  New Images Of The Tempest Sixth-Generation Aircraft Revealed During UK Industry Engagement Event

  Development for the new Tempest sixth-generation fighter is moving on with some revolutionary concepts. Team Tempest and the Royal Air Force recently held a virtual event to provide an update about the development opportunities of the new sixth generation aircraft to industry and government representatives from Northern Ireland, the first of a series of events to engage with industries across the UK. Within the press release there is also some new renderings of the aircraft which, we have to note, is not in its final shape as it's being designed “from the inside out” and the airframe's exterior design may change to reflect changes in the internal systems. According to the press release, “Delegates heard from Air Chief Marshal Sir Michael Wigston and other RAF senior leaders who highlighted how Team Tempest is taking a revolutionary approach to partnership, engaging with a wide range of leading companies, SMEs and academia to bring leading innovators into the endeavour and ensure the UK remains at the leading edge of Combat Air systems development. The RAF Capability leadership team highlighted updates in emerging strategy and identified examples of innovation and future opportunities. Key members from the Team Tempest industry partner community also provided attendees with updates on the programme and explained how Tempest is working in radical ways to develop world-leading capability, with a focus on affordability and efficiency.” Team Tempest is currently made of the core industry partners BAE Systems, Rolls Royce, Leonardo UK and MBDA UK, which were joined last year by Leonardo Italy, Elettronica, Avio Aero, MBDA Italy, Saab and GKN Aerospace Sweden and, more recently, by Thales UK, Bombardier Belfast, Collins Aerospace, GE Aviation UK, GKN Aerospace, Martin Baker and QinetiQ. A widespread industry participation is considered essential for the programme to bring the best expertise to work on the more than 60 technology demonstrations which are currently in progress. According to a statement shared by the UK Ministry of Defence and the core industry partners, “Tempest is one of the UK's most ambitious technological endeavours and designed to deliver a highly advanced, adaptable combat air system to come into service from the mid-2030s. This next generation combat aircraft, which forms part of a wider combat air system, will exploit new technologies as they evolve to respond to the changing nature of the battlespace, addressing increasingly high-tech and complex threats and conflict.” Back in October, engineers working on the project revealed some of the highly innovative systems that are being developed for Tempest as part of the Future Combat Air System Technology Initiative (FCAS TI) programme. Here is what has been disclosed to the public so far. Leonardo, which is the project lead for electronics, is developing a new radar technology called Multi-Function Radar Frequency System. The new sensor will reportedly collect and process 10'000 times more data than existing systems, or “equivalent to the internet traffic of a large city every second”, providing the operators with a clear view of the battlespace and of potential targets. According to the company, complete sub-systems have already been built and successfully tested, paving the way eventually to future airborne testing. BAE Systems if working on another revolutionary concept, the “wearable cockpit”. In this case, the cockpit as we know it, full of switches, gauges and screens, becomes completely digital and all physical controls are replaced by Augmented and Virtual Reality systems. The new cockpit would be projected inside the pilot's helmet and completely customizable according to the pilot's preference and mission's needs. As human-AI teaming, a virtual copilot is being developed to interact with the pilot and provide support during the flight. “Psycho-physiological” technologies are also being trialed to study the operator's physical and cognitive processes to better understand increasing exertion, stress, workload and fatigue. According to the company, some of these technologies are being tested controlled test flight conditions aboard the Typhoon to inform further development. MBDA UK is also working on the wearable cockpit concept to integrate weapons systems information and operations. Rolls-Royce is working on the advanced combustion system technology that will power Tempest. The next-generation system is being designed to be hotter than previous ones to increase the efficiency of the engine, its range and speed, while reducing carbon dioxide emissions. Together with the higher-temperature combustion, there will be a new thermal management system that will use the turbine as a heat sink