The Army wants drones that make their own networks
Eventually, the Shadow will come to pass. The Army is looking for replacements to the venerable drone, first flown in 1991, through its Future Tactical UAS program. In the nearly three decades since, every aspect of drone technology has seen some improvement, including materials used, sensors to communication hardware and software, and even the batteries that power those computers and sensors. The Army has also seen the limitations of what it can and cannot do with a drone that has to either operate from a runway or be launched from a rail and caught on a hook. Into this mix of requirements and new possibility flies the Resolute Eagle, made by PAE ISR, complete with an ad hoc network system from Persistent Systems.
The Army is looking at a range of drones for possible Shadow replacement, and the Resolute Eagle will have to compete with designs as varied as Insitu's ScanEagle and Integrator, Martin UAV's V-Bat, Endeavor Robotics' Firstlook and SUGV, QinetiQ's Talon and Dragon Runner. This is a somewhat crowded field, and to compete in it Resolute Eagle has a VTOL model, which essentially grafts booms with rotors to the drone's wings, allowing it to take off and land like a quadcopter. The VTOL configuration is listed as having 12 hours of endurance, compared to 18 hours for the purely fixed-wing version, and the booms are detachable, giving some flexibility when forward deployed.
“Our reconfigurable platform (from fixed wing to VTOL), large payload capacity, and reduced ground support equipment requirements offers significant mission flexibility, both as a Shadow replacement for BCT expeditionary forces and as a complement to the existing platforms currently in use for military and civilian uses,” said Beth Beach, vice president of business development at PAE ISR.
Besides military customers, PAE ISR is targeting the Resolute Eagle at a broad range of law enforcement, the Department of Homeland Security, humanitarian and commercial missions, according to Beach. Its ISR abilities could be used for pipeline and railway inspection, as well as evaluating the area after a natural disaster and looking for people in search and rescue. Key to this is an ability to operate beyond line of sight through satellite communications.
Relying on satellites is a safe bet for civilian applications going forward, but across the Pentagon people are looking for other ways to retain or set up communications networks on the battlefield in the event that the satellite communication becomes untenable. One way to ensure communication via drones is equipping the drones with tools for an ad hoc network. For the Resolute Eagle, that comes in the form of Persistent Systems' MPU5 Wave Relay mobile ad hoc networking (MANET).
“The beauty of the MANET is that it can be setup and deployed with ease,” said Robert Regan, sales engineer at Persistent Systems. “Users can leave and enter the network seamlessly due to its self-healing and self-forming nature. When dealing with RF it is important to remember that every use case is different. So when dealing with distances there are lots of variables that can affect distance: RF environment, terrain, frequency band selected and antenna selection, just to name a few. With our auto-tracking antenna system we have reached out to UAV's at 130 miles.”
This MANET is platform agnostic, and could operate not just from Resolute Eagle drones, but from multiple drones, ground robots, and in systems carried by people on foot. To keep the communication secure, MPU5 radio operates with AES 256-bit Suite B encryption, ensuring that only those with the right decryption tools (or the proper key) can access it.
As the Army looks for its Shadow replacement, the capabilities on offer are what's most compelling, since they suggest the full range of possibility for a new mid-sized tactical drone. Crossing over from offering to contract is a not insignificant task, and in November 2018 US Naval Air System Command awarded PAE ISR a $173 billion contract for ISR services by Resolute Eagle.

Navy Creating Attack Sub Aggressor Unit to Train to Fight Against Russia, China
By: Megan Eckstein ARLINGTON, Va. — The U.S. Navy submarine force is creating an aggressor squadron as one initiative to ensure all subs are combat-ready as the service trains to take on China and Russia, the commander of Naval Submarine Forces said on Wednesday. Vice Adm. Charles Richard, who took command in August, drew attention during the change of command ceremony by telling the force to “prepare for battle.” He has backed up those words with actions in the months since, moving ahead with a plan – updated in March to reflect the National Defense Strategy – that includes refocusing training and certification on combat and developing new tools and concepts to support high-end warfighting. The plan – called the Commander's Intent for the United States Submarine Force and Supporting Organizations – led to an overhaul of training for the attack submarine force, Richard said today while addressing the Naval Submarine League at its annual conference. “We have restructured and retuned the fast attack training period to ensure that we're ready for that high-end fight, including restructuring what we used to call the Tactical Readiness Evaluation, and it is now a Combat Readiness Evaluation to ensure we're focused on warfighting,” he said. “We've updated the deployment certification process to eliminate duplication, put the right focus in the right place. I'll tell you that I am driving to put competition in everything we do inside the submarine force. I want to produce winners and losers just like we do in battle; it does you no good to be at standards if your opponent is more at standards than you are. You still lose, and in this competition, you may not come home.” The new aggressor squadron fits in with the desire to create more high-end sub-on-sub competitions and ensure the Navy is ready to win. Richard said the plan mimics what the naval aviation community has at “Top Gun.” Navy spokeswoman Cmdr. Sarah Self-Kyler told USNI News at the event that, unlike Top Gun, the squadron won't have its own submarines dedicated to training the squadron and fighting other submarines in training events. Instead, the squadron will include a yet-to-be-determined number of personnel – which Richard said would include active and reserve sailors and civilians – and that personnel would get to work with submarines and sub crews as allowed by operational and training schedules. Richard, calling the new group “a cadre that does nothing but emulate red in all of our training and certification exercises, said “we're taking a page from naval aviation and we're establishing an aggressor squadron with a team that will become experts in employing our adversaries' potential capabilities and then set them up to be able to go head-to-head with our units so that we're always training against what we think is the highest fidelity simulation I can give them in terms of what they might be able to expect when they go into combat.” The Commander's Intent plan also outlines an Undersea Rapid Capability Initiatives (URCI) program that Richard said not only delivers “stuff” but also concepts of operations, tactics, maintenance strategies and more. “I can't go into a lot of detail given the nature of the work – it is classified – but I am able to tell you that we are working on 26 major future projects, including the Navy's number-one priority of strategic deterrence; 13 URCIs; 11 operational initiatives; and a series of advanced workshops and military exercises designed to expand our capabilities in the undersea domain. We are pursuing next-generation weapons, multi-domain sensors, comms systems, navigation aids, and unmanned and autonomous technologies. In some cases, these capabilities are revolutionary and will inform future programs of record.” Full article: https://news.usni.org/2018/11/08/submarine-forces-china-russia
