Navy War Codes (September 2026)

Navy War is a Roblox base-builder where you construct docks and shipyards, then send warships out to conquer rival islands. Codes hand out free Gems and Crystals that shorten the grind for upgrades and new ships.

Working Navy War codes

These codes are active right now. Redeem them before they get pulled, since expiration dates aren’t announced in advance.

DECORATIONS — 50 Crystals NEW
KRAKEN — 50 Crystals NEW
ADMIRALS — 50 Gems
DIAMONDZ — 25 Gems

How to redeem codes in Navy War

Codes are entered through the in-game shop rather than a separate codes button, so the exact menu matters.

Launch Navy War on Roblox and let your base finish loading before opening any menus.

Click the Shop button on the left side of the screen.

Type or paste a working code exactly as written into the “Enter a code here…” box. Codes are case-sensitive, so match the capitalization shown above.

Click Redeem to claim the reward.

You’ll know a code worked when your Gem or Crystal balance updates immediately inside the shop menu. If the balance doesn’t move, recheck the spelling and casing before trying again.

Expired Navy War codes

No Navy War codes have expired yet. Any code that stops working will be moved here once confirmed.

Where new codes get announced

New codes tend to show up around content updates and fleet milestones. The Fleet HQ Navy War Discord server is where the developers post them first, and it’s also where you can track future updates to the game itself.

You can also check the Navy War page on Roblox directly for any announcements tied to new updates.

Redeem DECORATIONS, KRAKEN, ADMIRALS, and DIAMONDZ while they’re live, and put the Gems and Crystals toward your next dock or shipyard upgrade before checking back for more.
