Overall, the armor of the HMS Arethusa is competitive for light cruisers in the 5.0-5.3 BR bracket. The magazine is located beneath the waterline and between two major fuel tanks that is encased in 3 inches/76.3 mm of armor. With a crew of 623 sailors and a main belt consisting of 2.25 inches of RHA, the Arethusa can withstand most destroyer-grade shells (127 mm and under) with relative ease assuming proper angling and range is kept above 5000 m. This however is not the case when facing cruisers as many of the cruisers that the Arethusa faces will have more than enough penetration to pierce the ship. Even if range is maintained, the chances that a shell will penetrate the ship remains high as the deck armor is worse than even the HMS Enterprise. With this in mind, players of the Arethusa should keep range above 8000 m to ensure a decent chance of shells non-penning the Arethusa's armor.

Armament

Primary armament

3 х Turret2 x 6 inch/50 BL Mark XXIII cannon
Ammunition400 rounds
Vertical guidance-5° / 60°

The primary armament of the HMS Arethusa consists of 6 inch/50 BL Mark XXIII cannons mounted in three twin-turrets for a total of 6 cannons. These cannons are known for their high firing arcs and fast reload of 7.5 seconds (with ace crew). These cannons are also quite accurate with little to no dispersion below 12,500 m. With good firing angles, good accuracy, and a menacingly short reload, this armament can be a force to reckon with.

  • The stock HE shell comes with just under 4 kg of TNT equivalent which can make quick work of most destroyers around its battle-rating. While this shell will not do too much to cruisers, it can be helpful in starting fires or knocking out crew in exposed weapon positions.
  • The Semi-Armor Piercing shell is where the 6 inch guns can shine. With 1.78 kg of TNT equivalent and 87 mm of pen at 7500 m (at 30 degrees of angle) these shells can through most light cruiser's belt armor assuming a decent location is hit. These shells are also great for dealing with destroyers as the fuze sensitivity is just 7 mm and a delay of 8 m. This means that the fuze can be set off by the destroyers thin layer of armor then explode inside the ship causing often fatal damage.
  • The time fuze and variable time fuze shells make for relatively easy AA work as the high explosive mass (3.96 kg equivalent) and large activation distance (240 m arming and 16 m exploding) will make most pilots think twice before attempting an attack run on you. The major drawback that the HMS Arethusa faces is that the 6 inch guns do not have access to a full AP shell. This results in a poor ability to cause significant damage to heavy cruisers or battleships at any significant range. While this can be slightly countered by closing the distance and engaging with semi-armor piercing shells, it cannot hope to engage at ranges above 7,500 m against heavy cruisers or battleships.

Usage in battles

The Arethusa is a general improvement over the Enterprise in all but a few ways. Firstly, the Arethusa features a better main armament. While the number of guns goes down to six, the broadside is up to six thanks to the three dual-gunned superfiring turrets. These guns also have a better RoF, firing a shot every 7.5 seconds. This, combined with the Arethusa's good turret traverse, can make this ship a monster at medium-to-close range. Carrying on from the Enterprise, the Arethusa still bolsters a powerful AA screen, but now with better DP guns thanks to the dual-mounted 4-inch guns, with a 3 second reload. These guns can be deadly both to large aircraft and to enemy destroyers and patrol boats, giving the Arethusa more survivability at close range than its predecessor. It also still features the fast torpedoes of the Enterprise, as well as good turning time.

The Arethusa does sacrifice some elements of its design. Firstly, it's a slow ship, doing just 26 knots when stock. It also inherits the poor armour of the Enterprise, with the addition of having even worse deck armour (making this ship vulnerable to bombs and rockets) and weaker belt armour. This, combined with the ship's low crew tally, means it struggles to take on a good amount of damage, especially from other cruisers. This ship can still be played effectively against light cruisers and destroyers, but Arethusa players should be cautious around the armoured light cruisers of Russia and America, as well as heavy cruisers of any design, which can punish the Arethusa's small size and poor armour.

Pros and cons

Pros:

  • Fast firing and accurate broadside can be a menace for light cruisers and destroyers
  • Fantastic AA armament, effective against aircraft of all sizes and types
  • Decent secondary armament with good RoF can give destroyers and patrol boats issues
  • Good turn time allows for good close quarters movement

Cons:

  • Lack of true AP shells can make heavily armoured cruisers a challenge, especially a long range
  • Only six guns on broadside can feel weak at times
  • Poor armour, even other light cruisers can punish this ship
  • Poor top speed can make repositioning and evasive manoeuvres difficult

History

HMS Arethusa as seen in 1942.

