hit a designated practice target 6,000 kilometres away from its launch site The Associated Press , Vladimir Isachenkov MOSCOW — Russian President Vladimir Putin oversaw a test Wednesday of a new hypersonic glide vehicle, declaring that the weapon is impossible to intercept and will ensure Russia's security for decades to come. Speaking to Russia's top military brass after watching the live feed of the launch of the Avangard vehicle from the Defence Ministry's control room, Putin said the successful test was a “great success” and an “excellent New Year's gift to the nation.” The test comes amid bitter tensions in Russia-U.S. relations, which have sunk to their lowest level since the Cold War times over the conflict in Ukraine, the war in Syria and the allegations of Russian meddling in the 2016 U.S. presidential election. Putin's hopes for repairing ties with Washington under President Donald Trump have fizzled amid investigations into allegations of Trump's campaign ties with Russia, and tensions have escalated as the U.S. administration slapped Russia with new waves of sanctions. The Avangard was among the array of new nuclear weapons that Putin presented in March, saying that Russia had to develop them in response to the development of the U.S. missile defence system that could erode Russia's nuclear deterrent. In Wednesday's test, the weapon was launched from the Dombarovskiy missile base in the southern Ural Mountains. The Kremlin said it successfully hit a designated practice target on the Kura shooting range on Kamchatka, 6,000 kilometres away. “The Avangard is invulnerable to intercept by any existing and prospective missile defence means of the potential adversary,” Putin said after the test, adding that the new weapon will enter service next year with the military's Strategic Missile Forces. When first presenting the Avangard in March, the Russian leader said the new system has an intercontinental range and can fly in the atmosphere at 20 times the speed of sound, bypassing the enemy's missile defence. He emphasized that no other country currently has hypersonic weapons. Putin has said that Avangard is designed using new composite materials to withstand temperatures of up to 2,000 degrees Celsius (3,632 degrees Fahrenheit) that come from a flight through the atmosphere at hypersonic speeds. https://nationalpost.com/news/world/russias-putin-oversees-test-of-hypersonic-weapon

  • For US Air Force pilots, the toughest training flights are going virtual

    For US Air Force pilots, the toughest training flights are going virtual

    By: Valerie Insinna NELLIS AIR FORCE BASE, Nev. — A new simulator campus at Nellis Air Force Base could be key for the U.S. Air Force as it grapples with the question of how it can train pilots against complex threats like Russia and China at a budget-friendly cost. On Aug. 17, the Air Force opened the doors of the Virtual Test and Training Center, or VTTC, a new, $38 million building where pilots will practice advanced tactics in a simulated environment that replicates war against a near-peer nation. “When you think about great power competition and where we might have to fight — shipping out to fight a China or Russia, particularly — there is no live training venue for the joint force, certainly for the Air Force, that's big enough, that has the threat density that can replicate what China or Russia can do,” said Maj. Gen. Chuck Corcoran, who leads the U.S. Air Force Warfare Center at Nellis. While live exercises will remain an important component of pilot training, the VTTC will give the Air Force a way to simulate a vast battlespace populated by high-end threats. Users will be able to network with other pilots on the system — who fly F-16s, F-22s, F-35s and F-15Es, with perhaps more to come — and fly complex missions against virtual enemies that are impossible to emulate in live training exercises like Red Flag. The VTTC building, which Defense News toured during an Aug. 21 visit to the base, is currently empty. But it won't stay that way for long, said Lt. Col. Chris Duncan, an F-35 operational test pilot and commander of Detachment 1, 29th Training Systems Squadron. F-15E Strike Eagle simulators are slated to be delivered to the center in October and will go online in April 2021. The joint simulation environment — a government-owned virtual training environment currently under development at Naval Air Station Patuxent River, Maryland, and when finished will emulate high-end threats — is set to be fielded at the VTTC in October 2021. “Typically aircraft simulators have taught pilots how to fly them and basic employment,” Duncan said. “We're not worried about those things. We're assuming they already know that.” Instead, the training will focus on more robust mission sets, including advanced training for Air Force Weapons School students, operational testing of new platforms and large-scale war games, he said. The Air Force is deliberating how best it can expand the VTTC's capabilities over time on a limited budget. Among the factors under consideration is whether to buy additional simulators, such as ones for the new F-15EX. It may roll out the Nellis Mission Operations Network, on which the VTTC will run, to other bases such as Whitman Air Force Base in Missouri — the home to the service's only stealth bomber. There is also discussion about how to integrate the simulators on the network with live aircraft flying on the Nevada Test and Training Range, which would allow the VTTC to project synthetic threats to jets practicing midair tactics. Historically, the Air Force has been hard-pressed to fund advanced simulation efforts. The ultimate success of the VTTC may ultimately come down to whether there is enough money to continue funding simulators for additional aircraft and to keep upgrading hardware and software. Duncan said the Air Force is already keeping that point in mind. Instead of simulators that provide a completely accurate cockpit experience, the service is looking to save money by prioritizing simulators that can provide the experience of advanced missions, even if the simulator imagery or cockpit experience isn't completely realistic. But he underscored the cost-effectiveness of virtual training when compared to its live counterpart. “The payoff, the bang for the buck,” Duncan said, “it far surpasses what we can do in live flying.” https://www.defensenews.com/air/2020/08/25/for-air-force-pilots-the-toughest-training-flights-are-going-virtual/

