  B-21 Development Applying Tough Lessons From B-2

  By Lee Hudson PALMDALE, California— The U.S. Air Force is taking lessons learned from the plagued B-2 Spirit bomber development program and applying them to the next-generation B-21 Raider. While it is unknown when the B-2 will retire, the aging stealth bomber may end up flying alongside the B-21. The B-2 bomber flew its inaugural flight 30 years ago from the Plant 42 runway here. Today, the Northrop Grummansite is preparing for development of the Raider and two newly erected beige buildings have popped up, likely tied to the next-generation bomber. Although technical and acquisition problems inundated B-2 development, the classified B-21 is taking a different approach. Many details remain classified, but the company and service officials acknowledge the team is being run by the Rapid Capabilities Office instead of a traditional program office. B-21 development appears to be progressing; the Air Force's No. 2 officer—Air Force Vice Chief of Staff Gen. Stephen Wilson—has said first flight is slated for December 2021. But House Armed Services seapower and projection forces subcommittee Ranking Member Rep. Rob Wittman (R-Va.) alerted the public last year that there was a problem with the inlet design for the B-21's Pratt & Whitney-manufactured engines. Wittman says those issues were fully addressed and the program has made tremendous progress. “I've been pretty impressed by what both the Air Force and what Northrop Grumman have done in addressing these particular issues and I think we're on the right course,” he says. “Getting those things right to begin with and setting the tone and path I think is critically important.” An Air Force illustration issued in 2016 of the B-21 design suggests it may closely resemble the B-2. “The B-2 will be setting the path course for the B-21,” says Janis Pamiljans, aerospace systems sector president at Northrop Grumman. “What we've learned on B-2 are finding themselves baselined in the design for B-21 for supportability, sustainability, [and] mission capable rate.” The aging B-2s must be overhauled every nine years and are taken off the flight line for up to 12 months. Maintenance includes modifications and upgrades to antenna technology, avionics and software systems, costing U.S. taxpayers an average of $60 million for each aircraft, says Richard Sullivan, vice president and B-2 program manager at Northrop Grumman. Separately, the Air Force is funding the $3 billion B-2 Defensive Management System Modernization (DMS-M) program to enhance the aircraft's direct attack capability and upgrade its integrated air defense systems. The current DMS was designed in the 1980s and has not received any upgrades. “By leveraging ‘state-of-the-art' electronic warfare antennae, processors, controller and displays, B-2 aircrews will realize unprecedented situational battlespace awareness and dynamic, real-time threat avoidance in the most complex radio frequency emitter environments,” the Air Force says. “The inherent increased sensitivity of the modernized DMS over the legacy system, with increased processing power, will build a battlespace picture that could be shared with joint force platforms by onboard communication systems.” DMS-M is facing a possible eight-month delay as the service works with Northrop Grumman to implement an agile software development framework, Air Force acquisition executive Will Roper told lawmakers in March. Engineering and manufacturing development for the effort goes through July 2022, according to fiscal 2020 budget documents. Lawmakers acknowledge it is important that the nation's only operational stealth bomber remain relevant. But the House Armed Services Committee is concerned about DMS-M schedule delays, according to a report accompanying the lower chamber's mark of the fiscal 2020 defense policy bill. “Unless the B-2 DMS-M program makes significant changes, there may continue to be delays that will impact the success of the program,” the report says. The committee directs the Air Force to brief members on sufficient government software development expertise; contract definitization schedule; delivery schedule; determination of software baseline; and an assessment of related DMS-M-related program support. The Senate Armed Services Committee also is asking for answers regarding the U.S. bomber force. The upper chamber is requesting a brief on an updated bomber road map and plans for B-2 life cycle sustainment, among other items, according to a report accompanying the Senate's mark of the fiscal 2020 defense authorization bill. The upper chamber also would require details on Raider basing. To date, the service has been “real[ly] happy with the way Northrop has approached” the B-21 program, says Maj. Gen. James Dawkins, Eighth Air Force commander and overseer of the Joint-Global Strike Operations Center. The next-generation bomber completed a successful critical design review in December. “Everything I hear is that cost, schedule and performance is right on expectations,” Dawkins says. https://aviationweek.com/defense/b-21-development-applying-tough-lessons-b-2

  Germany walks away from $2.5 billion purchase of US Navy’s Triton spy drones

  By: Sebastian Sprenger COLOGNE, Germany — The German government has canceled plans to buy Northrop Grumman-made Triton drones to the tune of $2.5 billion, opting instead for manned planes carrying eavesdropping sensors. The decision to buy Bombardier Global 6000 aircraft comes after officials became convinced that the Global Hawk derivatives would be unable to meet the safety standards needed for flying through European airspace by 2025, a target date for Berlin's NATO obligations. A defense ministry spokeswoman told Defense News the Triton option had grown “significantly more expensive” compared with earlier planning assumptions. The U.S. State Department in April 2018 cleared Germany's request to purchase four MQ-4C Triton drones for signals intelligence missions under the country's PEGASUS program, short for “Persistent German Airborne Surveillance System.” The program includes a sensor, dubbed “ISIS-ZB” and made by Hensoldt, for intercepting communications and locating targets by their electromagnetic signature. The German Defence Ministry for years had been banking on the Triton purchase to come with a pre-installed safety-technology package that would be easily approved by European air traffic authorities. But officials saw their hopes dashed as Italy recently issued a military-type certificate for a sister drone — NATO's Alliance Ground Surveillance fleet of Global Hawks, stationed in Sigonella, Sicily — that prescribes tight restrictions on flights over the continent. Manned aircraft like the envisioned Global 6000 are allowed to routinely fly alongside civilian traffic, a prospect that the Germans see as more palatable than dealing with drone-specific airspace corridors. Berlin hopes to catch the tail end of Bombardier's Global 6000 manufacturing run, as the model is being phased out in favor of an upgrade. While that strategy could yield a better price, Berlin needs to move soon before the production line goes cold, according to officials. Letting drones fly in the same airspace as civilian traffic remains an unresolved problem, as the requisite sensing technology and the regulatory framework are still emerging. Germany previously tried filling its signals-intelligence gap with the Euro Hawk, but the project tanked in 2013 after spending $700 million because officials underestimated the trickiness of attaining airworthiness qualification. With the Triton gone, Germany's next ambition for a fully approved unmanned aircraft lies with the so-called Eurodrone, a cooperation with France. Officials have said that the program is designed from the start with manned-unmanned airspace integration in mind. https://www.defensenews.com/breaking-news/2020/01/28/germany-walks-away-from-25-billion-purchase-of-us-navys-triton-spy-drones
