LONDON—Boeing’s defense chief said on Sunday it had learned lessons from a contract to supply the U.S. presidency with new Air Force One aircraft, which has cost the planemaker almost $1 billion in charges and is up to three years behind schedule.
Ted Colbert did not give details of learnings, but said they had contributed to a new schedule for the two planes that has seen deliveries pushed back to 2026 and 2027.
