    Done deal: Boeing will have to rip and replace KC-46 sensor and camera systems on its own dime

    By: Valerie Insinna WASHINGTON — Boeing and the Air Force have finalized an agreement to fix the KC-46 aerial refueling tanker's most serious technical problem, Defense News has learned from multiple sources familiar with the matter. The agreement puts an end to years of negotiations between the Air Force and aerospace giant over the nature and extent of redesign work needed to correct the Remote Vision System, the collection of cameras and sensors that provide boom operators the imagery needed to steer the boom into another aircraft and safely transfer fuel. Perhaps more importantly, the deal paves a path that will allow the service to deploy the KC-46 in combat in the mid 2020s — something Air Force leaders have bristled against with the tanker in its current form. The Air Force and Boeing have agreed on a two-phased roadmap to address RVS technical issues, said one source familiar with the agreement. The first phase allows Boeing to continue providing incremental improvements to software and hardware that will fine-tune the imagery seen by the boom operator, the source said. The second phase — which will take years to complete — involves a comprehensive redesign of the RVS where its hardware and software will be almost completely replaced with new color cameras, advanced displays and improved computing technology. Boeing and the Air Force both declined to comment on the matter. Unlike legacy tankers, where boom operators can look out a window in the back of the aircraft and rely on visual cues to steer the boom, operators in the KC-46 are completely dependent on the imagery provided by the RVS. Although Air Force operators say the system works in most conditions — and provides a safer way to offload fuel during nighttime conditions or bad weather — certain lighting conditions can cause the RVS imagery to appear warped and misleading, contributing to cases where the boom accidentally scrapes the surface of another aircraft. That could be a safety hazard for the pilot of the plane receiving gas, and it could also potentially scrape the stealth coating off a low observable jet, eroding its ability to evade radar detection. Under the terms of Boeing's fixed-price firm contract and previous agreements with the service, the company will be financially responsible for paying for the entirety of the redesign effort. The company has already exceeded the $4.9 billion ceiling on the contract, and has paid more than $3.5 billion in cost overruns as technical problems have mounted. Boeing is the system integrator for the RVS and designs its software, while the system's cameras and sensors are primarily designed by Collins Aerospace. Air Force's acquisition executive Will Roper is expected to brief congressional staff on the deal this afternoon, sources said. Afterwards, the service is expected to release additional information about the deal. Boeing delivered the first KC-46 tanker to McConnell Air Force Base, Kan., in January 2019, but the Air Force has withheld $28 million per aircraft upon delivery due to the RVS issues. So far, the company has delivered 33 tankers to the service. https://www.defensenews.com/breaking-news/2020/04/02/done-deal-boeing-will-have-to-rip-and-replace-kc-46-sensor-and-camera-systems-on-its-own-dime

    USAF’s Future Fighter Plan May Limit Growth, Study Says

    By Jen DiMascio The U.S. Air Force's plan for acquiring future fighter aircraft may crimp the service's ability to grow in the future, a study of the USAF's force structure plans indicates. The study, “The Air Force of the Future,” compares the service's force structure plans during times of peak budgets—in fiscal 2020 and fiscal 1985. In fiscal 2020, a budget of $205 billion could support 5,300 aircraft. This is a little more than half of the number that the same amount of money, adjusted for inflation, could support in 1985—9,400. The same holds true for the number of personnel, the report says. It was released Oct. 29 by Todd Harrison, director of the Aerospace Security Project at the Center for Strategic and International Studies, which examined three different studies of the size of the future force. As part of the report, Harrison drills further into the Air Force's spending habits to find that one factor underlying the inability to afford a larger force is the increase over time in operation and maintenance costs. “The average O&M cost per plane is 74% higher today in real terms than in fiscal 2001,” the report says. Looking more closely at maintenance costs, he finds that the most expensive aircraft to operate are the smallest fleets, such as the Boeing E-4 Advanced Airborne Command Post aircraft, the Northrop Grumman E-8 Joint Surveillance Target Attack Radar System and Northrop's B-2 bomber. “This is because the fixed costs of operating the fleet are distributed across more aircraft in large fleets, which brings down the overall ownership cost per plane,” the report says. “The data suggest that the Air Force could reduce operating costs by divesting aircraft that are maintained in small numbers in the current inventory and consolidating the capabilities they provide into common multimission platforms.” Air Force acquisition chief Will Roper is recommending an acquisition strategy dubbed the “digital century series.” It aims to build new fighter aircraft designed to last 3,500 flight hours in batches of hundreds, rather than the current model of pursuing advanced technology for an aircraft type that will last for decades. But Harrison estimates that the operation and sustainment cost of sustaining five different aircraft types of 72 aircraft, or 360 total aircraft, would cost about the same as sustaining 1,800 aircraft of the same type. “That's something the Air Force has got to consider,” Harrison said. “With the digital century series approach, they may end up with a bunch of small fleets and may limit the ability of the Air Force to grow in the future.” https://aviationweek.com/defense/usaf-s-future-fighter-plan-may-limit-growth-study-says
