The arsenals of Galor-class warships vary, though typically they are armed with numerous phaser arrays. Although the Galor-class vessels were decidedly inferior to the Federation's Galaxy-class starships, they proved to be very effective against Miranda-class and other older Federation starships. (TNG: "The Wounded"; DS9: "Sacrifice of Angels", "Waltz")
In 2370, Cardassian colonists living in the Demilitarized Zone modified Cardassian shuttles, which they equipped with Galor-class phaser banks to protect their colonial interests. (DS9: "The Maquis, Part I")
The Galor-class was also utilized in the mirror universe by the Klingon-Cardassian Alliance where they were described by Intendant Kira Nerys as being "quick and powerful". These vessels, however, were not without their weaknesses, specifically, their targeting systems could be easily fooled. (DS9: "Shattered Mirror")
In 2367, the Cardassian warships lacked the ability to read Federation starships transponder codes, while the latter had that ability. The Cardassians were granted this ability when Captain Picard gave Gul Macet the Federation's codes to track the USS Phoenix. Federation starships also had superior terminal interface systems. (TNG: "The Wounded")

The Galor first appeared in "The Wounded", and was first identified by name in "Ensign Ro".
It is possible that the generic references made in later seasons to Cardassian warships, Cardassian battle cruisers and Cardassian destroyers were made in reference to the Galor-class starship. It is, however, as equally likely that those references were made with regards to the Keldon or yet unseen class of warship.
While there were never any specific references to the maximum speed of a Galor-class, an observation can be made in DS9: "Defiant", where the warship Kraxon chased the USS Defiant, which was traveling at warp 8 towards the Orias system. The display graphic featuring the pursuit depicted an even match, however, based on the events in the episode, the Kraxon was not moving fast enough to catch the Defiant before it reached its destination.
Brandon MacDougall posted the real-world length of the LightWave model he built for the sixth and seventh seasons of DS9: "I loaded the 3D model up and she's around 368m [1207 feet]. I would've checked with Rick [Sternbach] at one time regarding the size when laying it out." wbm A camera test model from an auction contains a handwritten note: "Cardassian 1200 ft [366 meters]".  Visual Effects Supervisor David Stipes noted that the "Galor is about 1200 ft."  When asked whether he had a definitive size, Rick Sternbach replied:
Definitive? Not really, but I can try to make a guess. I pegged it at ~371m in the DS9TM, and just now measuring a reduced xerox of my starboard elevation ortho (and assuming a humanoid-comfortable deck height of ~3.8m), I get 379.6m, not far off from what I thought for the book. Will there ever be an authoritative figure? Probably not, but the number I get could be considered "original intent," ... wbm
A couple of sources imply that the Galor was intended to be approximately 3/4 as long as the Enterprise-D. An article in the magazine Sci-Fi & Fantasy Models #16 states that the Galor miniature was in scale with the four-foot miniature of the Enterprise-D.  Ed Miarecki also recalled such a consensus between him and Rick Sternbach. wbm If so, the overall length can be estimated at (~37 inches / ~49.25 inches) * 2108 feet = ~1580 feet (~480 meters). Larry Nemecek likewise wrote that "Rick S[ternbach]'s original length was 1,587 ft, or @ 3/4 the length of the Galaxy-class."
