    Lockheed CEO: Boeing’s F-15X won’t disrupt F-35 program

    By: Valerie Insinna WASHINGTON — Lockheed Martin has been given assurances by top Pentagon leaders that the F-35 program will not be negatively impacted by a potential U.S. Air Force buy of Boeing's F-15X, Lockheed CEO Marillyn Hewson said Tuesday. “If they choose to have an order of the F-15, it won't be at the expense of F-35 quantities,” she told investors during an earnings call. “I'm hearing that directly from leadership in the Pentagon, and I think that's an important point for me to make. It's not just our suspicion, but I've been told that directly.” The U.S. Air Force is expected to roll out a plan to begin buying new F-15s in its upcoming fiscal 2020 budget release. In December, Bloomberg reported the service intends to purchase 12 new F-15X aircraft in 2020 for $1.2 billion. On Friday, Gen. Dave Goldfein, the Air Force's chief of staff, confirmed to Defense News that the service will procure new F-15s if the budget grows enough to allow it, but that the F-35 program of record would remain the same with no slowdown to the buy rate. “I'm not backing an inch off of the F-35” Goldfein said. “The F-35 buy that we're on continues to remain on track. And I'm not interested in taking a nickel out of it when it comes to buying anything else in the fighter portfolio.” Goldfein added that the Air Force wants to increase fighter procurement to 72 aircraft a year. The Air Force has about 230 F-15 "C" and "D" models currently in service, and the F-15X will replace the portion of the fleet owned by the Air National Guard, according to Bloomberg. The new F-15 model will have new radar and electronic warfare equipment, the ability to carry more weapons, and include other improvements originally designed for Saudi Arabia's and Qatar's F-15s. If the service maintained a rate of one F-15X a month, it would be free to boost its F-35 production rate to 60 aircraft a year — a number that Air Force officials had cited as key for production ramp up. However, the FY19 budget forecast showed that the service would likely be unable to procure the F-35 in those quantities before FY23. “If we had the money, those would be 72 F-35s. But we've gotta look at this from a cost/business case.” Goldfein said. “An F-15 will never be an F-35. Never. But I need capacity.” Hewson's statement indicates that support for the F-35 continues to be strong both within the Air Force and among Pentagon leaders. However, earlier on Tuesday, acting Defense Secretary Patrick Shanahan told reporters he wants to see “more performance” from the F-35, although he did not specify particular areas of improvement. “I am biased towards giving the taxpayer their moneys' worth. And the F-35, unequivocally, I can say has a lot of opportunity for more performance,” said Shanahan, a former Boeing executive. When investors asked Hewson to respond to Shanahan's critique, the Lockheed CEO said the company remains on the same page with the Pentagon on the need to reduce the cost per plane. “We're on a path to drive it to an $80 million [unit cost] for the F-35A by full-rate production,” which is projected to begin in Lot 15 with deliveries starting in 2023, Hewson said. “So as long as we stay on our procurement rate plan — which by all accounts we're going to continue to ramp up at the rate that we envisioned — then we're going to continue to drive the price down."

    How low-Earth orbit satellites will enable connectivity across all domains of warfare

    Nathan Strout The Space Development Agency will provide the unifying element in the Defense Department's future Joint All-Domain Command and Control concept, pulling together tactical networks developed by the services with a constellation of low-Earth orbit satellites. With the JADC2 concept, the department envisions an overarching network capable of connecting sensors to shooters regardless of where they are located. That means U.S. Air Force sensors could feed data to U.S. Army shooters, or even National Reconnaissance Office sensors could send information to U.S. Air Force shooters. “Each of the services have their own way to incorporate [tactical networks], and JADC2 is just a way to make sure they all have the same networking infrastructure to talk to one another, essentially,” SDA Director Derek Tournear said at the C4ISRNET Conference on May 6. “We plug directly into [JADC2] as the space layer to pull all of that communication together.” Service efforts include programs like the Air Force's Advanced Battle Management System and the Army's TITAN ground system. What the Defense Department wants to ensure is that programs like these have a way to share data across the armed services. “All of those are reliant on a way to be able to have a back end to go in space to be able to communicate across one another and across back to [the continental United States], etc. That's where the Space Development Agency's transport layer comes in,” Tournear said. “In fact, in the defense planning guidance, Secretary Esper put out the edict that basically said the transport layer will be the integrating aspect of JADC2 to be able to pull all of this tactical communication together in space.” On May 1, the SDA released its solicitation for the first 10 satellites that will make up its transport layer — a space-based mesh network in low-Earth orbit. When fully developed, that transport layer will provide a global network that various sensors, shooters and tactical networks will be able to plug into for tactical communications. A key part of that effort involves ensuring space-based sensors can feed into the services' battlefield networks in near-real time. Once that transport layer is placed on orbit in 2022, the SDA wants to demonstrate space-based sensor data being downlinked to a ground station, then uplinked to the transport layer for dissemination to the tactical edge via TITAN and Link 16 tactical network. But ultimately, the SDA wants to cut out the ground station and move the data directly from the space-based sensor to the transport layer via optical cross links. That's a stretch goal for those first 10 satellites, and the minimal viable product when the second tranche of 150 satellites is added in 2024, said Tournear. Tournear declined to identify the SDA's mission partners on development of space-based sensors, which will need to use optical inter-satellite cross links to plug into the transport layer. https://www.c4isrnet.com/battlefield-tech/space/2020/05/06/how-low-earth-orbit-satellites-will-enable-jadc2/
