Profits at Bondholder Rolls-Royce have risen by 148% for the six months to 30 June, with the firm making a profit of £287m during the past six months.
Revenues at the aerospace giant have also increased by 6% to £6.9bn.
Warren East, Chief Executive, said: “Rolls-Royce delivered encouraging year-on-year operational progress in the first six months of the year. Civil Aerospace large engine deliveries increased 27% and we made good further progress improving Trent XWB OE economics.
"Restructuring savings were ahead of plan. Together with a higher than expected benefit from long-term contract accounting adjustments, this resulted in a good set of results, with financial performance ahead of our expectations for the first half.
"Looking to the balance of the year, execution and delivery of a number of important milestones across our businesses will be key to achieving our full year expectations. Our outlook for full year profit and cash remains unchanged.”
