Dossier: The History of AT-AT Walkers and UCS Engineering

Updated on 26 June 2026

The Structural Evolution of the All Terrain Armored Transport

The AT-AT™ walker stands as one of the most complex design challenges in the history of construction bricks. From the early simplistic versions to the crowning achievement of the UCS (Ultimate Collector Series) model under reference 75313, the quest for stability has dictated every innovation. For the AFOL community, this set represents a feat of engineering because it manages to maintain a 62 cm high structure on four articulated legs without collapsing under its own weight. The use of worm gears and internal locking mechanisms is a direct technical response to the laws of gravity.

Technical Measurements and Specs of the 75313 Model

The collector version commands respect with its massive dimensions that require a controlled display environment. Here are the major features of this replica.
  • Height : 62 cm of pure Imperial power
  • Length : 69 cm from the cockpit to the rear engines
  • Width : 24 cm at the central chassis level
  • Details : Massive GREEBLING on the flanks and engine blocks
As highlighted in our AT-AT display guide, such a high density of bricks exposes the ABS plastic to a risk of accelerated yellowing if it is not protected from UV rays. MyBrickGallery optical-grade acrylic acts as a sanctuary for your investment. By isolating your model, you ensure that every construction click remains an intact visual pride for decades to come. Your galactic hangar can be completed with other mythical pieces protected by the case for the Millennium Falcon.
