Good question! The researcher often overlooks the obvious questions as he delves into other aspects. It is the obvious question that needs responce, too! Thank you!
Along Battleship Row and Carrier Row are the huge concrete mooring quays on to which the ships tied. They became known as "Fox" quays as they had been painted with the large letter "F" followed by the number of the mooring position. Other mooring points had their own numbers assigned, but no all were painted with the position.
When the USS Tennessee and USS Maryland were stuck by the outboard sunken ships, one of the quays was blown up to unstick a ship. [I'll hafta look up which ship]
These "Fox" quays had been painted white and marked with the location of the ships on 7 Dec for better understanding by those visitors to the USS ARizona Memorial. The USS Missouri now blocks view of the quays on to which the USS Maryland tied.
