Some country change datum (US use NAD-27, then NAD-83, then WGS84; Russian use s-42 now PZ-90 (same WGS84)). For accurate calculation in need understand type of datum in Romania in WWII. Without this information mistake in calculation can be 150-1000 meters.

Yep, this is soviet standard. And now i'm sure - Romania in WWII use other datum.

I am sure those charts were at least European compatible. Are you looking for shipwrecks ? There are some websites with The Black Sea wrecks...
