With laser weapons coming, the US Navy’s newest super carrier has space and power to spare

By: David B. Larter

ABOARD THE AIRCRAFT CARRIER GERALD R. FORD IN THE VIRGINIA CAPES — The U.S. Navy is trying to find an alternative to shooting down anti-ship missiles with other missiles, and the aircraft carrier Gerald R. Ford could prove useful in this pursuit.

A major difference with Ford over its Nimitz-class predecessors is its twin A1B nuclear reactors that produce more than three times the electrical power of the reactors on Nimitz — more than 100 megawatts.

That means Ford, with survivability questions looming over aircraft carriers, can support large, power-sucking equipment such as lasers, according to Capt. J.J. Cummings, the Ford' commanding officer.

“When you talk about innovation in the Navy, this is where it lives,” Cummings said, referring to his ship. “We're lighter — designed lighter — than Nimitz class.

“Nimitz class, she's barreling down pretty good now with a lot of stuff on her, and her electric plant is almost at maximum capacity. We're light and designed to have excess capacity in our electrical system to bring future systems on board.”

That's a big advantage for the class, and it's one of the reasons the Navy has pursued the Ford class despite the controversies over buggy new technology and cost overruns. The Ford class is essential for the survivability of carriers, said James Geurts, the Navy's top acquisition official.

“Part of the reason Ford is so important is that it gives you the flexibility to generate the next generation of systems you'll need to ensure the carrier can continue to stay survivable,” Geurts said.

Killing missiles with missiles

Bryan Clark, a retired naval officer and analyst with the Center for Strategic and Budgetary Assessments, said Ford could use a boost in the survivability department and the Ford's powerful reactors could help them get there.

“To improve the self-defense on carriers, you could put lasers on there to support that short-range, self-defense capacity,” Clark said. “Because the big problem with lasers right now is power management. You can build a three or four hundred-kilowatt laser, but for one, it's a big footprint so you have to find a ship big enough to put it on; and two, you have to have the power to actually supply it. So you're going to need a capacitor bank somewhere on the ship or you need a generator big enough to provide it continuously. On the Ford, you'd get that."

Clark has argued for years that the Navy needs to get away from trying to shoot down missiles with missiles because a saturation attack from Russia, China, Iran, North Korea or anyone else who might have cause to attack a U.S. Navy ship could force a cruiser or destroyer to expend all its missiles and still not have defeated the threat.

That's where shorter-range missiles such as the Evolved Seasparrow Missile, which can be packed four per cell in a vertical launch system, and lasers can have a big impact, even if it means the ship has to let missiles get uncomfortably close to the ship before it's taken down.

“I think lasers could make a difference for Ford because the technology is pretty mature, you could fit it on the ship and it would address a big challenge for carriers, which is air defense,” Clark said. “You could put several lasers on there and really give a boost to your air defense capacity.”

However, it's unlikely lasers could address all threats faced by carriers, Clark said.

“It would be effective for cruise missiles up to maybe the supersonic cruise missiles,” Clark said. “Of course, it would also work against small boats and things like that. It may not work that well against hypersonic missiles or ballistic missiles.”

Three European air forces approve performance benchmarks for next-gen fighter jet
By: Sebastian Sprenger COLOGNE, Germany — The air forces of Germany, France and Spain have agreed on a set of performance benchmarks to help their governments guide the development of a next-generation fighter jet set to fly in 2040, the German military announced Tuesday in a statement. The document, approved earlier this month, is meant to help officials identify what features from a collection of 10 possible system architectures are worth keeping when the time comes to settle on a path forward for the Next-Generation Weapon System, or NGWS. That system, with the manned next-gen fighter at its heart, is slated to become the central element of the Future Combat Air System, or FCAS, the most ambitious and expensive weapons program in mainland Europe. As envisioned, a small fleet of attack and surveillance drones, or “remote carriers,” would accompany each jet, and all elements would be interlinked by an artificial intelligence-powered “combat cloud,” according to a project description. The 10 different system architectures for NGWS currently in the mix lean in different directions — for example, when it comes to armaments, maneuverability and range of the main jet and its companion drones, the German Bundeswehr statement explained. The three air force top officials — Lt. Gen. Ingo Gerhartz of Germany, Gen. Philippe Lavigne of France and Javier Fernandez of Spain — also agreed on a “Common Understanding Connectivity,” a guide for connecting national systems into the future FCAS scenario. The document will enable the program's partner nations to “synchronize” their respective development programs, according to the German statement. The industry leads for the Future Combat Air System program, Airbus of Germany and Dassault of France, unveiled a mock-up of the future fighter jet at the Paris Air Show last year. The plan is to begin testing a prototype in 2026. Earlier this year, France and Germany formally kicked off the next phase of the overall program, with each government contributing $85 million toward the development of technology demonstrators. German lawmakers, who fear an overtly strong French industry influence in the FCAS program, have linked the project to progress on the Main Ground Combat System, another highly visible bilateral program aimed at building a common battle tank. France has the lead on the next-generation fighter, while Germany leads the tank project. The German parliament's strategy of keeping a close watch on the aerial program by approving only relatively small tranches of money has Dassault CEO Eric Trappier worried about the ability to hit deadlines, French newspaper La Tribune reported last week. Speaking before a French Senate committee in mid-May, Trappier proposed a Franco-German programming law to ensure a more rapid development pace, according to the newspaper. https://www.defensenews.com/global/europe/2020/05/26/three-european-air-forces-approve-performance-benchmarks-for-next-gen-fighter-jet/

