Description

The Portland-class, USS Portland (CA-33), 1942, also known as "Sweet Pea', was the lead ship of her class. Being laid down in February 1930, she would be commissioned in February 1933, going on to serve through the entirety of WW2. Crucially, she would play a vital role in the opening of the war in the Pacific, screening the carriers at the Battle of the Coral Sea, Midway, and Guadalcanal. She would also play a role in the Aleutian Campaign before returning for the Battle of Leyte Gulf. With the cessation of hostilities, she would help with transporting troops back to the US before reporting for decommissioning in 1946. Notably, Pensacola was one of the few ships that served through the whole war without missing any major battles, and also received 16 battle stars; one of the most decorated USN ships of WW2.

USS Portland was introduced in Update 1.97 "Viking Fury". Compared to other heavy cruisers of the rank like the USS Pensacola that it precedes, it has a smaller battery of 9 x 8-inch guns. In exchange, it gains extra 1.1-inch and 20 mm guns, granting a much stronger anti-aircraft battery than measly heavy machine guns. The main weakness however is the weak armour, less than that of many light cruisers, as it had to be sacrificed to gain an 8-inch battery on treaty-era heavy cruisers.

USS Portland's survivability is rather mediocre for an American heavy cruiser, and rather weak compared to the enemies it often faces in battle. Portland has a main armour belt of just 57.15 mm of RHA, which can be easily penetrated by SAP and AP shells above 127 mm calibre. The magazines are protected by 146 mm of armour and sit below the waterline, meaning that they are relatively survivable. However, Portland's ready-use shell rooms are directly below the turrets and thinly-protected, meaning that they can be detonated by enemy shells and cause severe damage. Its main turrets have only 63 mm of armour on the front and even less on the sides, while its secondary armament is exposed and prone to shrapnel damage. All of these factors combined make for a vessel that can be quickly disabled and ravaged by lower caliber fast reloading cannons (Atlantas, Clevelands, and Brooklyns in particular are especially dangerous to the Portland), and it must be played cautiously. Portland has a crew of 1,033 crew members, which is about average for a cruiser; the ship's four engines are placed symmetrically in groups of two, meaning that a well-placed shot can knock out at least two engines.

Mobility

Speedforward / back

AB70 / 21 km/h

RB60 / 18 km/h

USS Portland, as a cruiser, reaches a top speed of 32.4 kn. This is similar to most other United States Navy heavy cruisers, being fractionally slower than the later USS Pittsburgh for example. This speed will allow captains of Portland to keep pace or slightly surpass other nation's cruisers, though it will be outpaced by light cruisers and destroyers. This speed allows the Portland to take objectives, though it may not be recommended to close the distance, instead using the floatplanes to capture and keeping range from enemy vessels. Portland's rudder takes approximately 3 seconds to respond at flank speed, and the speed falls to 23 kn while in a sustained turn. Portland takes approximately 40 seconds to accelerate to flank speed, and 1 minute to come to a halt. Captains should be aware that USS Portland has a wide turning circle, and should give any obstructions a wide berth, as she will be unable to quickly respond to avoid collisions.

Armament

Primary armament

3 х Turret3 x 8 inch/55 Mark 9 cannon

Ammunition450 rounds

Vertical guidance-10° / 41°

The Portland carries a main armament of nine 8"/55 Mk.9 guns in three triple turrets, two fore and one aft. These guns are the standard armament for American heavy cruisers, and pack an impressive punch. The guns have good ballistics, and can access four shell types: Mk.14 Common, Mk.19 APCBC, Mk.25 HC and Mk.17 SP Common. Of these shells, the Mk.17 Special Common shell is most effective against cruisers, as it has a great explosive mass and enough penetration for most cruiser main armour belts. The Mk.19 APCBC shell can be used against heavily-armoured targets, but has a relatively small explosive mass of 1.65 kg. Finally, the HC shell, with almost 10 kg of explosive filler, is highly effective against destroyers and unarmoured vessels. The exception is when facing against American destroyers such as the USS Moffett, in which case their extensive anti-fragmentation armour makes them extremely (some would say unreasonably) resilient to HE nose-fused shells. When facing them it is best to use the Special Common shells to try and deal internal damage.

However, the guns have two main drawbacks. Firstly, they have the slowest reload speed of any 8-inch gun, with a fire rate of just three rounds per minute (20-second gun reload). This means that they fire much slower than their contemporaries, which typically have a fire rate of five rounds per minute (12-second reload). As well, the guns have the slowest horizontal turret rotation speed of any heavy cruiser, at just 3.1 degrees/second (comparatively, the Admiral Hipper's guns rotate at 6.8 degrees/second).

Secondary armament

8 х Turret5 inch/25 Mk.13 AA cannon

Ammunition200 rounds

USS Portland mounts a secondary battery consisting of 8 x single mount 5-inch/25 Mk.13 anti-aircraft guns. These are mounted 4 port and 4 starboard amidships, slightly behind the second funnel. These cannons were, unlike the 5-inch/38, purpose-built for anti-aircraft duty. Therefore they have access to just two shell types - Mk.36 AAC (HE-TF) and Mk.28 AAC (HE-VT), with no anti-surface rounds. The former is a time-fuse shell (meaning that the fuse is set by the crew before the weapon is fired, higher crew skills greatly help with the accuracy of the fusing), while the latter is a proximity fuse shell that explodes automatically within a 23 m radius around aircraft. Both shells are ineffective against armoured targets, having ~35 and ~36 mm of penetration respectively. However, they can be used against lightly armoured targets such as destroyers and patrol ships, destroying lightly armoured sections of heavier ships such as AA mounts and the superstructure, and of course the aircraft they were designed for. The HE-VT is the recommended shell, as it is both more reliable at downing planes and has more filler; this of course does more damage, both to enemy air and surface targets.

