    Major Submarine Contractor Drops Navy Missile Tube Biz

    The disclosure comes as the Pentagon has been looking for ways to backstop key parts of its industrial base as supply chains slowed due to the COVID epidemic. By PAUL MCLEARY WASHINGTON: One of the Navy's primary suppliers of missile tubes for its nuclear submarines is planning to walk away from the military business, a move that will drop the number of domestic companies capable of doing the work to two at a time when the service is in a scramble to ramp up its sub-building efforts. BWX Technologies President Rex Geveden says that the company is “not likely to pursue” any more Navy business and will repurpose a factory in Indiana that makes the components once the next set of deliveries of missile tubes wrap up in 2022. The Navy work “just doesn't have the margin profile that we want to see in the business,” Geveden said in a Tuesday investor call. BWX was slated to build the missile tubes for the new Columbia subs, but prime contractor Electric Boat says it has options to replace the company in coming years. The company “works with multiple suppliers to ensure we can meet the Navy's schedule requirements on these important programs,” a spokesperson emailed. “These are Babcock Marine, BAE Systems, Precision Custom Components and BWX Technologies. BWX Technologies will complete all currently contracted work for EB by 2022.” This comes as the Pentagon has been looking for ways to bolster key parts of its industrial base as communities shut down and workers are told not to report to work or take time off, due to the COVID epidemic. In a call with reporters late last month, Navy acquisition chief James Geurts acknowledged that the service is deeply worried that such closures and slowdowns could have wide-ranging impacts on shipbuilding. “I am absolutely interested in ensuring that we don't lose large chunks of the industrial base,” he said. “Restarting an industrial base that you lose is really hard, really painful, and takes a long time. We are absolutely focused on ensuring we do not lose an industrial base because we don't have the time or resources to re-generate it later when we need it.” The winnowing of such a key part of the industrial base will place more pressure on the handful of other companies who can do this sort of work, something to which Pentagon leadership is particularly sensitive. Overall, the Navy plans to buy 12 Columbia-class submarines between 2021 and 2035, with 10 of those coming 2026 and after. In the near-term, it plans two Virginia-class subs per year between 2021 and 2026, meaning shipyards will have to pump out two to four submarines a year in the mid-2020s. The new Columbia submarines will begin being delivered to the Navy in 2030, just in time to begin replacing the Cold War-era Ohio-class subs as the Navy's leg of the nation's nuclear triad. The subs will carry 70 percent of the nation's stockpile of warheads allowed by the New Start treaty with Russia. Falling in to replace the Ohio's on time would be a critical failure for the nation's nuclear triad, as the aging ships will have next to no life left in them by the end of the decade, and leaving the sea leg of the nuclear enterprise in some jeopardy. Babcock Marine is a UK-based company, but does work on some components that are used for both the Columbia program and the UK's Dreadnaught submarines, which shares similar missile tubes with the Columbia effort. In 2018, Virginia-based BWX was forced to pay $27 million to fix welding problems on the Columbia tubes, after issues were found on a total of 44 tubes. So far, 21 of those have been fixed and 11 delivered to the Navy. Navy officials have closely tied the modernizing of the current Virginia-class subs with the building of new Columbia's, warning that since they share a base of companies who can make precision parts for nuclear-powered submarines. So any problem with one program will have knock-on effects to the other. Geurts and others have said the Navy would prioritize the health of the Columbia effort over Virginia if they had to. If the House of Representatives gets its way, however, billions more will flow into the Virginia program than the White House has called for. Last week, the House voted to fund the construction of a second Virginia-class submarine in the 2021 budget request, after the White House dropped the planned buy to one submarine in its submission. The push was led by Rep. Joe Courtney, chairman of the Seapower Subcommittee who represents the Connecticut district that's home to Electric Boat. The bill now includes $6.8 billion to produce two Virginia-class attack submarines, approximately $2.5 billion more than the White House's own request, and $2.2 billion more than the Senate's. “The budget request we received from the White House flew in the face of testimony that we've heard from Navy leaders, experts, and combatant commanders,” Courtney said in a statement. “It requested the fewest ships in over a decade, and it eliminated construction of the second Virginia-class submarine in 2021—a vessel that the Navy quickly listed as its most important unfunded priority in 2021.” https://breakingdefense.com/2020/08/major-submarine-contractor-drops-navy-missile-tube-biz

