The Navy needs to overhaul several dry docks at its four public shipyards so they can accommodate new attack submarines and aircraft carriers -- but the first attempt to build a new dry dock in Maine is already facing cost-overruns and schedule delays.

Nathan Strout The American unit of Astroscale Holdings is entering the satellite life-extension market with the purchase of an Israeli company that specializes in developing on-orbit servicing solutions. Astroscale U.S. has acquired Effective Space Solutions, which develops life-extension solutions for satellites in geostationary orbit, or GEO. In addition to adding ESS' intellectual property to its portfolio, Astroscale is hiring all of the company's staff to form Astroscale Israel Ltd., which will remain in that country and serve as Astroscale's research and development group for geostationary satellite life-extension services. Astroscale, a global company based in Japan, is best known for its efforts to remove space debris from orbit. The company expects to demonstrate its end-of-life service later this year, which will see an Astroscale space vehicle capture debris and de-orbit it. But with this purchase the company is scaling up its understanding of — and ambitions for — on-orbit servicing. “Really, we've started thinking about the debris remediation part of the market as a subset of on-orbit services. It's one thing you can do once you have a satellite up there that can rendezvous and dock with other satellites,” said Ron Lopez, president and managing director of Astroscale U.S. “We're bringing all of those resources to bear to move into the GEO life-extension business, to complement what we're doing in [low Earth orbit] LEO on the debris and the situational space awareness side.” Astroscale claims that with its debris removal efforts in LEO and its new GEO life-extension effort, the company is now the only business solely dedicated to on-orbit servicing across all orbital regimes. Eventually, Astroscale could add satellite refueling, repair, upgrading, towing, salvage, situational space awareness and on-orbit manufacturing to its future portfolio for logistics services. But for now, the company is focused on providing life-extension services — supplanting the exhausted fuel reserves of a client satellite with the propulsion provided by an attached space vehicle. ESS' Space Drone platform will be used as the base for Astroscale's first life-extension vehicle. Lopez couldn't give a timeline for when the first life-extension mission would begin, stating that the timeline would be driven by customer demand. He added that he is in talks with potential customers. Astroscale will face some stiff competition as it enters the still nascent satellite-servicing market. SpaceLogistics, a Northrop Grumman subsidiary, successfully docked its own space vehicle with a commercial GEO satellite in February, marking the beginning of the first-ever commercial satellite life-extension mission. SpaceLogistics has also made important inroads with the Department of Defense. The company is working with the DoD to study the feasibility of providing life-extension services to four military satellites. And shortly after the firm's successful docking with a commercial satellite in February, the company announced it will partner with the Defense Advanced Research Projects Agency to field a pair of government-built robotic arms for on-orbit repairs. Astroscale also sees the DoD as an important customer for any GEO servicing efforts. “U.S. strategy right now is very heavily focused on space, specifically on building resiliency and achieving greater operational flexibility, which this kind of capability will allow U.S. government customers to do,” Lopez said. The company does not have any DoD contracts to date, but Lopez said it's in communication with key U.S. government stakeholders and has presented its solution to DoD representatives. Lopez also sees strong commercial interest in on-orbit servicing, which underpins the company's business plan and would allow the government to leverage commercial prices. Ultimately, Lopez believes Astroscale is well-positioned to compete. “Even though we're small, we're nimble and we have a real, meaningful global footprint,” he said. https://www.c4isrnet.com/battlefield-tech/space/2020/06/03/astroscale-leaps-into-the-satellite-servicing-fray

By Anthony Capaccio The U.S. Navy accepted delivery this year from Textron Inc. of the first two in a new generation of hovercraft for the Marines despite “extensive propeller blade cracking” that will require a redesign, according to service officials and documents. The previously undisclosed problem was discovered during mid-2019 tests of the $5.7 billion program to build new air-cushion hovercraft to move Marines from ship to shore. Even with the cracks unresolved, the Navy awarded Textron a $386 million contract for 15 more hovercraft that Congress had approved for fiscal years 2017-2020. But ordering those vessels was held up pending resolution of other technical problems, including issues with the main gearbox, drive-train integration and lubrication system, navigation electronics and bearings. The first two deliveries, in February and August, were each three years late. Hovercraft “have always been important for supporting the Marine Corps' ability to land forces ashore, and in coming years they are to form part of the toolkit for implementing the Corps' new wartime island-hopping strategy for countering Chinese military forces in the Western Pacific,” Ronald O'Rourke, an analyst with the Congressional Research Service, said. Taking delivery of the first two hovercraft allowed the Navy to begin initial operator training and “to move into the post-delivery test and trials period as we identify long-term” solutions for vessels in production, Navy spokeswoman Colleen O'Rourke said in an email. She described the flaws as “micro-cracks” in the composite structure of the blades that don't pose a safety hazard or “an immediate impediment” to operations. “The program is the first major naval acquisition program in more than 15 years to be designed ‘in-house' by the Navy rather than by private industry,” according to a Navy fact sheet. Reinforced Blades O'Rourke said the Navy, Providence, Rhode Island-based Textron and subcontractor Dowty Propellers, a division of General Electric Co., conducted a study “to understand the underlying cause and mechanisms to improve propeller blade performance.” That led to a near-term plan to provide “reinforced blade sets that will deliver later this year” while production and post-delivery testing continue and “blade redesign efforts are underway,” she said. She added that the eventual solution for the 73 hovercraft, known as Ship to Shore Connectors, “is not anticipated to result in any significant program cost increases.” Scott Donnelly, Textron's chief executive officer, told analysts Thursday on an earnings call that the program is “steadily improving” and “we're starting to feel good about that.” He said the contractor has “started to get more craft deliveries, the production lines are starting to run better, we're starting to get supply parts coming in at the right time” so “that's a program that obviously is going to start to be a contributor to the profit in the rest of the businesses.” Textron rose 6.6% to $34.21 at 10:24 a.m, the most since July 30, after third-quarter earnings per share from continuing operations beat the average analyst estimate. Currently, 12 additional hovercraft are under construction in Slidell, Louisiana. The vessels will replace the aging Landing Craft Air Cushion vehicle that became operational in 1986. The Ship-to-Shore Connector is a “franchise program” for Textron's Marine & Land Systems division, “which could more than double in revenue over the coming years as production accelerates,” Bloomberg Intelligence analyst Douglas Rothacker said in an email. Textron reports third-quarter earnings Thursday. Procurement funding is projected to soar from $20 million the Navy requested for this fiscal year to almost $380 million by 2025, according to program documents. The Navy's fiscal 2021 Selected Acquisition Report, obtained by Bloomberg News, said initial “Builders Trial” testing in mid-2019 uncovered “technical concerns with the propeller blades.” This resulted in a decision to divide the subsequent formal acceptance test into two events -- “unloaded” and “loaded,” which simulated carrying a 74-ton M1 tank. “After the loaded builders test, craft inspection revealed extensive propeller blade cracking,” it said. “To avoid additional blade loss,” the first vessel's acceptance tests “were conducted unloaded.” https://www.bloomberg.com/news/articles/2020-10-29/marines-combat-hovercraft-from-textron-have-cracked-propellers
