    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

  • Could a commercial drone replace the MQ-9 Reaper? The Air Force is considering it.

    Could a commercial drone replace the MQ-9 Reaper? The Air Force is considering it.

    By: Valerie Insinna WASHINGTON — The Air Force is looking for a replacement to the stalwart MQ-9 Reaper and intends to explore options ranging from commercial drones built by emerging tech firms to high-end unmanned aircraft, the service's top acquisition official said Tuesday. Will Roper, the Air Force's assistant secretary for acquisition, technology and logistics, said the service is working on a study that will inform the fiscal 2022 budget and lay out a path for replacing the MQ-9 Reaper made by General Atomics. "The Reaper has been a great platform for us. Four million flight hours, just undeniable overmatch in a low-end uncontested fight, and it is certainly saving lives,” Roper told lawmakers at a House Armed Services Committee hearing. “But as we look to the high end fight, we just can't take them into the battlefield. They are easily shot down.” The MQ-9 Reaper and its precursor, the MQ-1 Predator, have been the Air Force's workhorse drones in the Middle East over the past two decades, providing both real-time video surveillance and the ability to strike targets. But looking forward, the Reaper is ill-suited to a war with Russia and China while at the same time seen by the Air Force as requiring too much money and manpower to sustain for continued operations in low-threat environments. There likely won't be a single, one-size fits all solution for replacing the MQ-9, Roper said. The Air Force may need drones that “are more high-end, military-unique” systems, and “they'll likely be expensive,” he acknowledged. There may also be room for unmanned attritable aircraft, which are reusable but are cheap enough that they can be shot down in battle without incurring massive financial losses. For lower-end missions, the Air Force sees promise in the emerging unmanned systems market, where new entrants have begun creating long-loiter drones for applications in agriculture, communications and the oil and gas sector. “A lot of companies are targeting that market, not thinking about defense because we've been buying Reapers forever,” Roper said, who added that by buying from promising commercial drone makers, Air Force may be able to influence those companies to keep their supply chains out of China and to incorporate military-specific features — potentially even weapons. “I think if we do the program right on the commercial side, we might be able to bring a new entrant into defense without making them a defense prime,” he said, adding that funding from the Air Force could help a commercial company move from making prototypes to building up a stable production line that could further be grown to manufacture drones on a more massive scale. “Working with the Defense Department, you don't need the kind of production capacity that the globe does. So, we're a pretty good first stop,” he said. However, the Air Force may face an uphill battle in getting Congress to support a plan to replace the Reaper. The service in its FY21 budget request has asked for 24 more MQ-9s before ending the programs of record — a move that would curtail the program from 363 to 337 Reapers. The early shutdown of the line would have major financial implications for General Atomics, said Chris Pehrson, the company's vice president of strategic development, in a February interview with Air Force Magazine. “We're actually going out about 22 months ahead of delivery and procuring the long-lead item parts, ... whether it's [satellite communication] equipment or engines ... to negotiate the best prices and get the best deals for the government,” Pehrson said. “Having the rug pulled out from under your feet at the last minute kind of disrupts all your supply chain investments that you're making.” Top generals in the Middle East and Africa have also raised concerns about the demands for intelligence, surveillance and reconnaissance and privately helped stave off retirements of the MQ-9 by the Air Force in FY21. In its unfunded wish list, U.S. Central Command included additional contractor-flown MQ-9 hours as its number one priority, at a cost of $238 million. https://www.defensenews.com/air/2020/03/12/could-a-commercial-drone-replace-the-mq-9-reaper-the-air-force-is-considering-it
