WASHINGTON — The U.S. Air Force has added two new technical issues to the KC-46 tanker's list of problems, potentially throwing a wrench into the projected delivery of the first tanker in October.
The service confirmed to Defense News on Sept. 17 that both deficiencies are category-1 , the most serious designation of technical problems, and revolve around the tanker's refueling boom system.
At this point, the Air Force is unsure whether the two problems will be solved in time for KC-46 manufacturer Boeing to deliver the first tanker next month, said Air Force spokeswoman Ann Stefanek.
“Boeing and the program office are still reviewing the test data and assessing the risk and potential solutions to these deficiencies, and proceeding in parallel to aircraft delivery,” she said in a statement.
The first new deficiency, which the service has labeled “No Indication of Inadvertent Boom Loads,” refers to situations where boom operators unintentionally provide an input into the flight control stick that induces loads on the boom while it is in contact with a receiver aircraft. The KC-46 currently has no way to notify that operator that this is happening.
The second deficiency was found when pilots of receiver aircraft reported that the boom is too stiff during the part of the process when the receiver plane moves forward into the fuel transfer zone.
“We discovered these deficiencies during the course of flight testing,” Stefanek said. “As the program progresses through receiver certification testing, we are still in discovery phase with the tanker/receiver pairs. ... The test team is still writing the test reports, but submitted the DRs [deficiency reports] in advance to assist in accelerating root cause, corrective action development.”
In a statement, Boeing said that it continues to work with the Air Force to determine a path forward.
“These are not safety of flight issues and we are confident in the unmatched capabilities of the KC-46 tanker aircraft," the company said. "To date we have completed more than 4,000 contacts during flights with F-16, F/A-18, AV-8B, C-17, KC-10 and A-10 aircraft. The refueling system has been tested extensively — we have a well-tested system that works.”
The Air Force can accept tankers at its own discretion, with or without active deficiencies. However, both Boeing and the Air Force have worked under the assumption that the service will not do so until all category-1 issues have been worked out or downgraded to category-2, which signifies that a workaround has been put into place.
The news of two more deficiencies is a blow to Boeing, which had been hoping to deliver the first tanker in October after finally coming to an agreement with the Air Force earlier this year on a proposed schedule. The KC-46 program has been notoriously above cost, and Boeing's fixed-price contract with the Air Force has forced it to pay out more than $3.4 billion to cover those overruns.
It has also run years behind schedule: The company was initially slated to deliver the first 18 certified tankers by August 2017. Boeing now has until October 2018 to meet that deadline — called required assets available— but will almost surely miss it, as the Air Force does not have the resources to absorb 18 new tankers in a month.
Over the past year, Boeing has been racing to resolve three additional category-1 deficiencies. Two involve the tanker's remote vision system, or RVS, a series of cameras and sensors that allow the boom operator to direct fuel into a receiver aircraft.
Unlike legacy tanker operators, KC-46 boomers will be unable to look out a window in order to see the refueling process happen — making them entirely reliant on the RVS. However, certain lighting conditions make it difficult to see the receiver aircraft's receptacle, leading to incidents where the boom has scraped the plane being refueled.
To fix the issue, Boeing has developed and tested a fix to the RVS' software. The Air Force is currently reviewing that data, and both RVS-related deficiencies are still in effect.
The final issue involves the system centerline drogue system, which has a mechanical lock that sometimes inadvertently disconnects during a refueling. Boeing plans to create a software fix to ameliorate that problem, too, but it remains a category-1 deficiency.

