USAF Picks B-21 For Software Learning Demo Challenge
The U.S. Air Force has selected the Northrop Grumman B-21 to demonstrate a potentially revolutionary approach to flightworthy software.
The future stealth bomber will demonstrate a software architecture running the operational flight program (OFP) that learns and adapts as it flies a mission, says Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics.
Such an approach potentially “allows them to land with better code than they took off with,” Roper tells Aerospace DAILY. The architecture enables the code to update itself during a mission.
Asked if the demonstration involves software code in the OFP, the operating system of a military aircraft, Roper replied affirmatively: “Within the OFP. That kind of adaptability is what we want to aspire to.”
As a special access program, details of the B-21's schedule, capabilities and even cost are kept secret. But Roper says he is able to discuss what he calls the “digital bullet challenge,” albeit within strict limits. Asked if the B-21 software demonstrations imply the insertion of a deep learning technique known as a neural network, Roper declined to answer.
“Details of how I won't go into,” Roper says. “But B-21 is trying to not just do agile software. They want to blaze new territory, a new trail for the Air Force. The idea that one of our most complicated airplanes with one of the most challenging missions is also taking on one of the most challenging software approaches to make their software living [and] breathing on the plane itself is inspiring.
“They're going to be pushing the boundaries of how aircraft software should work in this century, and increasingly the software is where the cutting edge—the winning edge—is going to come from,” he explained.
Roper's description appears to push the boundaries of software used in the flight computers of a commercial or military aircraft. Aircraft certification standards demand a highly rigid approach to software architecture, with the function of each line of code validated and verified on the ground before it is allowed to be used in flight. The challenge set for the B-21 could lead to altering or even adding software lines of code in the OFP during a flight.
The Air Force launched the B-21 program in 2015 by awarding a $21.4 billion contract to Northrop. Air Force officials have previously announced that first flight is scheduled around December 2021. The aircraft will take off from Northrop's final assembly center in Palmdale, California, and fly to the flight test center on the adjoining Edwards Air Force Base.

Lockheed dives into next-generation missile defense interceptor competition
By: Jen Judson WASHINGTON — Lockheed Martin said it will compete to build the Missile Defense Agency's Next-Generation Interceptor designed to protect the homeland against intercontinental ballistic missile threats from North Korea and Iran. The company is “excited to confirm that we are putting in a bid for the Next-Generation Interceptor,” Sarah Reeves, Lockheed's vice president of missile defense programs, told reporters Aug. 3. Bids were due July 31. Boeing and a Raytheon-Northrop Grumman team have already announced their intentions to compete to develop and field the agency's new interceptor following the cancellation of the Redesigned Kill Vehicle meant to replace the warhead on the current Ground-Based Interceptors. Those missiles are part of the Ground-based Midcourse Defense System, which is operational at Fort Greely, Alaska, and Vandenberg Air Force Base, California. The RKV program was paused in May 2019 and then abruptly terminated in August 2019 due to insurmountable technical issues resulting in delayed schedules and cost increases. The Defense Department announced at the time that it would embark on an entirely new program to field a future interceptor. MDA now plans to downselect to two companies, which will then compete for the right to build the interceptor. While MDA struggled with RKV, Lockheed invested the last two decades on multi-kill vehicle technology,” Reeves said. Lockheed had one of three small contracts to design a kill vehicle that could take out multiple warheads several years ago that would lead to a program that would replace the RKV called the Multi-Object Kill Vehicle (MOKV) program. Raytheon and Boeing had won the remaining two contracts. Reeves stressed the need for the new interceptor to be able to go after threats that disperse multiple objects including decoys. “We are looking carefully at the lessons learned from RKV including parts survivability testing which, in that program, was done too late and caused a major system redesign, as well as ensuring early-and-often testing and fly-before-you-buy mentality,” Reeves said. Lockheed plans to conduct two successful flight tests before going into production, Reeves said, which as an MDA program requirement. “The time is right now,” Reeves said. “We have significant investments and the technology a couple of decades ago, when this was initially a vision of MDA, wasn't quite there, but now it is ready to go.” The company plans to take elements from its existing capabilities such as the Terminal High Altitude Area Defense (THAAD) system, which Reeves said has had a 100 percent mission success rate, and the Aegis missile defense system. Lockheed also will garner experience from its partnership with the U.S. Navy on its Trident II submarine-launched ballistic missile system, which “has to survive these more hostile environments,” she said. And Lockheed's experience with space is another asset that will contribute to understanding technology needed for an NGI, which will need to travel through space, according to Reeves. Lockheed is also optimistic, Reeves said, that it can meet a faster schedule for NGI than currently planned. Some Defense Department officials said NGI could not be fielded until the 2030s but the MDA director and U.S. Northern Command's commander believe it is possible to move that timeline to at least 2028 or earlier. The company plans to use tools such as artificial intelligence, machine-to-machine learning, big data analytics and 3-D printing to “accelerate the schedule and to deliver products faster than we have had in the past,” Reeves said. https://www.defensenews.com/industry/2020/08/03/lockheed-dives-into-next-generation-missile-defense-interceptor-competition
