The Mark 12 was the latest mod­el in Star­fleet’s line of Class F util­ity shuttles when the Con­sti­tu­tion-class entered ser­vice and like its pre­de­cessors, con­tin­ued to improve on the basic design. Star­fleet’s rap­id expan­sion in the 2240’s and the need for replace­ments for losses incurred dur­ing the Fed­er­a­tion-Klin­gon War ensured that many of these craft were con­struc­ted, becom­ing the “Jeep” of the 23^rd cen­tury. Although get­ting a little long in the tooth, they remained a com­mon sight into the 2280’s.

Game stat­ist­ics for the Class F shuttle­craft can be found in the The Com­mand Divi­sion Sup­ple­ment­al Rule­book for Star Trek Adven­tures, p68.