Air Force study on future aerial refueling tanker could start in 2022
By: Valerie Insinna 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 December 2019 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.” https://www.defensenews.com/air/2021/02/02/air-force-study-on-future-aerial-refueling-tanker-could-start-in-2022

Germany wants its own version of DARPA, and within the year
By: Sebastian Sprenger COLOGNE, Germany — Germany Defence and Interior ministry officials are pushing for the creation of a new agency this year that will study disruptive technologies relevant to Germany's defense and security. A decision on the way forward is expected “shortly,” a Defence Ministry spokesman told Defense News on Wednesday. Planning is underway to get the green light from the Finance Ministry, a necessary step because the agency would be set up as an “in-house” limited liability corporation, according to the spokesman. If all goes according to plan, insiders believe Cabinet-level consideration of the effort could come as early as September. While there is no official word on the exact timing, the spokesman said creating the agency is firmly on the calendar for 2018. The full name for the outfit is “Agentur für Disruptive Innovationen in der Cybersicherheit und Schlüsseltechnologien,” or ADIC. Its name first popped up in the coalition-government agreement between Chancellor Angela Merkel's Christian Democratic Union and Social Democrats in March. The document postulated that the agency, overseen by the two ministries for interior and exterior security, would help ensure Germany's “technological innovation leadership.” Also requested in that document was the creation of an “IT security fund” that would help protect related key technologies. Defence Minister Ursula von der Leyen referred to the coming agency in a speech in May, equating its purpose to that of the Pentagon's Defense Advanced Research Projects Agency, otherwise known as DARPA. She presented the idea as part of a wider plan toward deep-futures thinking on cybersecurity matters, which also includes a study program at the Bundeswehr University in Munich. Under the relatively new shift to emphasize all things cyber in the German military, the Defence Ministry's Cyber Innovation Hub, created last year, is slated to survey the domestic technology startup scene for ideas with potential military application. Asked by Defense News what status the upcoming agency will accord to the field of artificial intelligence, ministry officials responded that such projects “generally” would be eligible to receive temporary funding if they are deemed relevant to the mission. Much remains unknown about the German military's approach to artificial intelligence, famously dubbed by Russian President Vladimir Putin last year as the technology that holds the key to ruling the world. “The research area of artificial intelligence and potential applications by the Bundeswehr are being substantively reviewed,” the defense spokesman said. Whether the new ADIC or any of the existing organizations inside the Defence Ministry would get involved remains an open question, he added. Some experts fear Germany is falling behind the the United States' and China's enormous efforts in artificial intelligence, though government officials have said they believe the country's talent base and emerging policy framework can ensure success. A whitepaper released Wednesday by the Cabinet agency leading the push on AI, the Ministry of Education and Research, proclaimed the goal of making German-made AI a “seal of quality recognized all over the world.” The document will lead to a more comprehensive strategy by late November. It makes no explicit mention of any military or defense applications. Efforts already exist within the armed forces and the wider government to employ data-mining and predictive-analysis tools, which fall under the broader definition of artificial intelligence. For example, defense officials have touted experiments with a forecasting application developed to predict worldwide crises. Officials also try to play up the Bundeswehr's geekiness in its search for new recruits. A current online marketing campaign showcases the career field of a Bundeswehr University professor employing AI techniques to analyze terror attacks for patterns. https://www.defensenews.com/global/europe/2018/07/18/germany-wants-its-own-version-of-darpa-and-within-the-year
