USAF Discussing Larger Fighters, Weaponized KC-46, Roper Says

Steve Trimble

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.

    Défense : des Euroflir 410 pour les gendarmes aussi

    Jean-Marc Tanguy Safran Electronics & Defense va encore allonger la série des ventes de ses boules optroniques Euroflir 410. Cette fois, ce sont les gendarmes qui vont la retenir pour leurs Airbus Helicopters H160. Boules optroniques sur H160 A défaut de plan de relance, certains industriels français de la défense voient des commandes parfois imprévues tomber. C'est le cas pour Safran Electronics & Defense qui va encore allonger la série des ventes de boules optroniques Euroflir 410 : cette fois, ce sont les gendarmes qui vont la retenir pour leurs dix Airbus Helicopters H160. Un tiers de ces hélicoptères devra être opérationnel avant les JO de Paris en 2024. L'expérience Wescam Les gendarmes avaient fait confiance à Safran (Sagem à l'époque) pour leurs premières caméras embarquées, sur Ecureuil, mais leurs performances avaient vite perdu, et le système avait été retiré du service dans les années 2010, avec le matériel de transmission en temps réel afférent. La gendarmerie avait alors reporté son intérêt sur l'Américain Wescam. La boule MX-15 est efficace, mais a connu, en France en tout cas, des difficultés de service après-vente qui ont sans doute pesé lourd dans la balance. Restent les Fennec de l'Armée de l'Air Seulement, la préférence nationale post covid-19 y est aussi pour beaucoup, et il devient plus difficile de faire accepter des commandes de produits étrangers quand la France est productrice. Le choix de l'Euroflir 410 s'inscrit après les commandes françaises sur les Panther, puis le système de drone tactique de l'Armée de Terre (dont l'entrée en service est décalée de près de quatre ans/ndlr), puis les Dauphin loués par la Marine (une caméra pour deux hélicoptères), les quatre H160 de la Marine, et donc, désormais, la gendarmerie. La série n'est pas finie, Safran Electronics & Defense ambitionnant aussi de se placer sur les Fennec de l'Armée de l'Air.

    Lockheed-Dynetics team and Raytheon locked in battle to build 100-kilowatt laser for US Army

    By: Jen Judson HUNTSVILLE, Alabama — Raytheon and a Lockheed Martin-Dynetics team are now locked in a head-to-head battle to build a powerful 100-kilowatt laser for the U.S. Army, pushing the envelope on directed-energy capability development. And the Army is moving full-speed ahead with plans to select one winner to integrate its laser system onto the Family of Medium-Tactical Vehicles, or FMTV, in early 2019. The effort will culminate in a test of the entire system in 2022 at White Sands Missile Range, New Mexico. The Army began its effort to get a more powerful laser onto a vehicle less bulky than a Heavy Expanded Mobility Tactical Truck in 2016. Raytheon announced last month that it had won a $10 million contract to develop a laser for the Army's High Energy Laser Tactical Vehicle Demonstration program. Dynetics released a statement Aug. 6, just ahead of the Space and Missile Defense Symposium in Huntsville, Alabama, revealing it had won, along with its partner Lockheed Martin, the second $10 million development contract to build a laser for the HEL TVD program.
