A two-seat, twin-engine aircraft, the F-4 Phantom Fighter was built as a long range supersonic jet interceptor back in the 1958. Originally constructed by McDonnell Aircraft for the United States Navy, the jet first entered service for America in 1960. Many different variants of the aircraft were constructed overtime, including a model called the F-4B that saw service in the Vietnam War against MiG fighters.
By 1988, a new type of foe had surfaced, though. The Messiah 13 aliens, hailing from the Third Planet of Yomi, had set their sights on Earth as a new conquest. Using a combination of their Hell Fighters ships, elctro-wave disturbance and espionage, the extraterrestrials overpowered Earth's defenses. During their siege, the aliens learned of the Goten, a mammoth warship being constructed on Earth by professor Masato Takigawa. Seeing the warship as a potential turning point in the battle, the alien forces focused their efforts on destroying the Goten's base and halting its completion.
Part of this alien strike included hunting down any potential individuals who might aid in its construction and launch. One such member was NASA's Jimmy, who was frantically traveling from the United States to join his comrades at the Goten base. To make the journey, Jimmy piloted a F-4 Phantom Fighter. Despite the speed of the aircraft, though, a Hell Fighter spotted and caught up with the American ship. Realizing the hopelessness of staying onboard, Jimmy parachuted out of the craft. The escape came just in time, as the Hell Fighter used its Cosmo Laser Cannons to destroy the F-4 Phantom. Luckily for Jimmy, he was nearly on top of the base when he parachuted. Dodging Pulse Laser Cannon fire, the NASA worker leapt into the water below so he could swim to the base and join in the efforts to launch the Goten.