  • KC-46 Progress Revives Next-Generation Tanker Talks

    KC-46 Progress Revives Next-Generation Tanker Talks

    Steve Trimble Proposals for a next-generation tanker that would come after the last Boeing KC-46 delivery in fiscal 2029 have popped up every few years since 2006, only to get sidetracked by yet another acquisition process misstep or technical problem afflicting the program's frustrating development phase. As a fresh sense of optimism gathers among senior U.S. Air Force leaders about the direction of the KC-46 program, a new discussion has started between Defense Department officials and the Air Mobility Command (AMC) about the future of the air-refueling mission. Some proposals in the discussions include revived versions of various older concepts for weaponized larger tankers and smaller stealth tankers. But this time, discussions involve taking a wider view of the overall need to defend and deliver fuel to aircraft in combat, with implications for base defenses, the size and range of future fighters and next-generation tanker designs. A perceived turnaround in the fortunes of the KC-46 program allows the Air Force to reopen the next-generation discussion. Since at least 2016, a heated dispute over Boeing's original design—and, later, proposed fixes—for the KC-46's remote vision system (RVS) sidetracked planning for a next-generation tanker. Air Force officials complained that Boeing's original RVS design fell short of operator requirements, especially when the receiver aircraft was backlit by the Sun. In addition, the canted layout of the belly-mounted, panoramic cameras created subtle distortions in the displayed video that proved bothersome to some RVS operators, Air Force officials say. The Air Force and Boeing finally agreed to a redesign plan in January 2019. The Air Force is finalizing a test report on an enhanced RVS, which was formerly known as RVS 1.5. AMC officials have committed to review the test data but offered no promises on whether they would approve the enhanced RVS to be installed in the KC-46. The installation would require parking a fleet of more than 36 delivered KC-46s to complete the retrofit, and the AMC remains unsure whether the improvement is worth the delay. The enhanced RVS offers only software updates to the current system, but the AMC clearly wants more. Boeing has committed to a more dramatic upgrade called RVS 2.0. Including hardware and software changes, this Boeing-funded, second-generation RVS system is expected to meet the image-resolution standards demanded by the Air Force and create a path to inserting the software algorithms necessary to give the KC-46 an optional autonomous-refueling mode. Boeing is scheduled to deliver the first 12 RVS 2.0 shipsets by the end of 2023 and begin the retrofit process on delivered KC-46s, says Gen. Jacqueline Van Ovost, the AMC commander. The AMC expects a production cutin for RVS 2.0 starting in 2024, although Boeing's KC-46 global sales and marketing director, Mike Hafer, says the first RVS 2.0-equipped aircraft could start rolling off the assembly line in late 2023. Will Roper, the Air Force's assistant secretary for acquisition, technology and logistics, says the progress toward fielding the RVS 2.0 makes him feel “excited” about the KC-46 program. “I think we've turned a new page,” he says. In mid-September, Roper and Van Ovost met to discuss what will follow the KC-46. The next-generation tanker discussion comes after a series of dramatic acquisition decisions surrounding Air Force aircraft. Most visibly, Roper led a push in 2018 to cancel the Joint Stars recapitalization program, which was replaced with the Advanced Battle Management System (ABMS). More quietly, Roper also drove the Air Force to rethink the acquisition strategy for the Next-Generation Air Dominance (NGAD) program. The ABMS and NGAD are now characterized by an architecture of multiple systems, with no single-aircraft silver bullet solution. Roper acknowledges that the nature of tanker operations does not immediately lend itself to a distributed multiplatform solution. “We can break up a J-Stars [replacement into multiple systems],” Roper says. “We may be able to break up an [E-3 Airborne Warning and Control System] in the future, but we can't break up fuel easily.” Still, Roper prefers to address the future air-refueling problem in an era of great power competition with a similar architectural approach as ABMS and NGAD. “When there's a solvable problem and you need to turn multiple knobs, the Pentagon likes to turn one and only one,” Roper says. “And [aerial refueling] sounds like a really good architectural question that you'd want to have an architected solution for—[rather than] design a one-solution candidate in the form of a platform.” Roper's turnable knobs for a future air-refueling system cover a wide range of options, including two with only indirect impacts on a tanker aircraft design. To Roper, the problem of air refueling includes defending the bases closest to an adversary where aircraft can be refueled on the ground. Likewise, another part of the solution is to move away from relatively small fighter aircraft that lack sufficient range for a Pacific theater scenario. “Maybe having small, currently sized fighters is not the way to go in the future,” Roper says. “Thinking about bigger fighters is a natural question to lay alongside the question, ‘How does your future tanker force look?'” Air-refueling capacity also is partly a function of the vulnerability of the tanker aircraft. Fewer and perhaps smaller tankers may be possible if existing tanker aircraft could operate closer to the battlefield. The Air Force now uses fighters on combat air patrols to defend high-value assets, such as tankers, surveillance and command-and-control aircraft. Those fighters conducting the patrols also add to the refueling burden. A possible solution is to weaponize tankers such as the KC-46 and KC-135. The Air Force is developing podded defensive lasers and miniature self-defense munitions. “We don't put weapons and sensors on tankers to shoot down aircraft, but the current KC-46 is a big airplane with the ability to mount sensors and weapons on the wings,” Roper says. “We're going to look at all those [options].” The Air Force also believes a new tanker aircraft is necessary. As far back as 2002, research began on stealthy mobility aircraft under the Air Force Research Laboratory's Speed Agile program. As the KC-X acquisition program kicked off, the Air Force released a tanker road map in 2006 that called for launching a KC-Y acquisition program in 2022 and a KC-Z program by 2035. By 2016, AMC leaders openly discussed proposals for leapfrogging the KC-Y requirement, which sought to buy a larger version of a commercial derivative. Instead, AMC officials began investigating concepts for an autonomous stealthy aircraft. By 2018, Lockheed Martin's Skunk Works had defined a concept for such an aircraft, which featured an undisclosed refueling technology that could dock with a receiver aircraft without compromising radar stealth. As discussions have reopened in September, the Air Force is again considering the acquisition of a mix of larger and smaller aircraft to fulfill the demand for in-flight refueling in the 2030s and 2040s. “One trade we can do is having bigger tankers that stand off a lot farther,” Roper says, “[and] having smaller, microtankers that do that last mile, the dangerous mile—and we expect to lose some of them.” The Air Force's budget justification documents suggest research on a next-generation tanker will continue at a low level: Nearly $8 million was requested in fiscal 2021 to “assess promising configurations in high- and low-speed wind tunnels.” The Air Force also is designing a small, pod-mounted tactical air-refueling boom, according to budget documents. The latter suggests that one option for increasing refueling capacity for aircraft equipped with boom receivers is to integrate a podded fuel-delivery system on tactical aircraft, such as a Lockheed Martin C-130. “I expect that as we really look at airpower in the truly contested environment, we'll be looking at fuel very strategically,” Roper says. “We may have a different solution for outside [a threat area] versus inside. And I think we will value, increasingly, aircraft that have range for the last mile.” https://aviationweek.com/defense-space/aircraft-propulsion/kc-46-progress-revives-next-generation-tanker-talks

