To ensure there was not any loss of performance due to the increase in displacement, it was a necessity to improve the propulsion machinery. While the internal layout was similar to her predecessors, new machinery was installed in place of the old. Boilers that were akin to the models used in ''contre-torpilleurs'' – which would operate at higher-pressure loads – and turbines that could be configured for multi-pressure work was installed. Ultimately this was able to increase power from 100,000 to 110,000 shaft horsepower; achieving a top speed above 32 knots. | To ensure there was not any loss of performance due to the increase in displacement, it was a necessity to improve the propulsion machinery.

? | In the end, she was a cruiser that shared design characteristics of the ''[[La Galissonnière]]''-class and cruiser [[Algerie|Algerié]]. Her hull was superficially similar to her predecessors; albeit with a more flared and narrow bow to increase sea keeping. Her superstructure was akin to the heavy cruiser: built around a central tower and a single funnel amidships. ''De Grasse'' used a combination of high tensile steel and duralumin – on the hull and superstructure respectively – to decrease displacement and top-weight. To save design time, a similar armour profile as ''[[La Galissonnière]]''-class was used on ''De Grasse'' as well. | + | In the end, she was a cruiser that shared design characteristics of the ''[[La Galissonnière]]''-class and cruiser ''[[Algerie|Algerié]]''.

De Grasse — French special premium Tier VI cruiser.
According to the draft design in 1938, the light cruiser De Grasse was developed from the La Galissonnière-class ships, and shared their main advantages: improved armor and good main battery guns. She had distinctive AA armament, increased speed, and slightly reinforced torpedo tubes.

Player Opinion
Performance
De Grasse is a Tier VI premium French Cruiser that is a development of the La Galissonnière class. They both feature triple 152mm turrets in a ABX configuration firing the same AP and HE shells, though De Grasse has a higher rate of fire and 0.3km higher range. Torpedo-wise, De Grasse features triple launchers instead of the twin launchers found on La Galissonnière, and thus has a longer reload on each mount. Both have unimpressive secondaries and weak AA. Maneuverability-wise, De Grasse is 2.5 knots faster, but has a 1.1 sec longer rudder shift time and a 40m wider turning circle. Both ships feature the engine boost consumable. Overall, De Grasse is fairly similar to La Galissonnière, and anybody used to her will feel right at home with De Grasse.
LittleWhiteMouse's Premium Ship Review: De Grasse from the NA forums.Pros:
- Faster reload time than other French cruisers with 152mm guns.
- Main battery turrets traverse quickly, taking only 15 seconds for a full turn.
- Torpedoes have a range of 9 km with 60 knot speed.
- Wide torpedo launching angles.
- High top speed which can be increased further with the Engine Boost consumable.
Cons:
- While her reload time is faster than both Émile Bertin's and La Gallissonniere’s, it is still slow compared to other cruisers carrying 152mm guns.
- De Grasse has only only three torpedoes per side.
- The ship’s rudder can be incapacitated very easily.
Research
Optimal Configuration
Upgrades
As a Tier VI cruiser with four upgrade slots, the following upgrades are recommended on De Grasse:
Slot 1
- Main Armaments Modification 1, as De Grasse's anti-air capabilities are not very good and it relies mainly on its main batteries to deal damage.
Slot 2
- Aiming Systems Modification 1, as aforementioned, her anti-air capabilities are not very good and the decrease in dispersion will help a little bit more.
Slot 4
- Steering Gears Modification 1, as she is a French light cruiser with a very weak rudder (easily incapacitated).
Slot 5
- Steering Gears Modification 2, to help with the already poor rudder shift time on the cruiser; she has the worst rudder shift out of all the Tier VI cruisers (with Budyonny second-worst at 8.6 seconds [top hull]).

Consumables
As a Tier VI French cruiser, De Grasse has all the same consumables as La Galissonnière but has a Catapult Fighter in a 4th slot as well; the following consumables are available on De Grasse:
She basically has the same consumables as Algerie and Charles Martel, but with the Catapult Fighter and Engine Boost consumables in switched positions.
It is highly recommended to mount premium Engine Boost II to maximize the usage of the ship's speed, and to mount premium Damage Control Party II if the player finds the rudder is incapacitated frequently. Premium Defensive Fire and Hydroacoustic search are optional, and the choice between the two is up to the player. Premium Catapult Fighter is not recommended.
Camouflage
As a premium ship, De Grasse comes included with Type 10 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, and increases the amount of experience she earns.
Signals
Like other French cruisers, De Grasse benefits significantly from signal flags that increase HE fire chance. Juliet Charlie may be used to mitigate the increased risk of detonation gained when mounting India X-Ray flags. November Foxtrot reduces the cool-down timer for consumables which is especially useful for the engine boost consumable. Sierra Mike is also highly recommended to increase the ship’s top speed. Special and Economic signal flags can be mounted to increase the experience and credit gain per battle.
