LEGO Set 60446-1 – Modular Galactic Spaceship: Alternate Build Possibilities

The LEGO City 60446-1 Modular Galactic Spaceship is one of those rare sets that begs you to pull it apart and rebuild it in a dozen different directions. With its sleek hull panels, a generous supply of wedge plates, canopies, hinges, and detailed greebles, it’s a modular playground for sci-fi creativity. Out of the box, you get a versatile starship that feels right at home escorting cargo, scouting asteroid belts, or sprinting through hyperspace. But the real fun begins when you discover how far the community has pushed these parts: compact cruisers with reworked silhouettes, shuttle extensions that transform your docking routines, turret packs that flip the ship from courier to combat-ready, and aerodynamic wing sets that turn your build into a speed demon.

Because 60446 is already “modular,” most fan designs lean into that core idea—swap a nose cone, reconfigure the mid-section, bolt on wings, or dock a shuttle. You’ll find full alternates built only from this set, partial alternates that pair 60446 with another small set, and modifications that add a few extra parts for maximum effect. Each approach unlocks a different style of play: tighter swooshability, new mission profiles, and clever techniques that teach you more about part usage. Below you’ll find a curated list of community creations—complete with designers, direct links to instructions, and CDN image thumbnails for fast loading on your site. Whether you want a sleeker cruiser, a tougher gunship, or a utility rework, this set’s inventory can take you there.
