No sandbags needed: Marines 3D print a barracks room in 40 hours

By:

The Additive Manufacturing Team at Marine Corps Systems Command and Marines from the I Marine Expeditionary Force operated the world's largest concrete 3D printer at the U.S. Army Engineer Research and Development Center in Champaign, Illinois, according to the Marine Corps.

The combined force effort was used to 3D print a 500-square-foot barracks hut.

“This exercise had never been done before," Additive Manufacturing's project officer Capt. Matthew Friedell said in a news release. "People have printed buildings and large structures, but they haven't done it onsite and all at once. This is the first-in-the-world, onsite continuous concrete print.”

    US Army seeks vendor to disassemble remaining AH-64D attack helos

    by Gareth Jennings The US Army has issued a request for information (RFI) for the ‘depopulation' of its remaining Boeing AH-64D Apache Longbow attack helicopters. Announced by the US Army Program Executive Office – Aviation on 17 August, the Apache AH-64D Attack Helicopter Depopulation RFI seeks to identify potential sources that possess the expertise, capabilities, and experience to meet the requirements necessary to depopulate (disassemble) hundreds of the service's remaining helicopters. “This RFI is to obtain qualified vendors to provide plans, procedures, production information, and reports addressing the depopulation of three to seven AH-64D aircraft per month. Additional work scope includes minor repairs in order to maximise reuse of components for production of the AH-64E [Apache Guardian]. The period of performance for this work is from January 2022 through December 2027 with the first delivery required in June 2023 and the last delivery required in March 2027,” the US Army stated on the beta.sam.gov government procurement website. https://www.janes.com/defence-news/news-detail/us-army-seeks-vendor-to-disassemble-remaining-ah-64d-attack-helos

  • House panel advances $733B defense budget bill over GOP objections

    House panel advances $733B defense budget bill over GOP objections

    By: Leo Shane III and Joe Gould WASHINGTON ― House lawmakers advanced a $733 billion defense policy bill on Thursday after nearly 21 hours of sometimes heated debate on the size of the Pentagon budget, the size of the country's nuclear arsenal and a host of other military priorities for next year. The 33-24 final vote by the House Armed Services Committee on the draft of the defense authorization bill marked one of the most divided stances from the committee in years, as Republicans voiced concerns with Democrats' priorities in the measure. The legislation, which sets military spending policy for the upcoming fiscal year, has been adopted by Congress for 58 consecutive years, usually by sizable bipartisan margins. Committee officials insist that's because the needs of the military usually rise above the partisan politics of Capitol Hill. But this year, the narrow passage out of committee illustrated the stark divide in defense policy between the two parties, and hints at a lengthy battle to come as the measure moves across Capitol Hill to the Republican-controlled Senate in the coming weeks. Committee Chairman Adam Smith, D-Wash., in recent days said he is committed to finding a palatable bill for both Republicans and Democrats. But during the marathon debate he repeatedly defended his party's plans for $733 billion in defense spending for fiscal 2020 as a responsible and sufficient mark. “By a reasonably comfortable margin, this is the largest budget we will have ever passed in Congress (for defense) and it's a significant improvement on where we were before,” he said before the committee vote. Smith had already set aside some of his own priorities in a bid to win support from the panel's hawkish Republicans, who are likely to influence their caucus when it comes time to vote the bill out of the House. Without that support, Democrats may struggle to gather enough votes from progressives in their own caucus, who have questioned even the lower level of spending. But Senate Republicans have already set their authorization bill draft at $750 billion, a mark recommended by the White House and defended by HASC ranking member Mac Thornberry, R-Texas. He said that the figure is needed to keep pace with military modernization and readiness needs. Thornberry's amendment included a lengthy laundry list of weapons and platforms left out of the bill. “I worry that we talk about this like it's just numbers we're pulling out of the air,” he said. “These are real things. An aircraft carrier gets delayed a year if $733 billion is the way it comes out.” The bill includes a 3.1 percent pay raise for troops next January — a point of agreement on both sides that Smith repeatedly referenced — and provisions for increased protections for sexual assault victims, increased oversight of military housing problems and parameters for a new Space Corps within the Air Force. But fights over the effects of climate change on national security, limitations on the use of the Guantanamo Bay detention camp and a provision mandating gender integration in Marine Corps basic training further divided the committee. On a series of Republican amendments aimed at preserving funds for the nuclear arsenal — including one to protect deployment of low-yield nuclear weapons on submarines — Democrats repeatedly defeated Republican proposals. Similarly, the committee upheld several provisions designed to put a check on President Donald Trump's ability to shift resources from the Defense Department to the U.S. southern border with Mexico. Democrats have accused Trump of abusing his emergency powers to shift Department of Defense funds for the border and send thousands of troops there. In the committee debate, Republicans generally argued Trump is taking necessary and normal steps to secure the border given political resistance to addressing the issue. “I want everybody to understand we have been sending DoD assets to the border since the Alamo,” said Rep. Mike Rogers, who sponsored one of the amendments. “We have to do it in order to keep our border secure and deal with the humanitarian crisis.” The measure now shifts to the full House, where Smith and Democratic leadership will have to build a coalition of supporters to get the measure to negotiations with the Senate. That chamber will vote on its draft next week. Work on a compromise draft between the House and Senate is expected to last through most of the summer and fall. https://www.defensenews.com/congress/2019/06/13/house-panel-advances-733b-defense-budget-bill-over-gop-objections/

