If you’ve ever wanted to take your adventures underwater in Rust, the submarine is your go-to vehicle for stealth, underwater travel, and exploration.
Whether you’re hunting for sunken loot, ambushing unsuspecting swimmers, or just taking in the eerie beauty of the ocean floor, this guide will walk you through the controls, cost, and how to enter and operate submarines in Rust.
Types of Submarines in Rust
As of recent updates, there are two types of submarines available in the game:
- Solo Submarine – small, single-seater
- Duo Submarine – larger, fits two players and has a torpedo system
Both models are built for underwater travel and can submerge and surface at will. The duo version provides extra firepower, making it great for PvP on and under the waves.
How to Go Up in a Submarine in Rust
Entering a submarine is simple:
- Approach the sub from the side or front.
- Press E (interact key) to enter the seat.
- If it’s the Duo Submarine, you can choose between pilot and passenger seats.
Make sure you have Low Grade Fuel in your inventory — once inside, open the fuel hatch (look around inside the sub for the prompt) and deposit the fuel to power it.
How Much Do Rust Submarines Cost?
You can purchase submarines at fishing villages, which serve as safe zones for trading:
- Solo Submarine: 200 Scrap
- Duo Submarine (with torpedoes): 300 Scrap
Once purchased, the sub will appear in the water near the vendor. It’s important to note that subs do not come with fuel, so make sure you bring Low Grade Fuel (at least 50–100 to get started).
Submarine Controls – How to Drive a Submarine in Rust
The controls are similar to boats but with added options for depth control:
- W: Move forward
- S: Move backward
- A / D: Turn left/right
- Shift: Speed boost (uses more fuel)
- CTRL (Hold): Submerge
- Spacebar (Hold): Ascend / surface
- Mouse: Control pitch when underwater (look up/down to change angle)
Note: Watch your oxygen level when submerged. Subs have a limited internal oxygen supply. If you overstay underwater, you risk suffocating unless you surface or wear a diving tank.
Torpedoes (Duo Sub Only)
The Duo Submarine can fire torpedoes, which are especially useful in underwater combat.
Ammo: Crafted torpedoes (not cheap)
Fire: Aim and click the left mouse button (while in pilot seat)
Reload: Automatic, as long as you have torpedoes loaded in the storage
Tips for Submarine Use
- Use subs to dive wrecks or escape sea patrols.
- Be stealthy — enemies can hear the engine, so don’t idle near coastlines.
- Watch out for sharks and other submarines, especially if you’re carrying loot.
Summary
Submarines in Rust offer a fun and tactical new layer of gameplay, especially for aquatic missions or avoiding overland travel. Whether you go solo or team up in a torpedo-laden duo sub, mastering these underwater vehicles can give you the edge.
