The original Jetfire was a toy released in 1985, in the second wave of Transformers. Hasbro decided that the Autobots needed some kind of air support, and went looking for a toy to fill the role. They found what they were looking for in the Super Dimension Fortress Macross toy, the VF-1S Super Valkyrie.
天火最初作为第二波变形金刚玩具于1985年推出。HASBRO觉得汽车人部队需要空中支援,便着手开发玩具以填补这一空缺。他们在SUPER DIMENSION FORTESS MACROSS(太空堡垒?)中发现了目标:VF-1S SUPER VALKYRIE。
Takatoku, the toy's original creators had gone bankrupt, and Matsushiro, apparently the company that did the actual molding and manufacture, bought the rights (or perhaps used them without rights) and stepped up to the plate of producing the toys.
To prepare the toy for the American market they removed the missiles and yanked the springs from the (GU-11) gunpod so it couldn't fire them even if they had the missiles, and filed off the nose of the plane so it wasn't quite so pointy. (It's also visibly shorter...) They also modified the colors, adding more red on the body (and nose), coloring the armor red, changing the emblems (stickers and whatnot) and adding to them. The Jetfires by Matsushiro are the "rare" Macross symbol Jetfires...
