In the past I always thought that the Constitution class was the pinnacle of human technology at the time of Kirk and slightly before (Pike's time). It represented the best both in terms of technology and in terms of combat capabilities that the federation had to offer.
The first season of Discovery presented the Discovery as quite technologically advanced and also having great offensive and defensive combat capabilities. In season 2 we saw a direct size comparison between the Discovery and the Enterprise (seeing them side by side), which looked to me like the Discovery had a slight size advantage compared to the Constitution class.
That made me wonder if there is any info on the combat capabilities (armament, shields) of the Discovery itself and how strong this is compared to a Constitution class vessel?
