Spaarti cloning cylinder Spaarti cloning cylinders were devices used for the creation of personal clone armies by those wealthy and / or well - connected enough to acquire them . To create clones from Spaarti cylinders was the fastest known form of cloning . Kaminoan cloning had a single clone grown safely at maturity in ten years . With a Spaarti cloning cylinder , a fully - mature adult Human could be grown in a staggeringly quick one standard year . However , Kaminoan cloning was much more effective , for ten years of growing in constant learning and training resulted in creating perfect warriors despite the long wait . Spaarti clones did not receive any training , instead they had their personalities formed by a process known as " flash memory " , which involved writing the memories of another person to a fresh clone ' s brain . Spaarti clones grown in less than a full year had the dangerous side effect of possible clone madness . However , Thrawn discovered that using ysalamir i to cut off the clone ' s connection to the Force would enable the creation of the clone within 15 to 21 standard days . History . They were built by Spaarti Creations , on the planet Cartao . They seem to have their origins in Khommite cloning technology , which had for a millennium been developed to a level far surpassing that of the rest of the galaxy . Cloning cylinders were thought to have been destroyed during the Battle of Cartao , but many units survived . The Galactic Republic used Spaarti clones to complement the Kaminoan clone army . At the near end of the Clone Wars , all but a few were unaware that Supreme Chancellor Palpatine had secretly commissioned a second clone army , which differed from the Kamino - bred Fett clones in two primary ways : they were grown to maturity in roughly one year as opposed to ten years , and they were created on Centax - 2 instead of Kamino . Omega Squad noticed this , adding to their suspicions about Chancellor Palpatine ' s intentions . The clone troopers of the 14th Infantry Brigade were among the first generation of Spaarti - grown Fett clones and vanguard of what was to come in Palpatine ' s New Order . While the Spaarti Fett clones numbered in the billions , and were thus possibly far more numerous than the depleted numbers of their Kaminoan - bred Fett brethren , the Spaarti clones were given only flash - training on the basics of being a soldier , such as how to fire a rifle . When first sent into action , the clones of the 14th did not bother to take cover from enemy fire , and their weapons accuracy was surprisingly pitiful , as noted by the commandos of Omega Squad . Also , they were completely unaware of all things Mandalorian , thus indicating that the Mandalore culture was never introduced to the Spaarti clones . Ultimately , the clones of the 14th Infantry were a sign of a new breed of clones to come : the clone stormtrooper . While the amount of clone stormtroopers , from all genetic sources and not just the Fett template , was far greater than the GAR , clone soldiers bred for the Galactic Empire generally exhibited poor marksmanship and lacked in tactics . Their strategy basically involved charging towards the enemy , weapons blasting , until all targets were neutralized - regardless of clone casualties . They were even known to refuse to follow orders and fire on their own allies because of the clone madness . As a result , the Empire eventually abandoned the technology and pursued the process of recruiting troopers in more traditional ways . Emperor Palpatine also kept several private stores of these devices , which he used both to clone dark versions of powerful Jedi and to clone new vessels for his dark essence . Grand Admiral Thrawn discovered thousands of cylinders in the Emperor ' s secret storehouse in Mount Tantiss on Wayland and used them to create an army of clones to man his " Dreadnaught " fleet . Grappa the Hutt also used Spaarti cylinders as part of his plan with Black Sun to replace members of the Imperial Interim Ruling Council with clones .