    Navy C-40 Fleet Deliveries Complete

    Adds Two Airplanes, One Squadron The Navy's C-40 fleet has undergone some major changes in the last few months - adding two airplanes, one squadron and completing its current planned aircraft procurements. The Tactical Airlift Program Office (PMA-207) took delivery of the Navy's 16th aircraft in June and 17th aircraft on September 26. The Navy's latest C-40A aircraft will be assigned to U.S. Naval Reserve Fleet Logistics Support Squadron (VR) 57. These last two deliveries have allowed the C-40 fleet to realign and expand its horizons. "The C-40 plays an important role in the Navy Unique Fleet Essential Airlift (NUFEA) fleet," said CAPT Steve Nassau, PMA-207 Program Manager. “These extremely flexible logistics support aircraft are an integral part of every type of maritime mission, from humanitarian assistance to long-range, high priority deliveries.” The sixth Navy C-40 squadron was established last month. VR-51, nicknamed the Windjammers, deploying from Kaneohe Bay, Hawaii, received two C-40 aircraft from the fleet. The squadron will be fully operational in October, following receipt of its “Safe for Flight” certification. “The Safe for Flight certification is an entire program overview in which the government ensures that all contractor, air crew, and government operating procedures are in place and functioning correctly,” said Darwin Lazo, PMA-207 Medium Lift DAPML. “It is the final certification for a new squadron.” VR-51 will soon begin entering the VR deployment rotation. “There is always a C-40 deployed to US Central Command (CENTCOM), US European Command (EUCOM) and US Pacific Command (PACOM) to meet mission requirements,” said Donna Elliott, PMA-207 Medium Lift IPTL. Over the past year, the C-40 fleet logged 24,374 hours of flight time, completed 1,555 missions, transported 95,746 passengers and 20,012,934 tons of cargo. In doing so, the aircraft has maintained a 90% readiness rating and has played a vital role in providing military transport not available with contract or commercial carriers. The C-40, a commercial derivative of the Boeing 737-700C, is the mainstay of the Navy's medium lift capability. http://www.aero-news.net/index.cfm?do=main.textpost&id=b3d6746e-726d-4821-85ff-9b750f723f13
