  U.S. Navy’s Aircraft Launch Rail Gun Revealed

  Guy Norris Details of the U.S. Navy's new generation, electrically powered aircraft launch and recovery system, currently under test for the first time on the USS Gerald R. Ford (CVN-78) carrier, are visible in a large-scale model at the Singapore Airshow. The Electromagnetic Aircraft Launch System (EMALS) is in development to replace the traditional steam piston catapult launch system on current carriers. The new configuration also includes the electrically powered Advanced Arresting Gear (AAG), which replaces the hydraulic arresting gear in use on the Navy's 10 Nimitz-class aircraft carriers. The EMALS catapult, which is powered by a linear induction motor, is designed to accelerate aircraft more gradually than the steam system and put less stress on the aircraft. The system is also lighter and more flexible than the current design and is capable of launching a wider range of aircraft weights. The AAG is also designed for a broader range of aircraft, including UAVs. The large-scale cutaway model shows the linear induction motors of the EMALs as well as the banks of rotary engines incorporated in the AAG. Fine control of the arresting forces is provided by a large induction motor, which is coupled to energy-absorbing water turbines. Tests on the Ford, the eponymous lead ship of navy's first new class of carriers since the 1970s, are part of efforts to assess the performance of the technology for launch and landing operations. The system has proved more challenging to develop than expected, and improvements are underway to boost reliability for the required sortie generation rate. The service is evaluating aircraft compatibility before the scheduled deployment of the Ford in 2022. https://aviationweek.com/shownews/singapore-airshow/us-navys-aircraft-launch-rail-gun-revealed

  Secretary Wilson to lay out ‘Air Force We Need’ at AFA

  By: Stephen Losey The Air Force has a problem. The military is trying to shift its focus from wars against so-called “violent extremists” in places like Afghanistan, Iraq and Syria so it can prepare for a potential war against a major peer or near-peer nation. But the Air Force is currently too small even for the missions it's being asked to do today in the Middle East, let alone a war against China, Russia or North Korea, said Air Force Secretary Heather Wilson in an Aug. 28 interview at the Pentagon. The service is going to have to grow, she said. But the big question is where — and by how much? Wilson will attempt to answer that question Sept. 17, when she delivers her keynote address, “The Air Force We Need,” at the Air Force Association's Air Space and Cyber Conference. The secretary will lay out how many operational squadrons — such as fighter, bomber, mobility and intelligence, surveillance and reconnaissance — are needed, as well as the matching end strength, for the Air Force to project power and carry out its expected missions in the future. “The chief and I were asked in this last testimony on the Hill for the Defense Authorization Act, ‘Well, what do you need to implement the new National Defense Strategy?” Wilson said. “We should know the answer to that question. That's the work that's been going on the last six months or so.” The Air Force now has 312 operational squadrons, not including squadrons doing support activities such as finance, Wilson said. Squadrons are the basic unit of the Air Force, she said, which is why this new plan will focus on the squadron level. The Air Force intentionally didn't consider budgets as it drew up this plan over the past six months, Wilson said. Instead, it focused on what would be required to fight a major war. With that information in hand, she said, the Air Force can better articulate where it's headed — and what the potential risks might be of not funding or underfunding certain elements.

  Brazil postpones decisions again for its new corvettes

  Victor Barreira, Istanbul - IHS Jane's Defence Weekly The Brazilian Navy has postponed by about two months the short list and best and final offer (BAFO) decisions for its ambitious Tamandaré-class corvette project, the second leading priority within the force. The newly established schedule calls for the short list and BAFO announcements to occur in October and December respectively, the navy told Jane's on 17 August. The navy said it is delaying its decision because it needs additional information from the competitors to properly analyse the bids. Service officials provided no additional details on what information it still requires. The navy has not said how many companies will be included on the short list.
