  UK facilities for American F-35 jets are delayed and over budget

  By: Valerie Insinna WASHINGTON — The U.S. Air Force is on track to begin permanently basing its F-35 jets abroad next year, with RAF Lakenheath in England set to become the service's first international F-35 base. But construction on new hangars and facilities necessary for supporting the high-tech stealth jet have gone over budget and over schedule, and many buildings won't be ready when the first planes arrive in November 2021. On average, construction projects associated with the F-35 beddown at Lakenheath are about 25 percent over the initial $480 million budget estimated in 2015, said Lt. Col. Clinton Warner, who leads the 48th Fighter Wing's F-35 program integration office. “The overall trend has been projects are late and also over budget,” he told Defense News during a July interview. “A lot of the assumptions that were made back in 2015 weren't necessarily valid. There's been cost growth that was outside of the planning assumptions that were made back in 2015.” The cost increase is not the only problem. As RAF Lakenheath's first F-35 squadron stands up, neither the hangars planned to house the jets nor the headquarters building used for planning operations and maintenance will be ready, Warner said. A training simulator building will also be late. Despite the delays, the Air Force still plans to move forward with the beddown of the jet. Warner said the service is exploring options to keep operations on track, such having the new F-35 squadron share space with existing units — which include three American F-15 squadrons — or potentially leasing additional facilities on base from the United Kingdom. “In terms of getting here and flying the aircraft, we will still do that. [There is] really no difference in terms of the capability is going to be delivered, but it'll just look different in how we do it,” Warner said. “It will be some strain on the units here at the base, as there's more crowding and with waiting for those facilities to come online.” The arrival of U.S. Air Force F-35s in Europe has been a long-awaited milestone for the service, which announced in 2015 that RAF Lakenheath would become the first international location to get the jets. Since then, F-35s temporarily deployed to the base in 2017. “Having a fighter with the capability of the F-35s one hop closer to a part of the world that's seemingly less stable certainly will have a deterrent effect,” said Frank Gorenc, a retired four-star general who commanded U.S. Air Forces in Europe from 2013 to 2016. “Being able to daily train with the partners that have F-35s will have a deterrent effect,” Gorenc told Defense News. “It will cause interoperability to soar both on the maintenance side and on the operations side. I think the benefits of having that equipment — the demonstration of having a fifth-generation [fighter jet] in theater combined with F-15Es and F-16s — I think is the right signal.” Under the current plans, F-35 pilots and maintainers will begin to arrive at RAF Lakenheath in June 2021, with the first aircraft to follow in November. The base will eventually be home to two F-35 squadrons, each with a total of 24 jets. That beddown will follow more than five years of planning and development on the part of the Air Force, which stood up a team in 2015 to get the base ready for the incoming jets. In 2018, the U.S. Air Force chose Kier-Volker Fitzpatrick, a joint venture of U.K.-based design and construction firms Kier Group and VolkerFitzpatrick, to build and renovate all installations associated with the F-35 presence at RAF Lakenheath. Construction began in July 2019, with seven of 14 new facilities — which will include new hangars, a building for flight simulation, a maintenance unit and storage facilities — currently either being built or already complete. As unforeseen costs have mounted, the base's program integration office has had to request $90 million in additional funding from Congress, as well as permission from the Pentagon to revise the scope of the projects, Warner said. But there's no overarching answer for why costs have ballooned. “Each individual project had a different set of assumptions, a different set of risk profiles, and some were correct and some are not correct,” Warner said. With only a few years between the decision to base F-35s at Lakenheath in 2015 and the original planned start of operations in 2020, the U.S. government wanted to put a construction firm under contract sooner rather than later, said Stephen King of the Defence Infrastructure Organisation, a U.K. government agency charged with overseeing the building and maintenance of military facilities. But workforce costs grew as the project was discovered to be more complex than originally anticipated. “When the workers are tendered, the prices that are coming back in are found to be different from those originally estimated, and it seems to be the price of doing business on a military establishment. There seems to be an ‘add-on' to the outside market,” King said. Because the F-35 is a stealth jet that processes large amounts of classified information, many of the installations linked with its operations must meet certain security specifications. Building those structures to both U.S. and U.K. standards while using a foreign workforce of U.K. citizens posed challenges that the U.S. Air Force did not foresee during the design process, Warner said. “Luckily most of these problems are behind us, but they did cause delays in terms of when we were programming out in the schedule and looking at what we thought it would look like,” he said. “Some of the challenges associated with building those secure facilities were not fully understood.” Air Force officials have said keeping the projects on track was always going to be a challenge. In 2016, Col. Robert Novotny, who was then the commander of the base's 48th Fighter Wing, predicted construction projects could face troubles getting funding or finding a skilled workforce to build the new facilities, and that F-35s likely wouldn't begin to arrive on base until at least 2021 or 2022. “For me, the concern I have when I look at Lakenheath is not the F-35,” he told Defense News in July 2016. “For me, the concern I have is: Are we going to be able to build enough stuff fast enough?” https://www.defensenews.com/smr/nato-air-power/2020/08/06/uk-facilities-for-american-f-35-jets-are-delayed-and-over-budget/

