    Germany’s fighter jet race could start dropping bidders this summer

    By: Sebastian Sprenger COLOGNE, Germany ― A multibillion dollar program to replace the German military's Tornado aircraft is nearing another round of decisions that could narrow the field of bidders. The due date for a “quality gate” review, as the wide-ranging analysis is called in Bundeswehr jargon, has been on the calendar for this month. But officials now say the exercise could last through the summer. The discussions are principally about realizing an extended service life for the 1970s-era Tornados, though exactly by how long remains to be seen. Closely linked to that question is an examination of what potential follow-on aircraft are best suited to pick up the legacy planes' roles in a variety of life-span scenarios. Officials emphasize that no decision has been made on who will build the new planes to replace roughly 90 Tornados. A formal competition is expected to begin later this year or early 2019 among those aircraft types still deemed suitable by the government at that time. In the running is the Eurofigher Typhoon, Lockheed Martin's F-35, and Boeing's F-15 and F-18. The Typhoon is made by a European consortium of Airbus, Leonardo and BAE Systems. Defence Ministry officials have said they prefer the Eurofighter option, arguing that keeping the European aircraft industry busy will be key in strengthening the continent's defense capabilities. That goes especially for the Franco-German alliance in charge of developing a combat-capable aerial drone and, later, a sixth-generation Future Combat Air System. Some in the Luftwaffe, the German air force, are rooting for the F-35. The affinity partly stems from personnel exchanges with the U.S. Air Force, giving German pilots some exposure to the marquee American defense program. All companies delivered their formal offers to the Defence Ministry in April, coinciding with the ILA Berlin air show. Lockheed Martin staged a sizable promotional showing at the event for its F-35, mixing promises about the jet's advanced capabilities with a professed obliviousness to the political minefield of Europe's economic powerhouse that is Germany weighing a U.S. aircraft at this time. As German analysts continue to crunch the numbers on the Tornado-replacement effort, Reuters reported this week that Berlin requested information from the Pentagon in April about what it would take to certify the Eurofighter to deliver nuclear weapons. NATO policies for nuclear burden-sharing dictate that German pilots will carry American atomic bombs in case of a war on the continent. The Luftwaffe has set aside a number of Tornados for that purpose, and any follow-on aircraft will have to be configured to carry out the mission. While the Pentagon has no say over which jet Germany will eventually pick, officials in Washington must approve the integration of American nuclear bombs on the aircraft. Citing sources on both sides of the Atlantic, Reuters reported that the process could take up to 10 years and that the F-35 was in line for the nuclear weapons integration before the Eurofighter would be considered. A wait time of seven years could conflict with Berlin's plan to begin phasing out Tornados starting in 2025. But according to officials, that's where the fine-tuning of the “quality gate” could come into play, making it possible to alter the timing accordingly. “We are confident that Eurofighter Typhoon can deliver all the capabilities the German Air Force requires and perform all the roles that are currently performed on Tornado for Germany,” a Eurofighter spokesman said. “This of course includes the nuclear role.” https://www.defensenews.com/global/europe/2018/06/21/germanys-fighter-jet-race-could-start-dropping-bidders-this-summer/

