It also hinted in its statement at further cuts to a global workforce currently at 55,000.

The announcement to reduce staff numbers by almost five percent comes after Rolls had last month slashed its earnings forecasts partly as a result of Western trade sanctions against Russia over the Ukraine crisis.

Meanwhile in May, Rolls-Royce shocked investors when it issued a profit warning at its marine division, which has been beset by production problems. The group has been hit hard also by adverse foreign exchange movements.

"Rolls-Royce today announces additional headcount reductions as part of an intensified programme to improve operational efficiency and reduce cost," the company said in a statement after it cut more than 400 jobs at its defence unit in early 2014 owing to government budget cuts.

"We now propose a restructuring plan that will reduce headcount by 2,600 over the next 18 months, principally in our Aerospace division. The majority of this reduction will be achieved in 2015," the statement added.

Rolls said its restructuring plan would result in incremental costs of about 120 million pounds (USD192 million, 154 million euros) over the next two years.

But it expects also to eventually deliver annualised cost savings of about 80 million pounds thanks to the job cuts aswell as a move to reorganise the company into two divisions Aerospace and  Land & Sea. Rolls makes power systems also for submarines.

Rolls announced that David Smith had been appointed as its chief financial officer with immediate effect, replacing long-serving employee Mark Morris.

Smith joined Rolls-Royce earlier this year from US car giant Ford, taking up the role of chief financial officer at the group's aerospace division.

"We are taking determined management action and accelerating our progress on cost," Rolls-Royce chief executive John Rishton said in the statement.

"The measures announced today will not be the last, however they will contribute towards Rolls-Royce becoming a stronger and more profitable company."
