Perth — Australian premium Tier VI cruiser.

This warship was built in the United Kingdom, based on a reworked design of Leander-class cruisers with a modified arrangement of the propulsion unit. She was similar to her prototype in terms of armament, but had a different armor layout. In 1939, the ship was commissioned into the Royal Australian Navy.

Perth first went on sale on 18 November 2016 on the NA servers, and on 11 November 2016 on the EU servers.

Player Opinion

Performance

Perth is a sister ship to Tier VI British cruiser Leander; however, she has some significant differences. Most notably, she carries a high explosive round — like Belfast (and unlike her sister ship) — allowing her to set enemies on fire with something other than secondaries. Her other primary difference is her smoke screen. Unlike the short deployment time high staying time of typical British cruiser smoke, Perth has a Smoke Generator that deploys smoke continuously for 90 seconds, but each individual cloud of smoke only lasts for 10. This allows Perth to create a "moving smokescreen" so to speak, enabling her to remain invisible for a full 100 seconds if moving at speeds less than 12.5 knots.

In the negative column, Perth’s armor piercing rounds are not the "super AP" of the other British light cruisers, and her anti-aircraft suite is even weaker than that of stock hull Leander. Her low main battery firing range also means she must be played very carefully or she will be quickly removed from the battle by anything that can citadel her; which is, unfortunately, anything in the game with cruiser caliber guns or better. When her short firing range is combined with her woefully mediocre anti-aircraft suite, Perth’s ability to equip either a Spotting Aircraft or a Catapult Fighter — something Leander can't do — becomes an important choice; either will give her some spotting ability outside of her smoke screen, but one will increase her range and the other will help cover her from enemy aircraft.

LittleWhiteMouse's Premium Ship Review: Perth from the NA forums

Pros:

• Lowest detection radius of all Tier VI cruisers.
• Has access to high explosive rounds, giving her more flexibility against angled targets and destroyers.
• Good handling charateristics: short rudder shift time, and tight turning circle.
• Comes with a unique version of the Smoke Generator consumable that allows Perth to move at low speeds and take her smoke cloud with her.
• Can choose between equipping either a Spotting Aircraft or Catapult Fighter.

Cons:

• Loses access to Repair Party that comes standard on sister ship Leander.
• Dreadfully bad anti-aircraft suite, and cannot equip Defensive AA Fire.
• Low health pool; narrowly misses out on having the least health of any Tier VI cruiser (Nürnberg retains that honor).
• Shortest main battery firing range of all Tier VI cruisers.

Research

As a premium ship, Perth doesn't have any upgrades to research.

Optimal Configuration

Upgrades

Like most mid-tier cruisers, Perth lacks access to key upgrade slots that allow her to improve her performance significantly. As such, most of her recommended upgrade choices are fairly self-explanatory: Main Armaments Modification 1 in Upgrade Slot 1, Aiming Systems Modification 1 in Upgrade Slot 2, either Damage Control System Modification 1 or Propulsion Modification 1 in Upgrade Slot 4, and a choice of Propulsion Modification 2 or Steering Gears Modification 2 in Upgrade Slot 5. Perth’s mediocre anti-aircraft guns are not worth investing any points into improving.

Commander Skills

Perth has more commander skill options available to her, simply by virtue of the fact she has high explosive shells available to her main battery. Skills such as Expert Loader or Demolition Expert are not wasted on her as they would be on her cousin in the Royal Navy cruiser branch, Leander. In point of fact, Demolition Expert might be the best Tier 4 skill available to Perth commanders. Key skills in any Perth commander build are Expert Marksman at Tier 2 and Superintendent at Tier 3.

Investing commander skill points into improving Perth’s anti-aircraft defenses is not recommended.

Consumables

Perth retains the dependency that her cruiser cousins in the regular Royal Navy tech tree have on their consumables; subsequently, premium versions of ALL consumables are recommended. Smoke Generator II and Damage Control Party II are particularly critical given their impact to to her survivability.

Camouflage

As a premium ship, Perth 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.

History

Design

HMAS Perth was designed and constructed as a modified Leander class light cruiser. The original design was intended to fulfill the desire for a cruiser armed with 152mm to serve with fleets. Perth was fitted with the same armament used on the Leander class. The primary difference between Perth and her older sister ships was the adoption of segmented machinery spaces. This allowed for the ship to continue operating should one engine room become inoperable. The main belt armor was subsequently lengthened to protect her larger machinery spaces and the beam of the ship was increased slightly to improve her stability. Two funnels were installed instead of a single funnel due to the split machinery spaces. This limited the space available on deck and prevented a seaplane catapult from being mounted when the ship was first being fitted out. She later received a shortened catapult for use with the Supermarine Seagull.

Perth herself did not undergo many refits or modifications throughout her career. As completed, her 102mm guns were fitted in single mountings but this was changed to double mounts before she was transferred to the Royal Australian Navy. She also received several small caliber anti-aircraft guns.

Though she saw service mostly in the Royal Australian Navy, Perth was built in the United Kingdom and commissioned into the Royal Navy as HMS Amphion. Her name was later changed when she was transferred to Australia.

Service

Perth joined the Royal Navy in July 1936, and served her entire inter-war period in the North and South Atlantic. Three years after her commissioning, in July 1939, she was sold to the Royal Australian Navy, becoming HMAS Perth. Her first wartime station became the West Indies, and she operated in the Caribbean until March 1940, when she began convoy escort duties in the Indian Ocean. Redeployed to the Mediterranean in late 1940, Perth operated in support of the Malta convoys, where she received minor damage.

Early 1941 saw Perth engaged in operations in the Aegean Sea, where she escorted convoys bringing reinforcements to Greece. Perth also participated in the Battle of Cape Matapan in March. Beginning in April 1941, Perth continued to support convoys to and from Greece, this time as part of the evacuations. Remaining as part of the naval presence in the Aegean and central Mediterranean, Perth suffered significant damage from an air attack while engaged in support of Allied forces during the Battle of Crete. She received temporary repairs, then began operations in support of Allied troops in Vichy Syria before being replaced by HMAS Hobart in July 1941, sailing for Australia and an extensive refit.

Perth put to sea again in late November 1941, just in time for the Japanese entry into the war. Assigned to the ABDA command, Perth joined the combined Allied naval forces in attempting to disrupt Japanese landings in the Dutch East Indies. Perth was present for the Battle of the Java Sea in late February of 1942, and along with USS Houston, managed to survive that defeat. HMAS Perth and USS Houston were attempting to make port at Tjilatjap, Sumatra, and from there escape to Australia when, on 28 February, they sailed into a Japanese landing force, the presence of which Allied intelligence was unaware.

In the resulting Battle of the Sunda Strait, USS Houston and HMAS Perth, both low on ammunition, attempted to fight their way through the strait while simultaneously firing on the escorts of the invasion force. The action was confused with both Houston and Perth being sunk, though not before indirectly causing the loss of several transports to Japanese friendly fire in what may well have been the largest sustained torpedo attack of the war.
