has completed the acquisition of Siemens’ electric and hybrid-electric
aerospace propulsion activities, formerly known as the eAircraft business.
The acquisition, initially announced in June, provides Rolls-Royce with “vital skills, expertise, and new technology” as it works to develop a new class of quieter and cleaner air transport, according to Rolls-Royce Electrical director Rob Watson.

eAircraft team has already collaborated with Rolls-Royce on the E-Fan X
demonstrator project with Airbus. For that project, Rolls-Royce is developing a
2.5-megawatt hybrid-electric propulsion system suitable for regional aircraft. Rolls-Royce
is also developing a hybrid version of its M250 gas turbine engine, which will
have an expected power range from 500 kilowatts to 1 megawatt, ideal for small
