Navy War is a Roblox tycoon-style PvP game where you build a naval base from scratch, grow your economy, and assemble a fleet of warships to battle other players at sea. You can unlock destroyers, cruisers, battleships, submarines, and aircraft carriers as your base develops. This guide covers how to get started, where to spend your money first, how to use the research tree to reach stronger ships faster, and how territories and admirals fit into the bigger picture.

[UPD] Navy War
01
What you start with after the tutorial
Check
In shortYour three starter assets give you a working foundation, but two of them are only temporary.
When you finish the tutorial, your base already has a small set of buildings placed for you.
One Patrol Boat spawn point is in place, giving you basic sea defense from the start.
Two Fishing Huts are running, producing food and a small passive incomethey can be deleted or replaced whenever you're ready.
Two Fish Farms are up and producing, but plan to phase them out in favour of better production buildings as you growFish Farms yield poor return per worker.
In shortPouring money into the economy before the military is the fastest path to growth in the early game.
These traps are easy to fall into because they look like progress. Each one eats into the cash you need for economic growth.
Worth watching out for
Spending big on military units before mid-game wastes resourcesthe payoff is too small to matter at that stage. Stick with lean structural defenses like Guard Posts, which have higher base health than Naval Yards.
Buying high-tier factories right away is too costlycheaper options like Brick Factories and Copper Mines do the same job of generating cash flow at a fraction of the price. Copper Mines employ only 2 civilians, so you can build several without hitting your population cap.
Building more than two Workshops early burns money you need for factories and housingeach costs 15,000 Cash and one or two is enough to keep construction moving.
Choosing a Submarine Dock over a Helipad early on is riskySubmarine Docks are countered the moment an opponent fields aircraft, while Helipads offer broader long-term combat utility.

In shortLow-civilian-cost factories let you spam production without hitting your population cap too fast.
Every factory produces 3 units of its resource every 10 seconds. The key difference early on is build cost and how many civilians each one ties up.
Factory
Build Cost
Civilians Used
Why it helps early
Copper Mine
3,500 Cash
2
Lowest civilian cost — spam-friendly
Brick Factory
15,000 Cash
4
Strong output relative to price
Oil Rig
1,250 Cash
3
Cheap entry, steady early returns
Solar Farm
25,000 Cash
3
Good value into mid game
Petrol Factory
10,000 Cash
3
Lucrative but has a large plot footprint — plan layout carefully
05
Three limits that block expansion
Summary
In shortIf cash is not the problem, one of these three caps is what is stopping you.
The bottom-right of the screen shows three separate counters. When you have enough money but still cannot build or deploy, check which counter is full before doing anything else.
Builders controls how many buildings can be constructed at the same time; add Workshops or research Builder upgrades to raise it.
Navy controls fleet size; building more naval structures or unlocking research nodes raises this cap.
Civilians controls your workforce; build more housing or unlock population research nodes to raise the limit.
06
Research tree priorities
Step
In shortStart with economic and population nodes so that every military unlock later costs you less effort to reach.
The research tree is laid out as a honeycomb hex grid split into three main branches: Civilian, Economy, and Military. Economic and population nodes should come first. Unlocking them speeds up your resource income, which makes high-tier military tech like Nuclear Engine (5,000,000 Cash, 6 hours) and Plasma Drive (5,000,000,000 Cash, 36 hours) far cheaper to reach. Balancing Automated Factories with Richer Quests under the Population branch keeps Cash and Gems coming in steadily.
More Civilians ($100,000 / 15 minutes)raises your island's workforce cap and opens up better quest rewards.
Builders I through Veach upgrade adds one construction slot; tiers I–IV cost Cash, and tier V costs 10,000 Gems, bringing the total to 10 slots.
Academy ($25,000 / 5 minutes) and Science NexusAcademy adds 10% research speed; Science Nexus stacks a further 30% on top across every branch.
Automated Factories ($5,000,000 / 3 hours)gives 15% faster farm production passively; pair it with Double Crops for a 0.5% chance to double each harvest cycle.
In shortKnow which currency each vendor wants before you spend, because Cash, Gems, and Robux are completely separate.
The Main Island Hub is where you buy, sell, recruit, and check market prices. Three currencies are in play, and mixing them up wastes resources.
Cash the green-note currency earned by selling production; used for most buildings and research.
Gems the blue-gem currency; used at the Premium Shop, Black Market, Admiral Recruitment, and certain research nodes.
Robux real-money currency; confirm any Robux purchase screen before proceeding.
General Shop sells base materials and construction blueprints for Cash.
Tradesman buys your surplus goods for instant Cash income.

Patrol Boat
The small starting vessel you receive after the tutorial, covering basic defense around your base.
Sailor House
A housing building that holds 3 civilians — more than the Fisherman's Hut (2 civilians).
Workshop

Science Nexus
A research node that increases research speed across all branches by 30%.
Offline Vault
A research unlock that boosts the rewards your base earns while you are not logged in by 200%.
Honeycomb grid
The hexagonal layout of the research tree, where each upgrade node connects to adjacent ones in a six-sided pattern.
Fish Port
A Black Market building costing 75 Gems that sends a ship to a controlled Oil Rig and duplicates 50% of your highest-producing farm; you can own a maximum of 2.
Admiral Residence

Guard Post
An early defensive structure with higher base health than a Naval Yard.
Black Market
A vendor on the Main Island Hub that sells special buildings and military equipment for Gems; stock rotates, so desired items are not always available.
Common questions
FAQ
Can I build a full fleet without spending Robux?
Base construction, economic growth, and fleet expansion are all accessible to free-to-play players.
Does it matter how I arrange buildings on my island?
Yes. Grouping farms and production buildings close together makes manual harvesting faster and keeps them inside the effect radius of Storage Centers and Worker Statues.
Which research branch should I open first?
Economic and population nodes should be the primary focus early on. Getting population upgrades, builder slots, and passive income nodes early makes every later unlock cheaper and faster to reach.
What is the point of capturing Oil Rigs?
Holding an Oil Rig lets you build a Fish Port, which automatically duplicates 50% of your highest-producing farm or factory output. Since you can build two Fish Ports, capturing an Oil Rig effectively lets you copy your best farm's full output for free.