  • The F-35 jet might hit full-rate production more than a year late

    The F-35 jet might hit full-rate production more than a year late

    By: Valerie Insinna WASHINGTON — The U.S. Defense Department will not clear the F-35 fighter jet for full-rate production this year, and it may even have to push that milestone as far as January 2021, the Pentagon's acquisition executive said Friday. The Pentagon had intended to make a full-rate production decision — also known as Milestone C — by the end of 2019. But because the Joint Simulation Environment continues to face delays in its own development, the Defense Department will have to defer that milestone by as many as 13 months, Under Secretary of Defense for Acquisition and Sustainment Ellen Lord told reporters during a news conference. The Joint Simulation Environment, or JSE, is needed to conduct simulated evaluations of the F-35 in a range of high-threat scenarios. “We actually had signed out of the JPO [F-35 Joint Program Office] earlier this week a program deviation report that documented expected schedule threshold breach in the Milestone C full-rate production decision of up to 13 months,” Lord said. It is unclear whether the delay will cause an increase in program costs. Although the Defense Department already buys the F-35 in large numbers, the full-rate production decision is viewed as a major show of confidence in the program's maturity. During this time, the yearly production rate is set to skyrocket from the 91 jets manufactured by Lockheed Martin in 2018 to upward of 160 by 2023. But before Lord signs off on the production decision, the F-35 must complete operational testing, the results of which will be validated by Robert Behler, the Pentagon's director of operational test and evaluation. The F-35's testing community intended to complete initial operational test and evaluation, or IOT&E, by this summer; however, the JSE is not yet complete. “We are not making as quick progress on the Joint Simulation Environment, integrating the F-35 into it. It is a critical portion of IOT&E. We work closely with Dr. Behler and DOT&E [[the office of the director of operational test and evaluation]. They are making excellent progress out on the range with the F-35, but we need to do the work in the Joint Simulation Environment,” Lord said. “We have collectively decided that we need the JSE [to be] absolutely correct before we proceed, so I will make some decisions about when that full-rate production decision will be made shortly," she added. Specifically, the Defense Department and F-35 prime contractor Lockheed Martin are lagging behind in integrating the "'F-35 In-A-Box” — the simulated model of the F-35 and its sensors and weapons — into the JSE, reported Military.com, which broke the news of the testing delay in September. Even before IO&TE formally started, the F-35 test community had noted the challenge of maintaining the planned schedule. The F-35 began operational tests in December 2018, three months after the originally scheduled start date in September. The program office maintained that its goal was to see the test phase finished by the summer of 2019. However, F-35 test director Air Force Col. Varun Puri documented concerns in a September 2018 presentation that the test phase could slip until September 2019, which could add budget pressure to the program. In a statement, Lockheed Martin expressed confidence in its ability to ramp up production over the next few years. “As Secretary Lord stated earlier today, the F-35 is performing exceptionally well for our customers and we continue to ramp up production, modernize the aircraft and improve sustainment performance,” the company said. “This year our goal is to deliver 131 aircraft and that is on track to grow to over 140 production aircraft deliveries next year. We are confident the full F-35 enterprise is prepared for full rate production and ready to meet growing customer demand.” https://www.defensenews.com/air/2019/10/18/the-f-35-may-hit-full-rate-production-more-than-a-year-late/