  Countering missile threats means addressing the present while planning for the future

  By: Ian Williams In 2017, I helped author the CSIS report “Missile Defense 2020,” a broad look at the history, status and future of the U.S. homeland missile defense system known as Ground-based Midcourse Defense. The report argued that the establishment of GMD had put the United States in an advantageous position relative to the North Korean missile threat, but this advantage would be short-lived if the United States failed to improve GMD through incremental milestones and regular testing. GMD has had some notable achievements with this strategy. The Pentagon, however, seems to be moving away from this proven approach to GMD, attempting great leaps rather than manageable steps. This riskier approach could make the United States less secure over the near and long term. Until recently, GMD had been following a well-defined road map, with good results. After a series of flight-test failures from 2010-2013, the Missile Defense Agency began a rigorous effort to root out anomalies within the system's Ground-Based Interceptors, or GBI. MDA carried out a successful intercept in 2014, followed by intercepting an intercontinental ballistic missile-class target for the first time in 2017. In 2019, GMD engaged an ICBM target with a salvo of two GBIs, marking another first for the system. MDA also expanded the fleet to 44 GBIs and is constructing a new Long Range Discrimination Radar in Alaska to provide the system much-needed sensor support. These achievements were supposed to be followed by an incremental modernization of the GBIs. The plan was to incorporate a new Redesigned Kill Vehicle around the year 2020. The RKV would be similar in concept to those currently deployed but incorporate new technologies and nearly 20 years of lessons learned. Another part of the plan was to give the GBIs a new booster, one that gave the war fighter the option of using either two or three stages, thereby providing the system more time and space to engage incoming missiles. MDA also set its sights on a set of longer-term objectives. These goals included a space-based sensor layer for tracking missile threats, and a GBI equipped with multiple kill vehicles that would greatly expand the capacity of the GBI fleet. While the volume kill concept had great appeal, MDA recognized the need for a developmental step between the current kill vehicles and a more advanced, unproven concept. Historically, U.S. missile defense has done best when pursuing steady, achievable goals. The highly successful Aegis Ballistic Missile Defense program, for example, has consistently adhered to the mantra: “Build a little, test a little, learn a lot.” The RKV program, however, ran into delays. Yet, rather than continue trying to fix the program, the Pentagon opted to abandon it and skip directly to a more advanced, multi-kill vehicle approach called the Next Generation Interceptor. NGI is an ambitious, 10-plus year endeavor that carries significant risk. In the near term, it means that the president's goal to add 20 more GBIs to the fleet will go unmet, as those GBIs were supposed to be capped with RKVs. Any expansion to the GBI fleet before 2030 will require the design and construction of a modernized unitary kill vehicle of some kind. Absent any effort to expand or modernize the GBI fleet, homeland missile defense will likely fall behind the North Korean missile threat while NGI matures over the next 10 years. The decline will increase U.S. vulnerability to coercion by North Korean leader Kim Jong Un at a time when the U.S. military is scrambling to address Chinese and Russian aggression. Furthermore, a major delay of NGI a decade from now (or worse, a failure for NGI to materialize at all) would leave the United States with a fleet of GBIs falling rapidly into obsolescence, squandering decades of resources and effort. To be clear, the United States should continue developing NGI. Missile threats to the U.S. homeland continue to grow at an alarming pace, in quantity and complexity. But the Pentagon and Congress should support these longer-term efforts while still investing in nearer-term options that keep U.S. homeland defenses current to North Korean missile capabilities, hedge against NGI failure and preserve U.S. investments in the GMD system. A potential path forward may lie in the Senate's version of the fiscal 2021 National Defense Authorization Act, which contains draft language that would require the deployment of 20 additional GBIs equipped with an interim, unitary kill vehicle by 2026. Three years ago, we titled our study of GMD “Missile Defense 2020” because we believed that this year would be the start of a new chapter in U.S. homeland missile defense. Obviously, much has changed with the cancellation of RKV. Yet, despite all its challenges, this year may still provide the opportunity to make the kind of decisions that will strengthen our national security in the near and long term. https://www.defensenews.com/opinion/commentary/2020/06/24/countering-missile-threats-means-addressing-the-present-while-planning-for-the-future/
