  Here’s why Boeing is getting $55.5M to fix a problem with the Air Force’s new tanker

  By: Valerie Insinna WASHINGTON — The Air Force will pay up to $55.5 million for Boeing to redesign the KC-46's boom, but it will cost more than that to field a fix to the problem. According to a Aug. 2 contract announcement, the award will pay for a “system level hardware and software critical design review of the boom telescope actuator redesign,” and Boeing will receive $21 million of the proposed award value immediately. But because the contract has yet to be definitized, Boeing could receive up to $55.5 million once terms of the deal are cemented. And since initial award only covers the redesign of the boom — not the costs of testing, fabricating and retrofitting the new booms on existing aircraft — it stands to reason that the Air Force will owe additional money to Boeing to completely fix the issue. Unlike the other remaining critical deficiencies on the KC-46 program, the Air Force has agreed to foot the cost of fixing the boom problem, as it is a change in the service's initial requirements. Boeing's current boom design meets international standards for thrust resistance, and the Air Force accepted that design at Milestone C in 2016, when the KC-46 was cleared for production. But later flight tests demonstrated that the boom produces too much thrust resistance to refuel the A-10, necessitating a change in design. In January, an Air Force official told Defense News the process of redesigning and manufacturing the new booms could take about two years. The Air Force plans to buy 179 KC-46s over the life of the program. After years of delays due to technical issues, the service signed off to accept the first tanker in January, which was then delivered to McConnell Air Force Base, Kan., later that month. The KC-46 made its first flight for the initial operational test and evaluation phase on June 4 at McConnell AFB. Boeing is on the hook to pay for the other major critical deficiency: a redesign of the Remote Vision System, a collection of cameras and sensors that allow the boom operator to steer the boom into the fuel receptacle of the receiving aircraft. The service became aware of this problem after pilots experienced difficulties directing the boom during refueling, sometimes scraping the surface of the receiver aircraft — a mistake that could compromise the low observable coating of stealth aircraft. Despite this issue, the Air Force has decided to accept KC-46 tankers so that pilots can begin training with the new aircraft. However, the service is withholding up $28 million per plane in order to incentivize Boeing to move quickly on a redesigned RVS. About $360 million has been withheld so far, according to Defense One. https://www.defensenews.com/air/2019/08/06/heres-why-boeing-is-getting-555m-to-fix-a-problem-with-the-air-forces-new-tanker/

  A key milestone of the Air Force One replacement program was conducted using virtual tools. It won’t be the last.

  By: Valerie Insinna WASHINGTON — The Air Force One replacement program has hit a major development milestone, and it did so without the in-person meetings that have become more risky in the age of the novel coronavirus, the U.S. Air Force's top acquisition official said on Thursday. The Air Force recently completed the critical design review for the Presidential Aircraft Replacement program, which will replace the legacy VC-25A Air Force One planes with a new variant of the Boeing 747-8 known as the VC-25B. Although the classified portions of the review still must be done via face-to-face meetings in secure spaces, much of it was accomplished using virtual tools and applications, said Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics. “I was really excited that the team was able to shift their CDR [critical design review] and go virtual,” he told reporters in an April 16 teleconference, adding that more programs will shift toward using virtual meetings to conduct key reviews and milestones even after the COVID-19 pandemic subsides. “I don't know if it makes any sense to do CDRs, at least at an unclassified level, outside of tools like this. And we're working really hard to provide the same capabilities at the secret level,” he said. While Roper did not detail which communication tools were used by the program office to conduct the CDR, he described it as being very similar to widely used applications like Zoom, where the briefer can share PowerPoint slides and participants can share thoughts and questions via a written chat function. “It allows a greater level of productivity than a meeting itself,” he said. “In meetings, you have someone speaking and you want to get a question in, but you've got to wait for them to stop, and then everyone else wants to ask a question. It's hugely inefficient. It's just such an antiquated way of sharing information that is ingrained in us.” The Air Force One replacement drew considerable attention in 2016 after then-President-elect Donald Trump tweeted that the program was too expensive at more than $4 billion and should be canceled. After Trump held numerous meetings with Dennis Muilenburg, who led Boeing at the time, the Air Force awarded Boeing a $3.9 billion contract to modify two 747s into VC-25B jets. However, once all costs are included — such as buying a new hangar for the aircraft and the base cost of the 747s themselves — the Air Force will pay $5.3 billion, according to Defense One. That expense includes an $84 million contract awarded to Boeing on Wednesday to modify Boeing 747 technical specifications and manuals to the VC-25B configuration. Roper doesn't project any schedule delays to the program as a result of COVID-19, which has pummeled prime contractor Boeing's commercial business and caused a temporary pause to certain defense production lines. In February, Boeing began modifying the two 747s slated to become VC-25Bs at its facility in San Antonio, Texas. During the first part of the process, Boeing will cut out large pieces of the aircraft's skin and structure and replace that with two specially designed “superpanels,” according to an Air Force release. The VC-25Bs will also receive upgrades including enhanced electrical power, specialized communication systems, a medical facility, a customized executive interior and autonomous ground operations capabilities. The new Air Force Ones are expected to be operational in 2024. https://www.defensenews.com/air/2020/04/16/a-key-milestone-of-the-air-force-one-replacement-program-was-conducted-using-virtual-tools-it-wont-be-the-last/

  India takes next step toward new 155mm towed howitzers

  The towed gun systems are to be no heavier than 15 tons, and they must be able to fire existing 155mm rounds to a distance of 40-plus kilometers.
