  Price Drop: Lockheed Pitches $80M F-35A to Pentagon

  BY MARCUS WEISGERBER That's the cheapest price yet for the Air Force version of the fifth-generation jet. Lockheed Martin is offering to come down more than 10% on the price of the least-expensive F-35 as it negotiates the largest sale yet of Joint Strike Fighters. The company is offering to sell the Pentagon about 100 F-35As — the version flown by the U.S. Air Force and most allies — for less than $80 million each, down from $89.5 million apiece in the deal signed last September. That price point suggests the company will meet its 2020 price targets for the warplane, whose lengthy development and higher-than-expected initial costs have drawn much criticism. The 100 F-35A are part of a block buy of three production lots of the jets — in all, roughly 450 jets. The order will include F-35Bs for the Marine Corps, F-35Cs for the U.S. Navy, and a variety of the jets for allies. “We currently have an offer submitted to the Department of Defense for Lots 12-14 that is below the $80 million F-35A for lot 14 in 2020, per our longstanding commitment,” company spokesman Mike Friedman wrote in an email Tuesday. “This represents equal or less than the procurement cost of legacy jets, while providing a generational leap in capability.” The latest round of F-35 negotiations come as the Air Force is planning to buy new Boeing-made F-15 Eagle fighters for the first time in two decades. While the new Eagles would replace existing F-15s, Lockheed has arguedthe F-35 is a cheaper alternative and offers stealth and other technology that comes standard in a more modern, fifth-generation warplane. The proposed purchase of three batches of jets simultaneously is meant to get a better price than past years' annual purchases of a few dozen of the jets. A 2018 Rand study put the potential savings at more than $2 billion. Lockheed has delivered more than 385 F-35s to the U.S. Air Force, Navy, Marine Corps and American allies. “As we ramp up production, each year we have lowered cost, reduced build time, improved quality and on time delivery,” Friedman said. “Moving forward, we are focused on and taking action to further reduce costs across both production and sustainment.” https://www.defenseone.com/business/2019/05/price-drop-lockheed-pitches-80m-f-35a-pentagon/156825

  The data challenge of space-based hypersonics defense

  By: Nathan Strout Managing data is the biggest challenge to developing a new space-based sensor layer that would help detect hypersonic weapons, the director of the Missile Defense Agency said Oct. 7. The agency is working toward building the Hypersonic and Ballistic Tracking Space Sensor, a layer of sensors on orbit that would be capable of detecting and tracking hypersonic weapons that the nation's current missile defense architecture was not designed to handle. The new system will be built into the Space Development Agency's constellation of low earth orbit satellites. For Vice Adm. Jon Hill, the director of the agency, designing the sensors for the system is a surmountable engineering issue and evolving commercial launch capabilities mean it will be easy to get the technology to space once its ready. The real challenge is “the passing of track data between different space vehicles and maintaining track and dealing with clutter.” Hypersonic weapons are dimmer than traditional ballistic missiles, making them harder to detect. The sensors will have to be able to remove that clutter, detect the threat and then pass their data to the next LEO sensor, which will pick up the object as it travels around the globe at hypersonic speed. Allowing for that data flow from sensor to sensor is essential to the effective operation of the system. Hill compared the complexity of that data transfer to his time in the Navy, where information had to go between moving vessels, but the data issue with satellites is magnitudes of order more difficult. “When you put yourself on a moving body that's moving, not at 30 knots but at a much higher speed, you know, maintaining the stability of that track, being able to pull the clutter out of it, determining how much you want to process up on orbit versus how much you want to feed down and process on the ground, then how you distribute. Do you distribute directly from the sensor? Do you control the weapon from space? Or do you take it to the ground station and do it there? There [are] different trades, and we'll probably do it differently in a lot of different ways because that adds to the overall resilience of the system,” Hill said speaking at a Center for Strategic and International Studies event October 7. Finding the right answers to those questions will be a priority for the MDA as it works to works to get the system on orbit quickly. “It's going to be a great capability. We just need to get it up there as soon as we can and rapidly proliferate,” Hill said. https://www.c4isrnet.com/battlefield-tech/space/2019/10/09/the-data-challenge-of-space-based-hypersonics-defense/
