The first of the Heston-class vessels entered service on reference stardate 1/9105, beginning a series of sixteen vessels that would be in service for decades afterwards in the mid-23rd century. (RPG reference book: The Four Years War)
- Presumably, the first ship of this series would have been called USS Heston, although such a vessel was never specifically named in the sources mentioning this class.
- Fan fiction sources have described the Heston vessels as two-nacelle variants of the Federation-class dreadnought, although currently no licensed or canon sources depict the vessel as such.
