USS Marathon (NCC-3105)

USS Marathon (NCC-3106) was a battlecruiser on active duty in Starfleet during at least the late 23rd century. (Federation Reference Series 3)

Marathon was originally scheduled to be a battlecruiser, but tests of the Menahgas necessitated corrections and improvements to ordnance systems and Bussard collectors, resulting in a subtly improved battlecruiser design.

Marathon was commissioned in the 2280s.
