The ship has a significant advantage in terms of survivability due to the size of its crew, with 578 sailors it is one of the largest in the BR. The [[ammo racks|ammunition racks]] are located deep below the waterline and are protected by additional plating, which makes ammunition explosions very unlikely to occur. Moreover, the turrets and ammo elevators are equipped with 30 mm armor, which can reduce fragmentation damage caused by near-misses.
 +
 
 +
The ship's large size also serves as a form of protection as its hull is divided into 9 sections, a feature typically found on Heavy Cruisers, reducing damage from both torpedoes and bombs.

However, like other ships in its BR, the Duguay-Trouin does not have armor that can directly stop high-caliber SAP or HE shells. Typically for the light cruisers it is also unable to withstand damage from multiple enemy warships.

Mobility can be described in one word: average. Rudder turn speed varies between 5.4 second (not upgraded) to 4.05 second (Aced crew with maximum leadership), which is somewhat slower than most of the light cruisers of the BR when not upgraded, but the same as all the competitors when fully Aced. Guns can easily keep up with the turn rate thanks to their high horizontal targetting speed.

Four twin turrets provide an one of the highest damage outputs in the BR, comparable only with some of the US destroyers.

 +
* '''M1924 HE''' - large explosive filler, contact fuse, best against soft-skinned targets and external modules on the enemy warships

* '''M1924 SAP''' - good explosive filler, best against lightly armored targets, will dive into the ship to reach the internal modules
 +
* '''M1924 HE-TF''' - smallest explosive filler of the three, base fuse, particularly good when hitting a highly angled targets, will dive deeper into the ship bellows than SAP, but also is more prone to over-penetration and has less of a penetrative capability against the parallel targets

The Duguay-Trouin-class was developed from the 1915 proposal for a new class of cruisers, the first to be built domestically in France since 1906. Designated ''Project 171'' ships were originally to be much smaller and cheaper, armed with the 138.6 mm guns, but the reveal of the [[HMS Enterprise|British E-class]] along with the [[Omaha (Family)|American Omaha-class]] in 1920 forced French designers into a larger, better-armed and faster ships armed with the 155 mm guns. Just the increase in speed alone, from 30 to 34 knots, doubled the required shaft horse power from ~53 000 shp to ~100 600 shp.
 +
 
 +
Typically for the Treaty cruisers it enjoyed a minimal protection, accounting for just 2% of displacement. Cruisers of the time were described as "eggshells armed with hammers", being able to stop WW1-era 4 inch guns, but inadequate for the guns of the interwar period. Cruisers of the time were designed to outrun the ships they couldn't outgun. That said though: Duguay-Trouin-class was built with survivability in mind. The double-shell hull was subdivided with 17 transverse watertight bulkheads. Each of the four boiler rooms enjoyed a fully redundant subsystems. Similarly steering gear was fully electrically powered, but it had a manual backup. Electrical systems were also highly redundant, with turbogenerators located in the aft engine room near rear turrets, central engine room and below the bridge superstructure. Generators could be run individually or coupled. Later ships of the class included an additional diesel generators for an even higher degree of redundancy. Petrol and aviation fuel was stored in a special isolated tanks high in the stern of the ship, ensuring that any damage to the tanks wouldn't impact the vessel.  
 +
 
 +
Ship was praised for an excellent sea-keeping qualities, an exceptional turning circle, of just 750 meters at 28 knots, a low silhouette, spacious armored bridge, along with the flexibility and reliability of the machinery. The key criticism of the vessel was its high centre of gravity once the fuel load was depleted, resulting in roll of up to 18° during turns.
 +
 
 +
Interestingly ship design included space reserved for a passive hydrophone system along with the ultrasound pinger, but after the failed tests of the system on a smaller vessels plans for the refit were abandoned.

Ship's namesake is [[wikipedia:René Duguay-Trouin|René Duguay-Trouin]] (1673 – 1736), French privateer and Vice Admiral. He became famous for his command during the [[wikipedia:War of the Spanish Succession|War of the Spanish Succession]], including the victory during the [[wikipedia:Battle at The Lizard|Battle at The Lizard]], [[wikipedia:Battle of Rio de Janeiro|Battle of Rio de Janeiro]] and a capture of over 300 ships by 1709.

