Unlocking Experimental Ship Modules in Starfield

Experimental ship modules represent the pinnacle of customization in Starfield, offering players access to high-performance components that elevate spacecraft capabilities. These advanced parts become available after progressing through the Starship Design skill tree, enabling more sophisticated vessel designs for exploration, combat, and cargo hauling.

Mastering the Starship Design Skill Tree

The foundation for acquiring experimental modules lies in the Starship Design skill, found in the Tech skill tree. This perk governs the complexity and quality of ship components you can install. Each rank unlocks progressively better modules, with Rank 4 specifically granting access to experimental variants.

To advance through the ranks, players must invest skill points and meet installation requirements:

• Rank 1: Install 1 unique module.
• Rank 2: Install 3 additional unique modules.
• Rank 3: Install 10 more unique modules.
• Rank 4: Install 30 unique modules total.

These modules can be temporary; purchase, install, then remove them without significant loss, as they retain low resale value. This progression encourages experimentation with ship building early on.

Finding the Right Ship Services Technicians

Once unlocked, experimental modules appear in the inventories of Ship Services Technicians scattered across the Settled Systems. Not all vendors stock them—availability depends on location, faction affiliation, and your player level. Higher levels expand inventory options, particularly for reactors, engines, and weapons.

Key locations include:

• Crimson Fleet’s Key station in the Kryx system for scan jammers and stealth modules.
• Red Mile in the Porrima system for specialized combat parts.
• Outpost landing pads with Ship Builders for convenient access to standard and some experimental stock.

Visit multiple technicians to compile a complete set, as inventories refresh with travel and time.

Brand-Specific Modules and Headquarters

Beyond generic vendors, manufacturer headquarters offer exclusive modules with unique aesthetics and stats. These branded parts, unavailable at standard technicians, define your ship’s visual style and performance niche.

These HQs stock modules like oversized hubs, two-floor cockpits, and faction-themed weapons, enhancing both form and function.

Complete List of Experimental Modules

Experimental modules span all categories, providing superior power, efficiency, or capacity. Here’s a categorized breakdown:

Engines

• White Dwarf 3015 Engine: High thrust for agile maneuvers.
• SA-4330 Engine: Balanced speed and fuel efficiency.

Fuel Tanks

• 900T He3 Tank: Massive helium-3 storage.
• M50 Ulysses He3 Tank: Compact yet high-capacity.

Reactors

• Tokamak X-120S Reactor: Extreme power output for Class C modules.

Other categories like shields, weapons, and structural frames follow similar patterns, with experimentals offering top-tier stats once unlocked.

Ship Building Fundamentals and Rules

Building with experimental modules requires understanding core mechanics to avoid errors. Reactors dictate module class limits—a B-class reactor supports only A or B modules, not C. Balance mass, integrity, and power draw to prevent warnings.

Key rules include:

• Modules must match size and type slots.
• Total crew capacity aligns with habitats.
• Grav drive fuel scales with jump range.

Upgrading involves direct swaps; for full redesigns, use the Ship Builder interface at technicians or outposts.

Proven Strategies for Rapid Unlocking

To efficiently reach Rank 4, commandeer enemy ships during ambushes. Disable spacers, Crimson Fleet, or Va’ruun vessels, board, register, and swap modules repeatedly on this ‘experimental ship.’ This minimizes costs while fulfilling unique installation quotas.

Combine with research labs for additional unlocks, as ship mods parallel weapon attachments. Player level influences vendor stock, so explore progressively.

Optimizing Your Dream Ship

With experimentals in hand, prioritize builds:

• Combat: Pair high-output reactors with Deimos weapons and shields.
• Exploration: Nova Galactic engines and fuel tanks for long jumps.
• Cargo: HopeTech structs with massive holds.

Test configurations in safe space before committing credits. Outpost Ship Builders allow iteration without travel.

Common Pitfalls and Troubleshooting

Players often hit barriers like class mismatches or insufficient power. Solution: Upgrade reactor first. Vendor stock variability? Level up and cycle locations. Perks like Piloting expand class access beyond basics.

FAQs

Q: Do experimental modules cost more?
A: Yes, but their performance justifies the investment for endgame ships.

Q: Can I sell unused modules profitably?
A: No, resale is low; treat them as progression tools.

Q: What’s the highest ship class?
A: Class C, unlocked via Piloting skill and high-level reactors.

Q: Are there limits on module stacking?
A: Yes, governed by ship integrity and balance rules.

Q: How do brands affect gameplay?
A: Primarily aesthetics and minor stat tweaks; functionality is universal.
