NOTE: I made this on a game that includes the altered sprites from the Miranda Class (In the thread called 'Help with Importing ships'), I am not sure if it works without those altered sprite files.

In addition to these, you should also add it to the list of vessels in the Warbird Yard. Preferably before the D'deridex/Warbird Class.
