    US Army’s top uniformed IT official lays out priorities for new office

    Andrew Eversden WASHINGTON — The U.S. Army's new top military IT official has its eyes on several priorities to ensure that the service is prepared for multi-domain operations. Lt. Gen. John Morrison, the Army's first deputy chief of staff for the G-6, a new position created after the Army announced it would be splitting its CIO/G-6 office over the summer, told reporters Tuesday that his new office will focus on strategy, network architectures, and implementation of command, control, communications, and cyber operations efforts. To achieve that, Morrison laid out four pillars that will shape the role of the new G-6 office, which reached initial operating capability after he took over in August. The four pillars are establishing a unified network, positioning cyber and signal forces for multi-domain operations, reforming the cybersecurity process, and driving efficient and effective investments across the network and cyber. The unified network pillar is focused on vertical integration of the tactical network and enterprise networks to create a unified network that can meet the globally dispersed warfighting operations of the service. Right now, Morrison said, the enterprise network is focused on modernizing bases, posts, camps and installations, while the tactical network is centered around brigade combat teams. The unified network will be “imperative” for multi-domain operations, Morrison said. His office will work with Program Executive Office Enterprise Information Systems; PEO Command, Control, Communications-Tactical; and the Network Cross-Functional Team to establish the unified network he said the Army needs to enable Joint All-Domain Command and Control. “We break down the individual theater architectures, and we make it easy for formations that are actually in [the contiguous United States] to rapidly deploy to any area of operations and immediately plug in and start conducting operations, whether that's in competition or conflict,” Morrison said. “That needs to be ... our goal.” As for aligning cyber and signal forces for multi-domain operations, Morrison said that he will be looking at the training, talent management and operational frameworks while adjusting them over time to ensure those soldiers are used effectively during future battles. “That means making sure that we have signal and cyber, underpinned by intelligence, operating in a combined arms fashion in cyberspace to include electromagnetic spectrum,” Morrison said. The three-star also wants to take a “hard look” at the service's risk management framework (RMF) as part of reforming and operationalizing its cybersecurity process. He wants to move the Army away from a bureaucratic system with intermittent reviews to a system where cybersecurity is baked into a system before it's added to the network, then going back “periodically” to make sure there are no new vulnerabilities to the system. As the service works toward enabling multi-domain operations, Morrison is also focused on ensuring that the service is making effective and efficient investments in its network and cyber infrastructure so that it can make the JADC2 concept a reality. For example, Morrison said, his team is looking at what the joint force is doing with cyber so the Army makes investments to develop cyber capabilities that the service needs while ensuring it has links back to the joint force. It's especially important for the Army to be meticulous with its cyber and network investments as the Department of Defense as a whole prepares for flat budgets as the government funds are increasingly directed toward recovery from the COVID-19 pandemic, Morrison said. “We are probably entering into a time where budgets may not be all that they have been in the past,” he said. “And quite frankly, we owe it to taxpayers to force ourselves to be efficient and effective.” Before former Army CIO/G-6 Lt. Gen. Bruce Crawford retired, he told reporters that the Army split the CIO/G-6 office to take better advantage of technology, saying that the way his office was structured had become outdated as technology advanced. The Army has yet to nominate a new CIO, but Morrison will work closely with the next official named to that position, he said. “Think of it in this way, the CIO establishes the policies," Morrison said. "We're responsible for the planning and the actual implementation of those policies, and then supporting Army organizations worldwide as they go out and actually execute the policies.” https://www.c4isrnet.com/battlefield-tech/it-networks/2020/10/27/us-armys-top-uniformed-it-official-lays-out-priorities-for-new-office/

