Pratt & Whitney’s Engine Powers New B-21

Connecticut Post reports that the B-21 “is the Air Force’s first new bomber since the 1989 debut of the B-2 Spirit stealth bomber, with both using a ‘flying wing’ design to reduce the odds of showing up on radar, which uses four engines from GE Aviation.” The Air Force “has yet to specify how many engines will power the B-21.” Military trade publications “have cited analyst speculation that the B-21 engine may be a variant of the F135 engine Pratt & Whitney makes for the Lockheed Martin F-35 Lightning II fighter jet.” Pratt & Whitney recently “completed its 1,000th engine under the F135 program.” Raytheon CEO Greg Hayes said, “The F135 … is the safest, most capable and best-value, military jet engine in operation. We’re working on the F135 engine core upgrade. … This will allow the F135 to provide even more thrust, range and electrification to the aircraft.”

B-21 Raider Flies Test Sortie from Edwards Air Force Base

Aviation Week reports that a “Northrop Grumman B-21 Raider flew a test sortie from Edwards AFB, California, on Jan. 17, notching the second acknowledged flight of the second-generation stealth bomber.” Defense News reports US Air Force spokeswoman Ann Stefanek said, “Flight testing is a critical step in the test campaign managed by the Air Force Test Center and 412th Test Wing’s B-21 combined test force to provide survivable, long-range, penetrating strike capabilities to deter aggression and strategic attacks against the United States, allies and partners.” According to Defense News, “Northrop Grumman has built or is in the process of building at least six test B-21s, including this first bomber. The B-21 program is now in the engineering and manufacturing development phase, and the test aircraft are production-representative platforms, meaning they are being built on the same line with the same tools, technicians and processes as production bombers. Ellsworth Air Force Base in South Dakota is to be the first base to receive a Raider, scheduled for delivery in the mid-2020s.”

B-21 Raider Undergoing Flight Testing

Defense News reported that the “B-21 Raider took to the air for the first time in November, nearly a year after its public debut in California. In 2024, the U.S. Air Force’s next stealth bomber could take even greater steps.” The first B-21 Raider “flew to Edwards Air Force Base on Nov. 10. It is now undergoing flight testing, which also includes ground tests and taxiing.” The USAF has “confirmed at least six B-21s are in various stages of construction by Northrop Grumman or are undergoing tests. The program is now in the engineering and manufacturing development phase, the service said in November, and Ellsworth Air Force Base in South Dakota is expected to receive its first Raider in the mid-2020s. The service plans to buy at least 100 B-21s, an advanced stealth bomber, to replace the aging B-1B Lancer and B-2 Spirit bombers. It will provide the service with new abilities to conduct penetrating deep-strike missions, and the aircraft will be able to carry both conventional and nuclear weapons.”

Final Antares 230+ Rocket Lifts Off to Resupply ISS

Spaceflight Insider reports that in near-perfect weather, the final Antares 230+ rocket “took to the skies to send the Cygnus cargo spacecraft on its way to the International Space Station.” Carrying the autonomous NG-19 Cygnus resupply freighter, dubbed the S.S. Laurel Clark, the Antares rocket successfully “launched at 8:31 p.m. EDT Aug. 1 (00:31 UTC Aug. 2), 2023, from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.” It flawlessly lifted off “from its launchpad, drawing a bright arc of light against the fading evening sunset, marking the start of another critical cargo run to the ISS.” Some 8,200 pounds (3,700 kilograms) of supplies, hardware and experiments “are aboard NG-19. It is expected to arrive at the ISS on the morning of Aug. 4 where it will be captured by the outpost’s robotic arm and attached to the Earth-facing port of the Unity module.” Over the coming weeks, members of the station’s Expedition 69 crew “will work to unload the cargo before beginning to reload it with trash.” After about two months, Cygnus “is expected to depart the ISS for an eventual destructive reentry over the Pacific Ocean.”
