Georges Leygues-class Destroyer

From Canadian Power Wiki

Destroyers Dupleix (D641) and Preble (DDG-88) in the Arabian Sea on February 21, 2006.
The Georges Leygues-class (Type F70) is a class of anti-submarine destroyers of the French Navy. They are multi-role ships due to their Exocet and Crotale missile armament, making them especially suitable for the defence of strategic positions, show of force operations, or as high seas escorts.

The superstructures were built to optimise resistance to the blast from nuclear explosions.

The F70 is internationally labelled an "anti-submarine destroyer" (hence the "D" in the hull numbers), though the French do not use the term and refer to the ships as "frigates".

The last three ships of the class had their bridges raised one deck to overcome problems experienced by the first four in bad weather, as well as being equipped with DSBV 61 passive linear towed array sonar and several other upgraded systems.
