The YF-4 Lightning, also known as the VF-X-4, was the prototype of the VF-4 Lightning Advanced Veritech Fighter. It had been a concept since at least 2014, but did not actually see creation until 2015. Some source suggest that the vehicle was abandoned due to cost, while others suggest that different models of the vehicle could still be in use through the Second Robotech War and up to the start of the Third Robotech War in 2031, although in limited numbers.


YF-4 Rick Plays 23

Rick Hunter owned a model of the YF-4 in January 2014, long before the first was known to be built. He played with it while considering if he should quit the military, as Lynn Minmei wanted. (Macross Saga: To the Stars)

The YF-4 was in service at least by 2015. In that year Captain Rick Hunter took the YF-4 into battle after Wolf Squadron was ambushed by rebel Zentraedi. Despite a transformation malfunction that prevented the YF-4 from changing into Guardian mode, Hunter was easily able to destroy two Destroid Monsters.

Behind the scenes


The newly-designed three modes

The YF-4 appeared only in fighter form as a display model. Although a three-mode transformation exists for Super Dimension Fortress Macross, it is not valid.

New transformations were made for the fighter for its appearance in Robotech RPG Tactics, but it was never released as part of the canceled Wave Two line.
