Probably is America and not Enterprise, look at the location and you'll se it is in Philly where America sat after it's last cruise in '96 until it was recently sunk as part of a test to see how battle damage would affect a modern carrier.
It's the America. The Enterprise has a cubic shaped island, sort of like a square mushroom made out of Legos. The Enterprise is still in commission at Norfolk.

Its the America at the former Philly Naval Shipyard. She was towed out to sea and sunk by the Navy last spring. More info can be found here. I was on her shortly before they towed her out as part of her veterans last look-sie.
