The Vixinavis-class Provectus was an extremely advanced and experimental vessel. (Adventures of STAG) Many years ago, at a location which has been classified, Federation scientists came across the crashed remains of a vessel unlike any ever encountered before. This vessel originated from another galaxy. The scientists reverse-engineered the ship, gleaning new and unknown technologies. For years, the project remained highly classified, the location of the original crash-site and orbiting research station known only by those entrusted with the secret knowledge. Eventually, they created an experimental hybrid vessel. This ship, classed Vixinavis and given the designation of Provectus (no "USS" prefix), was unique and completely untested.
