Many European nations have pledged to significantly increase defence budgets in response to Russia’s invasion of Ukraine and as U.S. President Donald Trump’s administration has threatened to scale back military support for the region.

U.S. drone-maker Anduril and German defence giant Rheinmetall said on Wednesday they will link up to build military drones for European markets, in a sign of Europe leveraging American technology to boost military capabilities.

Thomas Laliberty, president of Land & Air Defense Systems at Raytheon, said there were no easy replacements for its weapons in Europe and he expected the firm to maintain a long-term footprint on the continent, including through new partnerships.
