Battle Levels

Orion — British Tier IV battleship.

The first dreadnought ship in the world to carry 343 mm main guns; she was superior to all battleships built before her in terms of firepower. Besides this, in contrast to her British predecessors, the ship had reinforced side armor and a more advanced arrangement of artillery guns.

Player Opinion


HMS Orion is the Tier IV British battleship. Like other Tier IV battleships, Orion is fitted with large guns and thick armor at the cost of speed. Orion’s belt armor will not withstand broadside salvos, but it is sufficient at protecting the ship’s citadel when angled properly.

Orion is fitted with ten 343mm guns mounted in five turrets along her centerline; this turret arrangement allows all main battery guns to be fired simultaneously. The glacially slow turret traverse speed requires captains to plan ahead and begin rotating the weapons before entering an engagement. Additionally, Orion’s armor piercing shells will sometimes struggle to deal damage against other battleships. Captains should not be afraid to load high explosive shells in these situations. The high damage and fire chance on the HE shells makes them quite effective at damaging targets that the AP shells would normally not harm.

Orion also carries an impressive secondary armament for her tier. These small caliber guns can help fend off smaller targets who sail too close to the ship, but should not be the only defense against destroyers. Captains should prioritize any ship trying to come within range for a torpedo strike. Orion’s low torpedo damage reduction and hit point pool make her quite vulnerable to torpedoes.


  • High explosive shells have high fire chance and damage.
  • Long main battery range for a Tier IV battleship.
  • The ship can fire all ten guns without needing to expose much of her side.


  • Painfully slow turret traverse speed.
  • Health pool is on the low end for a Tier IV battleship.
  • Armor piercing shells may sometimes struggle to deal damage against enemy battleships.


Orion has three modules for captains to research: upgrades to her hull, propulsion, and gun fire control system. Captains should first research the upgraded hull for the increased health and maneuverability it provides, then invest experience gains in the gun fire control system upgrade for the extended main battery range before finally researching the propulsion upgrade.

Optimal Configuration


The recommended upgrades for Orion are as follows:

Commander Skills

For Level 1 skills, Expert Loader is the most useful option. This skill reduces the time needed to switch shell types if the main battery guns are already loaded. At Level 2, Expert Marksman is recommended to reduce the turret traverse time. High Alert and Jack of All Trades can also be taken to reduce the cooldown on the ship’s consumables. Superintendent is recommended at Level 3 for the extra charge of the Repair Party consumable it provides. Basics of Survivability is also recommended to reduce the time needed to repair fire, flooding, or module damage. Finally, for Level 4 skills, Concealment Expert is recommended to reduce the ship’s detection radius. Alternatively, captains can be trained with Fire Prevention to reduce the maximum number of fires on the ship and risk of fire.


Orion can equip the following consumables:


Type 1, 2, or 5 camouflage can be equipped for credits; Types 2 or 5 are recommended at a minimum to reduce the accuracy of incoming shells.


Orion can mount up to eight signal flags simultaneously. Captains looking to improve the ship’s survivability should mount India Delta (+20% to the amount of HP recovered when the Repair Party consumable is used.) and India Yankee (-20% to fire duration.). November Foxtrot (-5% reload time on all consumables.) can also improve survivability by reducing the cool down timers on the repair party and damage control party consumables. Sierra Mike (+5% to the ship's maximum speed.) is also recommended to increase the ship’s top speed. Lastly, economic and special flags can be mounted to increase the credit and experience gain per battle.
