Perth — Commonwealth 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.

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 — allowing her to set enemies on fire with something other than secondaries. Her other primary difference is her smokescreen. Unlike the short deployment time, long-duration typical British cruiser smoke, Perth has a Crawling 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 mobile smoke screen, staying fully hidden while moving at speeds up to 12.5 knots, for over 2 minutes with all available modifications.

In the negative column, Perth’s armor-piercing rounds are not the improved AP of the regular tech tree British light cruisers, and her anti-aircraft suite is even weaker than that of stock hull Leander. Her short 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.

Pros:

• Second lowest detection radius of all Tier VI cruisers.
• Crawling Smoke Generator  consumable allows Perth to move at low speeds and take her smoke cloud with her.
• Has access to high explosive rounds, giving her more flexibility against angled targets and destroyers.
• Good handling characteristics: short rudder shift time, and a reasonably tight turning circle.
• Can choose between equipping either a Spotting Aircraft  or Catapult Fighter .
• Two fully upgraded Perths can maintain permanent smoke coverage by alternating use of their Crawling Smoke Generator .

Cons:

• Low health pool; 27,100 base hp is in the bottom third of Tier VI cruisers.
• Bow/stern armor can be overmatched by 283mm+ AP; unlike her sister ship Leander, Perth cannot recover health .
• Shortest main battery firing range of all Tier VI cruisers.
• Dreadfully bad anti-aircraft suite, and cannot equip Defensive AA Fire .
• Requires high resource investment into Special Upgrades and Commander Skills for optimum performance.
  

Research

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

Optimal Configuration

Upgrades

The recommended upgrades for Perth are as follows:

• Slot 1: Spotting Aircraft Modification 1 or Main Armaments Modification 1
• Slot 2: Hydroacoustic Search Modification 1 or Engine Room Protection
• Slot 3: Smoke Generator Modification 1 or Aiming Systems Modification 1
• Slot 4: Steering Gears Modification 1

More than any other ship in the game, Perth benefits from access to the Special Upgrades that are available through the Arsenal. Captains with access to the following are encouraged to mount them instead in their respective slots: Smoke Generator Modification 1 is first priority; Spotting Aircraft Modification 1 is especially useful on large maps; Hydroacoustic Search Modification 1 will better align your Hydroacoustic search duration with your upgraded smoke duration.

Commander Skills

Perth has more commander skill options available to her than Leander, simply by virtue of the fact she has high explosive shells available to her main battery. The two main specializations are towards DD-hunting or towards damage output.

For DD-hunters, taking Concealment Expert and Radio Location are critical, supplemented by quality of life skills.

For a more damage-oriented build, Pyrotechnician , Inertia Fuse for High Explosive, and Adrenalin Rush are core skills to chose.

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

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 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.

HMAS Perth’s bell was retrieved from her wreck by an Indonesian diving team in 1974 and subsequently presented to the Australian Government by the Indonesian Government. It now forms part of a commemorative display in the World War II gallery at the Australian War Memorial in Canberra, Australia.
