(Reuters) -GE Aerospace's CEO said on Wednesday he is seeing supply chain improvements that will support a 15% to 20% increase in deliveries this year of jet engines used on popular narrowbody aircraft, after snags challenged deliveries in 2024.

CEO Larry Culp also told the Bernstein Strategic Decisions conference that the engine maker pledged to be "completely in sync" with customer Boeing ( BA ), as the U.S. planemaker gradually grows production of its strong-selling 737 MAX to a monthly rate of 38 and possibly above this year. GE Aerospace, however, is still expecting a hit of more than $500 million from tariffs due to a U.S.-led trade war.
