About Navy Combat

Navy Combat is an independently developed naval warfare game that runs entirely in a web browser — no download, no plugin, no install. It is built with Three.js and TypeScript, and the whole thing is about one idea: make naval gunnery feel like it mattered.

What makes it different

Most browser games about ships are arcade shooters with a health bar. This one simulates the things that actually decided naval engagements:

Shells are real projectiles with gravity and air drag. At long range you fire at where the target will be in twenty seconds, and you watch the salvo fall.
Armour is modelled per region — belt, deck, bow, stern, turret, superstructure and an internal citadel box — and shells ricochet, overpenetrate, shatter or bite depending on the angle they arrive at. Angling your hull is a genuine defensive skill.
Ships die from flooding and fire as often as from raw damage, and damage control is a limited resource you have to spend at the right moment.
Hulls have inertia. A battleship takes an age to answer the helm; a destroyer is skittish. Collisions hurt, and ramming is a real if desperate tactic.

Scope

38 playable warships across five navies — see the full ship roster.
Battleships, heavy and light cruisers, destroyers, aircraft carriers and submarines, each with a distinct role rather than a stat reskin.
Sixteen mission types, from straight fleet actions to convoy raids, night battles, submarine hunts and boss raids — all of them explained on the game modes page.
A campaign of scripted missions, a ranked 1v1 ladder, and co-operative play against the AI.
A fleet-command RTS layer for large battles: an overhead view, selection, control groups, formations and orders — and you can drop into the helm of any ship you own at any time.
A built-in map editor, battle replays with shareable codes, ghost racing and a photo mode.
Weather and time of day that change how the battle plays: storms wreck long-range accuracy, night hides you until you open fire.

Technology

The renderer is Three.js with a custom Gerstner-wave ocean shader, procedurally generated ship models, and a physically flavoured lighting and post-processing chain. There are no downloaded art assets — every hull is generated geometry — and every sound is synthesised at runtime with the Web Audio API.

The simulation runs on a fixed 60 Hz timestep and is fully deterministic, which is what makes the lockstep multiplayer possible: both players run the same simulation from the same inputs and continuously verify that their worlds still agree. Determinism is strict enough that the simulation is not permitted to read the system clock, use the ordinary random number generator, or even call the browser's own trigonometric functions, because different browser engines round them differently and that is enough to make two clients disagree.

The backend is a Cloudflare Worker handling matchmaking relay, the ranked ladder and optional cloud saves. Everything else runs on your machine.

Free to play

The game is free. It is supported by advertising, plus an optional full edition that adds cosmetic camouflage schemes, the carrier hulls and progression boosts. Competitive ranked matches use stock ships with every bonus disabled, so paying never buys a combat advantage. See the Terms for details.
