The most advanced British light cruiser among those designed during World War I. The ship's powerful propulsion allowed for high speeds. Her larger displacement helped strengthen the cruiser's artillery and torpedo armament as well as equip her with aircraft-handling gear.<!-- <br><br>{{Model3DViewer|171b0759c934427095b746aa9f4d910d}}-->

|Performance=<!-- write text about performance in battles below -->
''Emerald'' is the final evolution of the Royal Navy's cruiser designs based around single, centerline mounted 152mm guns.  Though she has seven total turrets, only six can be brought to bear on a single target at once; the turrets just aft of the bridge are mounted on either side of her funnels and can only fire on one side of the ship.  

Unfortunately, this represents a bit of a step back for the line, putting ''Emerald'' in much the same situation that ''[[Caledon]]'' was in at Tier III: she's badly outgunned by most opponents she will face.  Every other Tier V cruiser save ''[[Furutaka]]'' can get more barrels on target than ''Emerald'' can, and ''Furutaka''’s guns are significantly larger due to the Japanese cruiser line transitioning to heavy cruiser designs.  The situation gets even more unpalatable when ''Emerald'' finds herself up-tiered into Tier VII games (at least ''Caledon'' can only see opponents one tier higher). As icing on the cake, the citadel hitbox is easily penetrated and positively huge: an ''Emerald'' captain should never forget that exposing the ship's sides to any enemy ship larger than a destroyer is almost invariably fatal. 

Like ''Caledon'' and ''[[Danae]]'', captains looking to get the most out of their ''Emerald'' will have to play incredibly smart and make maximum use of her torpedoes and consumables to see that she survives deep into games.  Her stock torpedoes are equivalent to the upgraded ones on ''Danae'', with the torpedo module upgrade boosting their damage, while upgrading the 6.0 km range to 7.0 km.  ''Emerald'' is more sluggish on her rudder and has a larger turning circle than ''Danae'', so new captains should take some time to get to know her before putting her in situations that require precise maneuvering.  

''Emerald'' is an average ship in a tough spot with unfavorable matchmaking tiers.  Getting through — and past — her while working up the branch can be frustrating, but ''[[Leander]]'' makes the pain worthwhile.

|Pros=<!-- write list of positive points below. use * as in ordinary wiki-list. -->
* Has the lowest detection range of any Tier V cruiser.
* Gains access to the {{Smoke Generator}} consumable, while retaining access to the {{Repair Party}} consumable.
* Has a large number of torpedoes with six per side, eight with the upgraded hull.
* The firing arcs for her torpedoes are large which allows her to use them while presenting a sharp angle.

|Cons=<!-- write list of negative points below. use * as in ordinary wiki-list. -->
* Often has difficulty damaging battleships due to a lack of high explosive shells.
* Limited firing arcs on some of her main battery guns especially against targets aft of the ship.
* The citadel is quite large and sits high above the water making it easy to hit.
* Unlike her predecessors, has -2/+2 matchmaking and will frequently be matched up against Tier VII ships.
* Suffers immensely from being up-tiered due to short range torpedoes and frequently ineffective guns.

|Research=<!-- write text about priority sequence of research below -->
Captains are encouraged to research the Gun Fire Control System module first to extend ''Emerald''’s range before moving on to Hull (B) and the Torpedo module.

''{{#var:ship_name}}'' can equip the following consumables:
* '''Slot 1:'''  {{Damage Control Party}}
* '''Slot 2:'''  {{Repair Party}}
* '''Slot 3:'''  {{Hydroacoustic Search}}
* '''Slot 4:'''  {{Smoke Generator}} '''or''' {{Spotting Aircraft}} '''or''' {{Catapult Fighter}}

As a Royal Navy light cruiser, ''Emerald'' can be deadly to enemy destroyers, but also rather frail against them.  This makes it advisable to equip {{Hydroacoustic Search}} as soon as possible to spot the enemy ships as well as enemy torpedoes.  Also, her thin armor makes it highly advisable to equip {{Repair Party}} and {{Smoke Generator}}.  {{Catapult Fighter}} is not recommended due to the little protection it provides and {{Spotting Aircraft}} is not recommended due to potential difficulty in reaching out to your targets. However, some players may find {{Spotting Aircraft}} more useful than {{Smoke Generator}} due to the rather abysmal range of this cruiser.  But {{Smoke Generator}} can work very well in conjunction with {{Hydroacoustic Search}}, as enemy ships may find it rather tempting to launch torpedoes at the smoke cloud.

|Camouflage=<!-- write text about useful camouflage below -->
[[Ship:Camouflage#Standard Camouflage|Type 1, 2, or 5 camouflage]] can be equipped for credits; Types 2 or 5 are recommended at a minimum to reduce the accuracy of incoming shells.

===History===
====Design====
The "E" class cruisers were designed and ordered in response to German cruisers believed to be under construction during World War I, and those that did see service in raiding convoys like the ''Brummer'' class. These new cruisers were designed as enlarged versions of the preceding "D" (''[[Danae]]'') class cruisers, and speed was prioritized above all else. Therefore, greater dimensions of over 7,500 tons were required to house the more powerful propulsion system, capable of maintaining a 33 knot top speed, 4 knots faster than the previous D class. On the other hand, despite the larger size and greater displacement, the E class retained the same protective scheme used for older cruisers, and only one extra 6-inch (152mm) gun was added over the D class, bringing the armament of ''Emerald'' up to seven 152mm guns. Five were mounted on the centerline of the ship and two guns mounted on the sides amidship. 

