  U.S. Security Requires Multiple Elements of Deterrence

  BY C. TODD LOPEZ In the context of U.S. defense policy, "deterrence" is typically understood to mean "nuclear." And America's nuclear triad — ground-based missiles, air-delivered bombs, and submarine-launched missiles — serves as America's biggest form of deterrence, which underwrites everything its men and women in uniform do. But according to Chief of Naval Operations Adm. John M. Richardson, nuclear weapons are just one of multiple elements of deterrence the U.S. must consider either for itself, or for being aware that other nations might be using them. During a July 2 breakfast presentation hosted by the Mitchell Institute for Aerospace Studies in Washington, Richardson laid out five such elements of deterrence already in use or that must be considered more deeply. Nuclear "It's an incredibly powerful military capability where potentially everybody gets destroyed," Richardson said. "We must maintain our ability to be competitive and relevant in this domain ... [and] strike back at anybody who can pose an existential nuclear threat to the homeland." The triad itself includes ground-based missiles — commonly referred to as intercontinental ballistic missiles; submarine-launched ballistic missiles; and air-launched cruise missiles dropped from bomber aircraft. In all three areas the U.S. is underway with modernization efforts. But the nuclear environment globally is changing, Richardson said. "More nations are seeking to join the club," he said. Some of those nations can bring high-tech weapons, while some are using low-tech, including dirty bombs and systems that can be manufactured with 3-D printers. Additionally, not all nuclear weapons are "strategic" in nature. Some are smaller "tactical" weapons. "The nuclear element of this mix remains very relevant, very active, and deserves a lot more attention in my mind," Richardson said. Cyber Richardson said when it comes to cyber as a deterrent, the U.S. can't maintain only defensive capabilities. "We have to have an ability for offensive cyber to truly achieve a sense of deterrence there," he said. Recent cyber provocations, he said, are "multidimensional in ways that may or may not have been expected." Included there, he said, are theft of intellectual property, invasion of privacy, invasion of identity, distortion of identity, "and most recently, perception management. This perception management idea ... might be kind of our new Sputnik moment." Space "The competition is absolutely heating up in space," Richardson said. "Of these elements that are going to constitute a tailored strategic deterrent approach, space has got to be one of those." Richard posited that in space, it might become apparent that, using directed energy weapons, it proves far easier to destroy something in space than it is to put something back up into space. "These things operate really fast ... and space goes away as an asset," he said. "You can see kind of a mutually assured destruction scenario in space pretty easily. Have we thought about that going forward?" Chemical, Biological Capabilities Increasingly, Richardson said, chemical and biological deterrence will come into the mix, especially as technologies such as CRISPR — a genome editing tool — allow for more tailored capabilities. "One of the self-deterrent aspects of chemical/biological is that it's very hard to control. It goes viral, if you will," he said. "But with these tailoring things, you can get a lot more specific. It becomes a lot more targetable. And so, it's something we have to mind." Conventional Weapons U.S. deterrence advantages in conventional weapons have relied, so far, on superior targeting ability, Richardson said. But that may become less important. "We have better sensors, better satellites, better ways to connect that data with our command and control systems, our targeting systems," he said. "We had an advantage in terms of precision." Now, he said, such sensors are ubiquitous, and commercial and military sensors are going up into space. There are cameras everywhere. "This idea of being able to locate things with precision is becoming more ubiquitous," he said. "It's less of an advantage. It's really the team that can manage that information better that's going to achieve the advantage." https://www.defense.gov/explore/story/Article/1896147/us-security-requires-multiple-elements-of-deterrence/

  Australia changes how it will buy drones for shipborne operations. How is industry reacting?

  By: Mike Yeo MELBOURNE, Australia — Australia's search for a new unmanned aircraft system to operate from its naval vessels has taken a new twist, as the service announced tweaks to its procurement program to streamline the process and put it in a position to take advantage of future technological advances. Speaking at a media event during an unmanned aircraft conference during the ongoing Avalon Airshow, officers from the Royal Australian Navy, or RAN, confirmed that it was rolling its two-stage procurement program into one. The program, Project Sea 129 Phase 5 Maritime Tactical Unmanned Aerial Systems, will look for a single prime contractor to offer a system to operate from all of the RAN's major fleet units, primarily its upcoming 12 offshore patrol vessels and nine future frigates. Sea 129 Phase 5 had previously been split into two stages, with the first seeking a system to operate from the OPVs and the second to equip the frigates. According to RAN Capt. Adrian Capner, Sea 129 Phase 5 will seek a platform systems integrator, or PSI, to be put in charge of the entire program, with the ability to meet capability requirements taking precedence over platform. “We will tell you what we want the system to do; you are going to come forward and show us how you expect to achieve that,” Capner told the audience. These requirements include being able to operate from the flight deck of a German-designed Lurssen OPV 80-class ships selected by Australia, which are the smallest ships slated to use the selected UAS. The aircraft must be able to perform surveillance and maritime domain awareness missions in Antarctic conditions, and participate in humanitarian assistance and disaster relief. Capner said the RAN is open to using multiple platforms to achieve the program's capability goals, adding that the PSI will also be responsible for constant upgrades to the UAS, as the service needs the system to stay relevant over the next few decades. The program is currently at the request for information stage, with Capner confirming that a request for tender is expected in the first half of 2020 and an initial operating capability planned for the mid-2020s. This change in procurement strategy appears to reduce the burden of risk on the RAN and lessen concerns about operating outdated technology by the time the platform enters service. Rather, these burdens shift to the winning PSI, who will be responsible to managing the program and adjusting for technological changes when the system is in service. The reaction to these changes from potential bidders has been mixed. James Lawless, business development manager at Saab Australia, called it an “intelligent way to approach [the program],” noting that it mirrors Saab's strategy in partnering with UMS Skeldar and Airflite to offer the UMS Skeldar V-200 UAV. Meanwhile, Melissa Pina of Northrop Grumman told Defense News that the company will continue looking for its offering based on the latest development. Northrop Grumman previously offered its MQ-8C Fire Scout drone for Sea 129 Phase 5 Stage 2 for the RAN's future frigates. The Fire Scout is slated to be the platform of choice to go onboard U.S. Navy ships, . The RAN is currently conducting trials on the use of UAS under a “navy minor project,” operating Schiebel's Camcopter S-100, the ScanEagle by Insitu (a subsidiary of Boeing), and other UAS from land bases and onboard its ships. https://www.defensenews.com/digital-show-dailies/avalon/2019/02/27/australia-changes-how-it-will-buy-drones-for-shipborne-operations-how-is-industry-reacting/
