CEO Warren East, who took the helm in July, wants to cut the company's cost base by 150-200 million pounds (USD216-USD288 million) a year by 2017.
Fewer than 50 senior managers at Rolls-Royce, or roughly a quarter of managers at that level, will leave over the coming months, according to the Financial Times newspaper.

"The restructuring of our senior management will result in a small number of people leaving the business," a spokesman for Rolls-Royce said on Thursday evening.
Most of the job cuts will affect managers reporting directly to East or one of the business presidents of its civil aero-engines, defence, nuclear, marine, and power systems units.

East is under pressure to reverse the fortunes of the jet-engine maker after four profit warnings in just over a year, and after U.S. activist investor ValueAct amassed a 10 percent stake in the company and pressed for a board seat.
