There is no set number; like all fleet commands around the world, the number of naval assets assigned to 2nd Fleet changes constantly. This is because ships form different Task Forces, Battle Groups, etc., and may leave the 2nd Fleet's operational command area and enter another, or they're formed/assigned as tactical considerations warrant. Ships and other assets that might be assigned to 2nd Fleet's command may be from another Fleet; it depends on the situation and needs of the Navy.
