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.

//*********************************************************************************************************
Open 'Gui_Global' (C:\Program Files\Activision\Star Trek Armada II Fleet Operations 3.0\Data\Sprites) and look for: 

nbre_yardw5	wireframe04	96	192	96	96		#		

add beneath it:

fed_oberthw5	wireframe10	384	288	96	96		#			

//*********************************************************************************************************
then find:

nbre_yardw5	wireframe04	96	192	96	96		#		

and add beneath it:

b_fed_oberth	federationbuttons04	88	3	80	80		#	2	1
