WASHINGTON — Last week's deal between Boeing and the U.S. Air Force on a fix for the KC-46 could pave the way for the tanker to refuel other aircraft without a person needed to manually control the process, a top service official said Thursday.
On April 2, Boeing agreed to fix the KC-46's troubled Remote Vision System by creating an overhauled RVS 2.0 with new hardware and software. Air Force acquisition executive Will Roper told reporters those changes would include the addition of 4K high-definition cameras that will display imagery in color as well as modern processors and LiDAR (light detecting and ranging) sensors that will help improve depth perception.
“A proper RVS like that is right on the doorstep to autonomy,” Roper said. “All you have to do is take that data that tells the world inside the jet the reality of geometries between the airplane and the boom outside the jet. Once you have that, you simply need to translate it into algorithms that allow the tanker to tank itself.”
The KC-46's Remote Vision System has been a thorn in the side of the aircraft program since 2017, when issues with the system were first discovered. The RVS is basically a suite of cameras, sensors and software that is supposed to allow boom operators sitting inside the aircraft to safety steer the boom into the aircraft needing fuel. But in certain conditions, the system produces distorted imagery that increases the risk of the boom hitting another aircraft.
The new LIDAR system will be key to fixing that problem, said Roper, who likened it to a backup camera on a car that also provides cues to a driver for parallel parking or assessing whether a vehicle is aligned flush to a curb.
“We'll have something very similar to that for the boom operators, so telling them are they left, right and how close are they getting to the airplane,” he said. “[It's] something very intuitive and easy to work with, and I think that will help significantly with them understanding their distance [from the other aircraft] because LIDAR is extremely accurate.”
Because Boeing is locked into a firm fixed-price contract for the development of the KC-46, it will have to pay for the upgrade to RVS 2.0 out of its own pocket, as the Air Force maintains that the current system does not meet requirements.
But the service is so confident in the prospect of using the RVS 2.0 as a stepping stone to an autonomous tanker that it included an option in last week's agreement to fund the development of technologies that enable autonomous or semiautonomous refueling.
“We have added an engineering change proposal into the deal with a not-to-exceed threshold of $55 million, so that when RVS 2.0 is done, we can then take the next step beyond 2.0 to develop those autonomy algorithms and install them if we think we can certify them for safe use,” Roper said.
“We took that step because, one, we're excited about being on the doorsteps of autonomy and, [two], we wanted to send a clear signal in the deal that this is our tanker for the future,” he said.
If the Air Force decides to move forward with those design changes, more will need to be done to hammer out the contractual details, said Jamie Burgess, Boeing's KC-46 program manager.
“There was no commitment one way or another on who pays for what. But there's definitely a strong partnership between Boeing and the Air Force as far as developing this technology,” he said.
Autonomous refueling capability has been of increasing interest to the Air Force over the past few years, as sensing and artificial intelligence technologies grow by leaps and bounds. Boeing previously signaled it could include such technology as part of a menu of potential upgrade options for the KC-46, as reported by FlightGlobal in 2018.

By: Valerie Insinna ORLANDO, Fla. — The U.S. Air Force will know by the end of this month whether it will kick-start a competition for aerial-refueling services, the head of Air Mobility Command told Defense News. The service is in the final stages of a feasibility study that is evaluating whether the Air Force should buy commercial tanking services to support day-to-day needs for training and testing, said Gen. Maryanne Miller in an exclusive Feb. 28 interview. “The interest is high on the commercial side. The commercial companies who are considering this are really waiting to see the feasibility study, which will be completed in March,” she said. “The interest is high on the outside. I talked to a few vendors yesterday that was asking me when the study is going to be done. We're all waiting for that.” The study will help the Air Force determine whether it is cost-effective to use commercial aerial-refueling services as well as help set parameters on how a contract could be structured. However, Miller said, industry-operated tankers would not conduct combat or other overseas operations, and instead would be used exclusively for tasks in the continental United States such as augmenting training or for test and evaluation missions that AMC does not always have the capacity to fill. AMC believes its requirement will amount to about 6,000 hours per year, although the study could influence that number. Currently 14 companies have indicated interest in competing for the opportunity, she said. If the service decides to move forward with a competition, it believes it will be able to move from a contract award to an initial operating capability using a few aircraft in about a year, Miller said. “I love the idea. I hope the feasibility proves positive for us. That way we can get our requirements out there, we can start receiving proposals and then work that process as defined. We're optimistic,” she said. “That would be exciting to relieve some of the tension and stress on our force.” Getting Congress to agree to fund aerial-refueling services could be a hard sell, especially as the service considers paring back some of its own capacity. To free up funds for other priorities, the Air Force proposed retiring 16 KC-10s and 13 KC-135s in fiscal 2021. However, the idea has come under fire from U.S. Transportation Command — which has sought funds to buy back 23 of those tankers — as well as lawmakers who question whether the Air Force would be taking on too much near-term risk. But Miller contended that having the flexibility of commercial aerial-refueling services could relieve pressures on the military's own tankers, filling the gap for U.S. missions when there is high demand abroad. “It really just relieves and fills that market of the service missions we just don't get to today. Some of that is readiness-related,” she said. It also could have a positive impact for acquisition programs, as there will be more aerial-refueling resources available for test and evaluation, allowing test points to be completed more quickly and efficiently, and let the Air Force ensure it doesn't wear out its legacy KC-135s too quickly. “Having one more option is just really, really important.” https://www.defensenews.com/air/2020/03/05/the-us-air-force-is-getting-ready-to-make-a-decision-about-commercial-aerial-refueling-services/