Both ''Emerald'' and ''Enterprise'' were upgraded and rebuilt extensively before and during World War II. In 1929, quadruple torpedo tubes were fitted, giving them a comparatively massive advantage in torpedo armament over the previous classes of cruisers. Aircraft catapults were fitted on both ships in the mid-1930s, being placed amidships, requiring the after mast to be moved forward of the third funnel. This mast was latter converted into a tripod mast. Also in 1934, the funnels were made 5 feet taller. During world war 2, the two ships had their anti-aircraft armaments extensively augmented, using a variety of 12.7mm, 20mm and 40mm guns, although later during the war, this was at the expense of the aircraft catapult, and aft banks of torpedo tubes. ''Enterprise'' was fitted with an experimental twin 6-inch (152mm) gun turret, which replaced her forward super-firing single 6-inch mounts as compared to ''Emerald''.

Three cruisers were ordered to be built under the E class design, however; only two were completed. ''Euphrates'' was cancelled following the end of the first World War.  Construction on ''Emerald'' and ''Enterprise'' continued and the two ships were completed in 1926. 

====Service====
Commissioned in 1926 after long delays due to fiscal restrictions and decommissioning priorities, ''Emerald'' joined the Eastern Fleet, serving there until 1933.  ''Emerald'' was then inactive for just over a year, and once again joined the Eastern Fleet until 1937 when she was again paid off and placed on inactive status.  Re-activated for World War II, ''Emerald'' briefly joined the Northern Patrol until she was transferred to Halifax, Nova Scotia in October 1939 for convoy escort duties. She served in this capacity until 1940, when she received a special mission to transport gold to Canada as payment for war materials. In October 1940, she took part in Operation Medium, escorting the battleship HMS ''Revenge'' to the French port of Cherbourg.  In 1941, ''Emerald'' was transferred to the Indian Ocean for escort duties, participating in operations in Iraq and the Indian Ocean.

After the Japanese entry into the war, ''Emerald'' once again joined the Eastern Fleet, serving part of her tour as flagship of the Fast Group, continuing her service in the Indian Ocean. ''Emerald'' returned to the U.K. for refit in August 1942 and returned to the Eastern Fleet in early 1943 for escort duties until early 1944. Returning once again to the U.K., ''Emerald'' participated in the Normandy landings where she supported Gold Beach with naval gunfire until mid-July 1944. Placed in reserve in late 1944, ''Emerald'' became a designated target vessel and was sunk as a result in 1947. She was re-floated in 1948 and sold for scrapping in Scotland shortly after. ''Emerald'' earned two battle honours during her service.

''Enterprise'', like her sister, was delayed in completion until 1926, and upon completion was assigned to the East Indies through 1934.  During this period, her distinguishing twin turret was fitted.  She returned home for a major refit and overhaul, and rejoined the fleet in the East Indies in 1936, conducting transport duties to China station until 1938 when she was paid off.  Re-activated at the beginning of World War II, ''Enterprise'' joined the Halifax (Nova Scotia) Force until 1940, when she returned home to participate in the Norway Campaign, providing naval gunfire support to troops ashore.  Returning home again for quick refit, ''Enterprise'' joined Force H in the Mediterranean and took part in the action at Mers-el-Kébir against the French Fleet.

From 1940 through 1941, ''Enterprise'' was engaged in the South Atlantic and Indian Ocean hunting for German raiders, including ''Admiral Scheer''. In 1942 she was assigned to convoy escort on the Australian routes before briefly joining the Eastern fleet. ''Enterprise'' then returned home late in 1942 for an extensive refit and overhaul, which lasted until late 1943. Near the end of the year, ''Enterprise'' joined the Home Fleet and participated in the continental blockade in the Bay of Biscay, where, with HMS ''Glasgow'', she engaged in a short, sharp action with German torpedo boats and destroyers, sinking the ''[[T-22]]''-class ''T-25'' and ''T-26'' and the ''[[Z-23]]''-class ''Z-27''. ''Enterprise'' next participated in the Normandy invasion, providing naval gunfire support off Utah Beach before being placed in reserve early in 1945. ''Enterprise'' participated in repatriation transport duties until early 1946, when she was paid off and sold for scrapping. ''Enterprise'' earned four battle honours during her service.

===Historical Inaccuracies===
* ''Emerald''’ Hull (A) represents her early war (1939 to 1942) condition; however, this hull uses the triple torpedo tubes that had been replaced by quadruples long prior to the Second World War.
* The anti-aircraft armament for Hull (A) is historically accurate for ''Emerald'' between 1939 and 1942, except that the ship only had four quadruple 12.7mm (0.5-inch) machine gun mounts fitted, not the six she has in game.
* ''Emerald'''s Hull (B) has the anti-aircraft compliment of ''Emerald'' in her 1944 condition, however, the six (6) single 20mm Oerlikon guns were added after the aircraft catapult was removed, and the quadruple 40mm 'pompom' and twin 20mm Oerlikon mounts were added after the aft banks of torpedo tubes were removed. Both the catapult and torpedo tubes are still present on the in-game hull, however.
* The Mk.XXII 6-inch (152mm) guns on ''Emerald'' were outfitted with standard charge shells with a muzzle velocity of 853 mps (meters per second), however in game, the supercharges are used, with a velocity of 936 mps.
* Although ''Emerald'' uses the same 152mm Mk.XXII guns as ''[[Caledon]]'' and ''[[Danae]]'', ''Emerald'' — like other regular Royal Navy light cruisers in-game — only gets access to AP shells.  Historically, ships using the Mk.XXII gun were outfitted with both AP/CPBC (Common Pointed Ballistic Cap) as well as HE shells.
