The Catchon-class interceptor was a type of starship on active duty in Starfleet service in the late 23rd and early 24th centuries. Catchons were designed as dedicated warships, similar in mission profile to perimeter action ships. Unlike the perimeter action ships, they were capable of longer missions. (Cf. Dupleix-class perimeter action ships [Starfleet Prototypes], introduced 15 years later in the 2290s, which massed only 123,000 tonnes to the Catchon class's 127,000 tonnes and combined high-warp maneuverability with the longer mission durations of interceptors.)
