The U.S. Navy Is Developing Mothership Drones for Coastal Defense
By Patrick Tucker,
The service is looking to accelerate the way it buys, builds and drills drones and robotic ships.
The U.S. Navy and researchers from Florida Atlantic University are developing robotic boats that can launch aerial and sub drones to protect U.S. coastal waters.
“Our focus will be on developing a multi-vehicle system that can safely and reliably navigate coastal waters with a high level of autonomy while performing assigned tasks,” Manhar Dhanak, director of SeaTech, the Institute for Ocean and Systems Engineering in FAU's Department of Ocean and Mechanical Engineering, said in a press release.
The AU researchers will develop new software tools for better sensing and collision avoidance as well as to allow the ship “to serve as a docking station” and power sub and air drones that latch onto it, according to a statement from the University. One aspect of the effort, developing software to help the surface vessel obtain a clear picture not just of obstacles to avoid but also friendly and hostile elements in the area, to help it better plan routes and paths for different missions.
It's an example of the types of prototypes that will become more common, according to a Navy roadmap for the development and acquisition of autonomous systems. This Strategic Roadmap for Unmanned Systems, which began circulating around the Pentagon last year, has not yet been released. But a predecisional copy obtained by Defense One shows that the Navy is pushing to develop and buy its drones faster, integrate them more aggressively in exercises and other activity, and work more closely with universities and other non-traditional research partners particularly in the design of new prototypes.
The Navy's research into unmanned weapons goes back to World War I research into flying munitions and torpedos. The term “drone” was coined in the 1930s by Cmdr. Delmar Fahrney, who was in charge of Navy research into radio-controlled aircraft.
More recently, the Navy has sought to incorporate ever-higher levels of autonomy into drills and activity. In 2014, the service ran a dramatic experiment that showed that a swarm of 13 autonomous roboticized boats might help defend a warship.
The Navy has also developed (and plans to soon deploy) the Sea Hunter, an unmanned ship that can guide itself on the open water while obeying international maritime laws. Former Defense Undersecretary Bob Work speculated that the Sea Hunter could be armed with ballistic missiles. “We might be able to put a six-pack or a four-pack of missiles on them. Now, imagine 50 of these distributed and operating together under the hands of a flotilla commander,” Work said at an event sponsored by CNAS. “This is going to be a Navy unlike any navy in history, a human-machine collaborative battle fleet that will confound our enemies.
The Navy is experimenting with a widening menagerie of novel aerial drones, such as a tube-launched rotary-wing drone called the Nomad, which was launched off of the destroyer Pinckney in2016. Another is the hybrid flying-swimming Glider, a drone that can deploy from a plane, fly along the surface of the water, and then submerge to a depth of 200 meters.
Flight-testing for a new version of Glider is scheduled for later this year, and the Naval Research Laboratory expects to a full demonstration in 2019.
The new Navy roadmap argues that the service's adoption of unmanned and robotic capabilities must move far more quickly than it buys human-operated planes, boats, and ships. It outlines steps to accelerate their building, buying and deploying.
One key is moving away from a “platform-centric model” — think big, expensive ships that only serve one role. Instead, envision small, cheap robots that can be robustly networked and easily configured to new tasks.
“The Navy must evolve from today's platform-centric, uncontested-environment [unmanned systems] operating concept to the concept of a platform-agnostic force,” it says. “A cross-domain, distributed, netted, self-healing, highly survivable, and collaborative communications network made of manned and unmanned nodes will enable multi-domain communications. These nodes will fuse big data to interpret the environment, share relevant information, and introduce increased risk, uncertainty, and mistrust in the adversary's systems.”

