Has Vehicle Class

Connects a launch vehicle to the concept naming the class of launch vehicle it belongs to, such as an expendable launch system, a reusable launch vehicle, a sounding rocket, a human-rated launch vehicle or a small-lift launch vehicle. The inverse reading, Vehicle Class Of, names the same link from the class toward each launch vehicle grouped under it. This relation gives the vehicle class already recorded as an enum fact on each launch vehicle a durable entity identity; it does not replace that enum fact, which keeps classifying every launch vehicle exactly as before.
