The next Ultimate Collector Series set in Lego’s Star Wars collection focuses on one of the most beloved transport vehicles from the original trilogy: the AT-ST Walker. Slated to launch August 1, the 1,513-piece AT-ST model kit for adults is the cheapest member of the exclusive UCS club that you can find in stores today. You can preorder the Lego Star Wars: AT-ST Ultimate Collector Series set for $200 at Amazon.
$200 | Releases August 1
The All Terrain Scout Transport, better known as AT-ST, has been part of the Star Wars movie universe since The Empire Strikes Back. The 1,513-piece building set creates a detailed replica that looks quite similar to the AT-ST from Return of the Jedi.
The completed build measures 14.5 x 8.5 x 8.5 inches and has multiple interactive components, including an openable top hatch covering the cockpit, a rotating head, viewport shutters, and adjustable laser cannons. The AT-ST is well-known for its unique gait that resembles a chicken. Lego’s AT-ST has articulated legs, so you can move it around like a real chicken walker.
As an Ultimate Collector Series set, this AT-ST has a myriad of small details that you won’t find on transport walkers in Lego’s playsets. The spacious two-person cockpit has finer details that make it more aligned with its appearance in the movies. UCS builds also take a more thoughtful approach when it comes to layering and visible studs, and the promotional images reflect that here. The build process is generally more complex with an Ultimate Collector Series set, so the AT-ST and UCS sets are recommended for experienced builders ages 18 and up.
Like all UCS Star Wars builds and other large-scale display models, the AT-ST comes with an information plaque and a minifigure. Appropriately, the minifigure for this kit is an AT-ST Driver.

This is actually the second AT-ST in Lego’s Ultimate Collector Series. The first one released back in 2006 and has been retired for many years at this point. The upcoming model is far more detailed, partially because it has roughly 500 additional pieces, but also simply because Lego has upped its game over time.
As mentioned, the $200 AT-ST Walker is currently the most affordable set in the Star Wars Ultimate Collector Series. There are a few others available for under $250, including the TIE Interceptor Starfighter, X-Wing Starfighter, and Luke Skywalker’s Landspeeder.
The AT-ST is the second Ultimate Collector Series set of 2025. The first, Jango Fett’s Firespray-Class Starship, released on Star Wars Day and is available for $300 exclusively at the Lego Store.

More New Lego Star Wars Sets
The AT-ST Walker will release alongside several other Star Wars sets on August 1. Perhaps most notably, the K-2SO Security Droid from Andor Season 2 will be turned into an 845-piece display model. The Lego version of K-S20 is 16 inches tall and is available to preorder for $90 at Amazon.
If you need a new Lego Star Wars set to build while you wait for the new ones to arrive, Lego just released a pretty cool Battle Droid and vehicle set from The Phantom Menace. The Battle Droid with STAP Lego set costs $140 and comes with 1,088 pieces.
