A test article is a version of space craft or related vehicle or equipment, built as a platform to perform testing. Test articles are built to the same specifications to replicate conditions and behaviors of flight ready versions. Test article version are also built without the certification and quality control steps taken with the versions intended for flight. Test articles are more complete than a boilerplate. Test articles can sometimes be upgraded to flight ready status. Of the 136 Space Shuttle external fuel tanks produced, one was retained as a test article. The contractor producing the tanks commented that that tank could be refurbished for flight use if necessary. The static test article for the Dream Chaser lifting-body spaceplane "will become the atmospheric flight test vehicle in 2012 for drop tests." Test articles are often displayed in museums because of their accuracy. Museums may refurbish test articles to match more modern configurations.
