    In War, Chinese Shipyards Could Outpace US in Replacing Losses; Marine Commandant

    “Replacing ships lost in combat will be problematic," Marine Commandant Gen. David Berger writes in a forthcoming paper. "Our industrial base has shrunk while peer adversaries have expanded their shipbuilding capacity. In an extended conflict, the United States will be on the losing end of a production race.” By PAUL MCLEARYon June 17, 2020 at 4:44 PM WASHINGTON: The Commandant of the Marine Corps, Gen. David Berger, dismisses current Marine and Navy plans for amphibious ships as “obsolete,” and worries that in any conflict, China could replace damaged ships faster than the US in a draft operating concept obtained by Breaking Defense. The warnings are the latest in a campaign waged by the reform-minded Berger to overhaul how the Marine Corps trains and equips to meet the challenges of China and other advanced nations, while working more closely with the other armed services and allies around the globe. In the sharply-worded 22-page document, Berger rejects war plans anticipating a Cold War-style confrontation in which huge ships can creep close to shore free from the threat of precision-guided munitions being launched from batteries deep inland. He calls the current configuration of amphibious ships “the most obvious manifestation of this obsolete paradigm” in a draft document obtained by Breaking Defense. In an unsigned draft of the unreleased report, “Naval Campaigning: The 2020 Marine Corps Capstone Operating Concept,” Berger underlines the need for new thinking about how the Marine Corps and Navy will fight an advanced Chinese military that can control islands, coastlines, and vast swaths of the sea with aircraft carriers, a swelling blue ocean fleet and long-distance precision munitions. The old way of thinking “is also exemplified by our current amphibious warships and maritime prepositioning ships, which are large and built for deployment efficiency rather than warfighting effectiveness,” he writes. “These superb, multipurpose ships are extremely expensive—meaning we've never had the desired number.” Berger also raises significant concerns about the United States' ability to replace any combat losses, even in a short, sharp conflict. “Replacing ships lost in combat will be problematic, inasmuch as our industrial base has shrunk, while peer adversaries have expanded their shipbuilding capacity. In an extended conflict, the United States will be on the losing end of a production race—reversing the advantage we had in World War II when we last fought a peer competitor.” The stark admission comes as the Navy's shipyards struggle under the disruptions caused by COVID-19, leading the service to order an emergency call up over 1,600 Reservists to fill labor shortages to do repair work on aircraft carriers and submarines in a desperate effort to get them back out to sea as soon as possible. Berger takes care not to blame the Navy for building expensive, relatively slow amphibious ships to carry Marines across the globe. “These issues should not be construed as a criticism of our Navy partners who built the fleet—to include the types of amphibious warfare and maritime prepositioning ships the Marine Corps asked for—that was appropriate to the security era within the constraints of finite resources.” But that era is now over the Corps wants to build a more dynamic “inside force” of smaller ships that can operate within range of Chinese and Russian weapons and pack a potent offensive punch while offering more and smaller targets than the current amphibious fleet. But these small ships won't replace their bigger cousins — they'll come in addition to them, creating new issues for both Navy budgets and the limited number of shipbuilders who can produce hulls for the sea service. The ships will also need ports to call home. “One can think of basing forces and lots of smaller vessels in theater, but this raises the issue of where to put everything and doesn't seem to be a ready solution that replaces divestiture of large ships,” said Dakota Wood, senior research fellow for defense programs at The Heritage Foundation. In recent weeks, the Navy met with shipbuilders to talk about plans for a new class of logistics ship that can operate under fire and resupply Marines deep within the range of enemy precision weapons. The Next Generation Medium Logistics Ship would resupply both ships at sea, as well as small, ad hoc bases ashore. The ship fits within plans Berger has made to stand up several Marine Littoral Regiments designed to move fast and have their own integrated anti-air and possibly anti-ship weapons. The Corps and Navy are also looking to buy as many as 30 Light Amphibious Warships in coming years, which would be much smaller than the current amphibious ships. The draft document doesn't include any those specifics. But Berger has already done that work in previous statements and documents, where he outlined plans: to rethink the role that large amphibious ships play in future; divest of M1 Abrams tanks; cut artillery units; slash helicopter squadrons; and reassess the role F-35s might play in future operations. Berger has admitted he realizes he needs to undertake this transition within existing budgets, leading him to call for cutting tanks, helicopters, and even some end strength. But for the Navy, Wood said, “I think much of this will be added cost because it must maintain current capabilities (types of ships) while developing new capabilities. It does not have the luxury of getting rid of current before new replacements are ready.” A significant omission in all of these plans is the absence of a larger, coherent naval strategy. The 30-year shipbuilding plan, due to Congress in February, continues to be missing in action. A major Navy force structure review was rejected by Defense Secretary Mark Esper earlier this year. The force structure review, currently being taken apart by Deputy Defense Secretary David Norquist, is expected this fall. The Navy's plans are in such a fluid state that Vice Adm. Stuart Munsch, head of the service's Warfighting Development office, cited Chinese attention as a reason to decline to give a progress report in a call with reporters earlier this month. “I'm not going to divulge our intentions,” he said. “I'm very conscious that, if I say anything public, I'm an authoritative source and the Chinese will key on what I say, and likewise any kind of public-facing document that we put out as well.” Pressed to explain what the Navy's strategy for operating in a world with competing great powers looks like, Munsch said, “I'm not sure how you would see that keeping our intentions for warfighting classified is something you would want as an American citizen.” While Berger continues to push out papers and strategies for pushing the Marines into the future, the Navy, which will provide much of the lift he needs, is still at the drawing board. https://breakingdefense.com/2020/06/in-war-chinese-shipyards-can-outpace-us-in-replacing-losses

