Aircraft makers sweeten their offers in high-stakes Swiss warplane race
By: Sebastian Sprenger and Valerie Insinna
COLOGNE, Germany, and WASHINGTON — Four aircraft makers have submitted final offers for Switzerland's $6.5 billion aircraft program, with Airbus and Lockheed Martin touting different approaches to assembling their planes locally.
Nov. 18 was the deadline for the quartet of hopeful vendors, which also includes Boeing and Dassault, to deliver their vision — and price — for one of the largest procurement programs in Europe.
Switzerland is looking for somewhere between 36 and 40 new aircraft to police the country's airspace. The degree of local industry participation is shaping up to be a major factor for the famously independence-minded Swiss.
Airbus got an assist from four Eurofighter operators — Germany, Spain, Italy and the U.K. — who sent their ambassadors in Switzerland to a Nov. 19 news conference to talk up the prospect of a grander industrial and political partnership that would follow a Eurofighter pick.
The Swiss are expected to make a decision in early summer 2021, following a referendum vote this September that narrowly greenlighted the budget.
The Airbus offer includes final assembly of all aircraft by way of a partner company in Switzerland, the details of which the company plans to announce in December.
Michael Flügger, Germany's ambassador in Switzerland, touted the possibility of Eurofighter-based airspace-patrol cooperation along the Italy-Switzerland-Germany axis. In addition, he said, Switzerland joining the airplane's user club would mean the country can “export” training flight noise to remote areas in the other partner countries.
Franz Posch, who heads the Airbus campaign in Switzerland, told reporters that the company's plan to locally assemble all 40 of the notional aircraft would “more than fulfill” the offset requirements established by the Swiss government.
Lockheed Martin, with its F-35, also has high hopes for the Swiss competition, hoping to broaden the plane's user base in Europe. The company's offer includes a basic program of 36 jets, with options for an additional four aircraft, Mike Kelley, who leads the company's F-35 efforts in Switzerland, said during a Nov. 19 roundtable with reporters.
While Switzerland would be able to purchase parts through the spares pool shared by all F-35 operators, the offer also contains a six-month deployed spares package — a separate pot of parts that would be managed by the Swiss government, which was necessary to meet Swiss autonomy requirements.
To meet requirements for industrial participation, Switzerland would have the opportunity to domestically produce about 400 canopies and transparencies for F-35 aircraft, and Lockheed would establish a European hub for the maintenance, repair and overhaul of F 35 canopies and transparencies in Switzerland. In addition, the country would take on certain F-35 engine and airframe sustainment projects focused on maintaining the Swiss Air Force's operational autonomy, Kelley said.
Lockheed also plans to partner with Swiss industry to create a cyber center of excellence, which would prototype a unique data network for Switzerland and build a test bed that would allow Swiss companies to test cyber capabilities in a secure environment.
On top of those efforts, Lockheed is offering one last industrial participation opportunity to Switzerland. For an additional cost, Switzerland will be able to conduct the final assembly of four F-35 aircraft at existing RUAG facilities in Emmen, allowing the Swiss technicians that currently work on the country's aging Hornet fleet to build a deeper knowledge of the aircraft's design.
That option would add a “significant cost” to the total program, Kelley said, but could allow for overall savings throughout the life cycle of the program.
Boeing, meanwhile, has positioned its offer of an F-18 Super Hornet fleet as a logical extension of Switzerland's existing F-18 infrastructure. “As an F/A-18 operator, Switzerland will have the option to reuse up to 60 percent of existing physical and intellectual infrastructure, making the transition to a Super Hornet easier and more cost effective over the life of the aircraft,” the company said in a statement.
The aircraft offer, the statement added, would “easily fit” within Switzerland's current F-18 operating budget.
The reference to cost comes after Swiss officials stressed that the fighter portion of the Air 2030 air defense modernization program includes a cost ceiling of 6 billion Swiss francs (U.S. $6.6 billion), with with an eye on potential price reductions along the way.
“Currently, Boeing is working with more than 100 current and new partners across Switzerland to identify the right opportunities for its New Fighter Aircraft industry plan,” the company said.
France's Dassault, with its offer of the Rafale, is the only vendor keeping its cards close to its chest. Citing a commitment to confidentiality, a spokeswoman told Defense News the company had no plans to characterize its offer nor the “nature of the relationship” between the Swiss and French governments to that end.

