The stealth strike bomber was unveiled in December 2022 and officially moved into low-rate production earlier this year. In January, Northrop Grumman said six B-21 bombers are in various stages of final assembly and testing at its facility in Palmdale, California.

On Wednesday, the Air Force released a new image of the aircraft it calls the “backbone of the  U.S. Air Force bomber fleet.”

Northrop Grumman on Thursday released an additional image of the bomber in flight, saying the test campaign at Edwards AFB was led by a Combined Test Force (CTF) composed of personnel representing the Air Force and the manufacturer.

“CTF test pilots indicate the jet is performing as expected with the aircraft flying like the simulator, reflecting the precision of the digital environment on B-21,” Northrop Grumman said in a statement.

Andrew Hunter, assistant secretary of the Air Force for acquisition, technology and logistics, addressed the Senate Armed Services Committee earlier this month on the B-21’s progress.

“We are in the flight test program, [and] the flight test program is proceeding well,” said Hunter. “It is doing what flight test programs are designed to do, which is helping us learn about the unique characteristics of this platform, but in a very effective way.” 

Designed to carry out long-range conventional and nuclear missions, the B-21 is set to eventually replace aging B-1 Lancer and B-2 Spirit fleets. The B-21 is scheduled to hit full operational status in the mid-2020s.

Since 2020, the U.S. Air Force has had a program called Agility Prime to look at electric aviation’s potential uses, but now legislators want the effort to be ramped up. As part of the 2025 National Defense Authorization Act, the bill would “set up a working group made up of top-ranking defense officials” to kick-start Agility Prime, and it’s throwing some major brass at it.

The new committee, if approved, would be run by the Secretary of the Air Force and would include the Army and Navy secretaries and the chairman of the Joint Chiefs of Staff. The Air Force Secretary would have to submit a first report by September 2025 and annually until 2027.

The Air Force already has contracts with several companies developing eVTOLs, including Beta Technologies, which delivered a test article of its Alia aircraft to Florida’s Eglin Air Force Base, where it did its first test flight in November.

The incident occurred Monday at the 82nd Training Wing at Sheppard Air Force Base in Texas, but the pilot was attached to the Euro-NATO Joint Jet Pilot Training Program that instructs new military pilots from Canada and various European countries.

The pilot was taken to a hospital but died about 12 hours after the incident, which the Air Force is currently investigating.

There have been issues with the ejection seats in Texan IIs, which have been in service for 17 years and are based on the Pilatus PC-9 built under license by Beechcraft. The airplanes were grounded in 2022 after a potential defect was discovered in the Martin-Baker seats’ explosive cartridge, and some were replaced.

It fulfilled primary trainer duties for more than 20 years and was modified to serve as a light ground attack aircraft in the form of the A-37 Dragonfly. However, as the 1980s approached, so did the end of the T-37’s projected life cycle, and military leaders determined a more modern replacement was needed.

Among the items on the Air Force’s wish list were cabin pressurization, increased range, lower fuel consumption, increased power, and updated avionics. In 1981, a request for proposal (RFP) was issued for a replacement. Several companies responded, but ultimately, Fairchild was chosen, and its proposed aircraft was given the designation T-46.

Compared to the T-37, the T-46 was nearly identical in external dimensions with similar empty and maximum weights. The most significant visual differences were the T-46’s high wing and the “H” tail, with twin vertical stabilizers mounted to the ends of the horizontal stabilizer that strongly resembled those of the company’s previous jet, the A-10 Thunderbolt II.

The selection of twin vertical stabilizers for the T-46 is an interesting one. Historically, this tail configuration was intended to provide a clear area for jet exhaust, add redundancy to aircraft anticipated to sustain battle damage, or increase yaw authority by placing the rudders within the prop wash of wing-mounted engines. None of these concerns applied to the T-46, and one wonders whether Fairchild simply aimed to save money by repurposing its former engineering efforts in the A-10 program for its new aircraft.

Before any conforming examples took flight, Fairchild contracted with a third party to fabricate a smaller, 62 percent scale proof of concept. The concept, called the Model 73 NGT, was then flown by Burt Rutan’s company in Mojave, California, for the initial test flights. The NGT served its purpose and is on display at the Cradle of Aviation Museum on Long Island, New York.

