USAF Opens Bidding Phase Of B-52 Re-Engine Competition

Steve Trimble May 20, 2020

The U.S. Air Force has kicked off a three-way competition to re-engine the entire 76-aircraft B-52 fleet from 2021 to 2035.

The request for proposals (RFP) released on May 19 invites bids from GE Aviation, Pratt & Whitney and Rolls-Royce to supply 608 engines to replace each of the eight, 60-year-old, 16,000 lb.-thrust P&W TF33 turbofans on the heavy bomber.

GE can choose between the CF34 or Passport engine or offer both. P&W has proposed the PW800. Rolls-Royce will offer a military version of the BR.725.

The Air Force RFP lays out a two-step selection process. In step one, companies must submit “virtual” prototypes of their engine, meaning a digital design with integrated models for manufacturing, performance and sustainment.

Step 2 calls for the traditional engine source selection process, which will be informed by the data from the virtual prototypes and an integration risk analysis completed in the first step.

The Air Force has said the TF33 engines that now power the B-52 cannot be sustained practically beyond 2030. The Cold War jet, meanwhile, is expected to continue operating beyond 2050, outliving the B-2 and B-1B fleets scheduled for retirement in the 2030s.

Armed with a new class of hypersonic and long-range missiles, including the nuclear Long-Range Stand-Off Weapon, the B-52 will perform the standoff mission, while the B-21 penetrates into contested airspace.

    To keep weapon sales in place, US offers new options for payment

    By: Aaron Mehta WASHINGTON — The United States is developing new options for arms customers as a way to ensure allies and partners don't drop planned procurements as the world economy remains in shock from the impacts of COVID 19. Among the options, according to outgoing Defense Security Cooperation Agency head Lt. Gen. Charles Hooper, are allowing foreign countries to finance arms procurement through U.S. bank loans and altering existing payment schedules to stretch the costs over time. “The bottom line here is, we are willing to work with our allies and partners, when they raise the challenges that they have, to find ways for them to continue to buy American and to ensure that they can pay for the equipment along a payment schedule that reflects their own economic conditions,” Hooper said. During an exclusive exit interview with Defense News, Hooper declined to say which countries have already approached his agency about economic impact from the disease, but said that there are “certainly” customer nations that have reached out. “There are partners that, we're already seeing that they are having challenges. So we're standing ready to work with them. As soon as we can gain an appreciation and the understanding of the challenges, we can find ways to help them,” Hooper said. Hooper talked with Defense News two weeks before his Aug. 3 retirement. He is succeeded by Heidi Grant, the head of the Defense Security Technology Administration, a move that marks the first time a civilian has led the office since a previous agency was recognized into the current DSCA structure in 1998. The general expressed no concerns over that move, in large part, he said, because of Grant, a fixture in the international security cooperation world. Grant will have to hit the ground running, given the potential impact from COVID on the world economies. The good news, Hooper said, is that by March, DSCA had concluded that the global economy would be hurt by the disease and set up an interagency working group, called the Operations Planning Group, to study program-level impacts from global trends and develop solutions. The first step Hooper's team took was to revise the collection process of foreign payment in order to make them “a bit more flexible, to accommodate those partners that may be having some economic difficulties or may have reprioritized their budgets towards for example, economic recovery and away from defense.” Those options include delaying payments on planned procurements to future years, creating new payment plans for ongoing procurement efforts, and returning funds currently on deposit with the United States to the customer nations as well as new financing strategies. “One of the things we did is we are allowing our partners to draw on standby letters of credit from foreign banks operating in the United States, according to U.S. banking rules,” Hooper explained. “That offers a nation an opportunity to draw, for example, in that case, a standby letter of credit on one of their banks that operates in the United States, under United States banking rules, which ensures that there's no fiduciary risk to the United States.” DSCA officials had been considering adding such an option for some time, but the economic downturn pushed the agency to start offering it for customer nations, Hooper added. Lucie Béraud-Sudreau, director of the Arms and Military Expenditure Programme at the Stockholm International Peace Research Institute, said that option sounds different from funding plans that have existed for some time in Europe, where specific entities in countries are responsible for guaranteeing arms-recipient states' loans thanks to the state treasury. “There are a number of economic factors globally, that we anticipate will likely have an impact on country's abilities to move forward,” Hooper said. “Obviously, energy prices are lower, and those countries all over the world that specialize in energy are going to see a fall in revenue. We see countries that, as a result of the pandemic, are having to shift funds from their defense budgets to more domestic missions like economic recovery and other things.” In addition to oil-reliant nations in the Middle East, Béraud-Sudreau said to watch the Pacific region, where “many countries have already decided to cut their military spending for this year, and planning decreases for 2021.” Indonesia, Thailand, South Korea, and the Philippines are among the nations that have already announced plans to cut defense spending, while Singapore is seeing delays in weapon deliveries due to supply chain issues. “If there are limited orders in 2020-2021, there will be repercussions later on, as these companies work on long-term projects. Hence the pressure, on both sides of the Atlantic, for the defense sector to be part of economic recovery packages and high levels of military expenditure,” she said. Over the course of his time at DSCA, Hooper oversaw almost 18,300 Foreign Military Sales actions, including 5,800 new agreements and various amendments and modifications to existing agreements, according to agency figures. He reduced three different surcharges on customers, saving customers millions of dollars as well. Also, timelines shrunk, with DSCA offering 50 percent of all new FMS cases that flow through the process to partner nations in 49 days or less by Hooper's exit. And while Hooper did not want to preview what weapon sales totals for fiscal 2020 will be, he did say that the United States remains “on a very positive trajectory... We remain the global partner of choice. And I'm very optimistic that we're going to continue to see positive trends in our foreign military sales this year and in the years to come.” https://www.defensenews.com/pentagon/2020/08/04/to-keep-weapon-sales-in-place-us-offers-new-options-for-payment/

