Air Force One Replacement Delay Pushes VC-25B Entry to 2029

The Air Force One replacement delay has pushed the next-generation VC-25B program's timeline once again, with the U.S. Air Force projecting first delivery in mid-2028. That date represents a significant improvement over a previously re-baselined 2029 delivery estimate — reportedly pulled forward by roughly one year through schedule-recovery efforts — but still marks a dramatic slip from the program's original 2024 target.

Although physical delivery is expected in 2028, operational testing is slated to run through September of that year, with initial operational capability not anticipated until December 2029. To bridge the gap, the Air Force has introduced an interim modified transport aircraft scheduled for rollout in summer 2026, buying time for the aging VC-25A fleet while the new jets complete qualification.

Program Challenges and Costs

The VC-25B program, based on the Boeing 747-8, has been battered by compounding setbacks: the mid-program termination of interior outfitter GDC Technics, COVID-19 supply chain disruptions, and the demanding technical requirements of nuclear hardening and advanced communications integration. The cumulative contract value now exceeds $4.3 billion, including a recent $15.5 million modification for communications equipment. Meanwhile, the two existing VC-25As — modified Boeing 747-200Bs delivered in 1990 — are well past the 35-year mark and require escalating maintenance to remain mission-capable until the replacement fleet reaches full operational status.
