By: Jen Judson WASHINGTON — The U.S. Army's interim short-range air defense system, which will urgently fill a capability gap identified a few years ago in the European theater, has crystallized. The Army had already decided the Interim Maneuver-Short-Range Air Defense system would be developed around its Stryker combat vehicle, but it has now chosen Leonardo DRS to supply a mission equipment package that will include Raytheon's Stinger vehicle missile launcher, according to Col. Chuck Worshim, program manager for cruise missile defense systems with the Army's Program Executive Office Missiles and Space, who spoke to Defense News on June 28. General Dynamics Land Systems — which produces the Stryker — will be the platform integrator for the IM-SHORAD system, he added. The Army went through a selection process through the Department of Defense Ordnance Technology Consortium to determine the best collection of vendors to build prototypes. A Boeing-GDLS team was a front-runner for an interim SHORAD mission package, unveiling before any other vendor a solution in August 2017 at the Space and Missile Defense Symposium in Huntsville, Alabama. Using an Avenger system on top of the Stryker, which was the team's solution, sought to take what was already in the Army's inventory to create a system. And a SHORAD demonstration at White Sands Missile Range, New Mexico, last September saw more possibilities for the interim solution including Rafael's Iron Dome and South Korean defense firm Hanwha's Flying Tiger. But a dark horse emerged at the Association of the U.S. Army's Global Force Symposium, also in Huntsville, in March. Leonardo DRS showed an unassuming small-scale mock-up of its concept at its booth at the symposium that featured its partner Moog's Reconfigurable Integrated-weapons Platform. The platform would provide a choice of sights, direct-fire weapons and missiles, Ed House, DRS Land Systems' business development manager, told Defense News at the show. The system would be able to integrate both Stinger and Longbow Hellfire missiles, requirements for the service's IM-SHORAD solution. It also would come equipped with a complement of direct-fire weapons and sights to include the M230 chain gun and the 7.62mm coaxial machine gun. But the solution also has non-kinetic defeat capabilities and Rada's onboard multimission hemispheric radar. And that dark horse has won the opportunity to provide the mission equipment package for the IM-SHORAD prototype program. The system will also have Hellfire rails as well as an onboard sensor, according to Worshim. The Army decided to choose DRS to provide the mission equipment package because of the flexibility of its reconfigurable turret, which allows for growth opportunities should the threat change or something else change that requires a new interceptor or another capability, Worshim said. The solution also posed less intrusion to the existing Stryker platform, he added, and provided an increased level of protection as the crew reloads ammunition, which can be done under armor. While the Avenger solution was deemed technically acceptable and met requirements, one of the reasons the Army decided against using the Avenger on Stryker as the solution was because the government felt it would require major modifications to the Stryker, according to Worshim. The Army has a desire to keep the Stryker as common across the fleet as possible, Worshim said. Boeing was also looking to the government to supply Avenger turrets, of which a limited amount of those exist readily in the service's inventory, which would have been problematic when considering the Army's goal to deliver 144 IM-SHORAD systems by fiscal 2022, he explained. Now that vendors have been selected, the Army will move into a negotiation period expected to wrap up in mid- to late July. The service expects to officially award the contract to build nine prototypes by Aug. 31, but has the intention to possibly move that date up, Worshim said. Once the contracts are solidified, DRS will provide the first mission equipment package, complete with a new digital Stinger missile launcher in February 2019. Then GDLS will fully integrate the SHORAD prototype by April 2019. The final prototypes will be delivered to the service by the first quarter of fiscal 2020. As the prototypes are coming along, the Army will conduct prototype testing to see if the systems are meeting requirements. “From there, the Army will decide if this solution truly meets requirements in this respect,” Worshim said. If the solution does meet requirements, production efforts to build 144 systems — a total of four battalions — will move forward. The Army's goal is to provide the first battery no later than the fourth quarter of 2020, but that will depend on funding. If funding is lower than expected, the Army will deliver the first platoon by about that time, according to Worshim. The service has moved from receiving a directed requirement in late February 2018 to selecting vendors for the IM-SHORAD solution in just about four months, which, Worshim noted, is moving at “lightning speed” for a typical acquisition process. The hope is the process to build an IM-SHORAD solution will be used as a model for Army procurement that incorporates the “fly before you buy” concept and creates a way to rapidly understand capabilities moving forward, he said. https://www.defensenews.com/land/2018/06/28/us-armys-interim-short-range-air-defense-solution-crystallizes/

