Air Force Clears B-52 Engine Design Review, Setting Stage for B-52J Upgrades

WASHINGTON, D.C. - The Air Force announced May 4 that its program to replace the 1960s-era engines on the B-52H Stratofortress has cleared its critical design review. This milestone clears the way for Boeing to begin modifying the first two bombers into the new B-52J configuration at its San Antonio facility later this year. The Commercial Engine Replacement Program will swap out the fleet's aging Pratt & Whitney TF33 turbofans for Rolls-Royce F130 engines, which offer better fuel efficiency, longer range and increased electrical power for modern sensors and weapons.

The engine overhaul is a central component of the service’s plan to operate the B-52 into the 2050s, which would push some airframes to nearly 100 years of service. As spare parts for the original engines become increasingly scarce, the Air Force is modernizing the 76-aircraft fleet to serve alongside the B-21 Raider while retiring the B-1B Lancer and B-2 Spirit. These upgrades, which also include new radar and subsystems, are intended to reverse a decline in readiness; the B-52’s mission-capable rate fell to 54% in fiscal 2024.

While the design review marks a major step forward, the program is roughly three years behind its original schedule. The Air Force now targets fiscal 2033 for initial operational capability, with total program costs estimated at $15 billion. Military oversight reports have warned that the current acquisition strategy carries risk, as the service plans to commit to low-rate production for dozens of aircraft before operational testing is finalized in 2032, potentially making future technical fixes more expensive.

WASHINGTON - Total commercial aircraft production in April 2026 rose to 133 aircraft, a slight increase from the 128 units produced in March, maintaining the momentum established at the end of the first quarter.

As expected, Narrowbody production made up the vast majority of activity with 103 aircraft, a four aircraft decrease from the 107 produced last month. Most notably, widebody output saw a healthy increase to 24 aircraft, up from 16 in March. This growth in the widebody segment was driven by a significant acceleration in the A350 and 787 programs, both of which operated at or above their current production target rates during the month. Regional jet production held steady at three aircraft, while turboprop production also recorded three units for the month. On a year-to-month (YTM) basis, total commercial aircraft production has reached 462 aircraft through the first four months of 2026. Narrowbodies continue to lead the market with 371 aircraft, followed by 75 widebodies. Regional jet and turboprop production remain modest contributors to the year’s totals, standing at 10 and 6 aircraft, respectively.

Average Production-to-Delivery Lead Times

Average production-to-delivery lead times saw a notable shift in April. While the widebody segment saw improvements, narrowbody lead times increased to an average of 31 days from production to delivery, a one-week rise over the 24 days recorded in March. This increase was driven by production-to-delivery bottlenecks for the A320neo family, which are resulting in a buildup of undelivered inventory and hurting Airbus’s ability to maintain a healthy delivery rate.

In stark contrast, widebody lead times reached a very healthy average of 23 days, which is a sharp decrease from previous months. This improvement is attributed to much stronger widebody production performance from both Boeing and Airbus after the programs had struggled earlier in the year. Furthermore, the bottleneck caused by stored inventory has largely dissipated as the remaining 787 inventory is now nearly cleared. This is allowing for a smoother, more direct flow from the factory line to the customer. Turboprop lead times stood at 161 days, reflecting the longer-cycle delivery schedules typical for that segment. No regional jet lead-time data was recorded for April due to a lack of paired events. Across all segments, the average lead time for April was 72 days.

Projected Deliveries

Forecast International estimates that Airbus and Boeing combined delivered approximately 107 aircraft in April 2026, which is a moderate increase from the 99 estimated in March. Airbus is projected to have delivered 60 aircraft, dominated by 51 A320neo-family narrowbodies. While the four A220 deliveries represent a dip from the previous month, the A320neo family showed a significant recovery toward its monthly production targets. Widebody deliveries for Airbus remained lean, consisting of two A330neos and three A350s. Boeing delivered an estimated 47 aircraft during the month, representing a slight improvement over the 45 delivered in March. This total was supported by 36 737 MAX aircraft, while widebody activity remained focused on finishing the inventory clearing process, including six 787s, three 777s, and two 767s.

BEEHIVE INDUSTRIES UNVEILS RAMPART TURBOFAN FOR CCA APPLICATIONS

Beehive Industries Unveils Rampart Turbofan for CCA Applications

Source: Beehive Industries


CENTENNIAL, Colo. - Propulsion startup Beehive Industries has unveiled a 1,000-pound-thrust turbofan engine called the Rampart. The Colorado-based company designed the engine specifically for Collaborative Combat Aircraft, or CCAs, which are intended to provide sensor and weapons support to manned tactical fighters like the Lockheed Martin F-35 and F-22. Beehive officials say the engine offers higher endurance and performance than the company’s smaller propulsion lines.

The Rampart enters a competitive landscape as the U.S. Air Force, U.S. Marine Corps and Royal Australian Air Force accelerate CCA flight testing. Because these uncrewed jets must maintain the speed and maneuverability of frontline fighters, they require high performance engines that can be produced at lower cost than traditional jet engines. The U.S. Air Force has already issued initial development contracts for similar engines to Honeywell and a joint venture between GE Aerospace and Kratos, while industry giants Pratt & Whitney and Rolls-Royce are also developing low-cost, lightweight alternatives.

Beehive’s expansion into larger turbofans follows its initial focus on the Frenzy line, which consists of smaller engines designed for long-range missiles and swarm drones. The company is currently preparing for flight tests of its 200 lbst Frenzy 6, supported by a $30 million development contract awarded by the Air Force in April. That funding is also designated to support the initial prototyping of the 100 lbst Frenzy 8 as the company scales its manufacturing for high-rate production.
