  US Navy eyes new launchers on destroyers for hypersonic weapons

  By: David B. Larter WASHINGTON — With bigger, faster missiles in development and bound for the fleet, the U.S. Navy's engineers are considering installing upgraded launchers on the stalwart Arleigh Burke-class destroyers. The head of Naval Sea Systems Command, Vice Adm. Thomas Moore, told an audience at a conference of naval engineers that the Arleigh Burkes — due to their vertical launch system and Aegis missile capabilities — were easier to keep relevant than other destroyers such as the Adams and Spruance classes. Still, with the service attempting to keep the ships longer, new launchers may be in order to pace the threat from Russia and China, which have been developing their own hypersonic weapons. “Vertical launch system has been a real game changer for us. We can shoot any number of things out of those launchers,” Moore said. “We'll probably change those out and upgrade them for prompt strike weapons down the road.” Putting hypersonic weapons on surface ships would greatly increase the effectiveness of their strike capabilities. The current main strike weapon, the Tomahawk Land Attack Missile, is a subsonic missile that is vulnerable to evermore advanced Russian and Chinese air defenses. Prompt strike, which refers to a Pentagon-wide effort to field hypersonic weapons to quickly strike anywhere in the world, are most likely coming first to submarines, said Thomas Callender, a retired submarine officer and analyst with the Heritage Foundation. Because subs are stealthy and can sneak in close to land undetected more easily than a surface ship, they make the most sense. “They're looking at putting hypersonics on submarines first because where you can get access,” Callender said. “You can potentially then put them on surface ships as an added capability for them, but the submarines would be the priority for access and the ranges you can achieve.” The Navy is designing a new large surface combatant to replace the cruisers and ultimately the destroyers with larger missiles in mind. As a result, the ship may be fairly large, former Surface Warfare Director Rear Adm. Ron Boxall told Defense News last year. The benefit of larger vertical launch cells is that you can pack more missiles into each cell, if you are not using the cell for the larger hypersonic missiles, Boxall said. “We are going to need, we expect, space for longer-range missiles,” he said. They are going to be bigger. So the idea that you could make a bigger cell, even if you don't use it for one big missile, you could use it for multiple missiles — quad-pack, eight-pack, whatever.” The missiles that would go into a larger launcher are still very much under development. The Navy is teamed with the Army to develop a booster for a hypersonic missile, and the Army is leading a team with the Navy and Air Force to internally build a common glide body that is producible on a larger scale. Radar upgrades Naval Sea Systems Command is also examining installation of a scaled-down version of the air and missile defense radar AN/SPY-6, under development for the Flight III DDG. The scope of that project, however, remains to be determined. “We are looking at a scaled-back version of the air and missile defense radar to back-fit the Flight Is and Flight IIs, similar to how we are looking for a version of the [Enterprise Air Search Radar] developed for [the Ford-class aircraft carriers] to back-fit on some of the old Nimitz class,” Moore said. “I'm not sure how many ships it is going to go on, we're still doing the design work. It's a fairly significant change to the structure of the ship, AMDR versus Spy.” The purpose of the upgrade would be used to track the faster, more dynamic missiles under development by Russia and China. The array is a smaller version of the SPY-6 intended for the Flight III DDG, the first of which is now under construction at Huntington Ingalls Industries. The SPY-6 destined for DDG-125 will have 37 radar modular assemblies, or RMA, which are 2-foot-by-2-foot-by-2-foot boxes that use gallium nitride technology to direct radar energy on air targets. The Flight IIA version will have 24 RMAs in the array. A version of the radar planned for the FFG(X) future frigate is a nine-RMA configuration. The Navy wants to upgrade all of its DDGs to Aegis Baseline 9 or higher with a ballistic missile defense capability and extend the service lives to 45 years as part of an effort to grow the fleet. But the Navy is going to try to get 50 years out of its Flight IIA ships. The IIAs make up the bulk of the DDG fleet, with 46 total planned for the service — DDG-79 through DDG-124. DDG-127 will also be a Flight IIA. That upgraded SPY-6 will be far easier to maintain than the current SPY-1D. Raytheon claims the radar can be maintained by simply removing an RMA and switching it out with a new one, with the rest of the work performed offsite. https://www.defensenews.com/naval/2019/06/30/navy-eyes-new-launchers-on-stalwart-destroyers-for-putting-hypersonics-afloat/