Andrew Eversden The Army has moved the Lockheed Martin-made electronic warfare pod to the build and evaluation phase of the operational system, as it bolsters its electronic warfare capabilities. The second phase agreement is worth nearly $75 million, according to the Consortium Management Group's Jan. 30 award listing, which made the award on behalf of the Army. Lockheed Martin's electronic warfare pod, known as the “Air Large” piece of the Army's Multi-Function Electronic Warfare family of systems program, is mounted on an MQ-1C Gray Eagle drone. It provides commanders with jamming capabilities as well as electronic support, or sensing of the electromagnetic spectrum. The defense contractor developed a prototype as part of the first phase of the project it won in January 2019 under an $18 million contact. “Our internal research & development programs have resulted in first-of-its-kind converged technologies that are at the forefront of realizing our customers' urgent need and vision for combined cyber and electronic warfare (EW) capability and dominance,” Deon Viergutz, vice president of Lockheed's Spectrum Convergence division, said in a statement. The company has been testing the pod as part of the Army's Cyber Blitz exercise. Army officials plan to have the capability deployed to combat aviation brigades in 2022. The pods are expected to play a critical role on the battlefield with near-peer adversaries, such as Russia and China. “The air pod solutions are very important, especially when you start going against a near-peer competitor. The main reason why is because you start now dealing with more of an [electronic intelligence] ELINT threat than with a strictly commercial threat,” Col. Kevin Finch, program manager for electronic warfare and cyber within Program Executive Office Intelligence, Electronic Warfare and Sensors, told C4ISRNET in October last year. https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/04/29/the-army-is-moving-forward-with-its-electronic-warfare-pod

WASHINGTON — The U.S. Army is close to triggering a competition for both a light and medium robotic combat vehicle by releasing a request for product proposals before the Thanksgiving holiday, according to Brig. Gen. Ross Coffman, the head of combat vehicle modernization for the service. The plan is to award one contract to one company to build a light variant, and repeat the process for a medium-sized robotic combat vehicle, or RCV, in March 2020. Then each company will deliver four prototypes for evaluation and testing in 12 months from contract award, Coffman told Defense News in a recent interview.. The Army anticipates a large pool of applicants based on a recent evaluation of eight different vehicles on a course at Texas A&M University's RELLIS campus, and because the response to a request for whitepapers for each variant was fruitful. The caliber of vehicles at the physical demonstration was higher than expected. Companies “really took it seriously” and brought vehicles that weren't just “modified, off-the-shelf” versions, Coffman said. Instead, the robots were “closer to purpose-built than we ever imagined,” he added. The Army is focused — across all three weight classes of robotic vehicle under pursuit — on a chassis rather than a vehicle as a whole. The idea is to integrate mission systems onto a common chassis for each weight class. On the heavyweight side, the Army completed a major experiment last month at Camp Grayling, Michigan, where four robotic versions of the M113 armored personnel carrier was evaluated for ground robotic capabilities. At the event, which will be followed by rigorous testing and evaluation at Aberdeen Proving Ground, Maryland, four robotic combat vehicles moved across the battlefield in a wedge formation. Soldiers controlled the platforms to keep them out of harm's way. “They came online, identified an enemy and then the humans called for fire based on the sensors on this robot,” Coffman said. “And then, once the artillery went in, the robots continued to traverse the terrain and engaged with direct fire against an enemy, destroying that enemy, all while the humans were in sanctuary controlling the battlefield.” The exercise demonstrated to Coffman that heavy RCVs can reduce the risk to soldiers on the battlefield. Once Army Test and Evaluation Command can put each vehicle through its paces, the platforms will head to Fort Carson, Colorado, in March 2020. “We're going to put these in the hands of soldiers and they're going to — they're going to get them dirty, they're going to execute tactical operations and they are going to fight against a live [opposing force],” Coffman said. “They are going to take them to the gunnery, and we're going to see all of the capabilities they can do.” After that phase, the Army plans to evaluate four M113s as well as four medium and four light RCVs that will form a company and execute tactical formations as the Army builds up its capability, according to Coffman. In 2023, the Army will evaluate purpose-built heavy variants with the medium and light RCVs also in a company formation, Coffman added. https://www.c4isrnet.com/2019/10/15/us-army-nears-competition-that-could-lead-to-robots-directly-engaging-the-enemy
