In Delta Quadrant: Horizons, there are several classes of ship that can be researched and built. Each class has advantages and disadvantages that you must learn to exploit if you wish to build a successful fleet.

While small ships are cheap, and available near the start. These ships have little space, and can carry less weaponry and equipment than a larger ship. Large ships however are slow, and require more advanced engines to keep up with the smaller ships, and this can hold your entire fleet back. They are also less evasive, and this makes them easier for enemy attacks to hit.