Mark Pomerleau At air bases across Europe, networks are under attack. Malicious hackers have gained access to sensitive systems, information, controls and critical infrastructure. But cyber operators from U.S. Cyber Command, in concert with Five Eyes partners, have been called in to thwart these attempts in real time. This was the main scenario for this year's capstone cyber training exercise put on by Cyber Command, Cyber Flag 20-2. The exercise, which took place June 15-26 and was exclusively defensive in nature, saw more than 500 participants and 17 teams participating from five countries across nine time zones, and it included America's National Guard, the U.S. Energy Department and the Five Eyes alliance — Australia, Britain, Canada, New Zealand and the U.S. Australia, however, did not participate during this iteration. Officials told reporters this week that the purpose of Cyber Flag 20-2 was to continue building the community of defensive cyber operations and to improve the overall capability of the Five Eyes countries to defend against cyber aggressors. The drill involved teams defending IT and operational security networks against a live, opposing force trying to disrupt, deny and degrade the air bases' operations. The networks under attack were industrial control systems simulated to generate network traffic for an aviation fuel farm, power grid, air traffic control radars and electronic access control systems. The attacks came in the form of malware that targeted devices responsible for fuel and power. But the unique aspect of this year's exercise, as C4ISRNET previously reported, was the use of a new remote cyber training tool called the Persistent Cyber Training Environment. PCTE is an online client that allows Cyber Command's cyber warriors, as well as partner nations, to log on from anywhere in the world to conduct individual or collective cyber training as well as mission rehearsal, which to date had not existed for the cyber force as it does for physical troops. The program is run by the Army on behalf of the joint cyber force. The platform not only allowed the exercise to continue as planned amid the coronavirus pandemic, but it enabled collaboration and simultaneous training across the world. A new way to train Officials say PCTE is providing Cyber Command with an entirely new way to train cyber forces, which previously was difficult given a lack of infrastructure and the time needed to set up ranges and scenarios. It also allows Cyber Command and military units to conduct more frequent training. Cyber Flag typically was Cyber Command's largest and only holistic tactical training event, held annually during June. For units, aside from Cyber Flag, there were no other ways to stay sharp on their skills unless they built their own environments. Now, Cyber Command plans to hold more exercises, with Cyber Flag 20-3 occurring in the fall. “The delivery of the Persistent Cyber Training Environment absolutely allows us to increase the frequency and the complexity of exercises that are conducted by the command itself,” Coast Guard Rear Adm. John Mauger, director of exercises and training at Cyber Command, told reporters. “Going forward, I would expect you to see a series of exercises throughout the year where we are reaching out to the different teams to test their capabilities or to focus on specific issues that are of concern or interest to us. “Going forward, we're going to get the benefits of both those distributed exercises along with increasingly complex exercises as PCTE is instantiated across both the secret network and the top-secret network.” Scenarios and environments can be stored, saved, reused and modified if needed in the system for later exercises. Smaller units will also be able to leverage these scenarios to practice whenever needed. The PCTE virtual environment for this year's exercise included 25 interconnected ranges of more than 3,000 virtual machines — a high-fidelity network that simulated and emulated open internet traffic with more than 4,000 static websites that store and share data. The simulated air base networks created in PCTE had fully configured Windows active directory domains with over 100 nodes running more than 10 types of major operating systems, along with 35 simulated user control workstations actively surfing the internet and using Microsoft Office products to access, create and transfer files. Moreover, officials also explained PCTE can be integrated into larger, multi-combatant command-type exercises to simulate the cyber effects, such as Global Lightning and its companion Cyber Lightning. Global Lightning is an annual global exercise run by Strategic Command to test integration across several geographic and functional combatant commands. Cyber Lightning is Cyber Command's portion to the exercise. “We think that is the next evolution of the Persistent Cyber Training Environment and how we take to the tier 1 exercises, incorporate cyber effects. They're no longer white-carded,” Col. Tanya Trout, Cyber Command's PCTE director and acting director of the Joint Cyber Training Enterprise, told reporters. White carding involves telling exercise participants that a certain action has occurred. This was typical of cyber effects, given it was difficult to realistically simulate them, which diminished the training value in exercises because participants didn't experience the full breadth of these actions. Now, these activities can play a real role in exercises increasing the overall fidelity of training across the joint force and continuity of all operations of warfare. The system will also be able to be used for mission rehearsals. A Cyber Command official said the force can input prior operations, such as those used against the Islamic State group, to train against. Additionally, they'll be able to upload to the platform malware discovered in operations. The PCTE program office, which is in the prototyping phase despite delivering the first portion to Cyber Command in February 2020, also learned valuable lessons in Cyber Flag. Officials said the two-week exercise provided the program office with six months' worth of data it can use to make significant improvements. Prior to the February delivery, the program office leveraged several smaller-scale training events at the unit level to incrementally increase capabilities and scalability as well as help geographically dispersed teams prepare for tier 1 exercises like Cyber Flag. Overall, officials are happy with how the system performed in its first tier 1 exercise, pointing to little to no latency issues, though there were periodic improvement tickets. “What we found through the rapid development and use of the Persistent Cyber Training Environment is that we really have a unique capability to move forward with,” Mauger said. https://www.c4isrnet.com/dod/cybercom/2020/06/25/this-training-tool-could-be-the-answer-to-stop-mass-cyberattacks
