  Raytheon plows ahead to build US Army’s future radar

  By: Jen Judson WASHINGTON — The first antenna array for the U.S. Army's Lower Tier Air and Missile Defense Sensor passed through initial testing at Raytheon's Massachusetts-based facility, and it will embark on future testing at an outdoor range in the short term, a company official told Defense News. The antenna array went into an indoor, climate-controlled test range, and its performance was evaluated against simulated targets, Bob Kelley, Raytheon's director of domestic integrated air and missile defense programs for business development and strategy, said during a March 16 interview. The technology “came out fantastic on the other side,” he added. Now the array will be mounted on a precision-machined enclosure for integration, Kelley said, and then it will head to a range for testing with real-world targets such as air traffic coming in and out of Boston's Logan International Airport. Raytheon is plowing ahead with an aggressive schedule to deliver the first LTAMDS radar to the Army next year. So far it's on track and on schedule. The company finished building the first radar antenna array in less than 120 days after being selected for the job, following a competition to replace the service's Patriot air and missile defense system sensor. The radar will become a part of the service's future Integrated Air and Missile Defense System that will replace the entire Patriot system. Raytheon also manufactures the Patriot. Raytheon has taken its years of experience refining gallium nitride 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 LTAMDS. The Army is working to rapidly deliver initial capability under an urgent materiel release. The service in 2019 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. https://www.defensenews.com/smr/army-modernization/2020/03/17/raytheon-plows-ahead-to-build-us-armys-future-radar/

  Navy Mulling How to Make Surface Fleet Flexible, Lethal

  By: Otto Kreisher WASHINGTON, D.C. — A panel of senior Navy civilian officials said the planning efforts for the future combat fleet was focused on making the fleet more flexible, interoperable and lethal. There also is an emphasis on open architecture to make it easier, quicker and cheaper to upgrade combat systems, they said. Those priorities would reduce the cost of sustaining the fleet going forward, the officials said at the American Society of Naval Engineers' annual Technology, Systems & Ship symposium on June 19. Michael Stewart, deputy director for integrated warfare systems, said his job was to look at the available capabilities across all the different surface platforms to make the fleet more capable and lethal. He also would ensure that all requirements going forward were clearly tied to the National Defense Strategy, since “we can't afford to fund everything.” John Hootman, the deputy director for surface warfare, said he was looking at the architecture for the future surface combatants in the 2030-2040 timeframe, when the Ticonderoga-class cruisers and some of the early Arleigh Burke destroyers would be retiring. But, he said, “we can't know what we'll need until we know how we'll fight.” In response to a question, Hootman praised the creation of the Surface Development Squadron, which will help in that effort to determine how the future fleet would fight. Hootman also emphasized the need to look at capabilities across the fleet, not at specific platforms, to promote commonality across the fleet, including a common combat system that could equip the whole range of surface combatants and even the amphibious ships. But that focus on common systems also could apply to the hull, mechanical and electrical elements of future ships. “The push for commonality is key.” Another official extended that quest to communications systems, arguing that every different circuit in the fleet reduces capacity, flexibility and the ability to integrate operations in the strike group. Steven Dries, filling in for Rear Adm. Steven Pardoe, director of integrated warfare, noted that the capabilities that ships would need in the future will change, which makes it all the more important to field systems that can be modernized with software changes, rather than having to tear out hardware. Hootman stressed the same thing as a way to more efficiently modernize ships and gain commonality. He also cited the savings in training sailors to operate and maintain systems that are common across platforms. https://news.usni.org/2019/06/19/navy-mulling-how-to-make-surface-fleet-flexible-lethal