    Space Development Agency orders 8 satellites to track hypersonic weapons

    Nathan Strout WASHINGTON —SpaceX and and L3 Harris will contribute satellites to track hypersonic weapons to the Space Development Agency's planned mega-constellation, with the nascent agency announcing it had selected the two companies to build its first wide field of view satellites Oct. 5. Under the contracts, each company will design and develop four satellites equipped with wide field of view (WFOV) overhead persistent infrared (OPIR) sensors. Operating in low Earth orbit, the sensors will make up the inaugural tranche of the SDA's tracking layer—the Pentagon's new effort to track hypersonic weapons from space. “This SDA tracking layer is going to consist of a proliferated, heterogeneous constellation of WFOV space vehicles that provide persistent global coverage and custody capability. That's going to combine with activities in the Missile Defense Agency as they build toward their Hypersonic and Ballistic Tracking Space Sensor (HBTSS) medium field of view (MFOV) space vehicles,” Acting Deputy Undersecretary for Research and Engineering Mark Lewis told C4ISRNET. According to the announcement, SpaceX will receive $149 million while L3 Harris will receive $193 million. According to SDA Director Derek Tournear, the awards were the result of a full and open competition, with the selection based purely on technical merit. SpaceX has made waves with its Starlink constellation—a series of satellites built to provide commercial broadband from low Earth orbit—and the Department of Defense has tested using Starlink to connect various weapon systems. However, the company does not have a history building OPIR sensors. According to Tournear, the company will work with partners to develop the sensor, which it will then place on a bus it is providing. SpaceX already has a production line in place to build a bus based on its Starlink technologies, added Tournear. “SpaceX had a very credible story along that line—a very compelling proposal. It was outstanding,” he said. “They are one of the ones that have been at the forefront of this commercialization and commodification route.” L3 Harris will develop an OPIR solution based on decades of experience with small satellites, small telescopes and OPIR technologies. “They had an extremely capable solution. They have a lot of experience flying affordable, rapid, small satellite buses for the department,” noted Tournear. “They had the plant and the line in place in order to produce these to hit our schedule.” Tracking hypersonic weapons The contracts are the latest development as the SDA fleshes out its National Defense Space Architecture (NDSA), a new constellation to be comprised of hundreds of satellites primarily operating in low Earth orbit. These satellites are expected to make up tranche 0 of the SDA's tracking layer, which will provide global coverage for tracking hypersonic threats. The glue that holds the NDSA together will be the transport layer, a space-based mesh network made up of satellites connected by optical intersatellite links. Like most planned SDA satellites, WFOV satellites will plug directly into that network. “The idea is it connects to the National Defense Space Architecture—the NDSA transport layer—via optical intersatellite links,” said Lewis. “And that will enable low latency dissemination for missile warning indications. It will provide track directly to the joint war fighters.” SDA issued two contracts in August for its first 20 transport layer satellites. York Space Systems was awarded $94 million to build its 10 satellites, while Lockheed Martin was awarded $188 million. That transport layer capability is essential to the tracking layer's mission. Because they are so much closer to the Earth's surface than the U.S. Space Force's missile tracking satellites in geosynchronous orbit, the WFOV sensors will naturally have a much more limited field of vision. In order to track globe traversing hypersonic missiles, the WFOV satellites will have to work together. Once the first satellite picks up a threat, it will begin tracking it until it disappears over the horizon. During that time, it is expected to transmit its tracking data to other WFOV satellites over the transport layer. So as the first satellite loses sight of the threat over the horizon, the next WFOV is ready to pick it up, and so on and so forth. From there, the WFOV satellites will pass the tracking data — either directly or via the transport layer — on to the medium field of view satellites being developed by the Missile Defense Agency as their HBTSS. “SDA is developing the low cost proliferated WFOV space vehicles that provide the missile warning and the tracking information for national defense authorities, as well as tracking and cueing data for missile defense elements,” explained Lewis. “Meanwhile, the Missile Defense Agency is developing the high resolution HBTSS MFOV space vehicles — those can receive cues from other sources including the WFOV system—and they'll provide low latency fire control quality tracking data.” “The MFOV HBTSS satellites will then be able to hone in and actually be able to calculate the fire control solution for that missile, send those data to the transport satellites with a laser comms system ... and then the transport system will disseminate that to the weapons platform as well as back to [the continental United States, where MDA can broadcast that information],” added Tournear. MDA issued $20 million contracts to Northrop Grumman, Leidos, Harris Corporation and Raytheon to develop HBTSS prototypes in Oct. 2019. Tournear noted that proposals for HBTSS “are being written as we speak.” Together, HBTSS and the SDA's tracking layer are meant to provide the data needed to take out hypersonic threats—which Congress is increasingly concerned by. “It's part of an integrated DoD OPIR strategy. So the wide field of view sensors and the medium field of view sensors are really integral to this whole NDSA system and legacy strategic missile warning capability,” said Lewis, praising MDA and SDA for working together to build a heterogeneous solution. Spiral development Of course, this initial tranche won't provide global coverage up front. As part of its spiral development approach, SDA plans to continuously add satellites to its mega-constellation in two-year tranches, with each tranche including more advanced technology. The tracking layer is not expected to reach global coverage until 2026, said Tournear. But as the constellation is built out, the more limited initial capabilities will be used to help integrate the space-based assets with war fighters. “We call tranche 0 our war fighter immersion tranche,” said Tournear. “What that means is, its goal is to provide the data in a format that the war fighters are used to seeing on tactical timelines that they can be expected to see once we actually become operational. The whole purpose of tranche 0 is to allow the war fighters to start to train and develop tactics, techniques and procedures so that they can create operational plans for a battle where they would actually incorporate these data.” With tranche 1 in 2024, the tracking and transport layers will essentially reach initial operating capability, said Tournear. That will include persistent regional coverage. According to Tournear, the tranche 0 satellites are set to launch in September 2022. Tournear told C4ISRNET his agency is planning to issue a separate solicitation for launch services later this week. That solicitation will cover all of the tranche 0 satellites, including the 20 transport layer satellites the agency ordered in August, the eight WFOV satellites and the HBTSS satellites https://www.c4isrnet.com/battlefield-tech/space/2020/10/05/space-development-agency-orders-8-hypersonic-weapon-tracking-satellites/

