Tourville-class frigate

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, and active Very Low Frequency (VLF) 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.

Optimized for anti-submarine warfare, and carrying towed as well as hull-mounted sonar arrays, the Tourville's were typically placed in the destroyer category of warship and carry destroyer pennant numbers. Similar in many regards to the unmodified destroyers, they carried a similar combination of sensors, naval guns, anti-ship and anti-submarine weapons, aircraft and surface-to-air missiles. Additionally, they were well-regarded for their seakeeping, serving much of their careers in the Atlantic rather than with France's Mediterranean fleet.

Ships
The three ships of the class, D612 De Grasse, D611 Duguay-Trouin and the D610 Tourville, are named major figures from French naval history. De Grasse and Tourville were French admirals and Duguay-Trouin coming to fame as a privateer.

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