BAE Offers Truck-Mounted Howitzer For Army Stryker Units
Already fielded in Sweden — and mounted on a Volvo truck — BAE's 155 mm Archer will compete in a US Army “shoot off” early next year.
WASHINGTON: The Army is seeking a self-propelled replacement for its venerable towed artillery pieces. The old ones can't keep up with mechanized Stryker units and lack armor protection. BAE Systems says its Archer armored howitzer is the quickest cannon on the draw — a life-or-death factor in fast-moving future combats.
The US is experimenting intensely in how to speed the process from detecting a potential target to sending accurate target coordinates to a specific gun. Once Archer receives such target coordinates, it can come to a stop and open fire within 20 seconds, said Henrik Knape, a BAE exec based in Sweden, where the gun is already in service. Within two minutes from that first shot, Knape went on, the truck-mounted 155mm howitzer can fire another five to seven rounds, get back underway, and put 500 meters (a third of a mile) between itself and the location it fired from.
That's a long enough distance in a short enough time that retaliatory fire from the enemy's artillery is probably going to miss. Even for an advanced adversary (pronounce that “Russia”), which uses specialized counter-battery radars to track the trajectory of incoming rounds and calculate the precise position of the unit firing them, it will take multiple minutes to bring its own guns or drones to bear.
In US operations, the time from detecting a target to firing on it is typically “tens of minutes.” Experimental artificial-intelligence systems can cut that to tens of seconds, but those are years from being battle ready.
Archer has other advantages as well, Knape and his US-based colleague Chris King told a small group of reporters:
- It's been in Swedish service since 2016, with the Defense Ministry asking Parliament to fund another 24 guns, so it's already extensively field-tested.
- It's armored against shrapnel and small arms, in case the enemy does get close.
- Its long barrel – 52 calibers, a third longer than the standard US howitzer – gives it extended range, comparable to the tracked ERCA howitzer entering service with US armored units in 2023. That gun is already qualified in US testing to fire precision-guided projectiles like Raytheon's Excalibur and BAE's own BONUS.
- And it's mounted on a six-wheel-drive, articulated Volvo chassis with enough cross-country mobility to keep up with the Army's 8×8 Strykers, which currently have only towed guns to accompany them.There are smaller wheeled artillery vehicles on the market than Archer, which doesn't fit on the standard C-130 turboprop transport, Knape and King acknowledged. (We check out a Humvee-mounted 105 mm cannon here).But none of them, they argue, has Archer's combination of firepower, protection, and quickness.
- The secret to that speed is automation, BAE says. While the US Army's current systems – both towed howitzers and the armored M109 Paladin – still rely largely on human muscle to manhandle heavy shells into the gun, Archer has a built-in autoloader. While well-trained human crews can actually fire faster than autoloaders for brief periods, the mechanical systems don't get tired or injured, and they allow for a much smaller gun crew. Archer can theoretically operate with a single soldier aboard, although it's designed for a crew of three – all of whom can stay inside the armored cabin while the weapon fires and reloads.https://breakingdefense.com/2020/10/bae-offers-truck-mounted-howitzer-for-army-stryker-units/

US Navy eyes new design for next-generation destroyer
David B. Larter WASHINGTON — The U.S. Navy is looking to build a new generation of destroyers from a clean-sheet design, following the model of one of its most successful ship classes, the Arleigh Burke-class DDG, the service's top officer said Tuesday. The idea, colloquially referred to in-house as DDG Next, is to build a new hull smaller than the nearly 16,000-ton Zumwalt-class destroyer but still big enough to accommodate a larger missile magazine, Adm. Michael Gilday told a virtual audience at Defense One's State of the Navy event. “I don't want to build a monstrosity. But I need deeper magazines on ships than I have right now,” the chief of naval operations said. “I'm limited with respect to DDG Flight IIIs in terms of what additional stuff we could put on those ships. ... So the idea is to come up with the next destroyer, and that would be a new hull. The idea would be to put existing technologies on that hull and update and modernize those capabilities over time.” The Navy is supposed to start buying the new ship in 2025, according to the service's 2020 30-year shipbuilding plan, though it's unclear how its forthcoming force structure assessment will affect those plans. In his recent speech on the Defense Department's plan for a 500-plus ship Navy, Defense Secretary Mark Esper made no