Boeing proposes designs for new ICBM deterrent

By Stephen Carlson

July 24 (UPI) -- Boeing has proposed design options to the U.S. Air Force for design of the Ground Based Strategic Deterrent, a possible replacement for the Minuteman III intercontinental ballistic missile.

"We offered the Air Force cost and performance trades for a deterrent that will address emerging and future threats," Frank McCall, vice president for Boeing Strategic Deterrence Systems, said in a press release.

"By considering the various capabilities and opportunities for cost savings, the Air Force can prioritize system requirements as we progress toward the program's next phase," McCall said.

Boeing received a $349 million contract from the Air Force last August for work on the GBSD, and completed a design review in November.

A system functional review will be completed later this year, while Boeing is expected to present the completed design to the Air Force in 2020.

Along with Boeing, Northrop Grumman and Lockheed Martin are competing for development contracts on the new missile.

The Ground Based Strategic Deterrence program is the U.S. Air Force effort to replace the venerable LGM Minuteman II ICBM, which is nearing the end of its lifespan.

Upgrades of the Minuteman series of ICBMs have been in service since the early 1960's. Much of its components are over 50 years old and making replacement necessary.

The GDSM program is still in its early stages but is expected to start entering service in 2027 and is planned to be in service until 2075.

The current Minuteman III is an underground silo-launched missile armed with nuclear warheads with up to a 350 kiloton yield. It has a range of well over 6,000 miles, though the exact maximum range classified.

The Minuteman III can carry up to three multiple independent reentry vehicle warheads but is restricted to one per missile by treaty. The United States currently has 450 ICBMs in service.

    Defense Agency Wants To Acquire UAS Services For Use In Disaster Relief

    By Calvin Biesecker The Defense Department's agency charged with providing logistics support to warfighters is seeking information from vendors capable of providing unmanned aircraft systems (UAS) that can deliver food and water to people in remote areas following a disaster. The Defense Logistics Agency (DLA) in an information request lists key capabilities and requirements for its UAS needs as part of a forthcoming acquisition for the services in the East and Gulf Coasts of the U.S. “This is in support of Defense Logistics Agency Troop Support's Subsistence Contingency Operations and Natural Disaster relief efforts,” the DLA says in a Jan. 10 Request for Information on the government's FedBizOpps site. In addition to supporting warfighters with their supply needs, DLA also provides support to the Department of Homeland Security's Federal Emergency Management Agency (FEMA), which supports disaster response to U.S. states and territories. Support for FEMA is “becoming more routine,” a DLA spokesman told Defense Daily on Thursday. The DLA announcement doesn't specify a specific event or series of disasters that is driving the need for remote delivery of food and water by UAS but it does follow a series of dramatic storms and wildfires over the past 16 months. In particular, Hurricane Maria, which hit the U.S. Virgin Islands on Sept. 19, 2017, and Puerto Rico the day after. Maria impacted 100 percent of the populations of Puerto Rico and the U.S. Virgin Islands. The Caribbean islands of Puerto Rico and the U.S. Virgin Islands are both U.S. territories located a 1,000 or more miles from Florida. The devastation in Puerto Rico made deliveries of relief supplies difficult. “Hurricane Maria severely damaged or destroyed a significant portion of both territories' already fragile critical infrastructure,” FEMA said in a July 12, 2018 after-action report on the 2017 hurricane season. “Maria left Puerto Rico's 3.7 million residents without electricity. The resulting emergency response represents the longest sustained air mission of food and water delivery in Federal Emergency Management Agency history.” Rather than acquire the systems outright, DLA wants a contactor that can provide the delivery services through a “turnkey deployment” based on a performance-based concept of operations developed as part of a research effort. Capabilities must be in place within one to two days of an event, the agency says. It also says the drones must be non-developmental and be able to operate beyond visual line of sight in austere conditions. Payloads on the UAS will weigh between 250 and 500 pounds and “typically” consist of cases of bottled water, Meals-Ready-to Eat, and other related operational items that will be released remotely without damage to the supplies. For the deployments, the drones must be able to operate from maritime vessels to land, land to sea vessel, and land to land. DLA says that sea-based operations “will be coordinated with the U.S. Coast Guard.” In the late summer of 2017, before Maria hit, Texas was hit by Hurricane Harvey, which was followed by Hurricane Irma, which slammed into Florida, Puerto Rico and the U.S. Virgin Islands. Harvey affected 30 percent of the population in Texas and Irma affected 85 percent of the combined populations of Florida, Puerto Rico and the U.S. Virgin Islands. Around the same time the three storms hit the U.S. and its territories, another hurricane interfered with maritime operations in the Caribbean Sea and FEMA also supported California's response to “some of the most devastating wildfires to ever impact the state,” the after-action report said. The DLA wants responses to its Request for Information by Jan. 25. The agency said the timing of the release of the Request for Proposals is unknown as is the ultimate amount of the eventual procurement pending the completion of market research. https://www.rotorandwing.com/2019/01/18/defense-agency-wants-acquire-uas-services-use-disaster-relief/

