Just started with DH and I notice in my (German) ship construction screen there is a ship called 'Experimental light carrier (CVE-3)'. It looks like an old model and has no CAG (?) but it has an astonishing sea detection (SD) ability. I looked for more details in the manual and online but as usual (I've been playing hoi2 for years) the documentation is non-existent, so like most of the hoi2 stable the unit and its abilities is a complete mystery. Still wondering why nobody is talking about this since the SD is 10 and the next best, the DD, is a mere 3. Anybody out there with a hint?
