I understand why the Empire would want to start using more than one genetic template to create clone troopers, but why did it start using non-clone troopers instead of just continuing the cloning program?

It seems that with cloning they were able to use a training program (and genetic manipulation) that gave them completely loyalty (other than when the Kaminoan rebellion, where the Kaminoans had sabotaged the training programs). Why stop using such troops and start using people that might question orders or aren't as easily controlled as clones were?

There were several reasons:

  • Fett Kaminoan clones were considered too risky due to Kaminoan rebellion (not due to their nature but their homogeneity)

  • Non-Kamino clones (e.g. Spaarti) were less stable

  • Clones were too expensive (and either too slow to mature or too unstable - take your pick). Getting a recruit is a lot cheaper than growing a clone.

    Hm, clones might actually take too long, too. From what we know, the first batch was in "production" over decades, with no or little speedup of maturation. This was no problem then because it was had to be done covertly and was planned long in advance. When the need for secrecy is gone, it should be way faster to recruit a lad with 18 and have him on active duty by 20.

    Can it be because they filmed IV, V, VI first and never mentioned clones and obviously were not clones. :D I am still curious why the director did not retake the scene "Trooper bumping his head upon entry". :D

    And, as shown in the modern military, it is possible to train in the characteristics of obedience that make clones so attractive- that's the real purpose of Boot Camp.

    @Sid They did mention a Clone War and that Obi-Wan fought in it under Leia adoptive father command. That is the whole reason he is their "only hope".

    @sid Episode IV definitely did reference the "Clone Wars", with Leia and Luke both mentioning it as a historical event. What is not present, however, are any mentions of any specific characters being clones. "The Clone Wars" was a thing, the identity or nature of those clones, or even the extent to which the name of the war was literal or figurative, was not. Dec 19, 2018 at 2:12

In Allegiance, stormtrooper protagonists suggest that the Emperor consciously stopped producing more clones, favoring regular humans.

I guess that while he would appreciate clones as useful tools, he would still consider them inferior to "pure" humans. He is a hopeless racist, after all.

Also, he has no need of them anymore. Jango Fett was a good template, but the main advantages of the clone army was short breeding and training cycles and absolute obedience. Once the Empire is firmly in place, the Emperor can take all the time he needs to train and brainwash regular troops. He has a vast pool of recruits, too, as opposed to when he was Chancellor.

Furthermore, I seem to remember that the clones did not fare too well when living longer. They were made to fight hard and die quickly, not to serve for decades.

(Copied from my answer here.)


After the Kamino uprising, the Emperor decided that an army of genetically identical soldiers was too susceptible to corruption. Future troopers would be cloned from a variety of templates. Though the 501st itself remained pure, gradually, the rest of the Imperial Army became more and more diverse. We never really got used to the new guys.

~ Retired clone trooper, Star Wars: Battlefront II

Although clones were considered obsolete by the emperor he still used them occasionally if he needed to quickly scare a rebellion back into submission. The Spaarti Cloning facilities on the moon of Coruscant (and I think there was another on Anaxes) could mass produce mature clones in less than a year. This is where most of the clones during the battle of Coruscant in Revenge of the Sith came from. A downside of this is they aged 20 times faster than normal humans and 10 times faster than Kaminoan clones.

  • Wookiepedia and Star Wars Battlefront II. I know the game probably isn't canon anymore but it still holds a small answer. Jan 31, 2016 at 0:07
  • In that case, +1. But maybe you should edit that comment into your answer.

The clone trooper program was discontinued for one of two reasons, as stated by the Imperial Brendol Hux in the Servants of the Empire series.

  1. Disease - Because they are exact clones, they are very weak when it comes to responding to genetic disease. If someone chose to use biological warfare to kill the, they'd die pretty easily.

  2. Inferiority - The Emperor thought of the clones as inferior beings, so he simply didn't want them to fight what "pure" people could fight.

  • "The Emperor thought of the clones as inferior beings". Well he was the one who commissioned them. Guess he saw them as a necessary evil in his rise to power? Apr 3, 2019 at 15:45

Jango was a good template, but after the Kaminoan uprising The Emperor decided that the clone army could rebel.

When the clones Captain Rex, and Commanders Wolfe and Gregor removed their inhibitor chips, this proved that other clones could do the same, so The Emperor decided to change the clones to be his private army and have humans form the body of his main army.