The DoD needs data-centric security, and here’s why
Drew Schnabel The U.S. Department of Defense is set to adopt an initial zero-trust architecture by the end of the calendar year, transitioning from a network-centric to a data-centric modern security model. Zero trust means an organization does not inherently trust any user. Trust must be continually assessed and granted in a granular fashion. This allows defense agencies to create policies that provide secure access for users connecting from any device, in any location. “This paradigm shift from a network-centric to a data-centric security model will affect every arena of our cyber domain, focusing first on how to protect our data and critical resources and then secondarily on our networks,” Vice Adm. Nancy Norton, director of the Defense Information Systems Agency and commander of the Joint Force Headquarters-Department of Defense Information Network, said at a virtual conference in July. How does the Pentagon's AI center plan to give the military a battlefield advantage? The Pentagon's artificial intelligence hub is working on tools to help in joint, all-domain operations as department leaders seek to use data to gain an advantage on the battlefield. Andrew Eversden To understand how the DoD will benefit from this new zero-trust security model, it's important to understand the department's current Joint Information Environment, or JIE, architecture; the initial intent of this model; and why the JIE can't fully protect modern networks, mobile users and advanced threats. Evolving DoD information security The JIE framework was developed to address inefficiencies of siloed architectures. The goal of developing a single security architecture, or SSA, with JIE was to collapse network security boundaries, reduce the department's external attack surface and standardize management operations. This framework helped ensure that defense agencies and mission partners could share information securely while reducing required maintenance and continued infrastructure expenditures. Previously, there were more than 190 agency security stacks located at the base/post/camp/station around the globe. Now, with the JIE architecture, there are just 22 security stacks centrally managed by the Defense Information Systems Agency to provide consistent security for users, regardless of location. “This paradigm shift from a network-centric to a data-centric security model will affect every arena of our cyber domain, focusing first on how to protect our data and critical resources and then secondarily on our networks,” Vice Adm.

Previously, there were more than 190 agency security stacks located at the base/post/camp/station around the globe. Now, with the JIE architecture, there are just 22 security stacks centrally managed by the Defense Information Systems Agency to provide consistent security for users, regardless of location. Initially, the JIE was an innovative concept that took the DoD from a highly fragmented architecture, in which each agency managed its own cybersecurity strategy, to an architecture in which there is a unified SSA. However, one of the early challenges identified for the JIE was managing cloud cybersecurity as part of the SSA. The components in the JIE — the Joint Regional Security Stacks family's internet access points and cloud access points — have traditionally focused on securing the network, rather than the data or user. As more DoD employees and contractors work remotely and data volumes increase, hardware cannot scale to support them. This has created ongoing concerns with performance, reliability, latency and cost. A cloud-first approach In response, the DoD leverages authorized solutions from the Federal Risk and Authorization Management Program, and it references the Secure Cloud Computing Architecture guidance for a standard approach for boundary and application-level security for impact Level 4 and 5 data hosted in commercial cloud environments. The purpose of the SCCA is to provide a barrier of protection between the DoD Information Services Network and the commercial cloud services that the DoD uses while optimizing the cost-performance trade in cybersecurity. Defense agencies are now exploring enterprise-IT-as-a-service options to move to cloud, and reduce the need for constant updates and management of hardware. Through enterprise-IT-as-a-service models, defense agencies will be able to scale easily, reduce management costs and achieve a more competitive edge over their adversaries. Before the pandemic hit, defense agencies were already moving to support a more mobile workforce, where employees can access data from anywhere on any device. However, a cyber-centric military requires security to be more deeply ingrained into employee culture rather than physical protection of the perimeter. The next evolution to secure DISA and DoD networks is to embrace a secure access edge model with zero-trust capabilities. The SASE model moves essential security functions — such as web gateway firewalls, zero-trust capabilities, data loss prevention and secure network connectivity — all to the cloud. Then, federal employees have direct access to the cloud, while security is pushed as close to the user/data/device as possible. SP 800-27, zero-trust guidance from the National Institute of Standards and Technology, provides a road map to migrate and deploy zero trust across the enterprise environment. This guidance outlines the necessary tenants of zero trust, including securing all communication regardless of network location, and granting access on a per-session basis. This creates a least-privilege-access model to ensure the right person, device and service have access to the data they need while protecting high-value assets. As the DoD transforms the JIE architecture to an as-a-service model with zero-trust capabilities, defense agencies will experience cost savings, greater scalability, better performance for the end user and war fighter, improved visibility, and control across DoD networks — and ultimately a stronger and more holistic cybersecurity capability moving forward. https://www.c4isrnet.com/opinion/2020/09/29/the-dod-needs-data-centric-security-and-heres-why/

As Ukraine braces for a major Russian offensive, its 'drone hunters' fight to defend its cities | CBC News
They stand in silent watch around key Ukrainian cities — the soldiers who call themselves the “drone hunters.” This week, CBC News was allowed access to the Ukrainian military's short-range air defence system outside of Kyiv. The system was assembled to shoot down low-flying aircraft targeting Ukraine's population centres — most of them Iranian-made kamikaze drones packed with explosives.
