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

By:

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.”

    General Electric wins $517 million contract to build engines for Army’s next generation helicopters

    By: Valerie Insinna WASHINGTON — General Electric Aviation beat the Advanced Turbine Engine Company — a Honeywell and Pratt & Whitney team — to win the $517 million award for the engineering, manufacturing and development phase of the Improved Turbine Engine Program, or ITEP. “We are honored to be chosen by the Army to continue powering their Black Hawks and Apaches for decades to come,” said Tony Mathis, president and CEO of GE Aviation's military business. “We've invested the resources and infrastructure to execute immediately, and our team is ready to get to work on delivering the improved capabilities of the T901 to the warfighter.” The fierce competition started more than a decade ago, and its outcome will influence Army rotorcraft for decades to come. GE's T901 engine is now set to replace the T700 used by the Army's legacy utility and attack helicopters, but could also potentially outfit the Army's next generation reconnaissance helicopter in the Future Vertical Lift family of systems. “The requirements documents for the [Future Attack Reconnaissance Aircraft] specifiesTHE ITEP engine. It has got the FVL stamp of approval,” Jim Thomson, Jr., acting deputy director for the Army's future vertical lift cross functional team, told Defense News in a recent interview. ITEP answers a number of problems that emerged as the Army operated Apaches and Black Hawks during combat in Afghanistan and Iraq. The AH-64 and UH-60 became heavier as the service added armor and other upgrades during wartime, and they flew in hotter conditions and higher altitudes than would normally be optimal. “The helicopters were originally designed to work at 4,000 feet on a 95-degree day, and they were flying them much higher than that,” Mike Sousa, GE's business development leader for advanced turboshaft engines, told Defense News in December 2018. “When you do that, you just don't have as much power from the engine.” The Army's requirements for ITEP were clear throughout the process: Design a 3,000 shaft horsepower engine that reduces fuel consumption by 25 percent and increases its service life by 20 percent compared to the T700, a 2,000 shaft horsepower engine. Both companies were awarded risk reduction contracts in August 2016, with ATEC getting $154 million and GE Aviation getting $102 million to further refine their designs. Both companies had already spent years conceptualizing new engines and developing novel tech. GE, the incumbent manufacturer of the T700, offered a single spool engine. Sousa said that configuration would help the company meet weight requirements while removing cost and complexity from the design. “Our fundamental approach there was how do we keep this engine as affordable as possible and as low weight as possible,” he told Defense News in 2018. “Helicopters are unique in that they fly into very dirty environments, very austere environments, unprepared landing strips, unprepared surfaces,” added Ron Hutter, GE's executive director of the T901 program. “They generate a lot of dust. You really want to look at the simplicity of the architecture in terms of maintainability. That's another aspect that drove us to stick with the single-spool configuration.” GE estimates that it's spent $9 billion in testing technologies relevant to the T901. ATEC had proposed a double spool engine it dubbed the T900. “We were disappointed to learn that the U.S. Army did not select our offering,” said Craig Madden, president of ATEC. “We believe that we offered the most advanced, capable and lowest risk engine for ITEP for the Army to improve the overall performance of its Apache and Black Hawk fleets.” https://www.defensenews.com/air/2019/02/02/general-electric-wins-517-million-contract-to-build-engines-for-armys-next-generation-helicopters

    Can France Eventually Replace Its Single Aircraft Carrier?

    by Robert Farley Follow drfarls on TwitterL Key Point: Paris has a long history of building aircraft carriers, including their current nuclear-powered Charles de Gaulle. If France wants to remain a relevant great power, it needs to think about what comes next after its carrier reaches retirement. France's first carrier entered service in the interwar period, but for a very long time the French navy trailed behind international counterparts in naval aviation. This changed in the Cold War, however, and today France operates the world's most advanced carrier outside of the U.S. Navy. How did France build its naval aviation force, what does it do today and what direction will France take next? The History of French Carriers Soon after World War I, France joined the international carrier community through the conversion of the battleship hulk Bearn. Although large, Bearn did not carry many aircraft and never actively participated in combat, even during World War II. The construction of two additional large carriers was suspended by World War II, but after the war the French navy gained access to light carriers transferred from Britain and the United States. Four in total, these carriers helped the French navy develop its naval aviation muscles. The next step was big; France constructed a pair of CATOBAR aircraft carriers, Clemenceau and Foch. Commissioned in 1961 and 1963, the ships displaced 30,000 tons and could carry around forty modern aircraft. A third carrier, the much larger Verdun, was cancelled before being laid down. Clemenceau and Foch, operating the F-8 Crusader and later the Super Etendard, would form the backbone of the world's second largest carrier force for the latter half of the Cold War. After nearly forty years of hard service, the two ships were decommissioned in favor of France's next carrier, the nuclear-powered Charles de Gaulle. https://nationalinterest.org/blog/buzz/can-france-eventually-replace-its-single-aircraft-carrier-122231
