  The US Air Force wants to develop a hypersonic cruise missile

  By: Valerie Insinna WASHINGTON — The U.S. Air Force is seeking information from industry about hypersonic cruise missile technology, with the hopes of starting up a new prototyping program in the near future. The service issued a sources sought notification on April 27 asking companies to submit information about air-breathing conventional hypersonic cruise missiles that could be launched from fighter jets and bombers. The responses will help the Air Force determine whether to begin funding a new program of record and figure out how quickly it will be able to field the new weapon, said Air Force acquisition executive Will Roper. “In the case of how fast we could go with the scramjet technology getting into cruise missile and missionizing it, I think we can go fast,” he told reporters April 30. “I don't know how fast — that's why we're reaching out to the street. But given how far scramjet technology has matured, I'd expect that we'll be able to go pretty quickly on this.” According to the solicitation, the service would aim to conduct a preliminary design review in the fourth quarter of fiscal 2021. The technologies offered should feature ramjet, scramjet or dual-mode propulsion — a major difference from the hypersonic weapons currently under development by the Defense Department, which are all boost glide missiles. There are multiple advantages to fielding air-breathing and boost glide hypersonic weapons, Roper said. Boost glide missiles fly just below space, above the “thick atmosphere” where scramjet missiles would fly. That allows scramjet missiles to take on certain missions and targets that boost-glide systems cannot engage. “In the world of competing technology, we can't afford to have any blind spots or cede any ground. So we're preparing to make sure we don't cede ground on scramjet technology and hypersonic cruise missiles as a whole,” Roper said. “We will have greater flexibility with this as a whole. That's one reason we're interested in accelerating the technology. It's mature, it's ready. It will give our operators greater flexibility.” It will also allow the Defense Department to diversify the number of companies that can produce hypersonic weapons, he said. “In the case of boost glide technology, a lot of our major programs in the department go to the same suppliers,” in part because those companies have pioneered materials and components that have not been replicated throughout industry, Roper said. “One of the reasons I'm excited about starting a hypersonic cruise missile program is that we will have different suppliers. It's a very different technology.” Roper said the hypersonic cruise missile effort would involve inputs from the Air Force Research Laboratory and the Defense Advanced Research Projects Agency. In particular, DARPA's Hypersonic Air-breathing Weapon Concept, or HAWC, effort could inform the new program. As part of the effort, a Raytheon-Northrop Grumman team and a Lockheed Martin-Aerojet Rocketdyne team are building scramjet-powered hypersonic vehicles. “Scramjet technology has come a long way. I have been exceptionally impressed by what new manufacturing techniques are enabling,” Roper said. “I entered this job thinking scramjet will probably be a step behind boost glide. I am delighted to say that I was wrong. Scramjet is much more mature and ready to go than I originally thought.” The Air Force may be embarking on a new hypersonic weapons program just months after canceling one of its two development efforts, the Hypersonic Conventional Strike Weapon, or HCSW. Although HCSW showed promise and was on track for flight tests, the service killed it the fiscal 2021 budget rollout this February in favor of the Air-Launched Rapid Response Weapon. Both ARRW and HCSW are boost-glide weapons made by Lockheed, but the Air Force decided to pursue ARRW because it was more affordable and could be carried in larger quantities by the B-52 and F-15 aircraft, Roper said. https://www.defensenews.com/industry/techwatch/2020/04/30/the-air-force-wants-to-develop-a-hypersonic-cruise-missile/

