They designed a fleet to take on another fleet, but the kid said fuck it, lets take on the planet.
In the book, during that final battle Ender had command of 20 ships with 4 fighters each, for a total of 20 ships and 80 fighters.
On top of that, they were the oldest possible model of ships, because they were launched first due to the homeworld being so far away.
So I'm not so sure they "designed" the fleet to take on another fleet.
