Is this the Marine Corps' next amphibious combat vehicle?
By: Todd South
MARINE CORPS BASE QUANTICO, Va. ― The winner of a contract to develop the Marine Corps new amphibious combat vehicle, the first of its kind in four decades, showcased a potential variant that would give commanders eyes on all areas of the littoral battlefield, on-board drones and targeted hand offs to any ACV in their formations.
BAE Systems guided reporters through the interior of the vehicle, on display at this year's Modern Day Marine Expo in Quantico, Virginia, on Tuesday.
The variant isn't one that the Marines have yet requested, but John Swift, program director for BAE's amphibious vehicles, said the model was an effort to showcase what's possible with the new vehicle.
Marines selected the BAE version earlier this year over SAIC's proposed vehicle. Swift noted that decision keeps BAE as the sole company providing such vehicles to the Corps since 1941.
They've got to build 30 vehicles by the end of next summer, Swift said. Those vehicles will then go through testing before modifications and the composition of the fleet is decided. Marines want at least two variants as production begins in the next two years: a turreted assault vehicle and a command and control vehicle.
As of now, the Corps' official numbers call for 704 ACVs for the fleet when full rate production begins in 2022. That number is planned to be completed within six years, Swift said.
The composition of the fleet is still undecided, so the initial 30 vehicles delivered for testing will be basic platforms.
But that was before an announcement reported by Defense News this week that the survivability upgrade contract for the existing AAV fleet of an estimated 392 AAVs was cancelled.
The move is in line with larger National Defense Strategy aims to ramp up modernization by prioritizing money for those programs rather than legacy platforms.
Marine Corps Program Executive Office for Land Systems spokesman Manny Pacheco told reporters at this week's expo that the early version, or ACV 1.1 outperformed expectations and delivery of the new vehicles would not take much longer than the planned upgrades, which could shorten the calendar.
The deliveries were about six months apart, he said. Meaning that the brand-new vehicles would arrives shortly after the upgraded vehicles were planned.
Swift and Pacheco said separately that the ACV 1.1 was able to both launch and recover, meaning return to ship. That wasn't an expectation until later versions, which sped up the capability development of the new vehicle, giving the Marines other options in how they would pursue modernizing the fleet.
In a question and answer posting about the ACV by the Marine Corps Combat Development Command, officials at the time said they would continue the upgrade program even if the early ACV versions achieved a “self-deployable capability.”
The posting noted that the upgraded AAVs will “address capability gaps that need to be closed as soon as possible.”
It went on to say that the aged AAV fleet also accounts for one-third of the Corps' lift capacity and “will need to remain operationally effective in the force until their replacements are procured.”
Later in production there's also interest in building a recovery ACV, Swift said.https://www.marinecorpstimes.com/news/your-marine-corps/2018/09/27/is-this-the-marine-corps-next-amphibious-combat-vehicle
The new ACV has a host of differences and capabilities not on the more than 40-year-old AAVs but most immediately noticeable is it is an eight-wheeled vehicle. Gone are the treads of the tracked AAV.
When asked about tire performance by reporters, Swift said that in testing the ACV was able to travel another 30 km with three debilitated tires.
The same questions and answers list had several reasons for wheels over tracks:
Greater mobility in complex, littoral terrain;
• Increased IED protection (2X).
• Reduced fuel consumption (<1/2 fuel consumption).
• Greater reliability (improved mean time between failure).
• Reduced signature and smaller profiles (a critical survivability factor in a G-RAMM environment).
• Increased dispersion of personnel among more vehicles (a critical risk reduction factor).
• The design margins to allow for a family of vehicles of various configurations (personnel, command, and recovery variants; potentially others ie: indirect-fire, anti-armor in the future).
• Significantly reduced cost.
• Less technological risk.
• Nearer-term availability.
• Greater weight growth and freeboard capacity.

