WASHINGTON — Sorry, aviation geeks: The first flight of the U.S. Air Force's latest stealth bomber won't be happening this year.
The Air Force had once projected the first flight of the Northrop Grumman B-21 Raider would occur in December 2021, but the new bomber will not be ready to roll out until early next year for a flight in mid-2022, said the Air Force Rapid Capabilities Office director, Randall Walden, according to a Jan. 15 story in Air Force Magazine. The RCO manages the B-21 program on behalf of the service.
Two B-21s are under construction at Northrop Grumman's production facility in Palmdale, California. The first aircraft hasn't made it to final assembly yet but is “really starting to look like a bomber,” Walden told Air Force Magazine.
“The second one is really more about structures, and the overall structural capability,” Walden said. “We'll go in and bend it, we'll test it to its limits, make sure that the design and the manufacturing and the production line make sense.”
Although information about the B-21 is notoriously limited, with many details of the Raider's cost, appearance and capability classified, Walden offered a couple optimistic notes about the program's progress.
For one, production of the B-21 is already becoming more efficient during the build of the second aircraft, he said. Northrop Grumman is using a business jet as a test bed for new avionics and software, allowing those systems to be debugged before they are installed in the B-21 aircraft.
While there have been some disruptions to the supply chain due to the COVID-19 pandemic, Walden said the program has worked with companies to mitigate changes to the production schedule.
“In the last few months, we did another successful end-to-end demonstration to further mature that hardware and software, and it's working quite well,” Walden said. “We're preparing ourselves not just for first flight, but ultimately the subsystem testing that will be required during those flight test phases.”
The Air Force has committed to buying at least 100 B-21s, although officials such as Gen. Timothy Ray, who leads Air Force Global Strike Command, said more will be needed to meet the service's future bomber requirements, which could be in excess of 220 aircraft.
The service is expected to make a final decision this year on which bomber installations will first host the Raider. In March 2019, the Air Force picked Ellsworth Air Force Base in South Dakota as its preferred location, with Dyess AFB in Texas as an alternate location.
A virtual industry day was held Jan. 11 to provide information on contract opportunities for construction projects needed to support B-21 operations. Those facilities could include a “low-observable restoration facility, a wash rack and general maintenance hangar, and a mission operations planning facility,” according to the Air Force.
The service expects to begin fielding the B-21 in the mid-2020s.

Andrew Eversden WASHINGTON — The U.S. Department of Defense announced $600 million in contracts for 5G experiments Thursday evening for projects at five military bases across the country. The long-anticipated awards are for a series of 5G experiments, including smart warehouses, advanced radars, and augmented and virtual reality capabilities. The awards are part of a Pentagon effort to work with commercial vendors to advance the 5G capabilities of both the department and industry. “The Department of Defense is at the forefront of cutting edge 5G testing and experimentation, which will strengthen our Nation's warfighting capabilities as well as U.S. economic competitiveness in this critical field," said Michael Kratsios, acting under secretary of defense for research and engineering, in a statement. “Through these test sites, the Department is leveraging its unique authorities to pursue bold innovation at a scale and scope unmatched anywhere else in the world. Importantly, today's announcement demonstrates the Department's commitment to exploring the vast potential applications and dual-use opportunities that can be built upon next-generation networks.” The DoD is setting up test beds at several bases where military leaders, industry and academia will work together on a broad range of experiments. The test beds are Hill Air Force Base, Utah; Joint Base Lewis-McChord, Washington; Marine Corps Logistics Base Albany, Georgia; Naval Base San Diego, California; and Nellis Air Force Base, Las Vegas, Nevada. According to Joseph Evans, the DoD's director of 5G, the department plans for the testbeds to be working in a year. “Each of the experiments has some aspect that's really new and exciting to us,” Evans told reporters. “In addition, it also provides an opportunity for industry to experiment and mature their technologies along those parallel tracks.” According to a DoD press release, the bases were chosen because of their access to spectrum, and mature fiber and wireless infrastructure. At Joint Base Lewis-McChord, the Pentagon will work with four vendors to experiment with 5G-enabled augmented and virtual reality goggles for mission planning, training and operations using mid-band spectrum. The vendors are GBL System Corp., AT&T, Oceus Networks and Booz Allen Hamilton. Evans told reporters that in year three of the work at the base the department wants a “brigade-sized deployment of the technology.” The department will also address 5G spectrum sharing challenges with cellular networks through an experiment at Hill Air Force Base. The project, according to a DoD press release, will “develop sharing/coexistence system prototypes and evaluate their effectiveness with real-world, at-scale networks in controlled environments.” The department is seeking to allow sharing or coexistence between airborne radar systems and 5G cellular technology in the 3.1-3.45 GHz band. Vendors for the spectrum sharing test bed include Nokia, General Dynamics Mission Systems, Booz Allen Hamilton, Key Bridge Wireless, Shared Spectrum Company and Ericsson. The Defense Department is also partnering with AT&T at Nellis Air Force Base for a distributed command and control testbed to enhance C2 survivability in combat. The telecom giant will eventually provide a mobile 5G environment with high capacity, low latency communications to meet the needs of a mobile combined air operations center. “We're basically trying to make our forces more survivable by taking command and control functions that have long been housed in single buildings and spread them out and make them make them mobile,” Evans told reporters. “So [we're] really trying to change the way our forces are deployed in the field.” The department will experiment with 5G-enabled smart warehouses at both Naval Base San Diego (NBSD) and Marine Corps Logistics Base Albany, Ga. The project in San Diego will focus on transshipment between shore facilities and naval units, while the Marines Corps project will center on vehicle storage and maintenance. Both projects will work “to increase the efficiency and fidelity of ... operations, including identification, recording, organization, storage, retrieval, and transportation of materiel and supplies,” a DoD press release said. Industry partners for the San Diego-based project are AT&T, GE Research, Vectrus Mission Solutions Corporation and Deloitte. AT&T will use cullar spectrum in the sub-6 GHz and millimeter wave bands, the DoD press release said. Partners at Marine Corps Logistics Base Albany, Ga. are Federated Wireless, GE Research, KPMG and Scientific Research Corporation. The Air Force also recently chose AT&T to provide 5G capabilities at three bases. The DoD is also in the process of choosing vendors for 5G experiments at seven more bases. According to Evans, the first solicitation release and industry day for the Navy and Marines Corps bases in that tranche will come in mid-October using the Navy's Information Warfare Research Project consortium. The Air Force and Army solicitations are expected to be rolled out through December through the National Spectrum Consortium, Evans said. https://www.c4isrnet.com/battlefield-tech/it-networks/5g/2020/10/08/pentagon-announced-600-million-in-5g-experimentation-contracts/
