Roon — German Tier IX cruiser.
Unlike her predecessor, the ship was larger in size and carried considerably reinforced AA armament. Moreover, she had more main battery guns that were arranged differently, resulting in the ship's artillery power being concentrated in the aft end.

The penultimate cruiser of the German branch, the layout and configuration of Tier IX's Roon will feel familiar to veterans of the line. Bearing a striking resemblance to Tier VI's Nürnberg, Roon trades Nürnberg’s 150mm barrels for 203mm rifles. Indeed, Roon bridges the gap between her immediate predecessor — Admiral Hipper — and Tier X's Hindenburg as an almost perfect melding of the two ships.
Roon initially carries over the same main battery guns as Hipper, but with an extra barrel in a very different configuration. Moving from double turrets to triples allows for more firepower to be concentrated into fewer turrets; this comes at the cost of losing one barrel forward in exchange for gaining two at the stern. Captains will need to return to the same style of play they developed in Königsberg and Nürnberg, hanging back at range for significant portions of a match and only closing when the situation favors them. Roon also has an upgrade module for the main battery that drops her reload time from 13 seconds to 10.5. This is a massive buff in her damage output and is worth spending Free experience on as soon as the ship is acquired, or, at a minimum, spending experience to unlock before Hull (B).
Once fully upgraded, Roon has an anti-aircraft suite that is a small step above Hipper’s Hull (C), and is only a few steps behind American counterpart Seattle. Even without Defensive AA Fire equipped, captains who invest in an Anti-Aircraft Build will notice a significant increase in their effectiveness against enemy aircraft. She easily has the largest health pool of all (non-Premium) Tier IX cruisers, and with access to Repair Party , Roon can take some punishment and hang in a fight far longer than Admiral Hipper veterans will believe. Like all of her German cruiser brethren since Tier IV, she has access to an improved version of Hydroacoustic Search that, when timed correctly, essentially makes her immune to long-range torpedo attacks.
Roon has a few small drawbacks. With only one quadruple-tube torpedo launcher per side, her torpedo armament is notably worse than that of the cruisers before and after her in the line. While this is not a crippling defect, it does mean that she must choose her brawling opportunities carefully and not over-commit. She is the slowest Tier IX cruiser: more than capable of supporting her team, but incapable of running enemy destroyers to ground when the situation calls for it (a problem further exacerbated by her turret layout). Her base surface detection is also quite high; something that veterans of the branch will be familiar with by now, but a handicap that must be worked around all the same.
Overall, Roon is a solid all-around cruiser with good firepower and above average anti-aircraft capabilities. She's a significant upgrade from Admiral Hipper and sets the table nicely for what captains can expect to find when they advance to Hindenburg.Pros:
- Strong armor-piercing damage.
- Excellent main battery performance, with quick reloads and high shell velocities.
- Armor is sufficient; turtleback scheme makes her resilient to citadels at close range, but leaves Roon vulnerable to plunging fire.
- Has access to the improved version of Hydroacoustic Search available only to German ships.
- Solid anti-aircraft suite.
- Quick turret traverse time helps lower her broadside exposure when firing the rear guns.
Cons:
- Limited torpedo armament.
- Below average HE shell damage.
- If her lone frontal turret gets knocked out, playing Roon well is difficult.
- Poor concealment.
- Slowest Tier IX cruiser.
Research
Availability of researchable upgrades for Roon is as follows:
- Main Battery: Upgrading Roon’s main battery module will increase her rate of fire and increase her turret traverse speed.
- Hull: Upgrade to Hull (B) for a significant boost to her health pool (+14%), a healthy increase in her anti-aircraft defenses, and improved rudder shift time. Research of this module unlocks progression to Hindenburg.
- Gun Fire Control System: Upgrade to FKS Typ 9 Mod. 2 for an extra 10% range on the main battery.
Optimal Configuration
Upgrades
The recommended upgrades for Roon are as follows:
- Slot 1: Main Armaments Modification 1 *
- Slot 2: Damage Control System Modification 1 *
- Slot 3: AA Guns Modification 1 *
- Slot 4: Steering Gears Modification 1
- Slot 5: Concealment System Modification 1 *
- Slot 6: Main Battery Modification 3 *
Virtually all builds of Roon find themselves mounting Steering Gears Modification 1 in Slot 4. After that, captains have some critical choices to make.