When the initial, full-scale T-46 prototypes took flight, a number of problems arose. As outlined in a U.S. General Accounting Office (GAO) report, the aircraft’s drag was too high, it did not provide adequate stall warning, the primary flight controls had trim problems that affected stability, and the speedbrakes created unacceptable buffet levels. Additionally, the T-46’s weight ballooned to a figure of 900 pounds higher than projected. 

While the Air Force observed that many of these problems were common among new types and could likely be remedied, Fairchild was also found to be struggling with cost, schedule, and contract difficulties. At least one source suggested that the rising development costs of the Saab-Fairchild SF340 commuter turboprop were eating into Fairchild’s budget for other projects and stretching its resources thin. 

In March 1987, with three prototypes flying and 10 additional examples in various stages of assembly and some 17 months after the first flight, the T-46 program was canceled. Most attribute the decision to a combination of the aforementioned internal struggles at Fairchild as well as a strong motivation for the U.S. Congress to cut costs across the board.

For an aircraft type that generally showed promise, it was unfortunate. The T-46 stood to follow in the T-37’s footsteps, with potential armed export versions on the horizon that could have kept Fairchild in business for many years. In theory, the company could have even modified the cabin to accommodate passengers, as Cessna did with its full-scale mock-up of the model 407.

Today, all three T-46 prototypes survive. One is in storage at the Pima Air & Space Museum in Arizona, one is on display at the Air Force Flight Test Museum at Edwards Air Force Base in California, and one is undergoing restoration at the National Museum of the United States Air Force in Dayton, Ohio.

The single-seat F-16 assigned to the 49th Wing based at Holloman AFB went down around 11:50 a.m. MDT, according to the Air Force.

The crash occurred near White Sands National Park about 7 miles from the base, near the U.S. Army’s White Sands Missile Range.

According to a report in Air Force Times, Holloman is a training hub for F-16 pilots, graduating an average of 180 candidates per year. Tuesday’s crash marks the fourth involving Air Force F-16s within the past 12 months, with the other three occurring in South Korea.

The news source cited an average of three F-16 losses per year over the past 10 years. The service operates 841 Fighting Falcons, with plans to reduce that to 830 during fiscal year 2025, according to the report.

This year marks the first time in the annual Reno aviation event’s history that air racing will not be featured. In September, the last Reno Air Race took place at KRTS, as community leaders had determined that encroachment by homes and other non-race entities were creating too much of a risk. The last races of that event were canceled after two pilots died in a midair collision.

RARA is reviewing proposals from six cities interested in hosting the National Championship Air Races next year. The organization expects to announce the new location later this spring.

“The aircraft will play a crucial role in a variety of missions, including intercontinental ballistic missile (ICBM) security operations, search and rescue efforts, and personnel transport,” the Air Force said.

The Air Force, which initially planned to order 80 MH-139s, has reduced its projected buy to 42, Air and Space Forces Magazine recently reported. Malmstrom AFB is one of three ICBM bases where the helicopter will be stationed. Malmstrom, F.E. Warren AFB, Wyoming, and Minot AFB, North Dakota, will each receive 11 of the aircraft.

Joby Aviation, a manufacturer of eVTOL air taxis that it expects to begin operating in 2025, on Tuesday committed to deliver two aircraft to MacDill Air Force Base (KMCF) in Tampa, Florida, to be used for Air Force training and testing. The agreement is an expansion of the company’s $131 million contract with AFWERX, the innovation arm of the Air Force, which calls for the delivery of nine aircraft.

In total, Joby’s completed and current work with the U.S. Department of Defense represents a contract value of $163 million: a figure the firm claims is the largest in the eVTOL industry. Competitors Archer Aviation and Beta Technologies, among others, also own contracts with AFWERX.

MacDill Air Force Base is home to the U.S. Special Operations Command, U.S. Central Command, and several Air Mobility Command and logistics-focused units within the military. Air Force personnel will test and train with Joby’s aircraft on the base and in the surrounding area.

“The early investment and vision by the U.S. government in this critical technology is proving foundational as we continue our path toward commercial passenger service,” said JoeBen Bevirt, founder and CEO of Joby. “This work will provide Joby with valuable early operational experience, while providing the U.S. Air Force with firsthand understanding of the performance of our aircraft and its potential applications.”

