Designed for outstanding reliability, the BR725 will be supported by the industry-leading Rolls-Royce CorporateCare® services programme.

Compared with the highly successful BR710, the BR725 is more powerful, with a maximum thrust of 17,000lb, is more than 4 dB cumulative quieter, has 4 per cent better specific fuel consumption and shows a 21 per cent improvement in NOx emissions. Design features include a 50-inch diameter fan assembly made up of 24 “swept” titanium blades for improved aerodynamic efficiency and lower noise.

The development phase has been running smoothly so far. The selection of suppliers is complete. New capable suppliers have been included in the supply chain and very good conditions have been established allowing unit cost targets to be achieved. So far, all schedules have been met on time. This allowed the Critical Design Review to be successfully completed in November 2007.
