  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

  Opinion: How New ‘Predators’ Are Reshaping Aerospace Landscape

  By Antoine Gelain Behind the big aerospace and defense (A&D) primes like Boeing and Airbus and the “Super Tier-1s” such as United Technologies (UTC) and GE, a very different type of company is shaping the global A&D industrial landscape in a way that may be even more impactful than high-profile UTC-Raytheon-type mergers. Companies such as Teledyne, TransDigm and Heico are the spearheads of a breed of A&D players dedicated to “components and subsystems,” with explicit and perfectly executed “horizontal” external growth strategies. Their track records are impressive: These three companies—with combined revenues of more than $10 billion—have collectively made close to 200 acquisitions and delivered more than 20% average annual growth rate in either profitability or share value over the last 20 years. Thanks to such returns and skyrocketing market valuations, they are able to outbid most other contenders when going after an acquisition target by leveraging the so-called “accretive effect.” This effect boosts the acquiring company's earnings per share, as long as the price paid for the target as a ratio of the enterprise value (EV) over its earnings before interest, taxes, depreciation and amortization (EBITDA) is lower than that of the acquiring firm. As it happens, the current EV/EBITDA ratio of the three above-mentioned companies stands at more than 18 (see graph). By comparison, most other A&D companies have an EV/EBITDA ratio in the 9-13 range. Such “buying power” is enhanced by operational synergies (for instance, in corporate overheads, sales and marketing), which immediately boost the profitability of the acquired company and can therefore be factored in the offer price. This gives them an additional edge against pure financial investors like private equity (PE) funds, which have historically been strong buyers of such component and subsystem businesses. Two recent deals in Europe (one still ongoing) illustrate this new balance of power. The first concerns Souriau-Sunbank, a $360 million-revenue specialist in interconnection technology for harsh environments. After being owned successively by two PE funds and bought by Esterline (now TransDigm) in 2011, it was again put up for sale last year. While expectations were that a PE fund would grab it, another industrial buyer, Eaton Corp., won the contest, paying the hefty price of $920 million (an EV/EBITDA multiple of 12). The second deal relates to a French company called Photonis, a world leader in night-vision technology for defense and space applications, for which Teledyne is apparently bidding—and offering a price 30% higher than the highest PE bid! These deals highlight the limits of the traditional private equity model (too short-term and too short-sighted) and why the “new predators”—all publicly listed companies—are in a much better position to continue to thrive. In fact, by combining “private equity-like growth in value with liquidity of a public market,” as TransDigm puts it, they are not only beating PE players at their own game, but they are also capturing a significant share of the A&D capital market by offering investors an attractive alternative to the traditional vertically integrated groups such as UTC, Thales or Safran. These groups are typically too busy focusing on large systems and equipment to realize that they would actually benefit from articulating a proper “component and subsystem” strategy. They would benefit not only because their portfolios are still full of such businesses, but also because their long-term competitiveness largely depends on their ability to nurture a strong network of strategic suppliers, in terms of both criticality for their own systems and national sovereignty. As it happens, Photonis seems to be such a strategic supplier, since the current French government just announced it would veto the Teledyne deal, hoping to give other French or European companies or investors time to make a competitive offer for the business. But because PE funds, at least in Europe, are somewhat faint-hearted when it comes to ambitious sector-specific “horizontal” portfolio strategies, and because Europe has no industrial player able to compete with the likes of Teledyne, the outcome of the process is still highly uncertain. In any case, Teledyne, Heico, Transdigm and similar companies are surreptitiously reshaping the A&D industrial landscape by buying technological nuggets and component businesses left and right, on both sides of the Atlantic. In the process, they are boosting their shareholders' returns and changing the balance of power with both traditional private equity investors and large vertically integrated A&D groups. As the saying goes: One man's meat is another man's poison. https://aviationweek.com/aerospace/manufacturing-supply-chain/opinion-how-new-predators-are-reshaping-aerospace-landscape