    Queen Liz: Behind the scenes on Britain’s newest aircraft carrier

    by Matt Haskell The British Royal Navy's largest ever warship and newest aircraft carrier, HMS Queen Elizabeth, arrived in Halifax, N.S., on Sept. 12 as part of an historic tour of Canada and the United States The ship is currently participating in a joint three-month exercise to facilitate the arrival of the first British-owned F-35B Lightning II fighter jets, which have short takeoff/vertical landing capability. On Oct. 17, Skies embarked on the state-of-the-art ship in Atlantic waters, just off the Florida coast, for a behind-the-Fscenes view of the historic events. The exercise, dubbed WESTLANT 2019, saw Queen Liz (as she is lovingly referred to by those who sail her) joined by her fellow ships HMS Dragon, HMS Northumberland, and RFA Tideforce, together forming a cohesive Carrier Strike Group. The exercise aims to simulate, test, and evaluate the group's ability to perform the operations and techniques utilized in combat operations. Not only did the ships operate as a group amongst themselves in a British capacity, but at times they would separate and join an American carrier group to demonstrate allied co-operation and interoperability. Further signalling close relations with her allies, the carrier and most of the strike group made an historic first visit to Canada, making Halifax, N.S., Queen Liz's first port of call after crossing the Atlantic. Not only did this visit demonstrate the Royal Navy's close relationship with the Commonwealth nation, but it also showed a high level of regard for one of Canada's oldest dockyards and a key Allied port during the Second World War. Today, Halifax is the home of Maritime Forces Atlantic (MARLANT), the eastern base of operations for the Royal Canadian Navy. Fleet commander for the Royal Navy, VAdm Jerry Kyd, who also was Queen Elizabeth's first captain, further emphasized the importance of this alliance. “We all recognize that the security of the world isn't getting any easier. This reinforces the needs for the fundamental alliances like NATO and bilaterals around the world, but acting in coalition. This ship embodies much of that; embarked today on board are many nationalities from across the Commonwealth, including Canadians. So, we're very proud that there's an alchemy that is coming together here in the British carrier program that is across the Commonwealth and it's fantastic. I think it reinforces these links that are so vital as we face down the challenges we will inevitably face in the coming decades.” British F-35Bs The other primary purpose of WESTLANT 2019, however, is the very first arrival and deployment of British F-35B aircraft. Until the first U.K. fighter landed on Oct. 13, Queen Liz had only fielded jet aircraft during her previous WESTLANT exercise in 2018, when American Marine Corps F-35B jets validated the developmental concepts of the ship through more than 500 successful takeoffs and landings. For this year's exercise, Queen Liz would be joined by jets from 617 Squadron “Dambusters” and 17 Test and Evaluation Squadron. Pilots from the newly stood up 207 Squadron have also embarked to further their training and operational preparations. For the United Kingdom, the ship heralds the return of fixed-wing aviation to the Royal Navy and the Fleet Air Arm. British F-35B aircraft have been undergoing testing along with pilot training in the United States, and just this year have begun moving pilot training to the U.K. To facilitate that program, 207 Squadron was reactivated at RAF Marham with jets previously used at Marine Corps Air Station Beaufort in the U.S. 207 Squadron is the third F-35 squadron for the country, alongside the fully operational 617 Squadron. Testing of the fighters continues in the United States with the 17th Test and Evaluation Squadron at Edwards Air Force Base in California. Carrier Air Group commander James Blackmore, who in 2009 flew the final flight of a Harrier from the last British carrier, the HMS Ark Royal, was enthusiastic about the upgrade. “The level of capability is decades on from where we were. What one aircraft can do now . . . you can deliver what would've taken four to eight aircraft in the past. Marrying that with the HMS Queen Elizabeth, a fifth-generation carrier designed purely for the F-35, you've got a marriage made in heaven.” Unlike other aircraft carriers of the world, Queen Liz is arriving on the scene as the first fifth-generation carrier, touting incredible autonomy and a light crew. Compared to her similar-sized American Nimitz and Ford class counterparts, which operate crews of around 4,000 strong, Queen Liz sails on a minimum crew of only 800, rising to around 1,400 with air wing and other specialty staff embarked. Various autonomous aspects of the ship include a fully automated weapons storage system very similar to those found in storage warehouses. Software controlled, robotic platforms and racks within the ship move bombs and ammunition from magazines to the flight deck and hangar bay with only the tap of a screen. The usage of the system is the first of its kind in a maritime application, and it greatly reduces the time and number of crew needed to safely transfer and arm aircraft. The ship herself, and her operations, are quite unique. Featuring minimal personnel on deck, flight operations take place utilizing a system of colour-coded uniforms and are controlled from the ship's second island. Unlike American carriers, Queen Liz features two islands as a redundancy. When in normal operation, the rear island controls flight operations while the other controls the ship itself. Radio communications are relayed between the deck personnel and the islands have large LED information boards showing what is occurring. These boards display information such as flight time, aircraft number, landing/launch site, and direction of flight. The ship, her crew, and her strike group are readying for their first operational deployment in 2021, which will see the full embarkation of a U.S. Marine Corps F-35B squadron, the very first allied deployment of its kind for either nation. This deployment will set sail for the Mediterranean Sea, the Persian Gulf, and ultimately end up in the Pacific before returning to the U.K. https://www.skiesmag.com/news/queen-liz-behind-the-scenes-on-britains-newest-aircraft-carrier

  • UK Declared F-35 Operational Despite Issues, Auditors Say

    UK Declared F-35 Operational Despite Issues, Auditors Say

    Tony Osborne The UK declared the F-35 operational even though the fleet was suffering from availability, infrastructure, logistics and security issues, auditors have revealed. The UK National Audit Office (NAO) found that the December 2018 initial operating capability (IOC) from land bases was granted with 67 exceptions, with almost one-third of those still yet to be resolved more than a year later. It is not clear on how many criteria IOC (Land) was judged. In its report studying how new capabilities are delivered into front-line operations, the NAO reported that in the run-up to the milestone there had been delays in the provision of synthetic training facilities. This impacted the availability of pilots and maintainers, while operational availability of the aircraft “hampered the ability to deliver training.” The report appears to confirm the reasons behind a 34-day flying break by the UK-based fleet in the late summer of 2018 reported by Aerospace DAILY. Plans to use simulators for training have been frustrated by “technical difficulties and delays in security vetting.” The NAO said the UK Ministry of Defense is able to use exemptions when bringing a new capability into service. Capabilities that do not meet specifications but are deemed good enough would be given an exemption. The NAO also says that IOC acceptance criteria for the F-35 was not finalized “until several years” after business case approval in the second half of 2017. Exemptions arose from “not being able to demonstrate deployability through a planned exercise,” because of aircraft availability, a reliance on contractors for mission support because of a lack of trained Royal Air Force personnel, and a lack of access to mission support training facilities in the U.S. Another challenge was an inability to program aircraft with UK mission data independently of the U.S. This has since been addressed with the opening of the Australian, Canadian and United Kingdom Reprogramming Laboratory (ACURL) at Eglin AFB, Florida, which was declared operational in February. The NAO notes that some 20 of the exemptions had still not been resolved as of last month. But the NAO says the Royal Air Force and Royal Navy have made progress in the areas of training personnel and logistics. The UK now has 15 F-35Bs based in the country flying with front-line unit 617 Sqdn. and with 207 Sqdn, a training unit. Since their arrival to the UK, the aircraft have been deployed to Cyprus and flown operational missions in the Middle East. They also recently took part in a Tier 1 Red Flag exercise with Five Eyes partners Australia and the U.S. A Lockheed Martin spokesman said that while it was for the customer to answer questions concerning IOC, “the F-35 program globally continues to mature, and Lockheed Martin has made significant steps in terms of reliability and aircraft availability, with the global fleet averaging greater than 65% mission-capable rates and operational units consistently performing near 75%.” Questions to the UK Ministry of Defense had not been answered at the time of publication. https://aviationweek.com/defense-space/budget-policy-operations/uk-declared-f-35-operational-despite-issues-auditors-say
