Here is a modification of the Knox Class Frigate using the ship Vance built. I removed one of the hanger bays and replaced the “mega phasers” with sensor pods. Personally I never liked “mega phasers”, nor have I ever agreed with the designation of Frigate. So this ship is classified as a Medium Cruiser for research and exploration. The only reason the Reliant had phasers located on the roll-bar was in order to not confuse the audience during Wrath of Khan. Otherwise it would appear as if the Enterprise was firing upon itself.
