Death Star Plans

Lore & Background

The Death Star was designed with a fatal weakness concealed within its massive structure. While the station is hundreds of kilometers wide and shaped like a spherical moon, the schematics revealed a specific ray-shielded particle exhaust vent leading straight from the surface to the reactor core. This flaw was discovered by Rebel forces after analyzing the stolen data. The construction of this weapon involved immense secrecy; in the animated series and prequel films, it is shown that General Grievous acquired an enormous kyber crystal on Utapau to power the superlaser. Later, under Orson Krennic's supervision, Galen Erso engineered the weapon, fusing kyber crystal shards to amplify energy into a beam powerful enough to destroy a planet. The plans were also connected to the Ghorman project in 2 BBY, where Imperial propaganda justified the mining of kalkite needed for reactor lenses. In Rogue One, the Death Star is referred to as Project Stardust before its true name is known to the Rebels.

In Their Own Story

The journey of the plans began with Princess Leia transporting the schematics on board the Tantive IV. To ensure their safety, she hid the data within R2-D2's memory banks just before stormtroopers boarded her ship. The droid carried these files across the galaxy until they reached the desert planet Tatooine. There, Luke Skywalker, Han Solo, Chewbacca, Obi-Wan Kenobi, C-3PO, and R2-D2 eventually made their way to the Death Star itself after being pulled aboard by a tractor beam. While escaping, Obi-Wan sacrificed himself in a duel with Darth Vader. Later, Luke returned as part of a fighter force to attack the station's only weak point. Using the coordinates from the stolen schematics, he launched his X-wing fighter's torpedoes into the exhaust vent. The impact triggered a catastrophic explosion that destroyed the station before it could annihilate the Rebel base on Yavin 4.

Reader's Guide

To destroy the Death Star, a pilot must utilize the specific coordinates found in the stolen schematics. The target is a ray-shielded particle exhaust vent, measuring only two meters wide, which leads directly into the reactor core. Deflector shields protect the rest of the station, but this vent remains exposed. The strategy requires a starfighter to navigate deep into the station's gravity well, specifically targeting the trench around the equator where the shield is absent. A proton torpedo must be fired precisely into this vent to impact the core and trigger a chain reaction capable of obliterating the entire 160-kilometer-wide battle station. This tactic was successfully executed by Luke Skywalker during the assault on Yavin 4.

Did You Know?

• The Death Star model was originally intended to be a perfect sphere, but a trench was added around the equator because two separate pieces of the physical model did not fit together.
• The buzzing sound counting down to the superlaser firing comes from the Flash Gordon serials.
• For Return of the Jedi, only the front side of the 137-centimeter (54 in) second Death Star model was completed; the image was flipped horizontally for the final film.
• The grid plan animation shown during the Rebel briefing was an actual computer-graphics simulation developed by Larry Cuba at the University of Illinois Chicago.
• In the series Andor, prisoners on Narkina 5 assembled fasteners revealed in a post-credits scene to be parts built for the superlaser dish.
