How it Works: Upgrades. 30 Jun 2020
Icon_12.png
A player earns access to Upgrades at Account Level 9, allowing him to customize and improve each ship's performance to suit his play style. Ships of different tiers have access to different upgrades, described by the tables below. Certain upgrades are unique to certain ship types or nations, or even to a specific ship; check the Notes table columns for more detail.

Contents

Managing upgrades

One upgrade can be mounted in each slot. A particular upgrade can be mounted only in its appropriate slot.

An upgrade — mounted or demounted (in Inventory) — can be sold for half of its nominal purchase cost (some upgrades are not purchasable but obtained by other means). If the desired upgrade is available in Inventory, it may be mounted only from Inventory; an upgrade can be purchased only if one is not available in Inventory.

A mounted upgrade can be demounted to Inventory for 25 Doubloons, or sold. When selling a ship, all upgrades mounted on that ship must either be sold or demounted.

Base Upgrades

Base upgrades are purchased for credits. Some packages for purchase, challenge rewards, and mission rewards may also grant base upgrades.

  1. Research seems to show that the specific effects are as follows:
    • -50% to time for reaching full power. This is the time needed to "spool" the engines to full power in the direction the ship is traveling, and thus achieve maximum acceleration away from 0 knots. In other words, it increases the second derivative of speed (until the engines reach full power). It will not decrease the time it takes to reverse the engines to decelerate towards 0 knots. This effect is applied at all speeds.
    • Increases engine power when the ship starts moving. This increases the ship's acceleration away from 0 knots when between -6 and 6 knots displayed speed. In other words, it increases the first derivative of speed (within this speed band). It does not improve the ship's deceleration towards 0 knots.

Special Upgrades

A special upgrade is an upgrade that modifies the behavior of an associated consumable. These upgrades are obtained through the Armory, currently for Coal. Special upgrades mount and demount like other upgrades — only one upgrade at a time in a slot.

In the Upgrades section of the Modules page in Port, a small green cross Icon_modernization_special.png will appear on the slot where a special upgrade can be mounted when one is available in Inventory.

The ship must be able to equip the corresponding consumable in order to mount the upgrade.

A special upgrade does nothing if its corresponding consumable is not mounted. For instance, Defensive AA Fire Modification 1 (Increases the action time, and accelerates the reload speed of the Defensive AA Fire consumable.: +20% action time. / -10% cooldown time.) functions only if a Defensive AA Fire (While active, the damage per second of large caliber anti-aircraft guns is increased.) consumable is also mounted.

Tier V-X ships with the
Smoke Generator (While active, generates a smoke screen that blocks line-of-sight for both enemies and teammates.) or Crawling Smoke Generator (Generates a smoke screen that allows the ship to remain undetected at slow speeds.) consumable only.

Unique Upgrades ("Legendary" Upgrades)

Unique upgrades (often referred to as "Legendary upgrades") are upgrades for Tier X tech tree ships. The aim of these upgrades is to adjust the characteristics of a ship to make it perform better in a specific role or offer an alternative style of gameplay while keeping ships in balance with each other, even if one ship has the unique upgrade and another does not.

The upgrades mount and demount like other upgrades (only one upgrade in a slot at a time) in slots 5 or 6, depending on the ship. In the Upgrades section of the Modules page in Port, a small red cross Icon_modernization_unique.png will appear on the slot where a unique upgrade can be mounted when one is available in Inventory.

With Update 0.9.2, new mission chains for Unique Upgrades became unavailable. Uncompleted chains may continue until the end of 2020, at which time incomplete missions will be removed.
With Update 0.9.3, Unique Upgrades became obtainable through the Research Bureau. In subsequent updates, Unique Upgrades have been and will be changed, and new ones introduced.

To obtain a unique upgrade, each can be purchased for 19,200 Research Points in the Research Bureau section of the Armory.

Slot 5

Occupying Slot 5, these upgrades block the mounting of e.g. Concealment System Modification 1 (Reduces the detectability range of the ship and aircraft carrier's squadrons: -10% to detectability radius. / +5% to the dispersion of enemy shells fired at your ship.).

Slot 6

Notes

  1. 1.0 1.1 1.2 A 25% discount coupon is available once per month.
  2. From Update 0.9.5 note: Reduced the bonus to engine power. Now, with the unique upgrade and the “Propulsion Modification 1” upgrade, it’ll take the cruiser 21% more time to reach maximum forward speed, and it’ll take three times more time to reach maximum backward speed. The ship will still be gaining speed faster with these two upgrades compared to having just one of them. At the same time, the time it takes the ship to reach 1/2 and 3/4 of her speed remains almost the same. Deceleration is unaffected.
