London-based Rolls-Royce won a $374 million order Monday to supply engines to the Boeing Corp. as part of the largest commercial jet aircraft deal in history. Rolls-Royce said in a statement it would supply 26 RB211 engines for three types of Boeing aircraft ordered by U.S.-based International Lease Finance Corporation (ILFC). The deal is part of a $5 billion commercial jet aircraft order, the largest in aviation history, announced last week by the leasing company.
