Spaceship Building Blocks & Sci-Fi Starfighter Kits
Spaceship building blocks are where the space collection leaves the launch pad behind and heads into fiction. This collection gathers nine sci-fi inspired spaceship kits for adults — fan-designed starfighters, carriers and freighters built as display models — from makers including BaKa, Gobricks, Mould King, KBOX, Reobrix and Jiestar. Every set uses ABS bricks compatible with the major building brick systems and comes with numbered bags and illustrated instructions.
Sci-fi starfighter and capital ship building kits
Most of the fleet is built at 1:40 scale, so the ships sit together on one shelf. The Interstellar Starfighter by BaKa is an advanced 10–18 hour build, while the Orbital Command Destroyer Starship by Gobricks and the Republic Attack Carrier by Mould King are intermediate 5–10 hour projects. The Galaxy Freighter Ultimate with Lighting by KBOX adds light to the display.

Are these spaceship building kits official film merchandise?
Are these spaceship building kits official film merchandise?
No. The ships in this collection are fan designs inspired by science-fiction films and series, created by brick makers such as BaKa, Gobricks, Mould King and KBOX. They are not licensed products. What they share with the screen is the ambition: large display builds, most at 1:40 scale, designed to be studied up close.
What scale are the sci-fi spaceship building kits?
What scale are the sci-fi spaceship building kits?
Four ships share 1:40 scale: the Interstellar Starfighter, Orbital Command Destroyer Starship, Republic Attack Carrier and Galaxy Freighter Ultimate with Lighting, so they display as a coherent fleet. The Planet Express Ship is close behind at 1:45, and the Reobrix Star Destroyer 3D Painting is a wall-mounted piece rather than a scale model.
Which starfighter building kit is the most challenging?
Which starfighter building kit is the most challenging?
The Star Destroyer 3D Painting by Reobrix is tagged expert and takes 18 hours or more. Among the free-standing ships, the Interstellar Starfighter by BaKa is the toughest, an advanced 10–18 hour build at 1:40. The Jiestar Yamato-class Battleship is also rated advanced if you want a large capital ship.
Does any spaceship kit come with lights?
Does any spaceship kit come with lights?
Yes, the Galaxy Freighter Ultimate with Lighting by KBOX includes lighting, as its title says, making it the natural centerpiece of a dimmed display shelf. The other ships are static display builds. If you want models that move rather than glow, look at our remote control building kits across other themes.
Which spaceship kit is best for a first sci-fi build?
Which spaceship kit is best for a first sci-fi build?
The Planet Express Ship by Brick Craft is an easy 2–5 hour build at 1:45 and a relaxed introduction. From there, step up to an intermediate 5–10 hour project such as the Orbital Command Destroyer Starship by Gobricks or the Republic Attack Carrier by Mould King. Our buying guide compares the makers.