Description

The Duguay-Trouin-class, Duguay-Trouin, 1944 is a premium gift rank III French light cruiser with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update "Sky Guardians".

The ship has a significant advantage in terms of survivability due to the size of its crew, with 578 sailors it is one of the largest in the BR. The ammunition racks are located deep below the waterline and are protected by additional plating, which makes ammunition explosions very unlikely to occur. Moreover, the turrets and ammo elevators are equipped with 30 mm armor, which can reduce fragmentation damage caused by near-misses.

The ship's large size also serves as a form of protection as its hull is divided into 9 sections, a feature typically found on Heavy Cruisers, reducing damage from both torpedoes and bombs.

However, like other ships in its BR, the Duguay-Trouin does not have armor that can directly stop high-caliber SAP or HE shells. Typically for the light cruisers it is also unable to withstand damage from multiple enemy warships.

Mobility

Mobility can be described in one word: average. Rudder turn speed varies between 5.4 second (not upgraded) to 4.05 second (Aced crew with maximum leadership), which is somewhat slower than most of the light cruisers of the BR when not upgraded, but the same as all the competitors when fully Aced. Guns can easily keep up with the turn rate thanks to their high horizontal targetting speed.

Usage in battles

Duguay-Trouin is a very effective cruiser in its BR and lower, but has little means of responding against heavy cruisers from a higher BRs. It's a gun-centric ship, that can output a significant amount of damage even with the HE shells, but where it shines is the damage output from SAP shells compared to a similar shells from other vessels.

Ships is best used for pushing enemy points, out-ranging enemy destroyers and picking off problematic, but lightly armored targets. What it should avoid are direct exchanges of fire with the enemy heavy cruisers, or getting too close to the enemy ships armed with torpedoes, in particular Japanese Long Lance.

Pros and cons

Pros:

  • Very good damage output from the main guns
  • Effective anti-air cover
  • Good survivability with very well protected ammo racks

Cons:

  • Very limited capability to deal with a heavily armored targets due to the lack of AP shells
  • Lack of HE-TF or HE-VT shells
  • No torpedoes
  • Long fire solution calculation time
  • A very limited armor protection

History

The Duguay-Trouin-class was developed from the 1915 proposal for a new class of cruisers, the first to be built domestically in France since 1906. Designated Project 171 ships were originally to be much smaller and cheaper, armed with the 138.6 mm guns, but the reveal of the British E-class along with the American Omaha-class in 1920 forced French designers into a larger, better-armed and faster ships armed with the 155 mm guns. Just the increase in speed alone, from 30 to 34 knots, doubled the required shaft horse power from ~53 000 shp to ~100 600 shp.

Typically for the Treaty cruisers it enjoyed a minimal protection, accounting for just 2% of displacement. Cruisers of the time were described as "eggshells armed with hammers", being able to stop WW1-era 4 inch guns, but inadequate for the guns of the interwar period. Cruisers of the time were designed to outrun the ships they couldn't outgun. That said though: Duguay-Trouin-class was built with survivability in mind. The double-shell hull was subdivided with 17 transverse watertight bulkheads. Each of the four boiler rooms enjoyed a fully redundant subsystems. Similarly steering gear was fully electrically powered, but it had a manual backup. Electrical systems were also highly redundant, with turbogenerators located in the aft engine room near rear turrets, central engine room and below the bridge superstructure. Generators could be run individually or coupled. Later ships of the class included an additional diesel generators for an even higher degree of redundancy. Petrol and aviation fuel was stored in a special isolated tanks high in the stern of the ship, ensuring that any damage to the tanks wouldn't impact the vessel.

Ship was praised for an excellent sea-keeping qualities, an exceptional turning circle, of just 750 meters at 28 knots, a low silhouette, spacious armored bridge, along with the flexibility and reliability of the machinery. The key criticism of the vessel was its high centre of gravity once the fuel load was depleted, resulting in roll of up to 18° during turns.

Interestingly ship design included space reserved for a passive hydrophone system along with the ultrasound pinger, but after the failed tests of the system on a smaller vessels plans for the refit were abandoned.

Ship's namesake is René Duguay-Trouin (1673 – 1736), French privateer and Vice Admiral. He became famous for his command during the War of the Spanish Succession, including the victory during the Battle at The Lizard, Battle of Rio de Janeiro and a capture of over 300 ships by 1709.
