  China’s latest class of warship makes its public debut

  By: Mike Yeo MELBOURNE, Australia – the first of a new class of guided missile destroyer from China made an appearance at a naval review to mark the 70th Anniversary of the country's navy. The Type 055 destroyer, named the Nanchang, was among several ships of the People's Liberation Army Navy or PLAN that took part in the naval review held off the northern Chinese city of Qingdao with Chinese President Xi Jinping in attendance. China's first aircraft carrier Liaoning, a refurbished Soviet-era ship, was also in attendance along with 18 warships from 13 other nations including Australia, India and Japan. The United States declined an invitation to send its ships to the naval review, and France was disinvited after its frigate Vendémiaire sailed through the Taiwan Straits prior to the event, Reuters reported. The Nanchang was launched at Shanghai's Jiangnan Changxin shipyard in June 2017. The Type 055, which is classed as a cruiser by the Pentagon, measures almost 590 feet and displaces 10,000 tons according to specifications released by China — although some naval analysts believe that figure is an underestimation. Each ship is also equipped with a total of 112 vertical launch cells that are capable of launching either surface-to-air or anti-ship missiles, and fitted with a modern sensor suite that includes phased array radars. Speaking at a regular press briefing conducted by China's Ministry National Defense on Thursday, Senior Col. Ren Guoqiang confirmed that the Nanchang is on the verge of completing sea trials and will be officially handed over to the PLAN later this year. In addition to the Nanchang, recent open-source satellite and aerial imagery show that seven other Type 055s are in various states of construction and fitting out at the two major Chinese naval shipyards in Shanghai and Dalian. The latter is also where China's first domestically-built carrier, which is based closely on the Liaoning, is currently being completed. Further underscoring the astonishing pace of China's ongoing naval buildup, the photos also show five other smaller Type 052D destroyers undergoing construction at Dalian with six more being built at Shanghai. The latter shipyard has four more destroyers of an unknown sub-type being put together, along with what are reportedly the modules for China's third and largest aircraft carrier. https://www.defensenews.com/global/asia-pacific/2019/04/26/chinas-latest-class-of-warship-makes-its-public-debut/

  Here’s who will build the US Army’s new missile defense radar

  By: Jen Judson WASHINGTON — Incumbent Raytheon will build the U.S. Army's new missile defense radar to replace the Patriot air and missile defense system's current radar as part of the service's future Integrated Air and Missile Defense System. The company has taken its years of experience refining gallium nitride, or GaN, technology at its Massachusetts-based foundry to help design a new radar system that will provide the Army 360-degree threat detection capability in a configuration that includes one large array in the front and two smaller arrays in the back. The contract is worth roughly $384 million to deliver six production-representative units of the Lower Tier Air and Missile Defense Sensor, or LTAMDS. “Our clean-sheet approach to LTAMDS reinforces Raytheon's position as the world's premier air and missile defense radar capability provider,” Ralph Acaba, president of Raytheon Integrated Defense Systems, said in a statement. The service earlier this year held a “sense-off” at White Sands Missile Range, New Mexico, between three working radars from Raytheon, a Lockheed Martin and Elta Systems team,and Northrop Grumman. The service analyzed the results and was in contract negotiations with the winner as the Association of the U.S. Army's annual conference, which kicked off Oct. 14. Brig. Gen. Brian Gibson, who is in charge of the service's air and missile defense modernization effort, told Defense News in an interview ahead of the show that negotiations were ongoing and that the award would happen soon. Without public knowledge of the win, Raytheon brought its offering for the LTAMDS competition to the show and passed out red lanyards advertising LTAMDS that said: “No time for a blind spot,” referring to the 360-degree coverage capability. Replacing the Patriot radar has been a long time coming. The radar was first fielded in the 1980s, and the Army previously attempted to replace the system with Lockheed Martin's Medium Extended Air Defense System through an international co-development effort with Germany and Italy. But that program was canceled in the U.S. after closing out a proof-of-concept phase roughly six years ago. Since then, the Army studied and debated how to replace the Patriot radar, while Raytheon continued to upgrade its radar to keep pace with current threats. The service has acknowledged there will come a point where radar upgrades will be unable to keep up with future threats. Taking years to decide, the service moved forward on a competition to replace the radar in 2017 and chose four companies to come up with design concepts for the capability — Raytheon, Lockheed Martin, Northrop Grumman and Technovative Applications. Toward the end of 2018, Raytheon and Lockheed were chosen to continue technology development under that program. But then the Army redirected its plans into a sense-off competition last fall. Raytheon is expected to build six prototypes by the end of fiscal 2022. The radar that Raytheon specifically designed for the Army uses next-generation GaN and is 7 feet longer but 11 inches more narrow than the current radar unit. But it no longer requires outrigger stabilizing legs. Rather, the system is held stable by jacks underneath, which means it takes up less space on the sides, according to Bob Kelley, Raytheon's director of domestic integrated air and missile defense programs for business development and strategy. The radar meets all of the Army's mobility and transport requirements, Kelley said, including fitting in a C-17 aircraft. The smaller arrays are about 50 percent of the size of the legacy Patriot system's array, but are twice as capable due to the advancements with GaN technology, he added. Though the Army backed off its 360-degree detection capability requirement for the competition, Raytheon has been steadfast about keeping that capability in its offering. In addition to being able to constantly cover 360 degrees, the radar can see farther than the currently fielded Patriot radar. That radar is unable to fully support the maximum kinematic range of the Patriot Advanced Capability-3 Missile Segment Enhancement that it fires. The Army claims that its effort to tie the Terminal High Altitude Area Defense System with Patriot would help the MSE missile reach its full potential. The LTAMDS will be able to fully support current missile systems including PAC-3 MSE range capability and future missiles ranges, Kelley said. https://www.defensenews.com/breaking-news/2019/10/17/heres-who-will-build-the-armys-new-missile-defense-radar
