NASA completed the first flight of a new laminar-flow scale-model wing on an F-15B testbed that aims to cut drag and reduce fuel burn on future aircraft.

The CATNLF article is not a full wing. It is a 40-inch-scale model that NASA mounted under the F-15’s belly, standing upright like a fin. NASA picked that configuration to enable the testing of the design in real flight conditions without building a new aircraft.
