In my interviews with F-35 pilots, one word repeatedly came up: “survivability.” Surviving the Lockheed Martin F-35's primary mission—to penetrate sophisticated enemy air defenses and find and disable threats—requires what the fifth-generation jet offers: stealth and a stunning array of passive and active sensors bringing information to the pilot. The F-35 can see trouble coming—ahead, behind, or below the aircraft—far enough in advance to avoid a threat or kill it. Faced with multiple threats, the sensor suite recommends the order in which they should be dispatched.
U.S. forces first took these capabilities into combat last September, when Marine F-35Bs struck the Taliban in Afghanistan (five months after its combat debut with the Israeli air force). More than 360 of the multi-service aircraft—Air Force F-35As, Marine short-takeoff-and-vertical-landing Bs, and carrier-capable Cs—have been delivered to 16 U.S. airbases and to seven other countries. Reaching these milestones has not been easy. The program's difficulties and its cost—$406 billion for development and acquisition—have been widely reported. But now the F-35 is in the hands of the best judges of its performance, its pilots. I asked eight of them—test pilots who contributed to the jet's development as well as active-duty pilots—about their experiences. Here, in their own words, are their answers.

WEST LAFAYETTE, Indiana—The U.S. Defense Department says data from an upcoming four-year test campaign covering 40 flights and three basic vehicle concepts will lay the foundation for a comprehensive hypersonic weapon road map that should allay growing congressional concerns over potential overlaps in costly weapons development capability. To a quarter of the tests, representing as many as 10 flights, will be focused on air-breathing scramjet-powered vehicles, says Mike White, assistant director for hypersonics at the Office of the Under Secretary of Defense for Research and Engineering. Speaking to Aerospace DAILY on the sidelines of the inaugural National Defense Industrial Association (NDIA) hypersonics capability conference at Purdue University here, White says test results from both boosted glide vehicle flights and powered missiles will form the basis for the integrated development plan. The overarching road map also will include the integration of a counter hypersonic development strategy, the preliminary steps toward which have been proposed by both the recently formed Space Development Agency (SDA) and the Missile Defense Agency. The SDA is studying a space-based distributed satellite architecture, while the latter has proposed a Hypersonic and Ballistic Tracking and Surveillance System (HBTSS). “Offensive and defensive coordination is my job,” White says. The bulk of the prototype tests will be conducted using the common hypersonic glide body (C-HGB). Developed by Sandia National Laboratories, the bi-conic re-entry vehicle has been adopted as the basis for near-term boosted glide weapons by the U.S. Air Force, Army and Navy, with only minor differences in each version planned to reflect the varying operational characteristics of each role. The Army, which plans to ground launch the Long-Range Hypersonic Weapon (LRHW) from transporter erector vehicles, is meanwhile making the first moves toward industrializing production of what up to now has been small batch manufacturing runs of experimental vehicles. The service has issued a solicitation for transition of the design and production capability of the initial prototype LRHW C-HGB variant out of Sandia into industry. A contract award is expected to be issued this month. Other versions of the C-HGB are in development for the Navy's vertically launched Intermediate Range Conventional Strike Weapon (IR-CPS), and the Air Force's Hypersonic Conventional Strike Weapon (HCSW). Underwater launch tests of the IR-CPS, which follows the successful Flight Experiment-1 test in October 2017, from the Pacific Missile Range Facility in Kauai, Hawaii, are due to run through 2024. The Air Force is scheduled to complete critical design review of the HCSW in 2020 prior to launch tests from a B-52. At least five other flight-test campaigns make up the remainder of the hectic four-year plan, three of which will be focused on the DARPA-led Tactical Boost Glide (TBG) vehicle and two proposed follow-on air-launched rapid response weapon (ARRW) vehicles in competitive development by Lockheed Martin and Raytheon. The balance are two air breathing vehicles, also in development by Lockheed/Aerojet Rocketdyne and Raytheon/Northrop Grumman, which will be evaluated under the Air Force's Hypersonic Air-Breathing Weapon Concept (HAWC) program. Despite the ongoing efforts to refine the hypersonic road map, the proliferation of prototype vehicle programs continues to cause concern in Congress. Warning that not all programs will receive the funding