  How U.S. Open Skies Exit Could Undermine Arms Control

  Tony Osborne Jen DiMascio May 28, 2020 The decision by the U.S. government to withdraw from the Open Skies Treaty signed two decades ago is creating ripples of discontent within the U.S. and in Europe. Washington announced on May 22 that it would end its obligations to the arms control treaty in six months, saying that it was “no longer in the United States' best interest to remain a party to this Treaty when Russia does not uphold its commitments,” in a statement put out by the Defense Department. The Open Skies Treaty permits its 34 signatories to conduct observation flights over each other's territory. Aircraft with four types of sensors—-optical panoramic and framing cameras, real-time video cameras, infrared line-scanners and sideways-looking synthetic aperture radar—may make observations anywhere over a country's national territory. Treaty rules say that the flight may only be restricted for reasons of flight safety, not for reasons of national security. NATO and European nations may share U.S. concerns about inconsistent flight restrictions imposed by Moscow but see a U.S. departure from the agreement, in place since 1992, as regrettable. According to the U.S. and NATO, Russia has imposed restrictions on the treaty, in particular those flying near Kaliningrad, Russia's enclave on the Baltic Sea, and near the country's border with Georgia. The Pentagon also says Moscow blocked the overflight of a major military exercise in September 2019, “preventing the exact transparency the treaty is meant to provide.” In an op-ed in The New York Times, Tim Morrison, a senior fellow at the Hudson Institute and a former member of this administration's National Security Council, added that Russia has been using its overflights to collect “military relevant intelligence on the other parties, like the means to target critical infrastructure.” NATO Secretary General Jens Stoltenberg, during the May 22 meeting of alliance members, called on the Russian government to return to compliance as soon as possible, noting that the U.S. could reconsider its position if Russia complied. European Open Skies Treaty member states—including Belgium, the Czech Republic, Finland, France, Germany, Italy, Luxembourg, Netherlands, Spain and Sweden—said they would continue to implement the treaty, saying it has a “clear added value” for conventional arms control architecture and cooperative security. Russia rejects the claims of flight restrictions and contends that the U.S. had limited Russia's own Open Skies flights over Hawaii and the Aleutian Islands. Senior Russian officials, including Dmitry Medvedev, deputy chairman of the Russian Security Council, denounced Washington's decision. Medvedev said the U.S. had taken another step down the “path of dismantling the international security architecture that took decades to lay down.” Moscow believes Washington's decision could also affect other arms control treaties, with negotiations on the next New Strategic Arms Reduction Treaty potentially at risk. In Washington, the leaders of the House Armed Services and Foreign Affairs committees (both Democrats) have written a letter to Defense Secretary Mark Esper and Secretary of State Mike Pompeo contending that withdrawal from the treaty is illegal. They say it violates the fiscal 2020 National Defense Authorization Act, which requires Esper and Pompeo to notify Congress 120 days before the intent to withdrawal is presented. “This notification must be based on your joint conclusion that withdrawal is in the best interests of the United States and that other states parties to the treaty have been consulted. To date, this requirement has not been fulfilled,” wrote Reps. Adam Smith (Wash.), the Armed Services chairman, and Eliot Engel (N.Y.), the Foreign Affairs chairman. President Donald Trump and his administration have support from Repub-licans who lead the Senate for their decision to exit the treaty. Sen. James Inhofe (R-Okla.), who chairs the Senate Armed Services Committee, asserts that the U.S. should withdraw if Russia is not complying with the agreement. “It will be critical for the Trump administration to continue working with our allies and partners, especially those in Eastern Europe, to ensure they have access to the intelligence they need to protect their security. That includes facilitating access to high-quality imagery.” The U.S. had planned to upgrade the two Boeing OC-135 aircraft delivered to the Air Force in 1996. Late last year, the U.S. issued a request for information saying it was considering awarding two contracts—one for the purchase of two commercial aircraft and another to modify the airframe and provide logistics support. But the Pentagon did not include funding for OC-135 upgrades in its fiscal 2020 budget request. And in March, Esper told Congress he was not prepared to authorize funding for those upgrades until a path forward is clear. Several signatories to the treaty have dedicated aircraft for the mission; others share or lease platforms from other nations for the task. Germany is the latest country to dedicate an aircraft for the mission, using an Airbus A319 converted by Lufthansa Technik. https://aviationweek.com/defense-space/budget-policy-operations/how-us-open-skies-exit-could-undermine-arms-control