Secret Bomber Programs Set For Possible Rollouts In 2021
Steve Trimble December 09, 2020 Strategic bombers are enjoying a stealthy renaissance against a backdrop of renewed competition among “great power” states: namely, the U.S., China and Russia. For more than a decade, all three countries have labored to push a new generation of stealth bombers into service under programs cloaked in secrecy, while at the same time expanding the capacity and quality of an aging bomber fleet. The first fruits of the new stealth-bomber generation may become visibly tangible to the public in 2021. Although the U.S. Air Force has backed off from a schedule revealed in July 2018 to fly the Northrop Grumman B-21 Raider for the first time on Dec. 4, 2021, the first aircraft still may emerge from Building 401 on Site 4 at Plant 42 in Palmdale, California, during the next 12 months. The Air Force's new schedule calls for first flight of the B-21 in 2022. Given the traditional 6-9-month period of outdoor ground testing in advance of any first flight by a new aircraft, the updated schedule still implies a strong chance of a factory rollout during the second half of 2021. Less is known of the construction status of China's first stealthy, flying-wing bomber, probably named the H-20. Since 2018, the U.S. Defense Department has estimated in annual reports to Congress that the H-20 is likely to be a stealthy, subsonic bomber resembling the Northrop B-2 or X-47B, with a range of at least 4,590 nm (8,500 km) and payload capacity of conventional and nuclear munitions totaling at least 10 metric tons. In 2019, the department added that the H-20 could “debut” during the 2020s. If the Pentagon's range estimate for the H-20 is accurate, it falls well short of the U.S. West Coast but encompasses most of the northern Pacific Ocean, including Alaska and Hawaii. A rollout and first flight remain possible in 2021. A corporate video by the Aviation Industry Corp. of China, the H-20's corporate developer, released at the end of 2019 teased that the H-20's unveiling would come “shortly.” In Russia, the Prospective Aviation Complex for Long-Range Aviation (PAK DA) bomber likely transitioned into the production phase during 2020. Satellite photos in early spring revealed a large new factory being erected inside Tupolev's industrial complex in Kazan. By May, major structural assemblies for the first test aircraft had entered construction, according to a report by TASS. The same report, citing two anonymous sources inside Russia's defense industry, put the schedule for completing final assembly in 2021. All three programs represent the first new bomber designs initiated since the Cold War. Service-entry schedules for the three have not been announced but will be coming around 30 years after Northrop's first-generation stealth bomber—the flying-wing, four-engine B-2A—became operational in 1997. The impact on the defense industry could be profound as production ramps up over the next decade. For the B-21, low-rate initial production should begin in 2022, Northrop CEO Kathy Warden says. That timetable suggests production-aircraft deliveries beginning two years later. Due to the secretive nature of the program managed by the Air Force's Rapid Capabilities Office, precise B-21 production unit costs are unknown. At the time of contract award in October 2015, the Air Force estimated the average B-21 unit cost over a production run of 80-100 aircraft would be about $550 million in 2012 dollars. Adjusting for inflation, the average cost has increased to about $632 million. With Pentagon officials expecting budgets to remain flat or decline over the next several years, one of the Air Force's biggest challenges will be finding ways to reduce costs in other programs to accommodate the B-21 as production ramps up. With the ability to fly in proximity and even within defended airspace, a stealth bomber offers an ideal combination of survivability, range and weapons capacity. The aircraft's stealthiness adds substantially to the production cost, but the trade-off is an aircraft that can carry less expensive, short-range weapons such as glide bombs. None of the great powers, however, is willing to part completely with an existing bomber fleet, despite aircraft designs that date back to the late 1940s. Leveraging heavy investments in new propulsion, sensors and weapons, the U.S., China and Russia will breathe new life into their aging Cold War-era platforms. By June 2021, the U.S. Air Force expects to award a contract for delivery of 608 new jet engines for 76 Boeing B-52s, replacing a fleet of 60-year-old, 17,000-lb.