[2021] Why there is no mentioning of the minimal striking distance of the ASW airstrike?

I don't know why anyone would expect ASW planes to damage land installations. Gameplay-wise or Realism-wise.
The airstrikes are the longest-distance tool available for combatting Subs outside of direct gunfire. This is the tool Cruisers and BB's were given to insure that they have some proper methods of doing damage back to submarines considering their generally slower speeds than DD's. DD's, on the other hand, have the close-range capabilities that allow them to make a sub kill nearly certain when they come upon one.
Keep in mind: a submarine inside the minimum distance for airstrikes will not be able to land torpedoes without being near the surface, where secondaries and main battery gunfire will be lethal to them.
Why is this not mentioned in the tooltip? I'm not sure. Many things are not mentioned in the tooltips if you dig hard enough. A push of the "4" key will show you immediately that there is a minimum distance, so to me it's not a crucial piece of info worthy of screen real-estate.