    UK hits pause on defense review due to coronavirus

    By: Andrew Chuter LONDON — The British government has hit the pause button on its integrated defense review as it pours its efforts into battling the coronavirus crisis, Cabinet Office officials have told the parliamentary Defence Committee. “The Cabinet Office has informed the defence select committee that work on the integrated review has been formally paused across Whitehall,” the committee announced April 15. Committee chair Tobias Ellwood said in a statement that the move by the Cabinet Office, the department leading the review, was the right move to take given the crisis. “There would be no point in conducting an in-depth review of the nation's defence and security challenges to an artificial deadline, especially at a time when Whitehall is rightly focusing on tackling conronavirus,” Ellwood said. The recently appointed Defence Committee chair said that when the review restarts it will have to do so “with the added consequences of the pandemic to be considered.” A spokesperson for the Defence Committee said the Cabinet Office had not given any indication as to when it might start to ramp up the review effort again. However, two sources tell Defense News that the review could go on ice for up to a year. In a letter announcing the pause, deputy national security adviser Alex Ellis said that while the review was on hold, the government would be retaining a “small core capacity to think about the long-term effects of COVID-19 and issues expected to be covered in the Integrated Review." This team will be very limited in size and function, he added. The Ministry of Defence already faced mounting budget problems before the pandemic struck. Now, the massive economic crisis facing the British government makes it highly unlikely any additional cash will be found for defense, despite the prominent role the military is playing here combating the virus. The review was initiated immediately following Boris Johnson's election as prime minister in early December. Johnson promised it would be the most fundamental review of its kind since the end of the Cold War. Defense, security, foreign policy and international development strategy were to all be part of the effort. The review was scheduled by the government to be completed by July, a timescale the Defence Committee, analysts, lawmakers and others all said was too quick. Johnson first signaled his intention to slow down work on the review in a letter to Ellwood and two other committee chair dated March 24. “We have diverted resources from across Government and the Civil Service to work on COVID-19, scaling back efforts on the Integrated Review,” Johnson said at the time. Quizzed last month by parliamentarians about a possible delay to the review, Defence Secretary Ben Wallace said the government was open-minded about putting the work on hold. “There is no ideological block or determination to carry on come what may," Wallace said then. “With this coronavirus growing, if it is the right thing to do, we will absolutely pause the review if necessary; if not, we shall move forward.” Jon Louth, an independent defense analyst, believes the government may have to start the review process over again, given the changing circumstances. “I think we are close to going back to square one, if the budget settlement for defense is to be unpicked and secured as part of a late Autumn or Spring [2021] government-wide spending review,” he said. “Who could have any confidence in what the defense equipment program funding settlement would actually be? It could involve unpacking current contracts, but also unpick some of the ambition we have in terms of new things. “What we have and what we would like are going to be colored by a budget settlement smaller than people were anticipating; in fact, quite substantially smaller. Whether that means the MoD starts to think about reprofiling things to the right or really starts taking strategic choices, we will have to wait and see,” added Louth, who until recently was a senior analyst at the Royal United Services Institute think tank in London. https://www.defensenews.com/global/europe/2020/04/15/uk-hits-pause-on-defense-review-due-to-coronavirus/
