Finally what can I do to create a helicopter pad on top of the Mk 10 Horizontal GMLS?
Hello - it has been a couple years since I have logged in here, but I saw your question and thought to reply:
Why not consider moving the CWI illuminators for the Terrier system amidships, and create an empty space aft of the stack...then look at a retractable hangar (i.e. FF-1052 or the WHECs), which should probably give you a workable deck for a small helo (Wasp/Alouette/SH-2 type).