Joby’s electric air taxi is designed to carry a pilot and up to four passengers, with a range of about 100 sm (87 nm) and cruise speed of 200 mph (174 knots). It produces zero operating emissions and a fraction of the noise of helicopters, according to the manufacturer.

Through AFWERX, the Air Force is able to experiment with aircraft such as Joby’s without spending billions on development and production. The manufacturers of those vehicles, meanwhile, receive a funding boost and take to the skies before obtaining FAA type certification. These early flights may provide critical data points to inform Joby as it refines its design, particularly when it comes to the experience of pilots.

“The Agility Prime team is very excited to progress through a novel acquisition approach,” said Lieutenant Colonel John Tekell, branch chief of Agility Prime, a division within AFWERX focused on vertical lift technologies. “These two aircraft at MacDill AFB allow the program to take the next steps in learning to maximize the operational opportunity of eVTOLs.”

For the first time, Joby at MacDill will work directly with DOD operational units. Personnel will use the aircraft to conduct logistics missions and test use cases in personnel transport, casualty evacuation, and support of security forces.

Joby in September delivered the first of nine eVTOL air taxis to the Air Force ahead of schedule, shipping it to Edwards Air Force Base in California. With one additional aircraft expected to be delivered to Edwards this year and two scheduled to be shipped to MacDill, the company has now committed a total of four aircraft to the department.

Air Force experimentation at Edwards is expected to inform the future test campaign at MacDill. In addition, Air Force, Marine Corps, and Army aviators, ground crews, and program managers have visited Joby’s flight test facility in Marina, California, for ongoing flight training. 

Personnel are further exploring potential logistics, medical, and personnel transport applications for the aircraft. According to Joby, initial evaluations have proven the model’s high speed, low noise, and minimal maintenance and operating costs make it suitable for a wide variety of use cases.

Continued evaluations and pilot training will allow Joby’s air taxi to log critical flight hours before it enters commercial service, accelerating its development and, in theory, improving safety.

Recently, the manufacturer completed a key step toward that commercial rollout. The FAA in February approved Joby’s certification plans for various aircraft components such as structural, mechanical, and electrical systems, part of the company’s type certification process. The next phase involves submitting a curriculum to be used in for-credit FAA evaluations of the aircraft, which will most likely happen at the end of this year or the start of next.

If Joby can pass that test, it will move to the final steps. Type certification could follow soon after.

Joby is not the only eVTOL manufacturer relying on AFWERX to give it a lift throughout the process.

Competitor Archer, for example, has its own $142 million contract with AFWERX, under which it expects to deliver up to six aircraft to an Air Force base yet to be determined. Both Archer and Joby received $1 million in early payments from the department last year, representing each company’s first revenue.

Another competitor, Beta, in January wrapped up its first electric aircraft deployment for the Air Force at Eglin Air Force Base’s Duke Field (KEGI) in Florida.

In addition to working with private firms, AFWERX is collaborating with the FAA to share eVTOL testing capabilities and data. Another partnership with NASA aims to develop a nationwide digital operations center for air taxi services, which would help manage eVTOL traffic.

The interplay between manufacturers and these government partners will be interesting to watch as the FAA steers the U.S. toward the goals outlined in its Innovate28 blueprint. The document, while holding no legal standing, outlines the agency’s approach to air taxi services in the short term, culminating in scaled operations in time for the 2028 Olympic Games in Los Angeles.

“Today, [former Air Force] general Tom Stafford went to the eternal heavens, which he so courageously explored as a Gemini and Apollo astronaut as well as a peacemaker in Apollo Soyuz,” NASA Administrator Bill Nelson said on X, formerly known as Twitter. “Those of us privileged to know him are very sad but grateful we knew a giant.”

Stafford was born in Weatherford,  Oklahoma, in 1930 during the so-called “golden age of aviation.” Enamored with flight from childhood, he wanted to fly airplanes and later announced ambitions to be a fighter pilot. Going into space, he told journalists later in life, was the next logical step.

Military Career

In high school, Stafford served in the Oklahoma National Guard in a nonaviation role. He was athletic and earned a football scholarship to the U.S. Naval Academy, although he did not play in college due to a career-ending injury sustained during practice. After graduation in 1952, he entered the Air Force, training to be a pilot. Eventually he would fly a F-86 Sabre jet, and subsequently became a test pilot.  He flew more than 120 types of aircraft during his career.