  • Getting Brexit Done Brings Defense Challenges

    Getting Brexit Done Brings Defense Challenges

    Tony Osborne Boris Johnson's election landslide on Dec. 12 makes Brexit on Jan. 31 a certainty. But as the chants of “Get Brexit Done”—a slogan used by the Conservative party in their election messaging—fade away, Britain's place in the world appears infinitely more vulnerable. Johnson's parliamentary majority means he can now sweep aside any opposition to pursue his vision of Brexit. But he was not the only victor. The Scottish National Party secured 48 of Scotland's 59 seats, which the party says is a mandate for a second independence vote. If it were to succeed, there would be far-reaching consequences to Britain's national defense capability. Scotland is home to strategically important air bases and, most significantly, the UK's Trident-based nuclear deterrent. Johnson is unlikely to approve such a referendum at least in the short-term, but the Scottish nationalists could make life difficult for his government, and preventing a referendum could be seen as undemocratic. The complexities of having Northern Ireland as the only part of the UK to share a land border with an EU country, the Republic of Ireland, mean that after a Brexit there will be a border in the Irish Sea between Northern Ireland and the rest of the UK. This, too, could have security implications and lead to renewed violence from unionist groups, as they see their political influence being eroded. Nationalists see an opportunity for a united Ireland once again. There is also uncertainty about the futures of Gibraltar and Diego Garcia. Exiting the EU means British security forces no longer will be linked to EU databases on criminals, organized crime and terror. Questions also have arisen about Russia's influence in the British democratic process, with Johnson suppressing publication of an intelligence report on Russian infiltration in British politics during the election run-up. And there is a fiscal aspect as well. Since the Brexit vote in 2016, Britain's GDP has begun to stagnate as economic output and investments fall away. National debt also is rising. The British Parliament's own analysis suggests GDP could be 7% lower over the next 15 years than without Brexit, and even with a free-trade agreement established with Europe. Questions then would arise about whether Britain could afford to maintain military spending. Currency fluctuations will affect big-budget programs such as the ongoing purchase of the Lockheed Martin F-35 Joint Strike Fighter (JSF). Britain is one of a handful of NATO countries with defense spending at or above NATO's target of 2% of GDP. The Conservative manifesto published in the run-up to the election calls for this to increase by at least 0.5% above inflation every year. Britain's defense budget for 2019-20 was £39.5 billion ($52.7 billion), and this will rise to £41.3 billion for 2020-21. The government will maintain and renew the Trident nuclear deterrent but also support the defense industry with “ambitious global programs,” including local construction of Type 31 frigates and local production of the Boxer armored vehicle. In December, the Royal Navy commissioned the second new Queen Elizabeth-class aircraft carrier, HMS Prince of Wales, in a further step toward restoring the country's carrier capability. Following operational trials in the fall off the Eastern U.S., more are planned around the UK during 2020, paving the way for the first operational deployment in May 2021. The UK plans to have 35 F-35s in service by the end of 2022, and the government has committed to buying all of the 138 F-35s it planned to purchase when it joined the JSF program in the early 2000s. Whether that commitment is met and if the UK will purchase additional variants could be determined in a strategic defense and security review planned for 2020. With the retirement of the Panavia Tornado last March, the Eurofighter Typhoon fleet has become the heavy-lifter of the UK's air defense mission and is continuing air strikes against Islamic State group sites in Iraq and Syria along with the UK's MQ-9 Reaper unmanned aircraft systems. The UK now is stepping up development of a Typhoon replacement for the mid-2030s with the Tempest future combat air system, supported by Italy and Sweden. More nations could join in 2020, with Japan a key target. And with delivery of the first of nine Boeing P-8 maritime patrollers, the UK is back in the long-range antisubmarine-warfare business, with an initial operating capability expected in April. https://aviationweek.com/defense-space/getting-brexit-done-brings-defense-challenges
