In 2030, Shinsei Industry and General Galaxy competed in Project Nova to determine the next main variable fighter for U.N. Spacy. Shinsei’s YF-11 Thunderbolt won that competition, and a decade later the two companies competed again in Project Super Nova to select the fourth generation successor to the VF-11B Thunderbolt. Designed by Shinsei engineer Yang Neumann, the YF-19 prototype incorporated small canard wings like the VF-11B before it, as well as forward-swept wings. The YF-19 also incorporated advanced control avionics, an active stealth system and significantly faster transformation time than the VF-11B. It was also capable of unassisted escape from a planetary atmosphere. With its larger airframe, the YF-19 was able to incorporate missiles, which the VF-11B lacked without Super parts. The YF-19’s armaments included a Gatling gun pod, an anti-aircraft laser gun, two converging energy cannons, various missile options, a pinpoint barrier system and a bulletproof anti-projectile shield. The YF-19 could also mount optional FAST Packs.

Project Super Nova was carried out in early 2040 on planet Eden’s New Edwards Test Flight Center, where Shinsei’s YF-19 competed against General Galaxy’s YF-21. The YF-19 earned a reputation for being difficult to control and went through several test pilots until the assignment of Isamu Alva Dyson, a U.N. Spacy pilot with a long record of recklessness and insubordination. Testing was complicated by the hostility between Isamu and YF-21 pilot Guld Goa Bowman, who had a falling out seven years earlier. The YF-19 exceled in many tests compared to the YF-21, but in March U.N. Spacy decided to cancel Project Super Nova in favor of replacing all manned variable fighters with the new unmanned AIF-X-9 Ghost. Displaying his characteristic recklessness, Isamu was joined by Yang in stealing the YF-19 and a fold booster to travel to Earth and crash the unveiling of the AIF-X-9 at the ceremony marking the 30th anniversary of the end of Space War I at Macross City. 

Guld gave chase in the YF-21, resulting in a duel where the two men finally put their differences aside and rekindled their friendship. However, they were then attacked by the AIF-X-9, which was commandeered by the virturoid idol Sharon Apple. Equipped with a dangerous bio-neural chip, Sharon became emotionally unstable and decided to attack Isamu to give him the ultimate thrill as a show of love. Guld defeated the AIF-X-9 at the cost of his life, and Isamu was then attacked by the Macross itself, which had also been seized by Sharon. Isamu ultimately defeated Sharon by destroying the Macross’ computer core. Following the Sharon Apple Incident, U.N. Spacy selected the YF-19 as its next variable fighter in 2041, and it went into production as the VF-19A Excalibur. However, after several years of phased rollouts, U.N. Spacy cancelled the wide-scale adoption of the VF-19 for several reasons, including the lack of skilled pilots, production costs, and new arms export controls on emigrant fleets and colony worlds. As a result, it instead adopted in 2050 General Galaxy’s VF-171 Nightmare Plus, a redesigned version of its VF-17D Nightmare. Nearly two decades after his involvement with Project Super Nova, Isamu worked for the private military company SMS and piloted a VF-19EF/A that used the YF-19’s color scheme.
