  Construction of first permanent US F-35 campus in Europe begins at Lakenheath

  By CHRISTOPHER DENNIS RAF LAKENHEATH, England — A $205 million construction project to prepare RAF Lakenheath for the arrival of two squadrons of U.S. Air Force F-35A Lightning II fighter jets in 2021 officially got underway Monday. The commander of U.S. Air Forces in Europe - U.S. Air Forces Africa, Gen. Jeffrey Harrigian, and other dignitaries plunged shovels into dirt at what will become the first permanent site for U.S. F-35s in Europe. U.K. firms Kier and VolkerFitzpatrick will build a flight simulator facility, maintenance unit, hangars and storage units at the site, in time for the arrival of 48 F-35s in November 2021. The Royal Air Force currently has nine F-35s at RAF Marham, about 25 miles north of Lakenheath. “This will be a great opportunity to reinforce together how we will train, execute and operate on a daily basis, and allow us to deepen what is a critically important relationship,” Harrigian said at the groundbreaking. The project is the first in a broad program to support Air Force operations in the U.K. A further $1 billion is expected to be invested in the program over the next seven to 10 years, said the Defense Infrastructure Organization, which last year awarded the contract for the F-35 campus. “The project team is in good shape — we are on schedule for completion in 2021,” Kier's managing director of aviation and defense James Hindes was quoted as saying by The Construction Index, an industry website. The completed campus will host around 1,200 U.S. airmen. Currently, more than 9,100 U.S. servicemembers are based in the U.K, according to Pentagon data. Recent problems with engine delivery of the F-35A are not expected to delay the arrival of America's newest fighter jet at Lakenheath, a 48th Fighter Wing spokeswoman said Monday. Of the 81 engines that were delivered in 2018, 86% were late, according to a Government Accountability Office report in April. That was up from 48% that were not delivered on time the previous year, when fewer engines were delivered. The delays were due in part to an increase in the “average number of quality issues per engine”— 941 in 2018 against 777 a year earlier, the GAO report said. United Technologies' Pratt and Whitney unit, the only company to make the engines, is under a corrective action request from the Defense Contract Management Agency for “poor delivery performance,” according to a July report by Bloomberg News. https://www.stripes.com/news/construction-of-first-permanent-us-f-35-campus-in-europe-begins-at-lakenheath-1.590422

  U.S. Army Flickr Page Inadvertently Reveals New Hypersonic Weapon Concept

  Steve Trimble A new hypersonic weapon concept has emerged inadvertently on a social media page managed by U.S. Army Secretary Ryan McCarthy that describes a Mach 5-plus projectile with the ability to penetrate into defended airspace and dispense a multi-role loitering air system over a target area. The concept—labeled as the Vintage Racer Loitering Weapon System—reveals a solution to an operational problem for the Army: When high-speed munitions, such as the Long-Range Hypersonic Weapon (LRHW), enter service with the ability to strike targets thousands of kilometers away, how will the Army find the most elusive targets, such as road-mobile launchers for intercontinental ballistic missiles (ICBM) or radars for air defense batteries? The Vintage Racer concept, as revealed so far, suggests it may be possible to launch a hypersonic projectile into a general area without knowing the specific location of the target. As it reaches the target area, the projectile may be able to dispense a loitering air system, which is then uses its own sensors to find and identify the target. If the loitering system also carries a warhead, it may be able to strike the target by itself or transmit the target coordinates to another weapon. Once the existence of the Vintage Racer concept appeared, a Russian expert on military-political affairs noted such an idea has been discussed as a possibility within the hypersonic weapon community. “The fear is that [this] hypersonic ‘something' might reach the patrol area of road-mobile ICBM launchers [after] penetrating any possible air and missile defense, and then dispense loitering submunitions that will find launchers in the forests,” said Dmitry Stefanovitch, an expert at the Moscow-based Russian International Affairs Council. Only the broadest information about the Vintage Racer weapon is visible on the briefing paper describing the concept. The image appears in an album of photos from the Association of the U.S. Army convention posted to McCarthy's Flickr account last October. Most of the pictures from the event show McCarthy meeting attendees, giving speeches and receiving informal, standing pitches from industry officials in the exhibit hall. One picture shows McCarthy standing at a table across from an unidentified industry official in the exhibit hall. The table is covered with multiple objects, including a General Atomics press release, what appears to be a model of the LRHW and a rifled barrel of a 155mm artillery gun with a hole burned through the object. The table also is covered with at least four sheets of briefing papers, of which three are not visible. The only visible paper, which is partly obscured by McCarthy's right hand, is headlined “Vintage Racer - Loitering Weapon System (LWS) Overview.” The paper includes six main bullet points, which read “Hypersonic Ingress,” “Survivable,” “Time Over Target,” “Multi-role,” “Modular payload,” and “Cost Imposition Strategy.” Ten sub-bullets are also visible on the page, but the letters are not readable. At the bottom of the page, a tag line highlighted in yellow is partly obscured by McCarthy's hand, but the visible portion reads: “Long Range, Rapid Ingress.” A vague reference to Vintage Racer previously appeared in Defense Department budget justification documents released in February, but went unnoticed. Under a line item owned by the Office of Secretary of Defense for a “quick reaction fund,” Vintage Racer is described as a “recent success story.” “The project successfully validated aerodynamic design with wind tunnel testing and integrated a guidance subsystem for targeted kinetic effects before culminating in a fiscal 2019 flight test. Documentation and prototype technologies transitioned to the U.S. Army for additional development and follow-on acquisition activities,” according to budget documents. https://aviationweek.com/defense-space/sensors-electronic-warfare/us-army-flickr-page-inadvertently-reveals-new-hypersonic
