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.

By: Joe Gould WASHINGTON ― Four defense industry trade associations “strongly oppose" a handful of Pentagon-backed procurement reform proposals that they say would harm the defense industrial base, and they're asking Congress to reject them. Two of the proposals aim at controversial pricing practices used by TransDigm by requiring contractors to submit cost information for commercial items and by requiring contracting officers to conduct a commercial item determination for every procurement. Others would set a preference for performance-based contract payments and authorize the Defense Department to release or disclose detailed manufacturing or process data. The May 6 protest letter came from the Acquisition Reform Working Group — made up of the National Defense Industrial Association, American Council of Engineering Companies, the Computing Technology Industry Association and the Information Technology Industry Council — to the the House and Senate armed services committees. It comes as the panels were readying their drafts of the 2021 National Defense Authorization Act. The Pentagon has worked to monitor its network of suppliers from the economic shocks associated with the coronavirus pandemic and to protect suppliers by using emergency funding from Congress to speed payments and improve cash flow along the supply chain. The trade groups noted they represent “thousands of small, mid-sized, and large companies in addition to hundreds of thousands of employees that provide goods, services, and personnel to the Department of Defense,” and said the four proposals a “could have significant consequences for the defense industrial base.” Congress focused ire at TransDigm last year after the Defense Department's Inspector General found for $26.2 million in parts the military bought from TransDigm, it earned $16.1 million in excess profit. Transdigm was the only manufacturer of the majority of the parts, which let it set the market prices even for competitively awarded parts. Though DoD has argued its contractors need new latitude to make commercial item determinations and obtain cost or pricing information to prevent the excessive pricing TransDigm was accused of, the trade groups argue the TransDigm's actions weren't facilitated by an inappropriate reliance on improper commercial item determinations, or insufficient access to pricing data. “As illustrated by the TransDigm Group, Inc's pricing practices, generally once a conversion to a commercial product or commercial service is made, it is common for prices to increase and subsequent contracting officers find it difficult to obtain data necessary to determine price reasonableness and negotiate fair and reasonable prices on behalf of the taxpayer,” the department said in its proposal. Another proposal would require a contractor to submit uncertified cost information for commercial item proposals or contracts less than $2 million. The idea behind the reform is DoD wants to be able to get more insight into the costs of sole-source items and put itself in a more favorable position to negotiate with sole-source companies. Congressional hearings on TransDigm's excessive pricing showed Defense leaders need the authority to obtain the data “to the extent necessary to determine price reasonableness is paramount in ensuring that such excessive pricing practices are curtailed.” But the trade groups argue that levying the new regulations would “add a significant barrier to commercial item acquisition, reduce information sharing, further burden the system, and impede—rather than enable—the delivery of capabilities to the warfighter at the ‘speed of relevance'—all with little to no added protection for the government or the taxpayer." The trade associations also opposed DoD's legislation to set a preference for performance-based contract payments. The groups said a DoD proposal to “recouple” total performance-based payments to total cost incurred would reverse Congress's previous work to emphasize performance over cost and contradict a spate of defense acquisitions rules. DoD's argument is that it shouldn't be reimbursing a contractor more than its actual costs, or it “would result in negative levels of contractor investment,” and create a disincentive for contractors to deliver. Another disputed proposal would let DoD release detailed manufacturing or process data, or DPMD, pertaining to privately funded commercial or noncommercial items outside of the government to third parties seeking to compete against the original equipment manufacturer. It's the latest episode in a running game of tug-of-war between industry and DoD over intellectual property. While Congress has in recent years prodded DoD to set intellectual property strategies early in acquisition programs and negotiate for IP rights on a case-by-case basis, the trade groups argue the proposal would give DoD “an automatic default authority” and “eliminate the possibility of a negotiated solution.” https://www.defensenews.com/congress/2020/05/15/citing-transdigm-dod-seeks-new-acquisition-powers-and-trade-groups-oppose/
