LONDON — British engineering giant Rolls-Royce has urged the UK government to make a timely decision on financial support for its proposed next-generation narrowbody aircraft engine, arguing that the project could secure Britain's position as a global aerospace leader.

The company says the programme, centred on its advanced UltraFan engine technology, could generate around 40,000 jobs across the UK supply chain while strengthening exports and advanced manufacturing. However, Rolls-Royce has cautioned that delays in government support may force it to consider alternative manufacturing locations, including Germany or the United States.

Chief Executive Tufan Erginbilgic said a decision is needed soon because major aircraft manufacturers are expected to choose engine suppliers for future single-aisle aircraft within the next two years. The company believes the project would mark its return to the lucrative narrowbody aircraft market after more than a decade away.

Industry analysts say the investment could reinforce Britain's reputation as a world leader in aerospace engineering while supporting high-skilled employment and long-term industrial growth. The government's decision is expected to be closely watched by investors, manufacturers and the wider aviation sector.
