  It's a launch platform without clear future missions or funding. After the surplus RS-25 engines from the shuttle program are used (designed to be re-usable, they are heavy and expensive and will be destroyed by the launches) it's not clear what will power the launch vehicle. It's a very expensive big rocket with an unclear future in both engineering and political terms.
