Air Force study on future aerial refueling tanker could start in 2022

WASHINGTON — The Air Force could begin to lay out its vision for a future aerial refueling tanker, previously known as KC-Z, as early as next year, the head of Air Mobility Command said Monday.

The service intends to conduct an analysis of alternatives for an advanced aerial refueling aircraft in fiscal year 2022, AMC commander Gen. Jacqueline Van Ovost said during a Defense Writers Group meeting with reporters. That study will help the Air Force determine precisely which capabilities a future tanker will need to to operate in more heavily contested battlefields against the threats posed by nations such as Russia and China.

“We're thinking about the near peer [competition], and what we need for a near peer [competition],” she said.

Key to that discussion is figuring out how much of the aerial refueling process can be performed without a human pilot or boom operator onboard the plane to fly it or give other aircraft gas.

“Is going to be autonomous? Is it going to be pilot on the loop [or] pilot in the loop capability?” asked Van Ovost. “Is it going to be small? Is it going to be large? What kind of [self protection] is it going to have? What kind of electromagnetic spectrum capabilities is it going to have to both protect itself and enhance the lethality of the Joint Force while it's out there?”

In April, Will Roper, then the Air Force's top acquisition official, told reporters that an agreement with Boeing for a new and improved KC-46 vision system could pave the way for autonomous aerial refueling. The addition of 4K high-definition cameras, modern processors and LiDAR (light detecting and ranging) sensors would help the new system accumulate much of the data necessary for a computer to correctly calculate all the variables that need to be solved for safe aerial refueling.

“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,” Roper said then.

The Air Force is not the only service interested in automated aerial refueling. The Navy is flight testing the MQ-25 Stingray aerial refueling drone — which, like the Air Force's new KC-46 tanker, is built by Boeing. The Navy eventually hopes to operate the MQ-25 onboard aircraft carriers, where it will be used to extend the range of fighter jets like the F-35C and F/A-18EF Super Hornet.

Van Ovost acknowledged the Air Force is still years away from being able to hold a competition for the platform formerly known as KC-Z. After the Air Force completes its procurement of 179 KC-46s — which, if its current buy rate holds, will occur around the 2027 timeframe — the service will buy a non-developmental “bridge tanker,” she said.

That effort, which replaces the KC-Y program, will likely be a battle between Boeing and an Airbus-Lockheed Martin team, which joined forces in 2018 to market Airbus' A330 Multi-Role Tanker Transport to the U.S. Air Force. Both teams are expected to offer upgraded versions of their current aerial refueling aircraft.

Van Ovost did not say when that competition will begin.

Along with tackling questions about its future tanker, the Air Force is also set to begin a business case analysis whether to pursue contracted aerial refueling to support U.S. military training and test activities across the contiguous United States.

After holding a Dec. 19 industry day with interested vendors, Air Mobility Command conducted a study into the feasibility and affordability of commercial air refueling services and submitted a proposal to Air Force leadership.

However, Air Force leaders want more information before making a final decision, and have asked for a comprehensive business case analysis that would finalize a requirement for all of the services' needs, Van Ovost said. The study would come up with options for various contracting models — which could include tankers that are leased to the government or contractor-owned and operated — as well as hammer out details on Federal Aviation Administration certification requirements.

“We're working with headquarters Air Force to finalize the parameters for the study, and then likely will be contracting out that study,” Van Ovost said. “And for expectation's sake, it does take a while. These kinds of business case analysis we have seen take 18 months, so we are going to put pen to paper and take a very close look at it.”

The Air Force’s robot pilot returns to the skies
Nathan Strout A developmental robot pilot that transforms manned aircraft into unmanned systems is flying again after the Air Force Research Laboratory took its ROBOpilot out for a test flight at Dugway Proving Ground, Utah, Sept. 24. ROBOpilot's name belies the simplicity of the program. In order to turn a manned aircraft into an unmanned one, AFRL simply replaces the human pilot with a robot who interacts with the aircraft controls the same way a human would: it can pull the yoke, press pedals to control rudders and brakes, adjust the throttle and flip switches. In addition to the robot's own internal GPS and inertial measurement unit, the system scans the gauges on the dashboard for information about the aircraft and its position, processing that information with a computer to independently fly the plane. Importantly, ROBOpilot requires no permanent modifications. All operators need to do is remove the pilots' seats and replace them with ROBOpilot. And if users determine that they want to return the aircraft to a manned mission, ROBOpilot is simply removed and the pilots' seats are reinstalled. The robotic system is the result of a Small Business Innovative Research (SBIR) award granted to DZYNE Technologies by the AFRL's Center for Rapid Innovation (CRI). Despite a successful first flight in August 2019, the system was later grounded after it maintained damage during a landing mishap. “The CRI and DZYNE team analyzed the findings and incorporated the recommendations to ensure the success of this latest test,” said Marc Owens, CRI's program manager for ROBOpilot. “We determined the cause of the mishap, identified the best course of corrective action and we're very pleased to be flight testing again.” Since then, ROBOpilot has been cleared to fly again and installed in a new Cessna 206. On Sept. 24, the system returned to the skies for a 2.2 hour test flight over Utah. “Since this is a completely new build with a different Cessna 206, we re-accomplished the flight test points completed on our first flight last year,” Owen explained. “ROBOpilot is too good an idea to let the mishap derail the development of this technology.” https://www.c4isrnet.com/unmanned/2020/09/28/the-air-forces-robot-pilot-returns-to-the-skies/

Navy Mulling How to Make Surface Fleet Flexible, Lethal
By: Otto Kreisher WASHINGTON, D.C. — A panel of senior Navy civilian officials said the planning efforts for the future combat fleet was focused on making the fleet more flexible, interoperable and lethal. There also is an emphasis on open architecture to make it easier, quicker and cheaper to upgrade combat systems, they said. Those priorities would reduce the cost of sustaining the fleet going forward, the officials said at the American Society of Naval Engineers' annual Technology, Systems & Ship symposium on June 19. Michael Stewart, deputy director for integrated warfare systems, said his job was to look at the available capabilities across all the different surface platforms to make the fleet more capable and lethal. He also would ensure that all requirements going forward were clearly tied to the National Defense Strategy, since “we can't afford to fund everything.” John Hootman, the deputy director for surface warfare, said he was looking at the architecture for the future surface combatants in the 2030-2040 timeframe, when the Ticonderoga-class cruisers and some of the early Arleigh Burke destroyers would be retiring. But, he said, “we can't know what we'll need until we know how we'll fight.” In response to a question, Hootman praised the creation of the Surface Development Squadron, which will help in that effort to determine how the future fleet would fight. Hootman also emphasized the need to look at capabilities across the fleet, not at specific platforms, to promote commonality across the fleet, including a common combat system that could equip the whole range of surface combatants and even the amphibious ships. But that focus on common systems also could apply to the hull, mechanical and electrical elements of future ships. “The push for commonality is key.” Another official extended that quest to communications systems, arguing that every different circuit in the fleet reduces capacity, flexibility and the ability to integrate operations in the strike group. Steven Dries, filling in for Rear Adm. Steven Pardoe, director of integrated warfare, noted that the capabilities that ships would need in the future will change, which makes it all the more important to field systems that can be modernized with software changes, rather than having to tear out hardware. Hootman stressed the same thing as a way to more efficiently modernize ships and gain commonality. He also cited the savings in training sailors to operate and maintain systems that are common across platforms. https://news.usni.org/2019/06/19/navy-mulling-how-to-make-surface-fleet-flexible-lethal
