Quick Answer

  • Your first freighter is free: claim it after winning a space battle rescue event. This event is unlocked by completing the Ghosts in the Machine story mission, after which it will trigger on your next warp to an inhabited system once the cooldown conditions are met.
  • Don't accept the first free freighter automatically if you want a specific design; you can decline and find a better one later.
  • S-class freighters require save-scumming a freighter rescue battle in a 3-star economy or outlaw system; expect many reloads.
  • Freighter class is permanent: you cannot upgrade a C-class freighter into an S-class.
  • The core upgrade currency is Salvaged Frigate Modules, earned primarily from derelict freighters and frigate expeditions.
  • Cargo Bulkheads expand inventory slots and come from derelict freighters, rescue-event rewards, and frigate expeditions.
  • S-class freighters have four supercharged technology slots (versus three for A-class, two for B-class, one for C-class). Place your best hyperdrive upgrade modules in them for maximum jump range.

Overview

Class and slots are what this guide is about, and they are the only things that matter mechanically. Hull family and size — Venator against Sentinel, two mid-sections against seven — are cosmetic, and the freighter types guide covers how to tell them apart.

Your freighter is among the most transformative assets in No Man's Sky. It serves as a mobile base, a fleet carrier for your frigate expeditions, a long-range warehouse, and, once upgraded, a warp-capable powerhouse that opens up the galaxy. Unlocking a great freighter early dramatically accelerates every other goal, from passive income to reaching the galaxy center.

Freighter Types Explained

System Freighters vs. Capital Freighters

Type Where Found Notes
System Freighter Drifting in any star system Smaller, functional, less impressive visually
Capital Freighter Freighter rescue battle events only Large Venator or Sentinel design; what most players want
Pirate Dreadnought Outlaw system rescue events Aggressive aesthetic, red lighting; stat equivalent to capital freighters

Capital freighters come in two visual families: Venator (swept-wing silhouette, three sub-types: Venator, Imperial, Resurgent) and Sentinel (blocky, symmetrical, three sub-types: Sentinel, Battleship, Dreadnought). Within the Sentinel family, sub-types scale in midsection size: the smallest has three midsection segments, the Battleship has five, and the largest variant (Dreadnought) sports seven midsection segments, making it a popular target for collectors.

The Pirate Dreadnought is mechanically equivalent to a capital freighter in terms of inventory and upgrade limits, but sports a distinct look and spawns specifically in outlaw systems.

Visual preference is personal, but class is everything. The exterior design of a capital freighter is cosmetic. Focus on locking in an S-class before worrying about the hull shape.

How to Get Your First Free Freighter

The game offers your first freighter for free, regardless of its class, when you rescue it from a pirate attack. Before this event can occur, you must complete the Ghosts in the Machine story mission. This quest explicitly triggers your first rescue battle and introduces freighters. After that, subsequent rescue events require at least three hours of unpaused game time and five warps since the previous event. Time spent in menus does not count toward this cooldown.

The critical rule: you can decline to claim any freighter. If you claim a freighter and already own one, you'll trade your current one in. So if you claim your first free C-class freighter, you're locked into that ship until you purchase or earn another. Many experienced players recommend declining the first rescue freighter if the design or class isn't what you want, then grinding for an S-class using the method below.

For a step-by-step breakdown of the initial claim process, see our free freighter guide.

How to Get an S-Class Freighter (Save-Scum Method)

S-class freighters don't have guaranteed spawns. You need to reload saves until one appears. Here's the process the community has refined:

Prerequisites

  1. Economy Scanner (purchase from Iteration: Hyperion on the Space Anomaly for Nanites, or find at tech merchants). This lets you see system economy ratings on the galaxy map.
  2. Conflict Scanner (helps locate high-conflict systems where battles trigger more readily).
  3. A budget of roughly 150–200 million Units to purchase an S-class, unless it's your free first freighter.
  4. Make sure your Space Combat difficulty is not set to None: battles won't trigger otherwise.
  5. You need at least two prior rescue events before capital freighters begin appearing.

