US Army begins experimenting with new network tools

WASHINGTON — The U.S. Army's combat capabilities development team kicked off a monthslong experiment last week to test emerging technologies that could be added into the service's tactical network.

The third annual Network Modernization Experiment at Joint Base McGuire-Dix-Lakehurst in New Jersey started July 20 and ends Oct. 2. NetModX provides an opportunity for the Combat Capabilities Development Command's C5ISR Center — or Command, Control, Communication, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance Center — to perform field tests with emerging capabilities that have largely been tested in the lab.

Field tests with simulated threat environments, as opposed to lab tests, are important because technologies react in unexpected ways due to realities like different types of trees or terrain.

This year's theme for NetModX is mission command and command-post survivability, which means participants will focus on technologies that could be fielded in the Army's Integrated Tactical Network Capability Set '23 and Capability Set '25 — future iterations of network tools that the Army plans to deliver to soldiers every two years.

In this year's test, the C5ISR Center is testing communications capabilities that allow for distributed mission command systems across the battlefield “and wider area,” said Michael Brownfield, chief of the future capabilities office at the C5ISR Center.

“We've learned by watching our enemies fight, and we know that to survive on the battlefield, No. 1, they can't be able to see us,” Brownfield told C4ISRNET in an interview. “And No. 2, we have to distribute our systems across the battlefield to give them multiple targets and multiple dilemmas in order to survive.”

NetModX is also testing network resiliency capabilities that could be delivered as part of Capability Set '23. Preliminary design review for the capability set is scheduled for April next year. To test the effectiveness of the resiliency projects the center developed in the lab, the C5ISR Center created a “state-of-the-art red cell” that attacks the network using enemy's tactics, techniques and procedures, according to Brownfield. The goal is to make sure the technology can withstand electronic attacks and allow for continuous operations in contested environments when in the hands of deployed soldiers.

“What resiliency means to us is the network bends, it doesn't break,” Brownfield said. “And the commanders have the information they need and the coordination that they need to fight the battle.”

A modular radio frequency system of systems is undergoing tests, and Brownfield says it will “revolutionize” the fight on the battlefield. The system automatically switches between primary, alternate, contingency and emergency, or PACE, radios by sensing if radio frequencies are being jammed. The system then responds by automatically switching radio channels to allow for seamless communications in a contested environment.

Currently, “it's kind of hard to switch to alternate comms when the person you're talking to is on their primary, not their alternative comms,” Brownfield said. “And the process is very slow. It's human-driven.”

Now, the automatic PACE system senses the environment in milliseconds, he said. At last year's experiment, which focused on network transport capabilities to support precision fires for multidomain operations, the center experimented with radios that could flip to new channels on their own, while launching brute force and other more sophisticated attacks against the radios to see how much stress they could handle before passing data became impossible.

This year will be a little different.

“This year, we're pairing different radios together and see how they can work to actually change the type of modulation schemes that we use to maneuver in cyberspace around for continuous operations while under enemy attack and under contested electronic warfare conditions,” Brownfield said.

One of the top priorities for this year's experiment is allowing for projects leaders to bring their technology into to the field, no matter what stage of development they are in, to be tested in an “operationally relevant environment,” Brownfield said. The team then collects data on how the technology performs and puts it into a database where it can be queried to answer specific performance questions.

“So we can ... ask the database questions like, ‘What was my latency with these two radios at this point in time,' and start to understand the true metrics of how the systems performed in the field,” Joshua Fischer, acting chief of systems engineering, architecture, modeling and simulation at the C5ISR Center, told C4ISRNET. He added that those involved are also looking at network throughput.

    Japan’s Reset Raises Questions Over Big Programs

    Toyko has put the breaks on its Aegis Ashore program, and there are reports its support for the Global Hawk buy may be soft. By PAUL MCLEARYon August 20, 2020 at 4:29 PM WASHINGTON: As Japan undergoes the deepest rethink of its defense posture since the end of the Second World War, some big-ticket acquisition programs appear to be on shaky ground as the country retools to counter a rapidly modernizing Chinese military. Tokyo put the brakes on two planned Aegis Ashore missile defense systems set to be built on the mainland, a surprise June move that came after local communities protested about the powerful radars and possibility that rocket debris could fall on local communities. That reversal on a major $2.1 billion program led to questions over what other changes the government of Shinzo Abe might consider as it retools its defense strategy and considers funneling more money into offensive strike weapons, as opposed to purely defensive systems. Earlier this week, fresh reports emerged from Tokyo that the government might also be reconsidering its purchase of three Global Hawk UAVs, which would provide long-endurance surveillance capabilities. One source with knowledge of the program said, despite the reports, the Japanese government has indicated it supports the Global Hawk program, even in the face of possible divestiture by the US Air Force of its block 30 variants, the same version Northrop Grumman is making for Japan. Despite the moves in Washington, South Korea is still in the process of buying four block 30 Global Hawks, the first of which was delivered in April. Further south, Australia purchased six MQ-4C Tritons — the maritime version of the Global Hawk — with the first three to be delivered between 2023 and 2025. With those allies remaining in the program, and the US flying the drone from Guam on a seasonal basis, the allies have started to build a powerful, long-endurance sensor layer, along with its attendant supply chain. That sort of capability would fit within plans the Indo-Pacific Command pitched to the Trump administration earlier this year to invest billions in joint infrastructure across the region. The proposal has found bipartisan support on Capitol Hill, with the Republican-controlled Senate's version of the annual defense policy bill including $1.4 billion for an Indo-Pacific Deterrence Initiative, while the Democratic-controlled House had $3.6 billion for an Indo-Pacific Reassurance Initiative focused on shoring up allies and partners. A conference committee will have to thrash out the differences and fill in almost all the details this fall. The Japanese Ministry of Defense did not respond to questions on the issue by publication. “Unmanned systems are going to be vital — in particular underwater unmanned systems and also aerial unmanned systems — given that Japan is an archipelago,” Ryo Hinata-Yamaguchi, professor at Pusan National University, said during a virtual event sponsored by the Atlantic Council on Wednesday. “Those are the domains that are most vital to Japan's security. It's really about Japan thinking about what we can afford to do, what we need to do.” https://breakingdefense.com/2020/08/japans-reset-raises-questions-over-big-programs
