The Ship

Tier VII Coronel Bolognesi is a modernized Ceylon-class cruiser, and a close sister to the British cruiser Fiji. She has a reduced main battery armament in order to mount more AA defenses, and lacks the Smoke Generator carried by her British sister. Her Combat Instruction can be used to drastically reduce the cooldown time of her consumables. While she shares some similarities with Fiji, her weapons and consumables give her a different role in battle.

Coronel Bolognesi's hull only represents a minor improvement over her predecessor Almirante Cochrane. Her stock hull has less HP, and even her upgraded hull only provides a 700 HP increase over Almirante Cochrane. 31,400 HP is low for a Tier VII cruiser, although her Repair Party can increase her survivability. She is also a more visible target. Her detection range can be reduced to 10.1 km like Fiji, and although this is still over a kilometer worse than Almirante Cochrane, it is still better than many of her peers. With a rudder shift of 8.6 seconds and a small turning circle of 600 m, she is an agile ship. Despite her agility though, she has a fairly slow top speed of 31.5 knots. She will struggle to escape from an unfavorable position, and is unable to chase down most enemy ships.

Coronel Bolognesi carries a standard Damage Control Party , with an action time of 5 seconds and a 60 second cooldown. She has the choice between mounting a Defensive AA Fire  consumable or a Short-Range Hydro-Acoustic Search , both with four charges by default. Her Defensive AA Fire provides a 150% boost to continuous AA damage and a 400% increase to her flak for a 40 second duration.The Short-Range Hydroacoustic Search is similar to the one carried by British destroyers, with a 3 km detection range for both torpedoes and ships. Unlike the longer-lasting destroyer version, this is only active for 100 seconds. The stand out consumable in her arsenal is an improved Repair Party , which allows players to recover large amounts of health. It has four charges as standard and can repair up to 70% of penetration damage taken and an incredible 70% of citadel damage received. This allows players to recover up to 9,950 HP per charge, up to a total of 39,800 in the unlikely event that all four charges are used to their maximum effect. With the exception of her Damage Control Party, her consumables all have a 180 second cooldown between uses.

Coronel Bolognesi's consumables have a much longer cooldown than usual, but this can be reduced through the use of her Combat Instruction. To charge the instruction, players must fill the progress bar by obtaining main battery hits. When activated, it has an action time of 30 seconds, and reduces her consumable cooldown by 75% for the duration of the active period. This means that the 180 second cooldown can be reduced to 90 seconds, which is particularly useful for rapidly recovering large amounts of health before returning to battle.

Armor & Survivability

Coronel Bolognesi shares the same general armor scheme as Fiji. Her 114 mm thick citadel armor of 114 mm is fairly thick for a light cruiser and can bounce a surprising amount of shells when angled. Her 16 mm plating can bounce most cruiser AP within her matchmaking spread if angled correctly, but battleships and some larger cruisers are capable of overmatching her. Unfortunately, she has a rather long citadel which sits higher out of the water than Fiji, making it a more vulnerable target. Her armor is sufficient for fighting destroyers and cruisers, but even her improved heal will not be able to protect her from deletion if players are not paying attention. To add to the potential issues of her thin armor, Bolognesi has a small hit point pool. 31,400 hit points is only higher than Atlanta, Flint and Chumphon. As a result, she can easily find her hit points rapidly stripped away.

Armament

Coronel Bolognesi has a main battery of nine 152 mm guns in three triple turrets. They have a fairly short range of 15 km, and can only fire AP rounds. Her 7 second reload is fast for her caliber, and is only beaten by Munchen at Tier VII. Her rapid reload is held back by her small main battery size, as only Omono and Eendracht have a lower AP DPM among Tier VII light cruisers. With two-thirds of her firepower mounted at the front, she suffers less of a DPM reduction than most other Tier VII cruisers when engaging a target bow on, but her rearward DPM is much weaker. Additionally, her firing angles are rather limited. Attempting to bring all of her guns to bear will require showing a lot of broadside, particularly when attempting to shoot targets to the rear. Her potential AP salvo damage of 27,900 is one of the lowest in tier; even Atlanta can potentially cause more damage with a full broadside. To compensate for this, she has some of the best accuracy in her tier — with destroyer dispersion, she will land more shells on target if players can aim well.