France: La question d'un 2e porte-avion sera tranchée en 2025
La décision de doter ou non la France d'un deuxième porte-avions sera prise dans le cadre de la prochaine loi de programmation militaire, soit à partir de 2025. La Marine nationale plaide pour la construction d'un nouveau navire pour permettre à la France d'assurer une "permanence à la mer". La décision de doter ou non la France d'un deuxième porte-avions sera prise dans le cadre de la prochaine loi de programmation militaire, soit à partir de 2025, a expliqué dimanche 9 septembre la ministre des Armées Florence Parly. Mis en service en 2001, l'unique porte-avions français, le Charles de Gaulle, "a vocation à terminer sa vie active autour de 2040", a-t-elle rappelé lors de l'émission Europe 1/CNews/Les Échos "Le grand rendez-vous". "C'est donc dès maintenant, dans le cadre de cette loi de programmation militaire (2019-2025, ndr), que nous lançons des études pour réfléchir à ce que doit être ce nouveau porte-avions", a-t-elle rappelé. Mais "lorsqu'on lance des études pour un nouveau modèle de porte-avions, on laisse ouverte la question de savoir s'il en faut un ou s'il en faut deux". Le Charles de Gaulle en rénovation "C'est la prochaine loi de programmation militaire, celle qui interviendra au-delà de 2025, qui devra déterminer les moyens pour assurer la construction de ce ou ces porte-avions et de définir le nombre de ces navires", a-t-elle conclu. Le porte-avions Charles de Gaulle subit depuis début 2017 à Toulon une vaste rénovation longue de 18 mois, qui doit redonner une seconde vie à ce b'timent pour les 20 prochaines années. La Marine nationale plaide pour la construction d'un deuxième porte-avions pour permettre à la France d'assurer une "permanence à la mer".

DoD releases first new cyber strategy in three years
By: Mark Pomerleau In its first formal cyber strategy document in three years, the Department of Defense said it would focus its cyber efforts on China and Russia and use the Pentagon's cyber capabilities to collect intelligence as well as to prepare for future conflicts. According to an unclassified summary and fact sheet released Sept. 18, the documents lay out a vision for addressing cyber threats and addresses the priorities of the department's National Security Strategy and National Defense Strategy, which focused on a new era of strategic great power competition. “The United States cannot afford inaction,” the summary reads. It notes that China and Russia are conducting persistent campaigns in cyberspace that pose long term risk. The documents also say that China is eroding the U.S. military's ability to overmatch opponents and that Russia is using cyber-enabled information operations to influence the U.S. population and challenge democratic processes. The DoD's strategy comes on the heels of other major movements in cyberspace from the department. These include the elevation of U.S. Cyber Command to a full unified combatant command — which affords new and exquisite authorities — the full staffing of Cyber Command's cyber teams, an update to DoD's cyber doctrine and new authorities delegating certain responsibilities from the president to DoD to conduct cyber operations abroad. The summary's lists five objectives for DoD's cyberspace strategy: - Ensuring the joint force can achieve its missions in a contested cyberspace environment; - Strengthening the joint force by conducting cyberspace operations that enhance U.S. military advantages; - Defending U.S. critical infrastructure from malicious cyber activity that alone, or as part of a campaign, could cause a significant cyber incident; - Securing DoD information and systems against malicious cyber activity, including DoD information on non-DoD-owned networks; and - Expanding DoD cyber cooperation with interagency, industry, and international partners. The strategy also describes the need to remain consistently engaged with this persistent adversary and to “defend forward” as a means of disrupting or halting malicious cyber activity at its source, including activity that falls below the level of armed conflict. While academics have criticized the U.S. response to Russian election interference, the strategy notes that the United States tends to view conflicts through the binary lens of war or peace while competitors such as Russia see themselves constantly engaged in a state of war. U.S. Cyber Command's new leader is taking a different tact. “We've got to act forward outside of our boundaries, something that we do very, very well at Cyber Command in terms of getting into our adversary's networks. That's this idea of persistent engagement, the idea that the adversary never rests, so why would we ever rest,” Gen. Paul Nakasone said during an August dinner hosted by the Intelligence and National Security Alliance. Nakasone also has described the notion of defending forward as enabling forces to act outside the boundaries of the U.S. to understand what adversaries are doing in order to better defend against them. https://www.fifthdomain.com/dod/2018/09/19/department-of-defense-unveils-new-cyber-strategy