to recycle thermal energy, removing the need for overboard venting and improving the efficiency, and an increased electrical power production, reportedly in the order of one megawatt, that will be used to power all the aircraft's subsystems. This follows the assessment by Rolls Royce that future fighter aircraft will have unprecedented levels of electrical power demand and thermal load that need to be managed accordingly to maintain the airframe's low observability. Being more specific, the company stated that they will integrate an Electrical Embedded Starter Generator that will function both as an APU and as an electrical generator after the engine is spooled up. The Tempest is expected to have also his own loyal wingman, currently being developed as the Lightweight Affordable Novel Combat Aircraft (LANCA) concept. According to the MoD, LANCA will offer “increased protection, survivability and information for the manned aircraft – and could even provide an unmanned combat air ‘fleet' in the future.” A demonstration project, called “Moquito” and comparable to the Skyborg program of the U.S. Air Force, is currently in its first phase of evaluation. Three teams, Boeing Defence UK, Team Avenger (led by Blue Bear Systems Research), and Team Blackdawn (Callen-Lenz, Bombardier Belfast and Northrop Grumman UK), submitted designs for the flight demonstrations phase, which could begin in 2022-2023, after two finalists are selected during second phase of evaluation. LANCA will reportedly be a transonic aircraft costing one-tenth of a fighter aircraft, able to employ multi-role sensors, Electronic Warfare suites and both air-to-air and air-to-surface weapons. The unmanned aircraft project, led by the RAF Rapid Capabilities Office and the Defence Science and Technology Laboratory, originated in 2015, three years before the Tempest announcement. While a timeline for its entry into service has not been disclosed, the LANCA may be first deployed alongside the Typhoon and the F-35, before the entry into service of the new Tempest in 2035. https://theaviationist.com/2020/12/09/new-images-of-the-tempest-sixth-generation-aircraft-revealed-during-uk-industry-engagement-event/

  Destroyers Maxed Out, Navy Looks To New Hulls: Power For Radars & Lasers

  By SYDNEY J. FREEDBERG JR. ARLINGTON: The Navy has crammed as much electronics as it can into its new DDG-51 Flight III destroyers now beginning construction, Rear Adm. William Galinis said this morning. That drives the service towards a new Large Surface Combatant that can comfortably accommodate the same high-powered radars, as well as future weapons such as lasers, on either a modified DDG-51 hull or an entirely new design. “It's going to be more of an evolutionary approach as we migrate from the DDG-51 Flight IIIs to the Large Surface Combatant,” said Galinis, the Navy's Program Executive Officer for Ships. (LSC evolved from the Future Surface Combatant concept and will serve along a new frigate and unmanned surface vessels). “(We) start with a DDG-51 flight III combat system and we build off of that, probably bringing in a new HME (Hull, Mechanical, & Engineering) infrastructure, a new power architecture, to support that system as it then evolves going forward.” “Before the end of the year, we'll start reaching out to industry to start sharing some of the thoughts we have and where we think we're going,” Galinis told a Navy League breakfast audience. “We'll bring industry into this at the right point, but we're still kind of working a lot of the technology pieces and what the requirements are right now.” Evolution, Not Revolution This evolutionary approach is similar to how the current Aegis combat system entered service on the CG-47 Ticonderoga cruisers in 1983 but came into its own on the DDG-51 Arleigh Burke destroyers. (Despite the difference in names, the two classes are virtually the same size). The DDG-51 is now the single most common type in the fleet, a vital part of the hoped-for 355-ship Navy, with some ships expected to serve into the 2070s: There are now 64 Arleigh Burkes of various sub-types in service; nine of the latest Flight IIA variant are in various stages of construction; and work is beginning on the new Flight IIIs in Mississippi (Huntington Ingalls Industries) and Maine (General Dynamics-owned Bath Iron Works). The Navy is doubling down on long-standing programs to keep its older warships up to date and on par with the newest versions. But the current destroyers just won't be able to keep up with the Flight III, which will have a slightly modified hull and higher-voltage electricity to accommodate Raytheon's massive new Air & Missile Defense Radar. A stripped down version of the AMDR, the Enterprise Air Search Radar (EASR, also by Raytheon) is already going on amphibious ships and might just fit