The Keldon class is the most powerful vessel in the Cardassian fleet. Essentially an uprated Galor class vessel with an additional hull section added to the dorsal surface,5 the Keldon class is an improvement on its predecessor in almost every respect. The secondary armament has been boosted from twelve to fourteen disruptor banks, while the primary phaser has been upgraded to put it on a par with a Type X phaser array. The photon tubes are capable of firing at more than twice the rate of the Galor class tubes, and the Keldon includes a great deal of new sensor and computer equipment designed to increase its ability to target vessels under cloak or capable of a high level of manoeuvrability. The shield system has been heavily upgraded, while the hull beneath has received a layer of high density armour plate.

While these measures put the Keldon class significantly above the Galor, they still do not rank with the larger, more sophisticated ships that the larger alpha quadrant forces can field. The Cardassians planned to produce the Keldon in huge numbers to compensate for this - over three hundred were planned, but the difficulties suffered by Cardassia in the last few years have made this more a fond hope than a realistic plan.

The Keldon is known to be the most powerful ship class in the Cardassian fleet, and appears to be a Galor with an extra hull section added to it. Like most Cardassian designs I've made it a sort of solid, reliable and not very sophisticated ship that isn't really up to the likes of the Nebula, Vor'Cha and Galaxy but is probably still better than the average alpha quadrant warship.

The Heavy Cruiser designation, mass, dimensions and speed are from the DS9 TM.