Unlike the tech tree British light cruisers, Coronel Bolgnesi does not have a shorter fuse timer or arming threshold, although she does keep the same improved penetration angles. This means that players can expect more over penetrations on thinner targets like destroyers or superstructures, but they can expect more penetrations on larger ships. Her AP penetration is one of the highest among Tier VII light cruisers. She can reliably citadel any broadside Tier VII cruiser up to 10 km away. Although Bolognesi shares the same main guns as Fiji, she uses a modified shell with less drag. They will lose less velocity during flight, so her gunnery at long range is more comfortable, and they retain better armor penetration.

Coronel Bolognesi carries a triple torpedo launcher on each side with a range of 8 km and a speed of 65 knots. The small salvo size and inability to launch her weapons from stealth mean they are not a primary weapon. They are useful for finishing off battleships which stray too close or for launching around corners. But they lack the ability to sink most targets in one strike, and any attempt to do so against a vigilant enemy risks receiving serious damage in return.

Anti-Aircraft

Coronel Bolognesi has fairly weak long-range AA defenses, with only Munchen and Abruzzi having lower long-range DPS, although her 5.8 km range is greater than theirs. This also extends to her flak bursts, as she only creates two bursts per salvo. Instead, Bolognesi's AA is centered around her medium-range defenses, which consist of 40 mm mounts with a range of 3.5 km. Although she is unlikely to stop an attack, her AA can make repeated passes costly.

Anti-Submarine

Coronel Bolognesi has an airstrike with a 6 km range for her ASW attack. Each charge reloads in 30 seconds, and she can have up to two ready to launch. If needed, she can also use her Hydroacoustic Search to locate a submerged submarine at up to 2 km.

Battle Performance

Players will need to be cautious when playing Coronel Bolognesi. Her thin armor and small health pool mean that she is at risk of suffering a Devastating Strike if she overextends. Her relatively slow speed and lack of a smokescreen limit her options for disengaging when spotted, unless she has some island cover or a friendly smokescreen to duck inside. With her short main battery range and lack of HE, effective target selection is necessary to ensure a good impact on the battle. With her good concealment and rapid firing guns, Coronel Bolognesi can be well suited to supporting friendly destroyers. Her improved penetration angles mean she is able to successfully engage maneuvering destroyers, although players will often over-penetrate. Her rate of fire can still rapidly strip away a destroyer's health even if overpenetrations are taken into account. However, she is not well suited to hunting destroyers by herself as her Hydroacoustic Search range is too short to be an effective tool. It can be used if needed, but will require getting dangerously close if a destroyer has torpedoes ready to launch. Her guns have enough penetration to damage any light cruisers that are within range to threaten friendly destroyers, and can score citadel hits on most cruisers she will face. Enemy cruisers must make the choice between reducing their angle to Bolognesi and lowering their DPM, or bringing their full firepower to bear and risking numerous citadel hits.

Where possible, island cover should be used when engaging larger targets. Her low health pool and thin armor mean that she can be sunk in one or two salvos if caught in the open. Players will struggle to cause meaningful amounts of damage while kiting away from enemy ships. Although her guns reload quickly, she only has three guns to the rear, and the poor firing angles of her front turrets mean that unmasking them will both slow her down and reveal a lot of broadside. Her torpedoes also lack the range to effectively cover a retreat. Any targets that are within torpedo range will be well inside Bolognesi's detection range and close enough to reliably hit her. The lack of HE emphasizes this drawback, so Bolognesi needs assistance in sinking battleships unless she is able to ambush a damaged battleship and score multiple torpedo hits.

Coronel Bolognesi works best at medium to short range, where her rate of fire and accuracy can be used to rapidly deal with cruisers which threaten friendly destroyers. Her lack of HE rounds means that players should look to take up flanking positions where possible in order to minimize the effect of angling.
