During the Clone Wars, Arkanian Microtechnologies was hired by Supreme Chancellor Palpatine to create a cheaper second clone army for the Galactic Republic. The project was confidential, and thus billions of credits were discreetly siphoned from various bank accounts in order to fund the construction of cloning centers on Centax-2, one of the moons of Coruscant. The new facilities were equipped with Spaarti cloning cylinders, which Arkanian Micro's scientists utilized to engineer full-grown clone soldiers in one standard year, as opposed to the Kaminoan method's ten-year waiting period. While the Spaarti method enabled the company to generate clones at a considerably faster rate than the Kaminoan-developed series of clone troopers, a one year growth period prevented Arkanian Micro's clone units from receiving the same training as their Kamino-bred counterparts. The company used flash pumping computers to download the basics of being a soldier into the subjects, but even the company admitted that the combat effectiveness of Spaarti clones was significantly lower than the troopers from Kamino. Such drawbacks concerned one of the scientists who monitored their development, but the Chancellor assured the Clone Master that the new clone troopers did not have to be as effective as their precursors.
In 19 BBY, the final year of the Clone Wars, the Grand Army of the Republic was a spent force. A third of the original clone troopers were dead while others were too injured to fight; what remained of the army was stretched thin across the Outer Rim Territories where the clones and their Jedi officers fought the Separatist droid forces in a series of grueling campaigns. By that time, Arkanian Microtechnologies deployed a vanguard of Spaarti clone troopers, officially commissioned as the 14th Infantry Brigade, into the war zone in order to test the effectiveness of their creations. Other clones from Centax-2 were integrated into existing military units such as the 501st Legion and Coruscant Guard. Chancellor Palpatine publicly revealed the existence of the new clone army during the Battle of Coruscant when the Separatists launched a surprise attack on the galactic capital. In the aftermath of the Republic's victory at Coruscant, Arkanian Micro's clone troopers were assimilated into the Grand Army, thus replenishing its depleted ranks.
After the Clone Wars, Arkanian Microtechnologies' services were retained by the Republic's successor state, the Galactic Empire. Under the reign of Emperor Palpatine, the New Order vastly augmented its military forces with more clone soldiers, all of whom were generated by Imperial-controlled Kaminoan and Arkanian Micro facilities. Shortly after Palpatine's rise to power was completed, the Emperor and his Sith apprentice Darth Vader, tasked Arkanian Microtechnologies with a commission to enginneer Force-sensitive clones, a task that had long since been dismissed as impossible. Using the genetic material of the Emperor's Hand Sa Cuis, Arkanian Micro scientists developed the Force-sensitive stormtroopers. Both Palpatine and Vader were impressed by them, and though they originally petitioned the company for more Force-wielding clones, the project was ultimately dismantled after the experimental stormtroopers rebelled against their creators due to the machinations of their Dark Jedi trainer, Sheyvan.
Arkanian Microtechnologies was still operational by 40 ABY, years after the Empire's defeat in the Galactic Civil War. Taun We a female Kaminoan who served as Project Coordinator of the Republic clone army, joined the company as an employee and was stationed at its Vohai headquarters where she continued her research into cloning.
