In first, France’s aircraft carrier to deploy under NATO command

The move is meant to demonstrate France's commitment to the alliance and to get familiar with NATO command-and-control mechanisms.

    Navy, Marine Corps Racing to Increase Amphibious Fleet as Demand Rises

    By: Ben Werner CAPITOL HILL — The Navy and Marine Corps are running up against a deadline to add more amphibious warships to the fleet before older hulls start retiring, Marine Maj. Gen. David Coffman told lawmakers and shipbuilding industry representatives at a congressional forum Tuesday. Recognizing this is a moment when the Hill is pushing to build more ships faster, Coffman said he's focused on ensuring these new ships are designed to accommodate changing technologies and remain useful for 50 years. “We're trying to make sure we have the full ability to take advantage of a multi-year buy,” Coffman, the director of expeditionary warfare on the chief of naval operations' staff (OPNAV N95), said. Coffman was referring to the possibility of the Navy buying 13 San Antonio-class LPD Flight II ships in a block buy contract. These ships are intended to replace Whidbey Island-class LSD ships. As an example, Coffman cited the need to prepare future ships to handle the networking needs of unmanned and autonomous surface and undersea vehicles, which will be incorporated into the amphibious forces of the future. Unmanned surface and undersea vehicles have the potential to dramatically change the way amphibious forces operate, he said. “We have a moonshot idea for amphibious assault, which says it'll be a long time before you see a Marine step off of something because we're going to go autonomous,” Coffman said. “Get autonomous and unmanned to do a lot of the work.” Also, incorporating the networking needs of the F-35B Lightning II Joint Strike Fighter into ship design is critical to the Marine Corps ability to use the aircraft, Coffman said. Future amphibious assaults will most likely occur in contested, even urban areas. Since the Marine Corps is counting on the F-35 playing an important role securing such contested locations, Coffman wants to continually ask what can be done better and how to improve the ship class' capabilities instead of just settling on a single design. “No one else on the planet can do what we do in the littoral space,” Coffman said. But the needs of the Navy and Marine Corps to perform in the littoral space currently outpaces the nation's amphibious warship capacity, said Rep. Rob Wittman (R-Va.). The Navy's shipbuilding plan, which calls for building a 355-ship fleet, is a good start, but the critical number Wittman said is the 38 amphibious ships included in that plan. Previously, Wittman has criticized the slow pace of the Navy's shipbuilding plan. USS Wasp (LHD-1) is expected to reach the end of its anticipated working life by 2030. The concern is older ships such as Wasp will retire before the Navy reaches the goal of 38 amphibious ships, making it nearly impossible for the shipbuilding pace to ever increase the total number of amphibious hulls in use. “Marines can do almost anything, Wittman said.”But until they can walk on water we better be building them more ships.” https://news.usni.org/2018/07/24/navy-and-marine-corps-racing-to-increase-amphibious-fleet

    Here are a few of the experiments hitching a ride on the Air Force’s secret space plane

    Nathan Strout When the secretive X-37B space plane returns to orbit on May 16, it will be carrying more experiments than it has on any previous mission, including one that will transmit solar energy from space to the ground via microwave energy. "The X-37B team continues to exemplify the kind of lean, agile and forward-leaning technology development we need as a nation in the space domain," said U.S. Space Force Chief of Space Operations Gen. John "Jay" Raymond. "Each launch represents a significant milestone and advancement in terms of how we build, test, and deploy space capabilities in a rapid and responsive manner." The unmanned X-37B, which returned from its last and longest flight in October, is scheduled to launch May 16 from Cape Canaveral Air Force Station, Florida. While an earlier Space Force launch of a GPS III satellite was delayed due to the COVID-19 situation, the X-37B launch has remained on track. Despite being launched by the Space Force, the X-37B remains an Air Force platform. The military has been elusive about what the Boeing-built space plane has been doing on its various missions, beyond noting that it has been used for a number of on orbit experiments. The vehicle has spent a cumulative 2,865 days on orbit, with its last flight being the longest at a record breaking 780 days. In a May 6 press release, the Space Force opened up about some of the experiments that would hitch a ride into orbit aboard the X-37B, most notably one that will deliver solar power to the ground from space via radio frequency microwave energy. That experiment is likely related to the Air Force Research Laboratory's Space Solar Power Incremental Demonstrations and Research (SSPIDR), an effort to collect solar energy with high-efficiency solar cells, convert it to radio frequency, and then beam it to earth. That technology could provide an uninterrupted energy source to expeditionary forces at forward operating bases that have limited access to traditional power sources. “The Space Solar Power Incremental Demonstrations and Research (SSPIDR) Project is a very interesting concept that will enable us to capture solar energy in space and precisely beam it to where it is needed,” Col. Eric Felt, director of AFRL's Space Vehicles Directorate, said in an October statement on the effort. “SSPIDR is part of AFRL's ‘big idea pipeline' to ensure we continue to develop game-changing technologies for our Air Force, DoD, nation, and world.” AFRL has awarded Northrop Grumman a $100 million contract to support space-based experiments supporting SSPIDR. The X-37B will also deploy the FalconSat-8, an educational small satellite developed by the U.S. Air Force Academy that will carry five experimental payloads. Also on board will be two National Aeronautics and Space Administration experiments that will study the effects of radiation and the space environment on seeds used for food products. One reason the vehicle will carry more experiments than prior mission is the attachment of a new service module to the aft of the spacecraft, which will host multiple experiments. “This launch is a prime example of integrated operations between the Air Force, Space Force, and government-industry partnerships,” said Air Force Chief of Staff Gen. David Goldfein. “The X-37B continues to break barriers in advancing reusable space vehicle technologies and is a significant investment in advancing future space capabilities.” https://www.c4isrnet.com/battlefield-tech/space/2020/05/07/here-are-a-few-of-the-experiments-hitching-a-ride-on-the-air-forces-secret-space-plane/

    US to build new nuclear gravity bomb

    Experts say this new higher-yield nuclear bomb appears intended to pave the way for retiring the older B83 megaton bomb.
