Hmm, the fleet vs. ship minefield argument (that many single ships will die to a minefield, but a fleet will survive) only seems true to me if all of the ships have orders to move specifically into the minefield sector and/or they arrive at the same time. Otherwise, a single ship destroyed by a minefield will create a known minefield marker, which will cause all the other ships to automatically avoid the minefield, unless the race is set to deliberately fly into minefields.

So it is also possible that a fleet will get wiped out by a minefield, when a bunch of smaller ships would only lose one ship. It depends on the situation.

In fact, if you don't have minesweepers, sending a single scout slightly ahead of a fleet can save your fleet from destruction.
