The F67 type is a class of large high-sea (Blue water) Destroyers of the French Navy specialised in anti-submarine warfare. They have anti-air and anti-surface capabilities.

Between 1994 and 1996, the Tourville and the De Grasse were refitted with the modern SLASM anti-submarine system, an active Very Low Frequencies sonar

Design

The ships are an enlarged version of the F65 class frigate Aconit. They have two shaft steam turbine machinery and a double hangar for two Lynx helicopters. They were the first ships fitted with the marine version of the Crotale surface to air missile system. A Malafon anti submarine missile system was fitted when the ships were built but this was removed during refits in the late 1980s

Ships

The three ships of the class, D612 De Grasse, D611 Duguay-Trouin and the D610 Tourville, are named after famous French sailors.

The three ships of the class were all built by Arsenal de Lorient
