Watch the skies in 2022 for the first B-21 bomber flight

By:

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.

    Raytheon and Rafael to build Iron Dome in US

    By: Jen Judson WASHINGTON — American firm Raytheon Technologies and Israeli-based Rafael Advanced Defense Systems have formed a joint venture to build the Iron Dome missile defense system in the United States, the companies announced Aug. 3. Under the name Raytheon Rafael Area Protection Systems, the partnership is being set up to build a first-ever Iron Dome “all-up-round” facility stateside. The facility will build Iron Dome systems, the Tamir interceptor and launcher, and the SkyHunter missile (the U.S. version of Tamir), according to a Rafael-issued statement. Tamir and SkyHunter are capable of intercepting cruise missiles, unmanned aircraft, rockets, artillery, mortars and other threats. The partnership expects to finalize a site location before the end of the year, the statement said. “This will be the first Iron Dome all-up-round facility outside of Israel, and it will help the U.S. Department of Defense and allies across the globe obtain the system for defense of their service members and critical infrastructure,” Sam Deneke, vice president of Raytheon Missiles & Defense's land warfare and air defense business. Rafael and Raytheon have had a long partnership developing and manufacturing Iron Dome. The system is widely fielded in Israel and, according to Rafael, is “the world's most-used system with more than 2,500 operational intercepts and a success rate exceeding 90 percent.” The U.S. Army has chosen Iron Dome as an interim capability to counter cruise missiles while it continues to develop a future Indirect Fires Protection Capability, or IFPC, to counter those threats as well as enemy drones, rockets, artillery and mortars. Congress mandated the service buy two batteries to cover urgent cruise missile defense gaps, and another set of two if the Army didn't come up with a way forward for its enduring IFPC. While the Army has said it will not buy all-up Iron Dome systems as part of the IFPC program, officials developing the capability are looking at the possibility of incorporating parts of Iron Dome in the final solution. The Army plans to field Iron Dome by the end of the year, but it will still take time to train troops on the system before deployment. Some lawmakers are urging the Army to rapidly deploy the systems to the Middle East, arguing U.S. and coalition forces there need the protection from Iran and its proxies. In and analysis conducted by the Army, it was concluded the Iron Dome launcher and the Tamir interceptor's performances are “highly reliant” on their own battle management systems and multimission radars. The analysis also determined that the launcher and interceptor would be a viable option for an enduring IFPC solution as long as it worked on the Army's future Integrated Air-and-Missile Defense Battle Command System, or IBCS, which is under development, according to a report sent to Congress earlier this year. But Gen. Mike Murray, the head of Army Futures Command, which is in charge of the service's modernization efforts, testified before the House Armed Services Committee earlier this year that the Army has struggled to integrate Iron Dome into its IBCS system, mostly because the Israeli government has refused to provide critical source code needed for the integration. The Tamir interceptor's performance data proves its effectiveness when used within the Iron Dome system, but since data is lacking, it's uncertain how well it would perform when linked through IBCS to the Sentinel radar, which is used to alert air defense weapons of threats, the report noted. The service will conduct a shoot-off of best available options for integration into an enduring IFPC solution in the third quarter of fiscal 2021. The U.S. Marine Corps is also evaluating the system. https://www.defensenews.com/land/2020/08/03/raytheon-and-rafael-to-build-iron-dome-in-us/
