As presented at Warship 2009: Air Power at Sea.
Immediately forward of the EH-101 is a lift which, when down forms the lower deck of a hangar for the two aircraft shown. A mission bay is included on the centreline, essentially an extension of the hangar to the stern. There may be a stern door, but it is not clear.
The hangar is closed by a door, which rotates out of the way to allow the lift to be raised. The flight deck is surrounded by a catwalk to allow the deletion of flight deck nets, and the lower superstructure reduces flight deck turbulence. The mast has an ARTISAN-class MRR inside an enclosure.
