To keep 60-year-old bombers in the air, the US Air Force is now having daily briefings over its ever-diminishing parts supply. The North Star Readiness Campaign was launched by Air Force Global Strike Command in collaboration with Air Force Materiel Command and the Defense Logistics Agency. The goal is to increase the number of combat capable Boeing B-52 Stratofortress and Rockwell B-1 Lancer bombers right now.
The military announced this campaign just days after the tragic B-52 crash at Edwards Air Force Base that killed all eight people on board. Although the mishap is still under investigation, the extreme age of the airframes makes them highly susceptible to mechanical and system malfunction. In part as an effort to prevent any future crashes, the North Star initiative is accelerating the delivery of parts that were previously taking a week or longer to now be completed in two or three days.
Meanwhile, the sixth-generation Northrop Grumman B-21 Raider is meant to eventually replace these aging bombers. Yet, it is still years away from being fully operational. This new campaign raises a serious question for the military about the true viability of its increasingly antiquated fleet. Many wonder if fixing the supply chain is enough to reverse a major decline in bomber readiness that has been getting worse for years.
The Air Force's statistics indicate that in fiscal year 2024, the B-52's mission-capable percentage dropped to 54%. From 59% in 2022 and over 66% in 2020, this represents a consistent decline. Even worse was the B-1 bomber, whose readiness rate fell from 55% in 2022 to just 43% in 2024.
The North Star campaign brings together leaders from the maintenance office and the flight line to coordinate their efforts as efficiently as possible. The USAF says this team has reduced mission-impacting part faults from over 450 to about 160 since it began. According to Lieutenant General Linda Hurry:
“Our constant engagement with Global Strike leadership and joint logisticians has helped us reinvigorate the supply chain and return these airframes to the fleet faster after depot maintenance, increasing bomber capacity and capability. It is a privilege to support the dedicated maintainers who work tirelessly to keep these critical combat platforms flight-ready.”

Instead of creating a brand-new government bureaucracy from scratch, the campaign simply combines several existing upgrade programs that were already being managed by the Air Force acquisition office. AFMC has made significant efforts to expedite the return of bombers to the fleet following deep cycle overhauls. She reaffirmed that North Star demonstrates the bomber force is prepared to fight at any time.
The case for North Star is straightforward and the Air Force has made it clear. It is a documented, data-driven parts problem to deliver a measurable, coordinated fix. The responsive program has already cut mission impacting shortages by nearly two thirds in a matter of months. It did so without waiting for the B-52J upgrade program or the arrival of the new B-21 to solve the readiness gap.
To put it another way, bombers face more challenges than just the North Star campaign. Rather, it is the Air Force's most conspicuous attempt to stop a perilous decreasing trend that is evident throughout the whole military fleet.
The fleet of KC-46 tankers has also experienced this same pattern. In a June assessment, the Government Accountability Office said that the refueling force did not reach its availability and readiness targets between 2019 and 2025. Severe shortages of replacement parts and surprisingly high breakdown rates on the new tankers were the main causes of this catastrophe.
What the North Star campaign is buying time for is the B-21 Raider. The Air Force and Northrop Grumman announced in February that the first active B-21 remains on track to arrive at its base in South Dakota in 2027. However, news reports noted that this date is a revision from earlier military statements that promised deliveries in the mid-2020s.
The Commercial Engine Replacement Program is providing the most comprehensive structural response to the ongoing challenges. The goal of the project is to replace each B-52H bomber's eight outdated engines with new Rolls-Royce turbofans, along with a host of other new systems that will bring it up to the B-52J standard. On May 4, the program passed its Critical Design Review.
The CERP contract alone, under the B-52J umbrella, is worth up to $2.6 billion to supply over 600 new engines for the 76-plane fleet. The new engines are projected to cut fuel use by up to 30% and extend the bomber's flying distance past 11,000 miles (17,703 km). However, the same evaluation that made it possible for the program to proceed also revealed how far behind schedule it has fallen: the fleet recapitalization timeline has now extended into fiscal year 2033.
It won't be until 2027 that the first new engines designed for a real operational B-52 will be delivered. While the engine program dominates the news for the B-52, the B-1 bomber fleet is also undergoing its own major overhaul that the North Star campaign is trying to support. With the upcoming improvements, the Lancer will continue to fly alongside the B-2 stealth bomber into the late 2030s.
Before its external nuclear weapons hard points were disabled, the B-1 was first designed in the 1980s to fly supersonic under enemy radar as part of a dual mission set. While these pylons are being upgraded for conventional missiles today, less than half of the fleet is now prepared to fly at any given moment. System upgrades for the B-1 include new weapons mounts, which the Air Force says will increase the bomber's missile capacity by around 50%.
At the same time, the BONE is also receiving a modern software suite to update its systems for 21st century air warfare. Instead of merely postponing a significant decline, the USAF is investing in the North Star campaign's parts pipeline to sustain these vital airframes for another decade or longer. Readiness reports from earlier in the plane's life found that the fleet could only hit a 75% readiness rate, but it could crash down to 51% when the supply chain was outpaced by mission demands.
The North Star campaign is an attempt to optimize supply conditions through daily management rather than periodic surges of parts. North Star's timing is also inextricably linked to a catastrophe that befell the B-52 fleet three months prior. A top military official from the base called the crash completely unsurvivable. Records show this was the deadliest B-52 accident since 1982, and the first time one of these bombers was lost since a 2016 crash in Guam.
The B-52 Stratofortress is powered by eight aging engines, but the US Air Force will upgrade to the F130 engines from Rolls-Royce.
Shortly after taking off from Edwards Air Force Base on June 15, the B-52 BUFF crashed and killed all eight occupants. It was one of just two planes configured to conduct test runs in support of the Raytheon radar upgrade. Active-duty Airmen, government employees, and two Boeing employees, were among the victims.
Current information does not attribute this crash to maintenance delays or shortages of parts. Nevertheless, given that the initiative to install new engines is still years away from delivering its first upgraded aircraft, the tragedy underscores the grave operational risks of flying aircraft more than six decades old.
The next chapter in the story of the B-52 is now being written.
North Star treats a symptom of a much larger force structure problem. AFGSC must contend with an aging industrial base that can no longer reliably produce parts for engines and airframes designed in the 1950s and 1960s. Although it will help in the short term, ultimately that issue is one that a faster meeting cadence cannot fully resolve. The only long-term solution is to modernize.
The Air Force itself now believes that the TF33 engine line is unsustainable beyond 2030, regardless of how effectively spare parts are routed. While expediting current parts through improved coordination is a real and measurable improvement, this does not address the issue, as Defense News highlighted.
The campaign is being asked to reverse a decades-long trend with a process change rather than a fleet recapitalization because the mission-capable rate declines recorded which predate North Star completely. Its early results, if they are sustainable, will need to be maintained for years rather than months. Only then can they be considered proof that the underlying decline has been stopped rather than just halted.
A closer look at the last 'BUFFs' still standing.
The first B-52J flight test aircraft are scheduled to begin modifications at Boeing's San Antonio facility later this year. However, the new engines will not reach an actual bomber body until 2027. At the earliest, the upgraded B-52J is now projected to be ready for combat in 2033. This is eight years later than originally planned when the J-model initiative first started.
When the B-21 Raider arrives at its base next year, the load currently carried by 40-year-old B-1s and 60-year-old B-52s will be reduced for the first time. Still, the new Raider won't be able to significantly replace the old bomber force for many years after that initial delivery. Until then, the North Star campaign's daily meetings may carry on until the last B-1 is retired and the final B-52H is rebuilt for the next era of air warfare.
