Le Terrible is a Triomphant-class strategic nuclear submarine of the French Navy. The boat was launched on 21 March 2008 [8]

On 27 January 2010, at 9h25, Le Terrible launched an M51 SLBM from underwater, in Audierne Bay.[9] The missile reached its target 2,000 kilometres (1,200 mi) off North Carolina; the 4,500-kilometre (2,800 mi) flight took about 20 minutes.[10]

The submarine was put into service on 20 September 2010 armed with the 16 M51 missiles.[2] Terrible is fitted with a new SYCOBS combat system (SYstem de COmbat Barracuda-SSBN) which will also be installed on the new Barracuda class SSNs.[11][12]

In July 2017 French president Macron visited the submarine in the Atlantic and took part in a simulated missile launch.[13]
