The Air Force’s KC-46 tanker has another serious technical deficiency, and Boeing is stuck paying for it

By: Valerie Insinna

WASHINGTON — The Air Force on Monday logged another critical technical flaw for the KC-46 tanker, this time revolving around excessive fuel leaks.

Under its contract with the service, KC-46 manufacturer Boeing is responsible for paying for a fix to the problem, Air Force spokeswoman Capt. Cara Bousie said in a statement.

“The Air Force and Boeing are working together to determine the root cause and implement corrective actions,” she said. “The KC-46 program office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery.”

The problem was first discovered in July 2019, but the Air Force did not say why the issue had been escalated to Category 1 status — the designation given to problems with a significant impact on operations or safety. The service also did not immediately comment on questions about what sort of receiver aircraft were most involved with the deficiency or the severity of the problem.

A Boeing spokesman said that the Air Force had discovered 16 aircraft in need of repair, and that seven have already been fixed.

“The KC-46 fuel system is equipped with redundant protection for fuel containment. In some cases with this issue, aircraft maintenance crews are finding fuel between the primary and secondary fuel protection barriers within the system,” the company said in a statement.

Boeing is working with “utmost urgency” to address the problem and implement a fix to the remaining aircraft, the statement said. A Boeing spokesman added it would take about 10 days to retrofit each aircraft at the rapid response depot facility in San Antonio, Texas. The fix was also being incorporated into production line in Everett, Wash., which is currently undergoing a temporary suspension due to COVID-19.

The latest Category 1 deficiency brings the total up to four:

  • The tanker's remote vision system or RVS — the camera system that allows KC-46 boom operators to steer the boom into a receiver aircraft without having to look out a window and use visual cues — provides imagery in certain lighting conditions that appears warped or misleading. Boeing has agreed to pay for potentially extensive hardware and software fixes, but the Air Force believes it will system won't be fully functional until 2023-2024.
  • The Air Force has recorded instances of the boom scraping against the airframe of receiver aircraft. Boeing and the Air Force believe this problem is a symptom of the RVS's acuity problems and will be eliminated once the camera system is fixed.
  • Boeing must redesign the boom to accommodate the A-10, which currently does not generate the thrust necessary to push into the boom for refueling. This problem is a requirements change by the Air Force, which approved Boeing's design in 2016. Last year, Boeing received a $55.5 million contract to begin work on the new boom actuator.

Boeing's fixed-priced firm contract for the development of the KC-46 has a $4.9 billion ceiling that leaves the company responsible for any expenses billed in excess of that amount. So far, the company has paid more than $3.5 billion of its own money to fund corrections to ongoing technical issues.

    Marine Raiders adjust training, add online courses to weather COVID-19

    Shawn Snow Even Marine Raiders are feeling the impact of COVID-19 as the elite special operations unit headquartered in state under a stay-at-home order is being forced to adjust training to comply with state, defense and federal health guidelines. The Marine Raider Training Center aboard Camp Lejeune, North Carolina, is home to the seven-month Marine commando special operator school known as the Individual Training Course, which creates Critical Skill Operators who earn the 0372 military occupational specialty. While COVID-19 continues to rampage across the U.S., North Carolina Gov. Roy Cooper issued a stay-at-home order to stem the spread of the virus. According to the New York Times, there are 1,582 reported cases of COVID-19 across North Carolina. To comply with the governor's order, Marine Forces Special Operations Command says it has made adjustments to training to include restructuring the ITC course and adding online training where possible. “The ITC schedule has been restructured to ensure the safety and health of the two classes currently undergoing training. Some of the in-class material has been shifted to online learning, to include parts of the Basic Language Course,” Gunnery Sgt. Lynn Kinney, told Marine Corps Times in an emailed statement. The ITC course is a seven-month training evolution broken down into several phases that includes land navigation, patrolling, small unit tactics, irregular warfare and close quarters battle. MARSOC did not provide any other details regarding the restructuring of the ITC course. “Other parts of the training have been shifted to ensure COVID-19 response requirements,” Kinney said. https://www.marinecorpstimes.com/news/coronavirus/2020/04/02/marine-raiders-adjust-training-add-online-courses-to-weather-covid-19/