HMS Arethusa was the lead ship of her class, a set of four light cruisers built for the Royal Navy. Designed as a lighter version of the Leander class to counter Merchant-raider ships, they had a smaller displacement and armament but were big enough to serve as fleet cruisers. Commissioned in 1935, Arethusa served in the Mediterranean theatre before the outbreak of war, and later participated in a variety of conflicts including the Norwegian campaign and Mediterranean campaign. Struck by a torpedo in late 1942, she was inoperational until late 1943 and didn’t see active service until the D-Day landings in June of 1944. She had the honour of ferrying King George VI over the English channel to inspect the Allied forces in Normandy, but was later damaged by a naval mine and put out of service for the rest of the war. She was used for weapons trials until 1949, and subsequently scrapped.

Design and development

In the 1930s, there was serious concern over the potency of armed merchant raiders (merchant ships retrofitted with heavy armament), and as a result, the Royal Navy ordered a new class of vessels to counter these ships. The new vessel featured a toned-down version of Leander’s hull, with less armament. Even so, they were able to outgun (and possibly outrun) merchant cruisers by a fair margin. The Arethusa herself displaced just 5220 tons standard, and was capable of making 32 knots (59 km/h).

The Arethusa was armed with six 6-inch (152 mm) BL Mk 23 guns in three dual turrets - two fore (in the ‘A’ and ‘B’ positions) and one aft (in the ‘Y’ position). Her secondary armament was composed of four single 4-inch (102 mm) guns, though this was replaced in a later refit. Her anti-aircraft armament was initially scarce, but was improved over time. She carried two triple 533 mm torpedo tubes in beam positions. 

Arethusa was laid down in 1933, and launched in March of 1934. After completion, she was commissioned in 1935.

Operational history

After her commissioning, the Arethusa was assigned to the British Mediterranean squadron, and remained there at the start of the Second World War. She was then recalled to the British Home Fleet, and subsequently served in the Norwegian campaign. In June of 1940, she joined Force H at Gibraltar, and participated in the attack on French Forces based at Mers-el-Kebir. She later participated in the Hunt for Bismarck, and was later employed on convoy escort duties in the Mediterranean.

In November of 1942, Arethusa was struck by an Italian torpedo that caused severe damage; after temporary repairs, she was sent to the Charleston dockyard in the US and remained there until late 1943. During this time, her anti-aircraft armament was improved significantly, and she was fitted with new dual 4-inch mountings. After her return to service, she participated in the D-Day landings and provided fire support for the forces landing at Sword Beach. She was also given the honor of carrying King George VI across the English Channel to inspect allied forces in the Normandy region. However, she was hit by a mine several days later and sent back to the shipyards for repair. Arethusa saw little service for the rest of the war, and was placed into reserve in November of 1945. There were plans to sell her to the Netherlands navy, but these plans failed to come through and Arethusa was eventually scrapped by 1950.

Devblog

The development of the Arethusa-class light cruisers began because their predecessors - type Leander ships, were not very suitable for fleet operations at sea nor as a lead destroyer. Type Leander cruisers didn't have the maneuverability to be leaders, nor did they meet the minimum silhouette requirements for night operations. British engineers had to create a new, lighter, and more maneuverable ship based on the Leander.

The result of this endeavour was the creation of the Arethusa-class in the early 1930s - a light cruiser design based on the Leander-class, with reductions in firepower, protection and other aspects to accomodate for weight savings. The design was soon approved for construction, with six ships being initially ordered, although five were actually built in the end.

HMS Arethusa, the lead ship of her class, was laid down in January 1933, being commissioned in May 1935. Upon her completion, HMS Arethusa was immediately assigned to the Mediterranean, where she would also witness the outbreak of WWII in September 1939. Early in the war, HMS Arethusa operated off the coast of Norway, assisted in the evacuation of troops from France in 1940 and protected numerous Allied convoys in the Atlantic and Mediterranean.

Later in the war, in 1942, HMS Arethusa suffered heavy damages as a result of an airborne torpedo attack by axis forces, knocking the ship out of action for almost 2 years before finally being repaired in the US. Arethusa's final major operation of WWII were the Allied landings in Normandy in 1944. HMS Arethusa was put in reserve in the immediate postwar years and was later scrapped in May 1950.
