Latouche-Tréville is a F70 type anti-submarine frigate of the French Marine Nationale. She is the third French vessel named after the 18-19th century politician and admiral Louis-René Levassor de Latouche Tréville.

Note: The French navy does not use the term "destroyer" for its ships. Thus, some large ships, referred to as "frigates", are registered as destroyers.

Service history

In November 2006 and again in June 2010, Latouche Treville visited London on diplomatic duties, and was moored alongside the Second World War cruiser, HMS Belfast. In the autumn of 2009, while attached to an international force of NATO vessels, Latouche Treville visited Portsmouth Naval Base, UK, with vessels of the Dutch, Norwegian, Spanish and Turkish navies.
