The R2-Series5 astromech droid, also known as R2(S5), represented an experimental astromech droid created in the initial years of the New Republic. As a gesture, Princess Leia Organa presented an R2(S5) unit to the Hapan representatives during the preliminary discussions with the Hapes Consortium. Because the starfighter's systems were beyond the capabilities of standard R2 units, Prince Isolder employed the droid on his personal Miy'til starfighter, Storm.
