France successfully test-fired on Wednesday its new M51 strategic missile from a nuclear submarine, the first test at sea after three land-based firings, the defence ministry said.
France's newest strategic nuclear submarine "Le Terrible" launched the test at 9:25 am (0825 GMT) from the Audierne Bay in the Atlantic and "everything went as planned" said a statement from the defence ministry.
The M51 has a range of 8,000 kilometres (5,000 miles) and enjoys better accuracy than the current M45 ballistic missile carried by France's four nuclear-armed submarines.