on older Burkes as well, however. But it's tight. On the Flight III, even with the hull modifications, “you kind of get to the naval architectural limits of the DDG-51 hullform,” Galinis told a Navy League breakfast this morning. “That's going to bring a lot of incredible capabilities to the fleet but there's also a fair amount of technical risk.” The Navy is laboring mightily to reduce that risk on Flight III with simulations and land-based testing, including a full prototype of the new power plant being built in Philadelphia. But it's clear the combat system is out of room to grow within the limits of the current hull. So how different does the next ship need to be? “How much more combat capability can we squeeze into the current hullform?” Galinis said. “Do we use the DDG-51 hullform and maybe expand that? Do we build a new hullform?” “We're looking at all the options, Sydney,” he said when reporters clustered around him after his talk. “(It's in) very, very early stages... to say it'll be one system over another or one power architecture over another, it's way too early.” “We're still working through what that power architecture looks like,” Galinis told the breakfast. “Do we stay with a more traditional (gas-driven) system... or do we really make that transition to an integrated electric plant — and at some point, probably, bring in energy storage magazines...to support directed energy weapons and things like that?” The admiral's referring here to anti-missile lasers, railguns, and other high-tech but electricity-hungry systems. Having field-tested a rather jury-rigged 30 kilowatt laseron the converted amphibious ship Ponce, the Navy's next step is a more permanent, properly integrated installation next year on an amphibious ship, LPD-27 Portland. (Subsequent LPDs won't have the laser under current plans). But Portland is part of the relatively roomy LPD-17 San Antonio class, which has plenty of space, weight capacity, power, and cooling capacity (SWAP-C) available, in large part because the Navy never installed a planned 16 Vertical Launch System (VLS) tubes in the bow. By contrast, while the Navy's studying how to fit a laser on the Arleigh Burkes, the space and electricity available are much tighter. The DDG-1000 Digression The larger DDG-1000 Zumwalt class does have integrated electric drive that's performing well in sea trials, Galinis said. (That said, the brand-new DDG-1001, Michael Monsoor, has had glitches with the harmonic filter that manages the power and, more recently, with its turbine engine blades). “We've learned a lot from DDG-1000” that the Navy's now applying both to its highest priority program, the Columbia-class nuclear missile submarine, and potentially to the future Large Surface Combatant as well. In other ways, DDG-1000 is a dead end, too large and expensive for the Navy to afford in quantity. The Navy truncated the class to just three ships and restarted Arleigh Burke production, which it had halted on the assumption the Zumwalts would be built in bulk. Today, the Zumwalt‘s very mission is in doubt. The ship was designed around a 155 mm gun with revolutionary rocket-boosted shells, but ammunition technology hasn't reached the ranges the Navy wanted for the original mission of bombarding targets ashore. With the resurgence of the Russian fleet and the rise of China's, the Navy now wants to turn the DDG-1000s into ship-killers, which requires even longer ranges because modern naval battle is a duel of missiles. The gun's place in ship-to-ship combat is “probably not a significant role, at least not at the ranges we're interested in,” Galinis told reporters. While the Navy could invest in long-range cannon ammunition, he said, it's paused work on several potential shells it test-fired last summer, awaiting the final mission review. If the Zumwalts do move to the anti-ship mission, which Galinis said they would be well suited for with minor modifications, their guns will be less relevant than their 80 Advanced VLS missile tubes or future weapons such as railguns drawing on their prodigious electric power. That power plant might evolve into the electric heart of the future Large Surface Combatant — or it might not. “We're going to have the requirements discussion with Navy leadership and then we're going to want to engage industry as we start thinking about what options might be available,” Galinis said. “Frankly industry's probably best suited to try to help us with the technology piece, especially if we start thinking (that) we want an innovative electric plant.....We'd go to probably the big power electronics/power system vendors, who really work in that field and have the best information on where technology's going.” https://breakingdefense.com/2018/07/destroyers-maxed-out-navy-looks-to-new-hulls-power-for-radars-lasers/
