  Lockheed planning big shift away from LCS propulsion system for its future frigate offering

  By: David B. Larter PARIS – Lockheed Martin is planning to shift from its littoral combat ship's water-jet propulsion to a propulsion system that the U.S. Navy is more familiar with for its future frigate offering, Lockheed's vice president for small combatants and ship systems told reporters at the 2018 Euronaval show. As it works through the Navy's requirements for its FFG(X) program, Lockheed is hoping that a more traditional twin-screw design with independent drive trains will entice the service towards its offering. One of the major hang-ups with the design requirements for all the competitors has been requirement that the engineering spaces be separated by a certain number of meters so that if the ship takes damage in one area, the other space should be online to drive the ship. If the design can't meet the spacing requirement, an alternative propulsion unit has to be installed. For Lockheed, the decision was to try and meet the spacing requirement, which is making its FFG(X) offering a bigger ship than the Freedom-variant littoral combat ship. “We felt the more traditional approach to the suite, going with more of the ... port and starboard side, redundant type of propulsion trains, that familiarity would be well received by the Navy. Going to more of a common system sized for the FFG(X),” said Joe DePietro. “It does require the ship to be longer, given those separation requirements and how you plan to stagger your port and starboard configuration of the combining gear/reduction gear, running into a single shaft into a screw on either side. You have to have a certain amount of separation and they have to be fully independent.” As for the system itself, Lockheed is keeping its options open, but is looking hard and combined diesel and gas systems, or even combined diesel and diesel, give the speed requirements for FFG(X), which are well reduced from what they were for the speedy LCS. The fleet has been receptive but mixed on the idea of a straight diesel propulsion system. But the trade-off for gas turbines is less fuel efficiency, which impacts range, DePietro said. In February, the Navy announced that it had awarded design contracts to asked to Huntington Ingalls, Lockheed Martin, Austal USA, General Dynamics Bath Iron Works, and Italian shipbuilder Fincantieri have all been asked to submit mature designs. Lockheed is playing a strong hand going into selection, however, because of its partnership with Fincantieri on the Freedom-variant LCS, which is built at Fincantieri's Marinette Marine shipyard in Wisconsin. Lockheed will either win the award for its modified LCS or it will be a systems integrator for Fincantieri's FREMM, which is another leading competitor for the program. https://www.defensenews.com/digital-show-dailies/euronaval/2018/10/23/lockheed-planning-big-shift-away-from-lcs-propulsion-system-for-its-future-frigate-offering

  Marines cyber forces to grow

  By: Mark Pomerleau The Marine Corps' main cyber war-fighting organization will soon be growing. Maj. Gen. Lori Reynolds, commander of Marine Corps Forces Cyberspace Command, said her force doesn't have the depth to do what the Army is doing in experimenting with integrated offensive and defensive cyber effects at the tactical edge with full brigades. This is one of the reasons the commandant approved expansion at MARFORCYBER, Reynolds told Fifth Domain following her appearance on an AFCEA-hosted panel in early April. “We've got to do that,” she said, referring to what the Army is doing. “We've got to get the rest of the service, Training and Education Command, we've got to give them the skills and the talent, if you will, to think about how do we prepare the rest of the Marine Corps to integrate cyber effectively. Moreover, the Marine Corps created a cyber career field earlier this year and requested 1,000 billets related to cyber/electronic warfare/information operations in the most recent budget to be better postured to fight and win in an increasingly modern battlefield. MARFORCYBER will get around 40 percent of new career field designees to work on the defensive side with just a couple going to the offensive teams, Reynolds said. The Marines have recognized that cyber is going to be a foundational capability in the future with some ingrained organizational structure behind it. “We just really have to get more return on investment ... and what we want to be able to do is continue to increase our proficiency and skills,” Reynolds said. “When you're constantly moving people out of the cyber workforce, you're starting over again all the time. That doesn't work.” Currently, the Marines deployed on the cyber mission force — a joint force that makes up U.S. Cyber Command's cyber warrior cadre — are lateral moves, Reynolds said, or they're working as signals intelligence Marines and they're just in and out of cyber. While the total number of forces on the CMF will stay the same, the types of Marines filling those roles will change, a MARFORCYBER spokeswoman told Fifth Domain. When a communication officer currently working on a team rotates, that billet will be coded as a cyberspace officer and will be filled only by someone in the new cyber career field, they added. The model going forward should be building a “foundation from the ground up of defensive cyber and then maybe start building some of our offensive capability from the defense while we're still flowing SIGINT through the offensive teams,” Reynolds said. This move comes as the Marines, as well as the other services, are going through a bit of a culture shock when it comes to introducing these nontraditional skill sets into the ranks. “I think the commandant is willing to challenge every assumption we've ever made about how we treat these MOS,” Reynolds said. In fact, during recent congressional testimony, Reynolds noted that the commandant often points out “we may end up with a platoon of warrant officers, and that's got to be okay with us.” https://www.fifthdomain.com/dod/marine-corps/2018/04/05/marines-cyber-forces-to-grow/
