Project V
From Super-wiki
Project V is the name attributed by the British Men of Letters in regards to their plan to wipe out all vampires in America. Phase one of Project V focused on exterminating all vampire nests in the Midwestern region (MWR). When Project V began, there were a total of 241 vampires spread out across twelve states in the Midwest. By the time Sam Winchester joined with the British Men of Letters, that number had been reduced to a single cell of eleven vampires located in Wichita, Kansas.
