The second main advancement in the second Death Star battlestation was the improvement of its superlaser. The new system also took advantage of new highly-advanced protections and safe-guards that would seal the small exhaust ports in the event of any unexpected excess of heat or energy. Instead of venting gases out of a single port, millions of millimeter-wide exhaust ports were scattered over the surface of the station, each of which propelled a small amount of the excess heat and gases into the vacuum. This was greatly improved, from a defensive standpoint, in the new revision. The first major change made in this redesign was the elimination of the two-meter-wide thermal exhaust port that was used to ignite a chain reaction in the main reactor of the first Death Star, destroying it. The most important revisions to the Death Star design made by Lemelisk were made to take into account and eradicate the technical flaws of the original battlestation which had enabled it to be destroyed during the Battle of Yavin. In the newest version, he added thousands of turbolasers while removing any external weaknesses.

Lemelisk was executed for the design flaws in the final version of the destroyed Death Star I, but was cloned by Emperor Palpatine in order to redesign the superweapon, eliminating the flaws of the former battlestation. The second iteration of the battlestation was also designed by engineer Bevel Lemelisk, the original Death Star's designer. If completed, the planetoid would have likely boasted a hyperdrive system similar to the original, comprising 123 (or more, given the larger size) individual generators. The newest incarnation of this dreaded superweapon, however, had a monstrous diameter of over 900 kilometers, demonstrating the intellectual and physical evolution of the Death Star I. Like its predecessor, the Death Star II was made of quadanium steel and equally divided into two hemispheres, which were in turn subdivided into 12 zones.