    Army Space and Missile Defense Command is getting a new leader

    By: Jen Judson HUNTSVILLE, Alabama — Maj. Gen. Daniel Karbler, who is the chief of staff at U.S. Strategic Command, will depart Offutt Air Force Base, Nebraska, to take up command at Army Space and Missile Defense Command in Redstone Arsenal, Alabama, several sources have confirmed to Defense News. Prior to his job at STRATCOM, Karbler was in charge of U.S. Army Test and Evaluation Command and was also the director of joint and integration efforts within the Army G-8. Karbler's nomination appears in the Congressional Record on July 31 but does not state the position for which he is nominated. He would receive his third star if confirmed. The two-star general has an extensive background in air and missile defense stemming back to the beginning of his career. Karbler commanded two different batteries in the 5th Battalion, 7th Air Defense Artillery Regiment, 32nd Army Air and Missile Defense Command in the European theater. He also commanded the 3rd Battalion, 43rd Air Defense Artillery Regiment, 32nd AAMDC at Fort Bliss, Texas; the 31st Air Defense Artillery Brigade, 32nd AAMDC at Fort Sill, Oklahoma; and the 9th AAMDC at Fort Shafter, Hawaii. Karbler is a U.S. Military Academy graduate. He commissioned as a second lieutenant in the air defense artillery branch. Karbler will take the reigns from Lt. Gen. James Dickinson, who is tapped to become the deputy commander at the newly created U.S. Space Command. Defense News first reported Aug. 6 that Dickinson was nominated for the position while reporting from the Space and Missile Defense Symposium in Huntsville, Alabama. https://www.defensenews.com/digital-show-dailies/smd/2019/08/06/army-space-and-missile-defense-command-is-getting-a-new-leader/

  • Future US Navy weapons will need lots of power. That’s a huge engineering challenge.

    Future US Navy weapons will need lots of power. That’s a huge engineering challenge.

    David B. Larter WASHINGTON ― The U.S. Navy is convinced that the next generation of ships will need to integrate lasers, electromagnetic rail guns and other power-hungry weapons and sensors to take on peer competitors in the coming decades. However, integrating futuristic technologies onto existing platforms, even on some of the newer ships with plenty of excess power capacity, will still be an incredibly difficult engineering challenge, experts say. Capt. Mark Vandroff, the current commanding officer of the Carderock Division of the Naval Surface Warfare Center and the former Arleigh Burke-class destroyer program manager who worked on the DDG Flight III, told the audience at last week's American Society of Naval Engineers symposium that adding extra electric-power capacity in ships currently in design was a good idea, but that the weapons and systems of tomorrow will pose a significant challenge to naval engineers when it comes time to back-fit them to existing platforms. “Electrical architecture on ships is hard,” Vandroff said. Vandroff considered adding a several-megawatt system to a ship with plenty of power to spare, comparing it with simultaneously turning on everything in a house. “When you turn everything on in your house that you can think of, you don't make a significant change to the load for [the power company],” Vandroff explained. “On a ship, if you have single loads that are [a] major part of the ship's total load, [it can be a challenge]. This is something we had to look at for DDG Flight III where the air and missile defense radar was going to be a major percentage of the total electric load ― greater than anything that we had experienced in the previous ships in the class. That's a real technical challenge. “We worked long and hard at that in order to get ourselves to a place with Flight III where we were confident that when you turned things on and off the way you wanted to in combat, you weren't going to light any of your switchboards on fire. That was not a back-of-the-envelope problem, that was a lot of folks in the Navy technical community ... doing a lot of work to make sure we could get to that place, and eventually we did.” In order to get AMDR, or SPY-6, installed on the DDG design, Vandroff and the team at the DDG-51 program had to redesign nearly half the ship — about 45 percent all told. Even on ships with the extra electric-power capacity, major modifications might be necessary, he warned. “We're going to say that in the future we are going to be flexible, we are going to have a lot of extra power,” Vandroff said. “That will not automatically solve the problem going forward. If you have a big enough load that comes along for a war-fighting application or any other application you might want, it is going to take technical work and potential future modification in order to get there.” Even the powerhouse Zumwalt class will struggle with new systems that take up a large percentage of the ship's power load, Vandroff said. “Take DDG-1000 ― potentially has 80-odd megawatts of power. If you have a 5- or 6-megawatt load that goes on or off, that is a big enough percentage of total load that it's going to be accounted for. Electrical architecture in the future is still an area that is going to require a lot of effort and a lot of tailoring, whatever your platform is, to accommodate those large loads,” he said. In 2016, when the Navy was planning to install a rail gun on an expeditionary fast transport vessel as a demonstration, service officials viewed the electric-power puzzle as the reason the service has not moved more aggressively to field rail gun on the Zumwalt class. Then-director of surface warfare Rear Adm. Pete Fanta told Defense News that he wanted to move ahead with a rail gun demonstration on the JHSV because of issues with the load. “I would rather get an operational unit out there faster than do a demonstration that just does a demonstration,” Fanta said, “primarily because it will slow the engineering work that I have to do to get that power transference that I need to get multiple repeatable shots that I can now install in a ship.” https://www.defensenews.com/naval/2018/06/24/future-navy-weapons-will-need-lots-power-thats-a-huge-engineering-challenge/