Space Career

In 1962, Stafford was selected for astronaut training and flew aboard Gemini 6 in 1965 and Gemini 9 in 1’66. In ’69, he was named commander for Apollo 10, which was the second crewed mission that orbited the moon. Accompanied by Gene Cernan, they became the first crew to fly the Apollo Lunar Module in lunar orbit.

In the 1970s Stafford, now a brigadier general, was named commander of the Apollo-Soyuz Test Project, the first joint U.S.-Soviet space mission. Preparation included traveling to Moscow to learn Russian. The 1975 rendezvous between the Soyuz capsule and the Apollo spacecraft was commemorated by a photograph of Stafford shaking hands with cosmonaut Alexei Leonov.

Stafford flew three types of spacecraft for NASA and logged more than 500 hours of space flight.

After the Apollo-Soyuz mission, Stafford resigned from NASA and returned to the Air Force, where he became the commanding general of Edwards Air Force Base, California, and oversaw the development of new aircraft and pilot training. His expertise was also in demand during the development of NASA’s space shuttle program. 

According to information from the Stafford Air & Space Museum in Weatherford, Stafford also served as the commanding general of Area 51, the common name for the top-secret military facility that may or may not be in the Nevada desert.

Founded in 1993, the Stafford Air & Space Museum is a Smithsonian affiliate. Among the exhibits are test-fired engines used during the development of the U.S. space program. The museum is also the home of the Gemini 6 spacecraft that Stafford and astronaut Wally Schirra flew in a rendezvous with Gemini 7.

The Air Force, Navy, and Marine Corps all grounded their tiltrotor fleets December 6 amid an investigation into what caused a crash of an Air Force CV-22 Osprey off the coast of Japan that killed the crew of eight airmen.

Returning the aircraft to service is critical to national defense, officials said.

“Effective March 8, 2024, at 7 a.m. EST, Naval Air Systems Command (NAVAIR) is issuing a flight clearance for the V-22 Osprey, thereby lifting the grounding,” NAVAIR said in a statement. “This decision follows a meticulous and data-driven approach prioritizing the safety of our aircrews.”

Last month, U.S. Air Force Special Operations Command (AFSOC) said that, while it was known that a materiel failure caused the crash, the cause of that failure has not yet been determined.

• READ MORE: Air Force, Navy Ground V-22 Fleets Amid Crash Probe

In a statement Friday, NAVAIR said it had partnered with the Air Force investigation to identify the materiel failure. “Maintenance and procedural changes have been implemented to address the materiel failure that allow for a safe return to flight,” NAVAIR said.

The Marine Corps has returned MV-22s to flight following the Naval Air Systems Command’s announcement that deemed the aircraft safe to fly, and will now execute a deliberate, three-phase plan to return all MV-22 squadrons to full capability.

Following NAVAIR’s bulletin announcing the aircraft’s flight clearance, AFSOC said it was implementing a “multi-phased approach” to returning its fleet back to service.

• READ MORE: Crash Prompts Japan to Call on U.S. Military to Ground Ospreys 

“Phase one of AFSOC’s return to fly plan includes ground and simulator training, integrating planned flight controls, safety briefings, a review of maintenance records, and refining by-squadron training plans to implement the new safety protocols,” the command said in a statement. 

In the second phase, aircrew and maintainers will go through a “multi-month program” focused on aircraft mission currency and proficiency, AFSOC said.

“While maintainers have remained engaged, conducting maintenance necessary to sustain the CV-22 during the stand-down, they will receive training in line with the maintenance protocols directed by the NAVAIR return to fly bulletin,” AFSOC said. “Each squadron will progress through this phase at different speeds based on a variety of factors including maintenance requirements for aircraft, experience level of personnel in the squadron, and weather impact to flight schedules.”

 Once that is complete, the aircraft will resume full missions in a third phase.

“This phased approach affords AFSOC the time required to maximize opportunities to learn as much as possible from the Safety Investigation Board and Accident Investigation Board to mitigate risk to our aircrew, maintainers, and joint partners,” AFSOC said.