    UK shoots for new laser weapons against drones, missiles

    By: Andrew Chuter LONDON – Britain is planning to invest up to $162 million developing three directed-energy weapon demonstrators, including one aimed at killing drones, the Ministry of Defence has announced. The MoD said it had notified industry this week, in what is called a Prior Information Notice, of its intention to procure two laser-based demonstrators and a radio-frequency weapon to “explore the potential of the technology and accelerate its introduction onto the battlefield.” The British look to start the procurement process later this year and hope to have the new systems ready for trials in 2023. A spokesman for the MoD said it's too early to talk about any other timelines or exactly how the weapons development work will be procured. In a statement the MoD said it was forming a new joint program office and is now recruiting personnel to manage the program. The demonstrators are part of the MoD's ‘Novel Weapons Programme,' which is responsible for the trial and implementation of innovative weapon systems. The new arms are expected to reach the frontline within 10 years. The British already have a laser-based technology development effort underway. A £30 million ($37 million) technology demonstrator program known as Dragonfire was awarded to an industry consortium in 2017. Missile maker MBDA, Qinetiq, BAE Systems, Leonardo and others are involved in the industrial effort. The Defence Science and Technology Laboratory is leading the effort from the MoD side. Initial trials on Dragonfire are scheduled to take place this year. The spokesman said that while Dragonfire is about “assessing the viability of the technology, the new work will be looking at issues like size, functionality and exactly how they integrate on existing platforms.” The new program will include two high-energy laser demonstrators. One onboard a ship for air and surface defense applications and a similar laser mounted on a land vehicle for short-range air defense and counter-surveillance applications. The third program is aimed demonstrating a high-power radio frequency weapon mounted on a land vehicle against aerial drones and to counter enemy movements. The weapon is designed to disrupt and disable an adversary's computers and electronics. The MoD statement said Britain already has over 30 years' experience in radio-frequency and directed- energy weapons “during which time the UK has become a world leader in developing new power generation technologies and a global hub for the performance testing and evaluation of these systems.” “The new systems are expected to be trialed in 2023 on Royal Navy ships and Army vehicles but, once developed, both technologies could be operated by all three services. The armed forces will use these exercises to get a better understanding of DEW, test the systems to their limits, and assess how they could be integrated with existing platforms," said the MoD. The MoD released images of the laser weapons mounted on a Type 26 frigate and a Wildcat naval helicopter. The new program still leaves the British playing catch-up in the deployment of laser weapons. The U.S. Navy trialed a laser weapon on an operational warship several years ago and is now planning to install a high-energy laser and integrated optical dazzler with surveillance system on the destroyer Preble in 2021. On the land side, German defense contractor Rheinmetall has been developing a laser weapon for several years and recently undertook comprehensive trials with a weapon station suitable for mounting on a platform like a Boxer armored vehicle. https://www.defensenews.com/global/europe/2019/07/09/uk-shoots-for-new-laser-weapons-against-drones-missiles/

