First captain of the UNSC Infinity
- "You know, I'd think you, of all people, would appreciate living to fight another day."
- — Andrew Del Rio to John-117
- "With more than 30 years of naval experience under his belt and a reputation for bringing his ships home in one piece, Andrew Del Rio was a relatively easy choice for the UNSC’s captain seat on Infinity. Like many of the Navy’s finest, Del Rio’s career grew out of the protracted conflict with the Covenant. Infinity, however, presented a new opportunity for his leadership. Although it was secretly battletested prior to its recommissioning as a peaceful exploration vessel, the ship now finds itself at the doorstep of a mysterious Forerunner world that poses a danger unparalleled in Del Rio’s decades-long career."
- — Halo Waypoint description
Captain Andrew Del Rio was given command of the UNSC Infinity in 2553, on Admiral Margaret Orlenda Parangosky's orders that he should keep the Infinity a secret. It is noted that Del Rio was not Paragonsky's prime choice, as she saw him as more of a manager than a leader. In 2557, the UNSC Infinity was tasked with locating the remaining Halo rings to set up research bases for decommissioning. On Installation 03, the UNSC recovered coordinates leading to a Forerunner Shield World. Infinity set a course for the coordinates, being escorted by several Frigates when the ship was scanned and disabled by the Micro Dyson Sphere on Requiem. Captain Andrew Del Rio requested all UNSC Forces to aid the Infinity once it crash landed on Requiem. The ship soon came under attack, composed of Prometheans and Covenant Remnant, who are repelled by Master Chief John-117. As Infinity experienced a moment of relief, Del Rio focused all resources on freeing Infinity from Requiem's gravity well. John-117 insisted they pursue the Didact but Del Rio dismissed his advice.
Del Rio dispatched the Chief to destroy the gravity well, but when the Spartan returned to inform the captain of his encounter with the Librarian who had revealed that the Didact's objective was to escape Requiem and obtain the Composer to subjugate humanity, Del Rio dismissed his testimony as a hallucination. As Cortana suffered an episode of rampancy, Del Rio ordered her forcible decommissioning only to be challenged by the Chief, who confiscated her AI chip before anyone could. Ordering him to hand it over, the Spartan refused, declaring that if Del Rio won't oppose the Didact, he would. Enraged at this display of insubordination, Del Rio turned to Commander Sarah Palmer of the SPARTAN-IV Corps and ordered her to arrest the Chief, only for her to hesitate as the Chief left the bridge. Sending Lasky to stop the Chief from leaving the ship, Del Rio later brings the Infinity back to Earth only for FLEETCOM to relieve him of command due to refusing to aid the Chief, with Lasky replacing him.
It has also been noted by Frank O'Connor that Commander Thomas Lasky, the main character from the series Forward Unto Dawn, later serves under Captain Andrew Del Rio. According to Lasky, FLEETCOM wasn't pleased when he arrived back at Earth without John-117 so he was forced to step down as Captain and was replaced by Lasky. The attack on New Phoenix could only have served to aggravate the poor standing with FLEETCOM in which Del Rio found himself, since it could have been prevented if he had listened to the Master Chief.