The guns themselves are relatively good at short-range defence, being capable of firing at 20 rounds per minute (3-second reload). As well, they have very good vertical and horizontal firing angles. The guns, as a 25 calibre weapon, have a lower velocity than the 38 calibre, with a velocity of 657 m/s, which may take some adjusting to.

Due to the lacklustre protection for the secondary battery, captains are advised to avoid repairing them until they are needed for defense, to avoid crew being drained considerably.

Portland carries four quadruple 1.1 inch "Chicago Pianos". The 1.1 inch/75 Mk.1 gun, otherwise known as the "Chicago Piano" (because it was the size of a baby grand-piano), was the standard anti-aircraft armament for most American ships prior to the introduction of the 40 mm Bofors cannon. These guns are mediocre at best; though they have a good fire rate (similar to the AN-M2 Browning), they aren't too effective at dealing damage, and also jam rather quickly. As well, take note that the gun doesn't have ammunition options.

Portland also carries twelve single 20 mm Oerlikon cannons. The 20 mm Oerlikon Cannon was the standard light anti-aircraft gun for several nations, including the United States, and replaced the prior AN-M2 Browning machine gun. This weapon is an effective short-range AA gun, and has great firing angles. The gun lacks belt options, but the loaded ammunition is still quite effective against light targets. As well, the guns fire from a drum magazine that will need to be reloaded. Because of the magazine design, the gun will not jam with continuous fire.

Scout plane

Located amidships are two catapults with one SOC-1 scout plane each which provide unique offensive and defensive abilities, expanding tactical options. Ship-launched scout planes fly just like regular tree units but lack munition choices and cockpit views. Alongside the typical abilities of strafing, dropping 2 x 100 lb bombs, and capping zones, the SOC-1 and other scout planes have the added ability to lay down smoke cover (up to 3 times). Captains will be wise to remember to utilise the aircraft and consider when best to use it, for example to cap a point early or late in the match, to create a smoke screen to stymie enemy bombardment and repair, to attack enemy units directly, or perhaps something completely new! With two scout planes one can risk a cap attempt at the beginning of the match, saving the second for any opportunity that presents itself.

Usage in battles

USS Portland isn't the easiest ship to play, especially given that it faces battleships often (which completely outclass it in every aspect except anti-aircraft protection) and many cruisers too (such as USS Brooklyn and USS Helena) which outclass it in terms of firepower. As such, the ship needs to be played carefully in order to succeed in battle.

Firstly, Portland's main battery is quite mediocre. The nine 203 mm guns, placed in triple turrets, have an extremely weak reload speed of 17.1 seconds with a completely spaded crew, and 20+ seconds with a stock crew. This reload speed is uncompetitive against most other cruisers at the Portland's BR, and severely limits the ship's damage potential. Furthermore, Portland's guns are inaccurate - and that is, very inaccurate. These weapons have a lot of trouble hitting things reliably beyond ranges of 8 kilometres, making the ship hard to play at longer ranges. These constraints mean that Portland does a lot better at closer ranges, where its main battery can hit targets reliably.

Secondly, Portland is not that survivable. Though it does have a relatively large crew size for a heavy cruiser, Portland lacks heavy armour, especially on its citadel, which houses the massive engine block. The ship also has little protection on its first stage shell rooms, subpar protection for its main armament, and exposed secondaries, all of which result in a vessel that can be rapidly crippled by even concentrated destroyer fire. Because of these constraints, you should try to use ground cover as much as possible to preserve survivability. In maps such as South Kvarken, with plenty of island covers, stay behind islands wherever possible. In open maps such as the conquest maps, your only hope will be to stay behind the front lines, and hope that enemies don't target you.

Finally, note that Portland does not have great anti-aircraft defence. While the ship does get access to several 28 mm "Chicago Piano" and 20 mm Oerlikon anti-aircraft gun mounts, these weapons lack range and power, limiting their effectiveness to ranges of less than 2.5 kilometres. Indeed, the ship does carry eight 127 mm Mk 25 guns, capable of firing AA-VT (proximity fuse) ammunition, but these weapons are not capable of firing fast enough to be able to destroy faster incoming aircraft. Because of this, you should try to stay with allied ships, particularly ships with great anti-aircraft protection. This will help ensure that your ship will stay safe from enemy aircraft.

Pros and cons

Pros:

• Improved armour protection from HE shrapnel compared to the Brooklyn
• Main guns hit relatively hard, being of a large calibre
• Thicker armour over main magazines than the Brooklyn
• Above average crew count
• Relatively good anti-aircraft protection for a pre-war American heavy cruiser
• Two scout seaplanes.

Cons:

• Long reload compared to most of its competition with minimum reload at 17.1 s
• Poor shell selection with primarily inter-war shells
• No torpedo armament
• Though strong among American CAs, anti-aircraft armament lacks hitting power and range making it relatively ineffective

History

The Portland-class cruisers were the third heavy cruiser design that the Americans produced in the interwar years, following the Northampton-class. There were only two ships in this class, the USS Portland (CA-33) and the USS Indianapolis (CA-35). Interestingly the Portland-class was originally planned to be a light cruiser design, being re-designated as heavy cruisers only after the hulls had been laid down in 1931.

Ships of the class were propelled by 4 screws, powered at 107,000 horsepower. This gave the ship a fairly standard top speed of 32 knots and a cruising range of 10,000 nautical miles.

Firepower was provided from 3 triple 8" guns in Mk. 14 turrets. This design was carried over from the previous Northampton class. These 280 ton turrets allowed a maximum of 41 degrees of elevation and 5 degrees of depression. The turrets were used in conjunction with the Mk.34 fire director system by, at the latest, 1945.