    USAF Issues Contracts for Supersonic Air Force One

    by Chad Trautvetter - September 4, 2020, 12:56 PM Exosonic and Hermeus—relatively unknown developers of faster-than-the-speed-of-sound passenger aircraft—recently were awarded separate contracts by the U.S. Air Force's Presidential and Executive Airlift Directorate to develop executive transports that could be used as Air Force One. The former company is working on a 70-passenger supersonic airplane, while the latter is developing a 20-seat hypersonic airplane. The contract awarded to Exosonic, which was announced earlier this week, is for the company's low-boom, Mach 1.8 twinjet that would fly U.S. leaders up to 5,000-nm nonstop, allowing them to more quickly meet with world leaders or react to developing situations. Meanwhile, Hermeus's USAF award granted earlier this month for its Mach 5 airplane comes under an “other transaction for prototype agreement direct to Phase II contract” after the company successfully tested a hypersonic engine prototype in February. The company said it has taken an “off-the-shelf gas turbine engine and operated it at flight speed conditions faster than the famed SR-71.” Though performance and specification data for its Mach 5 jet are scant, it claimed the aircraft will be able to fly from New York to London in about 90 minutes. Neither company has yet provided development timelines for these airplanes. https://www.ainonline.com/aviation-news/business-aviation/2020-09-04/usaf-issues-contracts-supersonic-air-force-one