Spawn Rates by System Type

System Type Approximate S-Class Rate
Wealthy (3-star economy) ~2%
Outlaw ~5% (but may roll A-class stats)

Wealthy systems labeled "Opulent," "Booming," "Affluent," or "Flourishing" are the community standard for hunting because their S-class spawns have reliably good stat rolls.

Step-by-Step Process

  1. Cooldown check. A new rescue event spawns only after roughly three hours of unpaused game time plus five warps since your last event. Time in menus does not count.
  2. Lock a design you like. Warp through adjacent systems until a rescue event spawns a freighter with the visual design you want. Each system has a fixed design for its rescue events. Note the system.
  3. Save before grinding. Create a manual save by landing at a station and boarding/exiting your ship.
  4. Warp in and check the class. Defeat the pirates, then scan the freighter with your Analysis Visor before speaking to the captain. If the class isn't S, reload your manual save.
  5. Repeat. At a 2% rate, expect anywhere from 15 to 50+ reloads. Each cycle takes under two minutes once you've practiced it.
  6. Verify supercharged slots. Before finalizing the purchase, confirm the technology grid shows four supercharged slots. A known bug occasionally causes some S-class freighters to spawn with fewer than four.

Priority Upgrades: What to Install First

Once you own a freighter, upgrade progression revolves around two currencies: Salvaged Frigate Modules (for blueprints and technology) and Cargo Bulkheads (for inventory expansion).

Cargo Bulkheads — Expand Your Inventory

Cargo Bulkheads are curiosities that can be exchanged at the Upgrade Control terminal on your freighter's bridge to add new inventory slots. Sources:

  • Derelict Freighters (see below)
  • Rewards for winning freighter rescue battles after you already own a freighter (you receive a Cargo Bulkhead in addition to other rewards)
  • Frigate expedition rewards

Prioritize these early. More inventory slots make your freighter genuinely useful as a mobile warehouse.

Salvaged Frigate Modules — Unlock Technology

Salvaged Frigate Modules unlock freighter-specific blueprints and construction options at the Upgrade Control terminal. Key technologies to unlock:

Technology Why It Matters
Freighter Hyperdrive (multiple tiers) Dramatically extends jump range; six upgrade tiers available
Matter Beam Lets you remotely access freighter storage from anywhere in the same system
Fleet Command Rooms Required to run frigate expeditions simultaneously
Frigate Fuel Blueprint Unlocks Frigate Fuel crafting — essential for running a productive fleet

Six tiers of hyperdrive upgrades are available at the terminal. Unlocking all hyperdrive blueprints requires a significant number of Salvaged Frigate Modules: prioritize the first few tiers to unlock wormhole navigation, then work toward the higher tiers over time.

Where to Farm Salvaged Frigate Modules

  • Cargo pods at Outlaw stations: the fastest active method, and you can scope pods to read their contents before firing
  • Derelict Freighters: strong when the interior rolls chest-type crates rather than lockers
  • Frigate Expeditions: reliable passive income once your fleet is operational, with industrial missions paying the modules
  • Nexus Missions: the only guaranteed source, one module at a time
  • Crashed Freighter sites: found on planetary surfaces, and the pods refill after several real-world days

Each of these is worth doing under different circumstances, and the gap between the fastest and the slowest is large. The Salvaged Frigate Modules guide ranks them properly and covers which blueprint to unlock first with your early modules.

Supercharged Slots: Maximize Your Hyperdrive

S-class freighters have four supercharged slots in their technology grid. These slots are fixed in position and provide a substantial bonus to any technology installed in them. Place your highest-tier Freighter Hyperdrive upgrade modules in or adjacent to these slots. Technologies in supercharged slots still benefit from adjacency bonuses, so cluster your hyperdrive modules together with the best ones touching the supercharged positions.

