  Carderock Uses High-Fidelity Signature Simulation to Train Surface Combat Systems

  By Benjamin McNight III, Naval Surface Warfare Center, Carderock Division Public Affairs WEST BETHESDA, Md. (NNS) -- In the world of simulations, getting a system to act as close to authentic as the real-world situations it represents is always the main goal. Naval Surface Warfare Center (NSWC), Carderock Division develops high-fidelity acoustic simulation and training systems, giving naval personnel the ability to practice combat scenarios virtually. The Combined Integrated Air and Missile Defense (IAMD) and Anti-Submarine Warfare (ASW) Trainer, better known as CIAT, made its official debut in December 2018 at Naval Base San Diego. In June, Naval Station Norfolk became the site for another CIAT installation. Motions to create this trainer began in 2014, according to Rich Loeffler, Carderock's senior scientific technical manager, director for signatures, tactical decision aids and training systems (Code 705). “CIAT is what we refer to as a Combat Systems Team Trainer,” Loeffler said. “Meaning that your goal is to bring in the whole portion of the crew that would be operating the combat system and train them in a shore site how they can best utilize the system when they are at sea.” Carderock shares CIAT responsibilities with NSWC Dahlgren Division. Dahlgren is responsible for the overall system integration and manages the IAMD aspect of the trainer, while Carderock leads the development of the acoustic and ASW capabilities. Carderock also has capabilities that contribute to the IAMD training. Using the periscope simulation that creates a real-time visual simulation of what one could see through the periscope of a submarine, Loeffler said they were able to utilize that technology for the surface ship trainer in the CIAT. “In this case, they have deck cameras if they want to be able to see when a missile launches from the forward or aft launchers. We basically provide the visuals for that,” he said. By modeling the threats and the ocean environment and then stimulating the actual tactical combat system software, the CIAT system is highly flexible in the ability to train real-world scenarios. With the many possibilities of training situations that can be created within the CIAT comes the need to use multiple sources of knowledge to create effective training situations that will benefit the fleet. “We'll work with people like the Office of Naval Intelligence to get threat intelligence data, we'll work with folks like the Naval Oceanographic Office to get the latest environmental models and databases, and then we'll work with the tactical programs themselves to get the tactical software,” Loeffler said. “Our role here at Carderock has been to leverage signature simulation capabilities we have developed over the years across submarine, surface and surveillance ASW trainers and provide the system design, development, integration and testing support to implement the CIAT requirement to support the fleet's training needs,” he said. Before the CIAT existed, the Surface ASW Synthetic Trainer (SAST) was developed by Carderock as an on-board embedded training system within the AN/SQQ-89 A(V)15 Sonar system. Loeffler said beginning in 2008, they went through a series of large analyses to compare and contrast what the simulation produced with what operators saw at sea. The data from that testing helped further develop the SAST and subsequently create the CIAT. Now, they are able to represent all components of the operations they run from the physics modeling perspective, such as what sounds are generated and how they propagate through the water, interactions with interfering objects and sea-state effects on these variables. “Since we're acoustically stimulating the actual tactical software of the sonar system, the users are operating the systems just as they would at sea,” he said. Loeffler believes that there is not anything off limits for what the CIAT can do, but adapting with new threats will require the right development within the trainer to represent the real-world situation. Although the system is relatively new, discussions on the next steps in the development of the trainer are already taking place with the help of Center for Surface Combat Systems (CSCS) defining and prioritizing fleet training requirements “CSCS is basically the primary stakeholder that owns the surface-ship training schoolhouses, and they've done their requirements review to see what additional capabilities they'd like to see in the next version of CIAT,” Loeffler said. “So, we're going through that process, assessing those requirements and looking for what would go into the next version to further improve training and also address training of the new combat system capabilities as they are being introduced into the fleet.” https://www.navy.mil/submit/display.asp?story_id=110471

  China to sanction Boeing, Lockheed and Raytheon over Taiwan arms sales

  Joe McDonald BEIJING — China's government said Monday it will impose sanctions on U.S. military contractors including Boeing's defense unit and Lockheed Martin for supplying weapons to rival Taiwan, stepping up a feud with Washington over security and Beijing's strategic ambitions. Raytheon Technologies Corp. and “relevant American individuals” associated with the sales also will be affected, said Foreign Affairs Ministry spokesman Zhao Lijian. He gave no details of what penalties might be imposed or when. The ruling Communist Party claims Taiwan, which split with the mainland in 1949 during a civil war, as part of its territory and has threatened to invade. Washington promised in the 1980s to reduce and eventually end weapons sales to Taiwan but insists its dispute with Beijing must be settled peacefully. “In order to safeguard national interests, China decided to impose sanctions on the American companies that were involved in arms sales to Taiwan,” Zhao said at a regular news briefing. Chinese-U.S. relations have plunged to their lowest level in decades amid disputes about security, technology, the coronavirus pandemic and human rights. Taiwan has long been an irritant in relations. Washington has no formal relations with the island's democratically elected government but is its main ally. U.S. law requires the government to ensure Taiwan can defend itself. Weapons sales to the island have increased in quantity and quality. Last week, Beijing demanded Washington cancel a planned sale of 135 precision land-attack missiles valued at more than $1 billion to improve its defenses. The sale “seriously undermined China's sovereignty and security interests,” Zhao said. China has stepped up military activity around Taiwan in an attempt to force concessions from the pro-independence administration of President Tsai Ing-wen. The Communist Party is using the mainland's growing economic weight to pressure other governments to cut diplomatic and unofficial ties with Taiwan. Beijing regularly pressures American companies, including Boeing, in an effort to influence U.S. policy. China is one of Boeing's biggest markets for commercial aircraft, which might make it vulnerable to a boycott, but Zhao mentioned only Boeing's military arm, Boeing Defense, not its civilian jetliner business. Lockheed Martin and Raytheon also supply radar and other technology for civilian aviation. The two governments have put sanctions on companies and individuals on both sides over complaints about human rights, computer hacking and other issues, though it is unclear whether they have any effect. Washington has imposed travel and financial bans on Chinese officials and companies it says are linked to abuses in the northwestern region of Xinjiang, where Muslim minorities have been detained in re-education camps, or Hong Kong after Beijing tried to tighten control by imposing a national security law. Beijing has retaliated by announcing sanctions against some U.S. legislators. Zhao called on Washington to “stop arms sales to Taiwan and stop any military interaction with Taiwan,” adding: “We will continue to take necessary measures to safeguard national sovereignty and security interests.” https://www.defensenews.com/global/asia-pacific/2020/10/26/china-to-sanction-boeing-lockheed-and-raytheon-over-taiwan-arms-sales/
