Developing larger and longer-ranged fighters, weaponizing the Boeing KC-46 fleet, and possibly fielding a new type of unmanned, small and stealthy tanker are all now in discussion by U.S. Air Force leaders, assistant secretary of the Air Force Will Roper said on Sept. 23.
As the head of acquisition, technology and logistics, Roper said he and the new chief of Air Mobility Command, Gen. Jacqueline Van Ovost, are “excited” now about the direction of the long-troubled KC-46 program, as the Air Force and Boeing continue to finalize the Remote Vision System 2.0 upgrade.
The KC-46's turnaround, Roper said, is allowing acquisition and mobility officials to turn their attention to addressing another Air Force refueling problem: How to solve a yawning gap between refueling capacity and operational need for inflight refueling, especially at the forward edge of a ring of contested airspace, where large and, for now, relatively defenseless aircraft such as the KC-46 are most vulnerable.
Building a more survivable and responsive air refueling capability that can be used in a contested war zone was the focus of a meeting this week between Roper and Van Ovost, he said.
“One of those next strategic questions for the Air Force is going to be can you defend a tanker against an onslaught of fighters who know that every tanker you kill, it's like killing a lot of fighters or bombers or drones that it supports,” Roper said.
Roper prefers not to take a one-size-fits-all solution, such as a single major new acquisition program that buys only one type of aircraft. Instead, the Air Force should evaluate the solution to the contested aerial refueling problem as an architecture, with multiple options that can be dialed back and forth.
One option for reducing demand on tankers is a new fighter aircraft that is designed to carry more fuel.
“Maybe having [the] small, currently sized fighters is not the way to go in [the] future,” Roper said. “And since we're all abuzz with digital engineering and thinking about what the future fighter force could look like, thinking about bigger fighters is a natural question.”
Another way to make the KC-46 fleet more survivable, and thus operate closer to the forward edge of contested airspace, is to weaponize the aircraft, he said.
“We don't put weapons and sensors on tankers to shoot down aircraft, but the current KC-46 is a big airplane with the ability to mount sensors and weapons under the wings,” Roper said. “We just don't do it because we can use a fighter combat air patrol to defend high-value assets.”
The Air Force also may need a different kind of tanker in the future, he said. Two options are possible: A larger aircraft than the KC-46 that could carry more fuel, but needs to stay farther away from potential threats, or much smaller, unmanned and stealthy “micro-tankers” that could operate much closer or even inside defended airspace, Roper said.
“I expect that as we really look at airpower in the truly contested environment that we'll be looking at fuel very strategically,” Roper said.

Burak Ege Bekdil ANKARA, Turkey — The Canadian government's decision to suspend export of key drone parts to Turkey has once again thrown a spotlight on Turkey's ongoing efforts to develop a self-sufficient defense industry. Turkish President Recep Tayyip Erdogan often boasts at party rallies that his governance since 2002 has reduced Turkey's dependency on foreign weapons systems from 80 percent to 30 percent. There is truth in that, although the actual percentages remain a mystery, mainly due to the difficulty of defining what is truly a local or national system. Most Turkish “national” systems depend on various degrees of foreign input, often including critical parts only available abroad. The T129, an “indigenous” attack helicopter, is a Turkish variant of the Italian-British AgustaWestland A129 Mangusta chopper. Turkey's local industry has no engine technology. The “national” new generation tank Altay is facing major delays, due to the lack of a foreign engine and transmission system. Turkey's first “indigenous” landing platform dock, the TCG Anadolu, will enter into service next year, but the $1 billion or more ship is being built under license from Spain's Navantia. Even Turkey's biggest success in the past few years, a locally-built drone known as the Bayraktar TB-2, features critical foreign parts — an issue now in the spotlight following Canadian Foreign Minister Francois-Philippe Champagne's Oct. 5 announcement to suspend export permits of drone technology to Turkey, which is backing Azerbaijan in the recent Azeri-Armenian military conflict. Champagne issued the pause in exports alongside an order for his ministry to investigate claims that Canadian drone technology is being used in the fighting. The decision followed an announcement by disarmament group Project Ploughshares, which warned the multimillion-dollar exports of high-tech sensors and targeting technology produced by L3Harris WESCAM in Burlington, Ont., are in direct contravention of Canada's domestic laws and its international obligations under the United Nations Arms Trade Treaty, to which the Trudeau government acceded almost exactly a year ago. L3Harris WESCAM, the Canadian subsidiary