-thrust Pratt & Whitney TF-33-P-3 turbofans. GE Aviation's Passport and CF34, Pratt's PW800 and Rolls-Royce's BR.725-based F130 are the Air Force's options, with each representing a multi-generational leap in fuel efficiency and reliability. The Air Force also will demonstrate that Cold War bombers can perform a new role in the 2020s. A pylon modification will allow the B-52 to carry up to 22,000 lb. on each external hard point, enabling the aircraft to carry three Lockheed Martin AGM-183A Air-Launched Rapid Response Weapons on either wing. Boeing upgraded both conventional rotary launchers inside the weapons bays to carry up to eight cruise missiles each. If a new generation of scramjet-powered hypersonic cruise missiles now in development matches the size and weight of the AGM-86s now carried by the rotary launchers, each B-52 would be able to carry 22 long-range hypersonic missiles. A similar transformation will be demonstrated by the B-1B. In mid November, Air Force Global Strike Command showed a B-1B could accommodate a subsonic Lockheed AGM-158 Joint Air-to-Surface Standoff Missile (Jassm) on an external pylon. By extension, each of the B-1B's six external pylons could be adapted to carry hypersonic missiles such as the AGM-183s. Another eight hypersonic cruise missiles could be fired from the conventional rotary launcher inside the B-1B's weapons bays. Draft appropriations bills for fiscal 2021 in Congress include the Air Force's request to retire 17 B-1s and funnel the operating-cost savings to modernize what would be the remaining 45 aircraft in the fleet. The bomber renaissance also is seeing transformation of the Cold War-era fleets of the Chinese and Russian air forces. In mid-November, the People's Liberation Army Navy for the first time deployed the Xian H-6J to Yongxing Island, also known as Woody Island, in the South China Sea. While still unmistakably a descendant of the first Tupolev Tu-16 Badger delivered to China in 1958, the H-6J remains a potent weapon system against the U.S. Navy's Pacific Fleet, especially while armed with YJ-12 anti-ship missiles. Likewise, the People's Liberation Army Air Force revealed the H-6N in October 2019, showing China's first nuclear-capable bomber with the ability to be refueled in flight. Government-owned magazine Modern Ships published photos a month later of the H-6N carrying an air-launched ballistic missile in a recessed cavity carved into the fuselage. The weapon could be a medium-range, anti-ship DF-21. More recently, photos appeared of the H-6N carrying a different air-launched missile with a payload bearing a profile similar to the DF-17 hypersonic glide vehicle. Russia's bomber fleet modernization also extends beyond development of the PAK DA. Over the past year, the first versions of Tu-160 and Tu-95 bombers fitted with new engines have entered flight testing. Meanwhile, a second Tu-22M3M prototype entered flight testing in 2020, joining the first prototype that entered testing in December 2018 with new engines, avionics and missiles, including supersonic air-launched Kh-32s. https://aviationweek.com/aerospace-defense-2021/defense-space/secret-bomber-programs-set-possible-rollouts-2021

COVID-19 Forces USN To Expedite USAF Workshare Agreement
Lee Hudson The U.S. Navy has expedited its component workshare agreement with an Air Force aviation depot because of coronavirus-related workforce shortages. Fleet Readiness Center East (FRCE) located in North Carolina was initially scheduled to begin working on a Boeing F-18 cabin safety valve later this year while the Oklahoma City Air Logistics Complex's test chamber was closed for scheduled maintenance. But the time line was accelerated when Tinker AFB in Oklahoma had a significant number of workers unavailable due to COVID-19 risk mitigation efforts. The cabin safety valve is an integral part of the aircraft's environmental control system, Mary Linton, an aerospace engineer on the Gas Turbine Compressor-Pneumatics Fleet Support Team at FRCE, said in an April 27 statement. The valve is a component on both legacy F/A-18 Hornets and newer Super Hornets that acts as a backup to maintain cabin pressure above 23,000 ft. The part also serves as a supplement to the cabin air pressure regulator when the aircraft is in a rapid dive. “The original intent of bringing this workload to FRCE was to support Tinker Air Force Base through a major support equipment rework effort,” Linton said. “All of the great effort that went into establishing this capability proved even more critical to maintaining the readiness of the F-18 fleet as we navigate through the COVID-19 crisis.” The FRCE team was prepared to begin repairing, checking and testing the cabin safety valves in May, beginning with 20 per month before getting to a monthly rate of 40 by July, said John Miller, a planner and estimator with the Maintenance, Repair and Overhaul Logistics department at FRCE. To date, FRCE has completed 18 of the 40 units inducted so far, with plans to funnel 10 more into the pipeline. Once those first units are completed, the team must wait for additional valves to maintain the workflow. “The availability of components is still in flux due to COVID-19 and other factors, but the transition should move smoothly,” Miller said. https://aviationweek.com/defense-space/budget-policy-operations/covid-19-forces-usn-expedite-usaf-workshare-agreement
