The 98+/99+ registered airframes are not line Eurofighter (those are 30+ and 31+ registered aircraft), but are assigned to Wehrtechnische Dienststelle für Luftfahrzeuge und Luftfahrtgerät der Bundeswehr (WTD 61) as prototype/test aircraft. As such they also come with equipment Luftwaffe opted not to have installed into its line fighters, like PIRATE. I cannot recall if TrueGrit already indicated if the inital release will or will not include PIRATE.
