Hackett was born in Buenos Aires in 2134. When his mother died in 2146, he was placed in the Advanced Training Academy for Juveniles, where his affinity for science and leadership quickly became evident. Hackett enlisted in 2152, volunteering for high-risk missions to colonize space beyond the Sol Relay. He was commissioned as a second lieutenant in 2156 and participated in the First Contact War the following year. His rare ascent from enlisted man to admiral remains an Alliance legend.
