Maybe not show the carriers, but could at least make the base flash. If a flashing base is suppose to represent people around the base seeing enemy airplanes or GVs, I think a fisherman might find the enemy's CV group worthy of telling someone. Not even a fisherman, often it's just someone in the town getting hammered with 8in guns.
**BOOM!**
"Should we call someone about those"
"No, no, no need to call about those"
"Oh look, and airplane"
"THE ENEMY!, SOUND THE ALARM, SCRAMBLE THE PLANES"
