C.O.V.N.E.T is the top secret national security facility seen in Muppets from Space.
C.O.V.N.E.T's mission is to investigate the threat of extraterrestrial attack. The facility is "cleverly disguised as a cement factory."
It is currently unknown what C.O.V.N.E.T. stands for.
The exterior used for C.O.V.N.E.T. is really the exterior of the Screen Gems Studio in Wilmington, NC, where Muppets from Space and The Adventures of Elmo in Grouchland were filmed. It was previously the Ideal Cement Factory.
