Naval scouting in SP?

[B1GB0M]

How do you go about scouting naval targets, particularly as an Axis that has invested heavily into Navy for a Sea Lion? Is this a good use case for maritime bombers or is this something DDs should be tasked with?

This would be for SP, so please don't tell me if the AI just keeps its ships in certain tiles. I'd rather not know if that's the case [;)]