The layout that actually wins is usually not the one that looks tidiest. Four supercharged slots and three hyperdrive modules means one supercharged slot is spare, and the correct answer is almost always to put the base Hyperdrive technology itself in that fourth slot rather than leaving it empty. Work it out on paper before you start dragging modules around: sketch your grid, mark the four purple squares, then place the three modules so that every one of them touches at least two others and as many as possible sit on purple. Moving an installed module costs nothing, so experiment freely, but check the hyperdrive range number in the ship stats panel after each rearrangement rather than trusting the layout to look right.

Derelict Freighters: Your Best Upgrade Source

Derelict Freighters are abandoned ships drifting in space that you board and explore. They are the single best sustained source of Cargo Bulkheads, Salvaged Frigate Modules, and high-value Upgrade Modules for your freighter.

How to find them:

  1. Purchase an Emergency Signal Scanner from the Scrap Dealer at any Space Station. The price starts low and increases with each purchase, resetting daily (prices cap at 30M Units per purchase). Alternatively, Iteration: Helios on the Space Anomaly hands out one free scanner per week.
  2. Activate the scanner and pulse-drive in any direction until it detects a signal.
  3. Land on the derelict freighter and explore through its rooms, defeating hazards and opening cargo pods.

Farming derelicts regularly is the fastest way to accumulate Cargo Bulkheads and keep your upgrade queue moving.

FAQ

Can I upgrade my freighter's class from C to S?

No. Freighter class is fixed at the time you claim the ship and cannot be changed. The only way to get an S-class freighter is to claim one that spawns as S-class. You cannot retrofit a lower-class freighter.

Is it worth waiting for an S-class, or should I just claim whatever I find?

It depends on your goals. An A-class freighter has three supercharged slots, only one fewer than the S-class's four, and with full upgrades will cover all practical needs. The extra supercharged slot on an S-class does meaningfully extend hyperdrive range and can speed up late-game galaxy travel. If you're planning to reach the galaxy center or push into endgame content, the S-class is worth the grind. Casual players can get by with a well-upgraded A-class.

Does the freighter's visual size affect its stats or inventory?

No. The visual size of a capital freighter (small, medium, or Dreadnought) is purely cosmetic. Stat ranges and maximum inventory are determined by class (C/B/A/S), not by how large the ship looks.

What is the Matter Beam and do I need it?

The Matter Beam lets you teleport items between your exosuit and your freighter's storage when your freighter is in the same star system. It's extremely convenient for players who use their freighter as a primary warehouse, and it's one of the first blueprints worth unlocking with Salvaged Frigate Modules.

How do I get more technology slots on my freighter?

Freighter technology slots are expanded using Cargo Bulkheads, which are exchanged at the Upgrade Control terminal on the bridge. Note that Storage Augmentations (used for starship inventory) do not apply to freighters. You need Cargo Bulkheads specifically.

Can I transfer my upgrades to a new freighter if I find a better one?

Technologies installed in a freighter cannot be moved to a new ship. If you claim a new freighter and trade in your old one, you will lose all the installed technology and need to rebuild from scratch. This is another reason to hold out for an S-class before investing heavily in upgrades.

Key Takeaways

  • Your first freighter is always free: but you must first complete the Ghosts in the Machine story mission to unlock rescue events, and you can (and often should) decline the first one to hunt for a better class.
  • Class is permanent. Grinding for an S-class up front saves a lot of frustration later.
  • Use the save-scum method in wealthy 3-star systems: lock a design you like, save manually, then reload until an S-class appears.
  • Confirm four supercharged slots before completing the purchase. A bug can reduce this count.
  • Cargo Bulkheads expand inventory; Salvaged Frigate Modules unlock technology blueprints. Bulkheads come primarily from derelict freighters; modules come fastest from Outlaw station cargo pods.
  • Unlock the Matter Beam early for remote inventory access, and prioritize Hyperdrive upgrades for longer warp range.
  • Place your best hyperdrive modules on or adjacent to your freighter's supercharged slots for the biggest jump range boost.
  • S-class freighters have four supercharged slots; A-class has three: the gap is real but small, making A-class a viable choice if you don't want to grind.
  • Once your freighter is set up, build Fleet Command Rooms and start running frigate expeditions. They're a major source of passive income and upgrade materials.
