Essentially an enlargement of the C 65 design, the F 67 incorporated from the outset a double hangar capable of accommodating two Lynx ASW helicopters, and MM38 Exocet SSMs. There was also a doubling-up of installed horsepower and the ships reverted to a conventional two-half machinery installation.
As originally conceived Tourville was to have received the same sensor outfit as Aconit. However, while the new ships were under construction it was decided to fit the new DRBV26 air surveillance radar, and replace the complex DRBV13 with a DRBV51B (initially DRBV50) target designation radar. A new lightweight variant of the DRBC32 fire control radar was fitted. The ships retained the SENIT 3 tactical data system trialled in Aconit.
Tourville and Duguay-Trouin were completed with a third 100mm mounting atop the hangar, but it was decided at an early stage to replace this by a Crotale point-defence SAM system. De Grasse was completed with only the two forward guns in place. These were the first French ships of destroyer size designed from the outset to carry helicopters. The large double hangar was served by a SPHEX traverse system, and in the centre of the helicopter deck there was a grille for use with the Harpoon securing device. Two pairs of non-retractable stabilizers were fitted.
De Grasse incorporated a number of Improvements over the earlier ships, including superior habitability. Her boilers were modified to edible her to burn distillate fuel, and this modification has since been extended to her two sisters.
