Bluewater fleet research in War Thunder

Bluewater is the large-ship navy path: destroyers, cruisers, and capital ships that fight in open-sea matchmaking. This hub collects nation research boosts for those trees so you can order a main-line farm between your current and target Battle Rating.

Bluewater lines run longer than coastal trees and climb into higher ranks. Use the slider to buy only the BR window you need — early destroyer stretch, mid-tier cruisers, or the push toward top bluewater brackets — instead of guessing a one-size package.

Nations available here

Seven country cards match the usual bluewater offerings: USA, Germany, USSR, Great Britain, Japan, Italy, and France. China, Sweden, and Israel are not listed in this hub because those navy products are not offered as separate bluewater research SKUs here.

Bluewater vs coastal

If you play small ships and coastal forces (patrol boats, early coastal ranks), open Coastal Fleet Research instead. Mixing the two trees in one order is not how these cards work — pick the fleet type that matches the vehicles you want unlocked.

  • Large ships / open ocean → stay on this page and choose a nation card.
  • Coastal / shallow-water line → Coastal Fleet Research.
  • Flexible RP only → Research Points Farm.

Ordering flow

Open a nation, set current and target BR, review vehicle-info and priority options, then checkout. Completion uses account sharing as stated on the product. For ground or air trees, switch to Army or Aviation research hubs.
