This isn’t a request just a suggestion. It would be nice for the use of cruise missile type units early on in the game. I use a powder keg cruise missile for use on land (often referred to as a petard). The powder keg and the units I’m suggesting have only 1 bombard range.

These units can help turn the tide on much more powerful and better funded fleets.
One Special attack unit made by Wyrmshadow was the Okha http://forums.civfanatics.com/resources/okha.10198/