  Duckworth: Army's New Helicopters Should Not Be Designed for Anyone Else

  By Matthew Cox WEST PALM BEACH, Florida -- Sen. Tammy Duckworth, a former U.S. Army helicopter pilot, said recently that the Marine Corps, Navy and Air Force would have to wait their turn if they want their own version of the Army's futuristic helicopters being developed under the Future Vertical Lift (FVL) effort. The Illinois Democrat and member of the Senate Armed Services Committee recently attended a high-profile flight demonstration of Sikorsky-Boeing's new SB-1 Defiant helicopter that was designed with the goal of replacing the UH-60 Black Hawk. The Army awarded a team from Sikorsky, part of Lockheed Martin Corp., and Boeing Co. a 2014 contract to build Defiant as part of the Joint Multi Role Technology Demonstrator (JMRT-D) program. A Textron Inc.-Bell team also received a contract under the effort and built the V-280 Valor, a tiltrotor-design helicopter that completed its first test flight in December 2017. Both the Valor and the Defiant prototypes are promising designs, Army officials maintain, that are capable of flying at speeds of more than 200 knots and will result in a replacement for the venerable Black Hawk as the service's new Future Long Range Assault Aircraft (FLRAA). Duckworth, a former Army National Guard officer who lost both legs after enemy forces shot down the Black Hawk she was flying over Iraq in 2004, said she intends to keep the FVL program from morphing into an unwieldy, joint effort. That's a pitfall that has thrust many joint-service programs into program delays and cost-overruns because of overly broad requirements. "This is an Army aircraft; we need to keep an Army mission," Duckworth told reporters at the Feb. 20 flight demo. "If the other services want to fall in behind it and develop something afterward and tweak it for what they need, that is fine, but we cannot build a Frankenaircraft ... that's going to meet the Marines' needs and the Navy's need and the Air Force's needs. "We need to not let the requirements start to meander and creep around because otherwise we will never get to where we need to and get these things fielded as quickly as possible," she added. In the past, the Pentagon has often tried to develop multiple versions of a major combat system, such as the new F-35 Joint Strike Fighter, which has been designed to satisfy the requirements of the Navy, Marine Corps and Air Force. The acquisition program for the advanced, stealth fighter began in the mid-1990s and still suffers from testing setbacks that have delayed a full-rate production decision. That Army-Marine Corps Joint Light Tactical Vehicle (JLTV) program, however, is considered a successful acquisition effort that began in 2006 after Humvees in Iraq could not withstand the destruction force of enemy homemade bombs attacks. JLTV took almost a decade to become a reality but, in August 2015, Oshkosh Corp. was selected over Lockheed Martin Corp. and AM General LLC to build the vehicle for the Army and Marine Corps. Meanwhile, for the second year in a row, the Army has reduced the number of JLTVs it will buy in fiscal 2021 to free up money to fund future modernization. FVL is one of the Army's top modernization priorities under a new strategy the service launched in 2017, with the goal of replacing most of its major combat platforms beginning in 2028. Leaders stood up Army Future Command, an organization designed to help the service's acquisition and requirements machines work more closely together in an effort to streamline what has traditionally been a slow-moving process to develop and field combat system. So far, the strategy appears to be working, since the FLRAA and the Future Attack Reconnaissance Aircraft (FARA) efforts are ahead of schedule, Duckworth said. Army officials are scheduled to down-select to two vendors to build final prototypes of the FARA next month. The service is also scheduled to begin a competitive demonstration and risk reduction phase for FLRAA, which is expected to last until 2022, the year the service plans to down-select to one vendor to build the Black Hawk replacement. "This is rare for defense procurement to actually be ahead of timeline instead of pushing everything to the right," Duckworth said. "I am very pleased with how well the Army is handling this development." The senator stressed, however, that she intends to continue strict oversight of the FVL to ensure it doesn't result in a waste of taxpayer dollars. "We can't be spending upward of $60 million per airframe," Duckworth said. "If we do that, then we can't field the number of airframes that we need to be out there in the force." Army Secretary Ryan McCarthy, who also attended the flight demo, stressed that the service's leadership is committed to making necessary cuts to outdated programs to free up money for FVL and other modernization efforts. "We don't have a choice. We are running out of letters to upgrade the existing platforms -- they are 40-year-old systems; the technology will not endure," he said. -- Matthew Cox can be reached at matthew.cox@military.com. https://www.military.com/daily-news/2020/02/25/duckworth-armys-new-helicopters-should-not-be-designed-anyone-else.html

  Airports to go on counter-attack with 'killer' devices and bazookas

  The Telegraph, Charles Hymas All Britain airports are increasing or reviewing their defences because of fears of copycat attacks ... following the chaos at Gatwick that ruined the travel plans of 140,000 people Britain's major airports are to step up security with military-grade detection systems that would help them counter Gatwick-style drone incidents by launching their own “killer drones” or shooting them down with firearms. The move emerged as Sajid Javid, the Home Secretary, Chris Grayling, the Transport Secretary, and Gavin Williamson, the Defence Secretary, prepared to meet today (Monday) to review progress on the police investigation and measures to protect the public from future attacks. All airports in Britain are increasing or reviewing their defences because of fears of copycat attacks, according to Whitehall sources, following the chaos at Gatwick that ruined the travel plans of 140,000 people. Gatwick is expected to be the first to operate detection technology designed to be as sophisticated as that being used by the crack RAF and Army signals teams deployed to the airport last week. It allows personnel to detect, track and photograph drones at a distance of more than 1km and up to 5km. Whitehall sources said options for countering the threat included airports deploying their own drones, firing bazookas with projectiles that trapped them in nets, or deploying police with shotguns to shoot them down. The military team was due to remain at Gatwick until the airport's own defence system was operational, possibly for the two weeks over Christmas. Stewart Wingate, the chief executive of Gatwick, said: “We are equipping ourselves with capabilities to detect and defeat drones.” A Whitehall source said: “The first thing is to detect when a drone is coming in and having enough distance in which to do that. Second is being able to track the signal.” The Metis Skyperion technology, thought to be used by the military, deploys cameras, laser rangefinders, radar and radio frequency scanners to pinpoint the drone. To install a similar system at a major airport could cost up to pounds 5m, according to one expert. To track the drone to its operator would require additional sensors that even the military has not deployed at Gatwick. Finding the culprit becomes easier if they remain in sight of their device. Gatwick declined to reveal the measures it was considering to “defeat” or “disrupt” any further attacks. Police at Heathrow are testing a SkyWall 100 bazooka, a shoulder-launched weapon that fires a projectile containing a net. “Some of the airports are putting up enhanced firearms capabilities, most are doing increased police patrols inside and outside,” said a Whitehall source. “Airports are also assessing and monitoring potential launch sites.” Legislation will be rushed through in the new year to enable electronic jamming by airports, bigger drone exclusion zones and new police powers. https://nationalpost.com/news/world/airports-to-go-on-counter-attack-with-killer-devices-and-bazookas
