A notable and popular mecha from the MACROSS series.
The VF-1 Valkyrie is Earth's three-form transformable aerospace multi-role combat mecha developed from alien overtechnology obtained from the SDF-1 "Macross" space craft. Its armaments include a modular gunpod, laser cannons and several missiles. It can be equipped with modular attachments such as reactive armor and external fuel/thruster packs.
It first appeared in Choujikuu Yousai Macross (1982) where it was created by the U.N. Spacy to fight a race of humanoid alien giants called Zentradi. It was eventually succeeded by the far more advanced VF-4 Lighting III.
In real life the VF-1 was designed by Kawamori Shouji in the early 80s. The design of the mecha's fighter mode is loosely based on the F-14 combat jet and its name is a tribute to the XB-70, Kawamori's favorite aircraft.