of U.S. defense giant L3Harris, is one of the world's leading producers and exporters of electro-optical/infra-red (EO/IR) imaging and targeting sensor systems — both of which are featured on the Bayraktar drones. “These sensors are integral for their ability to conduct drone warfare, which they've done increasingly... in the past few years across several conflict zones,” Kelsey Gallagher, a Project Ploughshares researcher, told Radio Canada International. “If the exports of these sensors were completely halted, then Turkey would not have the sensors necessary to conduct modern airstrikes.” “This [the suspension of Canadian supplies] may cause disruption in the production line,” said one local aerospace analyst, “unless substituted immediately.” “There may be some other foreign suppliers to be used as a stop-gap solution," the analyst added. "But this is mostly a Western (including Israeli) technology and may not reach Turkish manufacturers due to political reasons.” Turkey's top procurement official, however, has a solution. Ismail Demir, president of the defense procurement agency SSB, twitted Oct. 6, the day after the Canadian decision, that Turkey would soon start to mass produce the CATS electro-optical system, to replace the WESCAM technology used in the TB-2 drone. CATS will be produced by military electronics specialist Aselsan, Turkey's biggest defense company. Demir said that Aselsan has also begun to work on developing a future version of the CATS system. Demir also talked up another new indigenous ambition: Project Özgür, or “free” in Turkish. Özgür is part of a broader upgrade effort designed to extend the life of the Turkish F-16 fleet. “This program aims to completely nationalize electronic systems on our F-16s,” Demir told the HaberTurk newspaper Oct. 6. The full upgrade work will also involve structural and avionic modernization. Turkey views the F-16 upgrades as a stop-gap solution before it builds its own indigenous fighter, the TF-X. But the TF-X effort has moved at a crawl, with no notable progress in the past few years, due mainly to the lack of an engine to power the planned fighter. https://www.defensenews.com/global/europe/2020/10/13/canadian-block-on-drone-parts-shows-turkeys-defense-industry-still-not-independent/

Nathan Strout WASHINGTON — The U.S. Air Force Research Laboratory has opened a lab focused on developing materials for new deployable space structures. Construction on the Deployable Structures Laboratory, or DeSel, began in December 2019 and opened Oct. 29, 2020. Scientists and engineers moving into the $4 million lab at Kirtland Air Force Base, New Mexico, will continue the work of the Spacecraft Component Technology Center of Excellence, which has a history of developing spacecraft structure materials. DeSel contains specialized equipment and a climate-controlled, vibration-isolated laboratory capable of testing spacecraft structures up to 20-by-15 meters, allowing AFRL to further research and develop high-strain composite materials. “I'm excited to have a facility that was specifically built for testing novel deployable space structures,” Benjamin Urioste, research engineer and lead for the Integrated Structural Systems team, said in a statement. “With the push toward hybrid architecture and smaller satellites, high packing efficiency structures and the ability to bring large satellite capability to small satellites is more important than ever.” “This new class of high strain composite enabled structures requires new ground test facilities,” he added. “Satellite deployments are nerve-wracking, one-shot endeavors and the high-fidelity ground testing that will take place in the DeSel is critical to ensuring on-orbit success.” Spacecraft Technologies Division chief Mark Roverse said the structures, made possible by high strain composites, "will enable new mission paradigms for the U.S. Space Force.” “AFRL has led development of high strain composites for deployed spacecraft structures, and we are excited to see the new mission capabilities that are being enabled,” Roverse added. One spacecraft in development that will benefit from these new structures is AFRL's Space Solar Power Incremental Demonstration and Research project. With the SSPIDR project, the lab wants to build a spacecraft capable of collecting solar energy on orbit and then transmitting that energy to forward-operating bases via radio frequency. Northrop Grumman was awarded a $100 million contract to support space-based experiments informing SSPIDR's development. The Space Force is testing that technology on the X-37B, the service's secretive spacecraft, but DeSel's work will provide the materials needed to build the SSPIDR craft. “This innovative research will help us to deliver the essential energy our warfighters need at the right place at the right time,” explained Col. Eric Felt, director of the AFRL's Space Vehicles Directorate. “Some of the first structures that we look forward to testing in this new lab are those required for our Space Solar Power Incremental Demonstration and Research (SSPIDR) project, one of our top priority programs.” https://www.c4isrnet.com/battlefield-tech/space/2020/11/04/air-force-research-laboratory-open-new-space-lab/
