sounds interesting COL --tell you who the right person to ask about adding new units to the aibase spawn list-- the guy who worked on adding the walrun aircraft can't think of his name of hand--(is it in this thread? ) he said he had problems adding the walrus but he managed it in the end ---
what is wanted i suppose is to add a sub to the airbase spawn list ( i get the feeling it needs to be incoporated into a list some where?) then it's a matter of what happens if it DOES actually spawn!!
