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

On 27 January 2010, Le Terrible launched an M51 SLBM from underwater in Audierne Bay. 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.

The submarine was put into service on 20 September 2010 armed with 16 M51 missiles. 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.

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