Naval Base

Naval Bases provide bonuses to a Clan and its members, depending on which structures the Clan has built. There are a variety of structures available, including options for increasing the experience gains in ships of each nation, reducing the service costs of specific ship classes, and providing a discount on purchase costs of specific ship tiers. Each of these structures is purchased using Oil.

Oil

Players in a Clan can earn Oil, a Clan-specific resource to spend on building structures that improve the clan Naval Base and which provide bonuses to Clan members. While Wargaming will also occasionally offer in-game missions that reward Oil, it is earned regularly through two primary methods:

• Each Container earned by a Clan member will add 10 Oil

to the Clan's stockpile. This bonus does not have a daily limit, and applies to regular Containers, Supercontainers, and any special Containers earned or purchased from the Premium Shop.
• Each victory in Clan Battles will add 30 Oil

to the Clan's stockpile. The maximum that can be earned is 90 Oil

per member per day.

Players in a clan pool their Oil

to build Structures that benefit all clan members.

Structures

While any member can view the list of structures and their bonuses, only clan members given the role of "Commander" and "Executive Officer" can build structures. A future "Builder" officer type is planned at some point. Ten (10) types of structures are ultimately planned, with five (5) available in the first version. Each structure type modifies one in-game parameter. Structures are marked with special flags in order to indicate which ship type a certain structure type affects. The Clan's "Builder" opens flags by spending Oil. Opened flags make the structure's features available for the group of ships indicated on the flag, and a structure's current flags are indicated on its icon. Clan buildings must build expansion 1 before they can build expansion 2 and expansion 2 before expansion 3 and so on.

Officers' Club

Naval Base 2.0 (Update 7.9) replaced the Headquarters facilities with the Officer's Club. The Officer's Club still allows a Clan to grow beyond the base cap of 30 members, just in 4 steps instead of the old 2 steps. The Oil cost for the 4 new expansions is the same as the 2 old expansions.

Building	Oil cost	Effect
Officers' Club, Expansion 1	5,000	Increases maximum number of clan members by 5 (to 35).
Officers' Club, Expansion 2	15,000	Increases maximum number of clan members by 40 and makes it possible to join Clan Battles in one more rating.
Officers' Club, Expansion 3	35,000	Increases maximum number of clan members to 45.
Officers' Club, Expansion 4	65,000	Increases maximum number of clan members to 50.

Research Center

Research Center facilities have been changed from Nation specific buildings to Tier specific expansions. You can increase the experience gains of Clan members in all ships by as much as +5% instead of the old nation specific bonus of +3%. The Research Centers bonus now applies to all ships in the game once you have purchased the first three expansions.

Research Center, Expansion 1	100	+2% XP per battle for Tier I-VI ships
Research Center, Expansion 2	400	+2% XP per battle for Tier VII-VIII ships

Dry Dock

Dry Dock facilities decrease Clan members' service cost of ships of the referenced tier by up to 15%. The Dry Dock replaced the old Dock that could only decrease the service cost of a ship by 10%.

Shipbuilding Yard

Shipbuilding Yard facilities replaced the old Shipyard. The Shipbuilding Yard decreases the credit cost of ships of a particular tier by up to 15% for Clan members. Any discounts on purchasing a ship will also apply to their sale; if a player buys and then sells the same ship while the 15% bonus is active, they will save 7.5% of the initial cost of the ship. If any other discount is active when the bonus is, they are not added together, but the larger one applies.