Main Armaments Modification 1 is the recommended pick for Slot 1, though captains who choose to equip Spotting Aircraft may wish to install Spotting Aircraft Modification 1 in this slot instead. Captains with access to either Hydroacoustic Search Modification 1 or Defensive AA Fire Modification 1 are encouraged to plug those in Slot 2 depending on which consumable they opt to equip. Concealment System Modification 1 is the most popular pick for Slot 5 in order to help curtail her large detection radius; combined with a captain with the Level 4 skill Concealment Expert, her detectability range drops under 11.0 km. Conversely, Steering Gears Modification 1 is a strong option in the same slot for captains who prefer quicker rudder response.
As the first ship of the branch with access to Slot 6, Roon offers captains some tantalizing options. The most popular is Main Battery Modification 3, which is a straight rate-of-fire buff to her main battery guns. Some captains prefer the additional range offered by Gun Fire Control System Modification 2 , while still others prefer Auxiliary Armaments Modification 2 to aid them in their quest to annihilate enemy aircraft.
The upgrade in Slot 3 is largely dependent on how captains intend to invest commander skill points on Roon and the role they want her to fulfill in a given game.
Generalist Build: The easy choice for Slot 3 is Aiming Systems Modification 1 , which improves her shell dispersion and provides a minor buff to her secondary battery. This is the recommended pick for captains who don't wish to specialize the ship in anti-aircraft defenses.
Anti-Aircraft Build: Roon’s AA suite can be made even more potent by equipping AA Guns Modification 1 in Slot 3, and maximized by assigning a captain with Basic and/or Advanced Firing Training. This pair of upgrades provides excellent anti-aircraft protection for herself and teammates when utilizing Defensive AA Fire . However, this does mean sacrificing the exceptional German Hydroacoustic Search and is a setup that is largely wasted in games without an aircraft carrier present.
Commander Skills
Roon prefers to hold opponents at arms' length, though she is quite well-equipped to close to point-blank range with enemy ships when the opportunity arises. High-tier German cruisers play — and handle — much like small battleships, and players will frequently find their commander skill choices echoing those popularly found on battleships: Priority Target at Level 1 and Adrenaline Rush at Level 2. Concealment Expert is also highly recommended at Level 4.
Level 3 is where captains are offered some customization in their build. Captains preferring the Anti-Aircraft Build will want to opt for Basic Firing Training. Those pursuing the Generalist Build are better off opting for Demolition Expert; Vigilance is also a decent choice.
Similarly to Hindenburg, Roon's HE penetration can be improved to 63mm with Inertia Fuse for HE Shells, allowing her to damage more well-armored battleships directly with her High Explosive rounds. While is is not as effective as it is on it's successor, due to 9 shells per volley instead of 12, it will still provide a respectable damage increase for an otherwise anemic HE shell.

Consumables
Roon can equip the following consumables:
- Slot 1: Damage Control Party
- Slot 2: Defensive AA Fire – 3 charges or Hydroacoustic Search – 3 charges
- Slot 3: Spotting Aircraft – 4 charges or Catapult Fighter – 3 charges
- Slot 4: Repair Party – 4 charges
The choice between Defensive AA Fire and Hydroacoustic Search in Slot 2 is captain's choice; those who have opted for an Anti-Aircraft Build commonly prefer Defensive AA Fire, but some captains stubbornly refuse to eschew the stellar German hydro in this slot despite the investment in AA defense. Roon is still well-capable of shooting down aircraft without Defensive AA Fire, but will not be able to screen her teammates from enemy bombers nearly as well without it.
Similarly, the choice between Spotting Aircraft and Catapult Fighter is not lightly made. The Catapult Fighter helps enhance her anti-aircraft defenses, while the Spotting Aircraft affords Roon captains windows where they can harass enemies at extreme ranges (when stacked with Gun Fire Control System Modification 2 , Roon has a mind-boggling 24.8 km main battery range for the duration of the Spotting Aircraft).
Signals
Sierra Mike () will help improve her average speed, while Anti-Aircraft Build captains will want to throw on November Echo Setteseven () as well. India X-Ray () and Victor Lima () are also recommended to increase the fire chance of her high explosive shells against angled cruisers and battleships. India Delta () should always be flown to maximize her Repair Party .