    Britain eyes a more lethal force in newly revealed defense modernization review

    By: Andrew Chuter LONDON — Britain is to rebuild weapon stockpiles, strengthen Joint Forces Command and earmark cash to rapidly innovate as part of a long-awaited defense modernization review revealed Tuesday by Defence Secretary Gavin Williamson. The defense secretary told Parliament on Dec. 18 that the review, known as the Modernising Defence Programme, would improve the lethality, reach and mass of the armed forces. However, he stopped short on detailing where the cash would coming from and who the long-term winners and losers might be in regard to capabilities and programs as priorities change. Although Williamson told lawmakers he would do “everything within my power to make sure that the U.K. remains a tier-one military power,” his statement disappointed some in the defense sector for its blandness. Labour, the main opposition party in Britian, called the statement “waffle” and said Williamson had done nothing to address a funding shortfall of between £7 billion and £15 billion (U.S. $8.8 billion and $18.9 billion) in equipment budgets over the next 10 years. Some analysts also felt the yearlong review had failed to deliver. “It's an announcement about future announcements, it's the [Ministry of Defence] keeping lots of option open, “ said Jon Louth, the director of defense, industries and society at the Royal United Services Institute think tank in London. “It's all about seeing what can be achieved in next year's governmentwide departmental spending review." Howard Wheeldon, a British-based defense commentator, said the review had “hardly a specific detail of anything that really matters other than some minimal strategic intentions to be found amongst the prose. Perhaps the best that can be said is that while it contains many strategic positives, loads of ambition and intent, at the very least it doesn't contain any new specifics in relation to planned cuts.” Alex Ashbourne-Walmsley of Ashbourne Strategic Consulting said the review was an “anti-climax.” “We have waited all year for this, and what we have is a very thin document. It's hard to fault the aspiration, but making it a reality is a different matter. Where's the money coming from?” she said. Ashbourne-Walmsley and Louth agreed the MoD's success, or otherwise, in securing additional funds when the government's departmental medium-term spending plans are agreed sometime next year is the key. “For the MoD, it's all about next year's departmental spending review. It's unfortunate that the moment the review came on the horizon, that invalidated most of the things that the modernizing defense review could have hoped to achieve,” Ashbourne-Walmsley said. “A lot of these plans are hostage to fortune in terms of the spending review [known as the comprehensive spending review], economic damage from Brexit and even a change of government,” she added. The MoD has secured an additional £1.8 billion in funding this year from the Treasury for spending on items like the nuclear deterrent, anti-submarine warfare and cipher capabilities, but the department still has considerable work to do to balance the books on a total budget slated to top £39 billion next year. The National Audit Office, the government's financial watchdog, reckons the MoD is at least £7 billion overcommitted on its 10-year, £186 billion equipment plan. But, the office admits, it could be a lot more. Williamson acknowledged the MoD had to create “financial headroom for modernization,” but told Parliament this could be achieved through efficiencies. “Based on our work to date, we expect to achieve over the next decade the very demanding efficiency targets we were set in 2015, including through investment in a program of digital transformation,” he said. Analysts here reckon that's an optimistic target without capability cuts; although there was no mention of any reductions in the statement. “We all know that you cannot [achieve efficiency targets] without taking the knife to something. So what we may be able to deduce or fear is that hidden out there somewhere is a chapter of probable announcements of what might yet be to come,” Wheeldon said. One thing appears: Spending priorities are set to change as the MoD reacts to the growing threat from potential adversaries. That includes rebuilding depleted weapons stockpiles. “To improve the combat effectiveness of our forces, we will re-prioritize the current defense program to increase weapon stockpiles. And we are accelerating work to assure the resilience of our defense systems and capabilities,“ Williamson said. “We will improve the readiness and availability of a range of key defense platforms: major warships, attack submarines, helicopters and a range of ISTAR platforms,” he added, without concrete details. Williamson also said Joint Forces Command capabilities are set to be upgraded. “A major new step will involve an improved Joint Forces Command that will be in a better position so that defense can play a major role in preventing conflict in the future and improve our cyber operations and capabilities across the armed forces, but also across government as well,” he said. “Our adversaries and competitors are accelerating the development of new capabilities and strategies. We must keep pace and conceive of our joint force as consisting of five domains — air, land, sea, cyber and space — rather than the traditional three,” he told lawmakers. The review might have been short on details, but the MoD is pledging to drive the military modernization effort with funding, albeit a small amount, for innovation. Britain already has a small defense innovation fund, which this year has £20 million to put toward projects in areas including unmanned air systems, virtual reality training and enhanced digital communications. The fund will grow to £50 million in the next financial year. New “Spearhead” innovation programs will apply cutting-edge technologies to areas including subsurface threats to submarines; intelligence, surveillance and reconnaissance capabilities; and command and control in the land environment. For now, the MoD is investing £160 million to create a transformation fund, but additional money may be available in the upcoming comprehensive spending review if Williamson can make the case for it. “I will ring-fence £160 million of MoD's budget to create this [transformation] fund available for innovative new military capabilities. I will look to make a further £340 million available as part of the spending review. This fund will be available for new innovative military capabilities, which allows us to stay one step ahead of our adversaries," Williamson argued. https://www.defensenews.com/global/europe/2018/12/18/britain-eyes-a-more-lethal-force-in-newly-revealed-defense-modernization-review