requested in the fiscal 2020 budget, Peter Visclosky, chairman of the House Appropriations Subcommittee on Defense, says some reductions are planned. Commenting at the NDIA event, he says, “Justifications in the budget for this effort receive the same scrutiny as every other program in the department and unfortunately certain aspects of that 2020 budget request were lacking.” Without identifying particular initiatives, Visclosky adds, “There were cuts to those specific programs where the justifications did not lead to a review. Each of the services impacted have been made aware of the issues that the committee has raised and the need to better define the strategy for the investment in these systems.” Visclosky also cautions that hypersonics, which is provisionally funded with a budget of $2.3 billion for fiscal 2020 and $10.5 billion over the period to 2024, also faces broader threats at a time of increased spending on other high-profile defense programs. “I am concerned about affordability in the future because this is a competitive process,” he said. “We have a nuclear modernization process that is underway and there is going to be a bulge in the federal budget. There is a new submarine and there is going to be a bulge in the budget. It is the same for the new [B-21] bomber under development and, while the Army doesn't have that ‘one' new program, collectively for the modernization program there is going to be one. “We need to make sure there is a concerted effort for commonality and collaboration to a common technical standard and system architecture. I think this will drive better affordability into the sustainment of the system,” he adds. https://aviationweek.com/defense/integrated-hypersonic-plan-forms-amid-overlap-concerns

By: Joe Gould WASHINGTON ― The Pentagon is facing billions of dollars in pandemic-related claims, which may force it to dip into modernization and readiness accounts if Congress doesn't backfill the money, the department's top acquisitions official said Wednesday. Testifying at the House Armed Services Committee, Undersecretary of Defense for Acquisition and Sustainment Ellen Lord reaffirmed the Pentagon's commitment to request supplemental appropriations from Congress, beyond its fiscal 2021 budget of $740 billion. It's been seven weeks since Department of Defense officials first publicly disclosed a request was coming; that request is currently sitting with the White House Office of Management and Budget. The defense industry claims are expected to be covered by Section 3610 of the coronavirus relief package, among other provisions, Lord said. To give an idea of the scope, one of the major prime contractors told the DoD it and its suppliers could claim as much as $1 billion. Under Section 3610, the Pentagon and other agencies can reimburse suppliers for expenses to keep workers employed. Under other provisions, contractors can seek reimbursement for leave and DoD-directed purchases of personal protective equipment, cleaning, and costs associated with spacing out workers in factories. “The department does not have the funding to cover these costs,” Lord said, which she later said were “in the lower end” of “double-digit billions of dollars.” Lord affirmed the Defense Department would need Congress to pass supplemental appropriations beyond its fiscal 2021 budget during an exchange with HASC ranking member Mac Thornberry, R-Texas. “Otherwise these contractors are going to have to eat several billion dollars, which could well come at their employees' expense, which this was supposed to help to begin with,” Thornberry noted. “There's a choice there,” Lord said. “Whether we want to eat into readiness and modernization ― and slow down modernization or readiness on an ongoing basis ― or whether we want to remedy the situation in the next six months or so ... and continue to have the ready forces we need for our national security.” Though some House Democrats have expressed reservations about the size of the Pentagon's budget request, HASC Seapower and Projection Forces Subcommittee Chairman Joe Courtney, D-Conn., expressed support, saying: "The intent of Congress needs to be followed up on with an appropriation.” Courtney called on the DoD to provide Congress the data underlying its request, when the request actually arrives on Capitol Hill, saying it would foster conversation among lawmakers. The Pentagon has rough calculations, but contractors have not yet filed claims, Lord said, because Congress has not drafted an appropriations bill. She speculated the full extent of the issues will emerge over time. “I believe they are concerned that they'll get a one-time shot and want to make sure what the entire situation is,” she said. “We believe we understand the lower end of the number.” https://www.defensenews.com/congress/2020/06/10/defense-industrys-covid-costs-could-tank-dod-modernization-plans/