    Daily Memo: Powering Down

    Guy Norris As the airframers go, so goes the aircraft engine industry. After spending most of the past decade accelerating production to keep pace with unprecedented airliner delivery rates the engine makers have spent the past month in reverse thrust. But as production lines slow, and in some cases come to a full stop, the grim guessing game about the industry's post-COVID-19 pandemic future can begin. For every engine company, anchored midway between their own supply chains and Airbus, Boeing and Embraer in particular, all scenarios paint a bleak picture and the potential impact of the virus-triggered crisis is alarming on at least three key levels. Near term, all must weather the storm and rapidly shrink capacity by 40% or even more to match the new realities of the slower airframe production rates now expected for the next couple of years. Second, having long since focused the core of their business models on the aftermarket, they must adjust to significantly lower revenues from a near term reduction in demand for maintenance, repair and overhaul (MRO) services. Third, with nearly all their resources dedicated to survival, reduced revenues and spending trimmed, development of new engines and propulsion technology is expected to slow significantly—at least in the near term. However, all the manufacturers know that in the mid-to-longer term the environmental pressures on performance will return and so will the relentless demand for lower emissions and greater innovation. Already committed programs will therefore continue, albeit potentially stretched over longer test and development schedules. From a volume perspective, GE Aviation and Safran's CFM joint venture is expected to see the greatest change. Having delivered 1,736 LEAP-1s and 391 CFM56-5/7s in 2019, output from the combined French and U.S. operations will decline significantly in 2020 in lockstep with urgent reductions in production at Airbus and Boeing. CFM, which was previously on track towards a planned annual production rate of more than 2,000 LEAP-1s by the end of 2020, cannot comment on numbers while its parent companies remain in a dark period prior to earnings calls at the end of April, but is expected to slash this target by around half. GE Aviation, which was already expecting a leaner 2020 before the COVID-19 pandemic because of delays to the GE9X-powered Boeing 777-9 and slow-downs to the GE90-115/GEnx-1 powered 777-200LR/300ER and 787 programs, is eyeing the even more troubling impact of the crisis on its aftermarket business. Although around a quarter of GE Aviation's revenues come from its military and other businesses, just 30% comes from commercial engine sales. A much larger portion of its revenue—approximately 45%—comes from MRO services. While some programs, like the CFM56 for the P-8 maritime patrol aircraft as well as military fighter engine efforts, will continue much as before, the company has already taken drastic action to stem losses by furloughing half of its engine manufacturing workers for four weeks. This move, taken in early April, followed an announcement in late March that it was reducing its workforce by 10% (around 2,500 employees), in direct response to the collapse of its MRO workload which the company estimates will be down by around 50% through mid-year at least. However, given the exodus of around two-thirds of the world's airline fleets into storage (almost 17,000 aircraft), the short to medium outlook for engine MRO would be described as dire at best. Compounding the issue for many of the OEMs is that the higher value aftermarket engines powering the widebody fleet, particularly the older generation Airbus and Boeing models, now look increasingly unlikely to ever return to service—at least in their existing guise. For Rolls-Royce, this problem is particularly acute as the UK engine maker focused increasingly on the widebody market over the past decade, widening its exposure to reliance on the support revenue from aftermarket work on older fleets of 747 and 777s as well as older A330s. With full-time premature retirement a possibility, including the previously unthinkable sunsetting of relatively young Trent 900-powered A380s as well as the rapid decline of the RB211-535 powered 757 and Trent 500-powered A340-600 fleets, the company can no longer bank on the expected rebound in deferred maintenance coming out of the crisis. Rolls has also rushed to mitigate losses by enacting measures aimed at saving at least £750 million ($937 million) in cash this year. These include a 10% salary cut for the global workforce and canceling dividend payments. Further moves are expected as the company adjusts to rate reductions announced by Airbus involving the Trent-powered A330no and A350-900/1000, as well as yet-to-be announced rate cuts for the Trent 1000-powered 787 which will shortly be revealed in detail by Boeing. Pratt & Whitney, now part of Raytheon Technologies, is similarly impacted across the board with production of the PW1000G geared turbofan reduced for the A220/A320neo families and commercial revenues hit by falling aftermarket revenues for the PW2000/PW4000 and V2500. Measures such as 10% pay cuts through year-end, as well as furloughs, are being introduced while research and development spending is being frozen. Deliveries of military engines, in particular the F135 for the F-35 fighter and PW4000 for the KC-45A tanker remain unaffected. The early retirements of the PW4000, as well as some CF6-powered fleets, is also significantly impacting revenues for German engine maker MTU. https://aviationweek.com/air-transport/aircraft-propulsion/daily-memo-powering-down