mention of the future large surface combatant. To avoid another costly failure, such as the canceled next-generation cruiser or severely truncated DDG-1000 program, the service is harkening back to its successful Arleigh Burke program, the mainstay of the Navy's surface combatant program for the past 30 years, Gilday said. Much like on the forthcoming Constellation-class frigates, the service plans to install fielded systems on the new ship and upgrade them over time. “So think DDG-51 (that's exactly what we did): We had a new hull but we put Aegis on it,” Gilday said. “We put known systems that were reliable and were already fielded out in the fleet. That's kind of the idea. I call it DDG Next to kind of right-size it. Smaller than a Zumwalt but packing some heat nonetheless.” The Navy estimates it would need $22 billion annually in constant year 2019 dollars to execute its old shipbuilding plan, though the Congressional Budget Office put the estimate more than 30 percent higher. A major driver in the difference between the CBO and Navy estimate was the cost of a future large surface combatant, according the Congressional Research Service. The emergence of hypersonic missiles has been a driving factor in the Navy's desire to field a new large surface combatant since such weapons wont fit in the current vertical launch system cells on Burke-class destroyers and existing cruisers. They will, however, fit in the Virginia Payload Module being built into the Block V Virginia submarines awarded last year. https://www.defensenews.com/naval/2020/10/13/the-us-navy-is-eyeing-a-next-generation-destroyer-from-a-new-design/

Royal Australian Air Force benefits from Airbus SmartForce digital services
Amberley (Australia), January 28, 2021 – Airbus has recently signed a contract to provide a digital services focus for the maintenance of the Air Refueling Boom System (ARBS) on the Royal Australian Air Force (RAAF) KC-30A Multi-Role Tanker Transport (A330 MRTT) fleet. Based on the Airbus suite of digital services SmartForce, this service is intended to support the operator in reducing maintenance costs and improving fleet availability by optimizing the fault diagnosis and troubleshooting tasks for the ARBS of the tanker aircraft, based on data analytics applications. The Central Data System plays a key role, allowing operators to draw on the flight data recorded by the Mission Recording System and provides information outputs about issues registered during the flight and recommended maintenance actions to fix them. Within the KC-30A Enterprise, the Central Data System is a joint development built upon a successful long-standing collaboration among Airbus, the Commonwealth of Australia (CoA) and the Australian KC-30A Through Life Support (TLS) provider Northrop Grumman Australia, in sharing data and defining the architecture of the system. Future proposed development of the capability will allow customers which apply this technology to their fleet to be able to extend the ARBS analytics to entire aircraft level diagnostics. Stephan Miegel, Head of Military Aircraft Services at Airbus Defence and Space, said:“Since the launch of SmartForce in 2018, Airbus is fully committed to support the digital initiatives of our customers. Working collaboratively with them, we have signed five agreements for the co-development of new services and technologies. We are proud to see that military operators are increasingly joining us on our digital journey.” Jake Adams, Northrop Grumman Australia KC-30A Program Manager, said: “The introduction of the Central Data System has provided significant benefits in terms of increased availability of the ARBS. The recent agreement between Airbus and Northrop Grumman Australia ensures that the RAAF continues to benefit from this capability as well as providing the opportunity for ongoing collaboration and sharing of data and analytics to enhance the ARBS capability.” Group Captain Scott Parry, Officer Commanding Heavy Air Lift Systems Program Office, commented: “The Central Data System delivers a significant capability benefit for the KC-30A aircraft and demonstrates the strong commitment within the KC-30A enterprise to innovation and improvement.” SmartForce is a suite of services enabling military operators to exploit aircraft data to improve troubleshooting, optimize maintenance effort, predict maintenance actions and plan smartly for material demand and improving the fleet availability. SmartForce capitalizes on the new power of big data analytics coupled to secured connectivity to maximize mission readiness. @AirbusDefence @AusAirForce #A330MRTT Your Contact Pablo Correa External Communications - Airbus Defence +34 6 89 66 96 02 Send an email Belinda Ng Communications - Airbus Asia-Pacific +65 9683 6361 Send an email View source version on Airbus: https://www.airbus.com/newsroom/press-releases/en/2021/01/royal-australian-air-force-benefits-from-airbus-smartforce-digital-services.html
