The image below is the first screenshot of Wing Commander III's gameplay ever released to the public. An Arrow flies past... a triangular Kilrathi transport. It's a design you know... but it's NOT a ship that appears in the game! (Triangle transports do appear in 'Kilrathi fleet' cutscenes, but they are generally rendered too small to identify at 640x480.)
What happened? For reasons unknown, the Wing Commander III team opted to cut the triangle transport from gameplay and instead use the 'tanker' model that had been created for a specific Behemoth-refueling mission as the generic Kilrathi transport. These 'skeleton' transports became familiar targets...
The triangle transport then immediately started appearing elsewhere. The 3DO port of Wing Commander III restores these noble wedges to their proper place as the game's main Kilrathi transport and the Wing Commander CCG even includes a card of them!
One of the first screenshots released for Wing Commander IV again showed the triangle transport, prompting much discussion as to the role of the Kilrathi in the game. We now know the footage is Melek's 'evidence,' proof that Admiral Tolwyn has been attacking innocent shipping lanes. (Interestingly, transport again does not appear in the game itself... only in the cutscene!)
The triangle transport is still hidden in Wing Commander III PC's files. Here he is in all his glory:
There's even a 'destroyed' version included in the game; unlike other 'lost' ships, the triangle transport must have been fairly close to finished. (Though there's no apparent location for turrets.)
Finally, Star*Soldier managed to name the triangle transport "Dukara," following the 'D' style name for transports introduced with the Dorkir and Dorkathi in Wing Commander I and II (respectively.) Note that the VDU image used in the magazine is NOT the image included in Wing Commander III 3DO.
