The Quadjet is a technologically advanced predecessor to the Quinjet, built by Project P.E.G.A.S.U.S. for transportation of cargo. A Quadjet was commandeered by Vers and Nick Fury during the Ambush at Joint USAFA Facility, later being used to ascend to Mar-Vell's Laboratory.
While being pursued by S.H.I.E.L.D. through Project P.E.G.A.S.U.S., the Starforce member Vers and Nick Fury were cornered in the facility's hangar bay, where they spotted the Quadjet. Sneaking inside, Vers was able to pilot the ship to Fury's surprise, where they then managed to escape the facility. Much to their surprise, they discovered the Flerken Goose had stowed away on the ship, and was experiencing discomfort due to the G-Force.
In order to investigate more of her past, Vers piloted the Quadjet to the Rambeau Residence in New Orleans, Louisiana. Parking the jet in a field nearby the house, Vers and Fury entered the garage, where Maria Rambeau and Monica Rambeau were shocked to see Vers still alive. The Skrulls Talos and Norex soon followed the Quadjet to the Rambeau Residence, where they explained their plight and Vers' origin. Coming to an alliance, Norex offered to upgrade the Quadship to survive in space, allowing them to travel to Mar-Vell's Laboratory.
While the Quadjet was being upgraded, Carol Danvers approached Maria Rambeau, asking her to help her fly the jet. Maria was unwilling, attempting to use Monica as an excuse. Monica helped convince Maria, who decided to call her parents to babysit Monica, agreeing to help fly the ship.
Blasting off, the Quadjet quickly gained altitude, where Danvers then activated the upgraded thrusters, pushing the jet through the atmosphere and into orbit. Goose, being untethered to anything, floated around the cockpit until Nick Fury gently grabbed her, until artificial gravity was activated. Locating the Mar-Vell's Laboratory, Danvers disengaged the lab's cloaking field, allowing the team to dock with the lab, entering the facility.
- "Get on the ship. Let's go, let's go."
Locating Mar-Vell's Laboratory, the Starforce docked with the laboratory themselves. Seeing the Quadjet, Yon-Rogg stationed several Kree soldiers to guard it, ensuring that the Skrulls could not escape the lab. When the Skrull population of the lab was escorted to the hangar bay for execution, Talos revealed his deception and killed the Kree guards, allowing the Skrulls to board the Quadjet. Monica Rambeau quickly launched the Quadjet, intending to escape the lab. However, Yon-Rogg saw the ship taking off, and managed to wound Talos with his pistol through the closing cargo doors. With his targets escaping, Yon-Rogg dispatched Minn-Erva in a scout ship to destroy the Quadjet. Engaging in a dogfight in the Mojave Desert, Rambeau utilized the Quadjet's superior maneuverability to flank Minn-Erva, allowing her to use the Quadjet's turrets to destroy the scout ship, killing Minn-Erva. In celebration, Fury played with Goose, who scratched Fury's face, blinding him in his left eye. Safely out of the combat, Rambeau piloted the ship back to her home, where the Skrulls temporarily stayed until they decided to use the Laboratory to explore for a new world.
The Quadjet was an aircraft with vertical take-off and landing capabilities, achieved through two large, angle-adjustable rotors, one housed in each wing, which was also used to allow the ship enhanced maneuverability. The Quadjet also possessed a variety of weapons, including a GAU-17/A Gatling Gun, mounted on the underside at the front of the jet. After being upgraded with Skrull technology, the Quadjet was capable of achieving space travel, with artificial gravity being installed to prevent discomfort.
