US Army ponders ‘radio as a service’ to keep communications up to date

“It is ironic to me that we would actually come up with any IT program where we think we’re going to be fielding the same capability for decades.”

    Britain moves to boost Ukraine’s naval chops

    By: Andrew Chuter LONDON — Britain is stepping up its military support in Ukraine with an announcement that the U.K. will lead a multinational maritime initiative to train the Ukrainian navy. During a visit to Ukraine on Aug. 17 British Defense Secretary Ben Wallace confirmed the Royal Navy is coordinating a training initiative which also involves Canada, Denmark and Sweden. The training initiative will be complemented by U.S. security assistance support, said the British Ministry of Defence in a statement. Other nations are expected to join the naval training effort, said the MoD. The British-led training will focus on areas such as navigation, operational planning, military diving, sea surveillance, firefighting and damage control. The Royal Navy also plans to deploy warships to the region later in the year, Wallace said. Last year the Royal Navy Type 45 destroyer HMS Duncan visited Ukraine as part of the NATO's Sea Breeze exercise. That followed a visit by the survey ship HMS Echo. The U.K. has been conducting maritime training with the Ukraine for a while. Last year the British announced they were enlarging the scope of a wider military training effort, known as Operation Orbital, by deploying training teams from the Royal Navy and Royal Marines to boost a Ukrainian Navy facing increasing threats from Russia in the Sea of Azov. The Ukrainians are trying to rebuild a maritime presence following Moscow's annexation of Crimea in 2014. Ukraine lost most of its navy, including 75 percent of personnel, 70 percent of ships and key infrastructure. It faces a rising number of threats from the Russians in the Sea of Azov and the Black Sea, and its armed forces continue to counter Moscow-backed separatists in the Donbass region of the country. Last year the Ukrainian navy unveiled a 15-year, three-stage strategy to rebuild naval capabilities starting with the aim of developing capabilities to establish control over territorial waters and beyond by 2025. Britain announced late last year it was extending Operation Orbital by three years to March 2023, and despite a COVID-19 enforced suspension, now lifted, the U.K. armed forces have trained over 18,000 Ukrainian military personnel. https://www.defensenews.com/global/europe/2020/08/19/britain-moves-to-boost-ukraines-naval-chops/

  • Marine Corps to Increase JLTV Buy to 15,000 to Replace its Humvee Fleet

    Marine Corps to Increase JLTV Buy to 15,000 to Replace its Humvee Fleet

    The Marine Corps is nearly doubling the number of Joint Light Tactical Vehiclesit plans to buy to replace its fleet of aging Humvees, officials said this week. The planned increase -- up to about 15,000 from the 9,000 the service initially planned to buy -- comes as the Marine Corps recently declared the JLTV has reached initial operating capability and is ready to deploy with Marines into combat. The JLTV is the result of a joint effort by the Army and the Marine Corps to field a more capable tactical vehicle after seeing how the Cold War-era Humvee could not protect troops from the powerful, homemade bombs enemy forces used on the battlefields of Iraq and Afghanistan. The Corps had originally planned on buying just 5,500 JLTVs but later increased that number to 9,000. Even with that increase, the Marines maintained earlier this year that the JLTV would replace only about 60 percent of the service's Humvees over the next decade. https://www.military.com/daily-news/2019/08/15/marine-corps-increase-jltv-buy-15000-replace-its-humvee-fleet.html

    Watch the skies in 2022 for the first B-21 bomber flight

    By: Valerie Insinna WASHINGTON — Sorry, aviation geeks: The first flight of the U.S. Air Force's latest stealth bomber won't be happening this year. The Air Force had once projected the first flight of the Northrop Grumman B-21 Raider would occur in December 2021, but the new bomber will not be ready to roll out until early next year for a flight in mid-2022, said the Air Force Rapid Capabilities Office director, Randall Walden, according to a Jan. 15 story in Air Force Magazine. The RCO manages the B-21 program on behalf of the service. Two B-21s are under construction at Northrop Grumman's production facility in Palmdale, California. The first aircraft hasn't made it to final assembly yet but is “really starting to look like a bomber,” Walden told Air Force Magazine. “The second one is really more about structures, and the overall structural capability,” Walden said. “We'll go in and bend it, we'll test it to its limits, make sure that the design and the manufacturing and the production line make sense.” Although information about the B-21 is notoriously limited, with many details of the Raider's cost, appearance and capability classified, Walden offered a couple optimistic notes about the program's progress. For one, production of the B-21 is already becoming more efficient during the build of the second aircraft, he said. Northrop Grumman is using a business jet as a test bed for new avionics and software, allowing those systems to be debugged before they are installed in the B-21 aircraft. While there have been some disruptions to the supply chain due to the COVID-19 pandemic, Walden said the program has worked with companies to mitigate changes to the production schedule. “In the last few months, we did another successful end-to-end demonstration to further mature that hardware and software, and it's working quite well,” Walden said. “We're preparing ourselves not just for first flight, but ultimately the subsystem testing that will be required during those flight test phases.” The Air Force has committed to buying at least 100 B-21s, although officials such as Gen. Timothy Ray, who leads Air Force Global Strike Command, said more will be needed to meet the service's future bomber requirements, which could be in excess of 220 aircraft. The service is expected to make a final decision this year on which bomber installations will first host the Raider. In March 2019, the Air Force picked Ellsworth Air Force Base in South Dakota as its preferred location, with Dyess AFB in Texas as an alternate location. A virtual industry day was held Jan. 11 to provide information on contract opportunities for construction projects needed to support B-21 operations. Those facilities could include a “low-observable restoration facility, a wash rack and general maintenance hangar, and a mission operations planning facility,” according to the Air Force. The service expects to begin fielding the B-21 in the mid-2020s. https://www.defensenews.com/air/2021/01/19/watch-the-skies-in-2022-for-the-first-b-21-bomber-flight/
