A small-scale fold device capable of displacing a space vehicle such as a fighter through super dimension space, allowing interstellar travel. First utilized in 2040, early fold boosters were not small enough to be internalized within a variable fighter and required mounting upon the exterior of the craft. The fold booster was also designed for short range travel and not certified for performing beyond a one-way 20-light year trip through fold space for reasons of safety (though UN Spacy records do indicate successful folds beyond that limit). Despite these disadvantages, the fold booster enabled deployment of variable fighters across interstellar distances without the need for a carrier vessel. (see also Super Fold Booster).
