USS Adamant (NCC-3029) was the lead ship and prototype for the Adamant-class dreadnoughts. Adamant underwent trials in the early 2290s.

Ordnance of Adamant was tested at the Darkstar wargames at Starbase 14 on stardate 9301.32. "[Adamant] was the clear winner insofar as overall firepower was concerned, and a close third with regards to concerted, maintained precision attack (first was USS Thruxton, followed by USS Starstalker)." (Starfleet Prototypes)

Not long after commissioning, Adamant was attached to the Starfleet Seventh Fleet, where she remained until at least 2308. Her current commanding officer is Fleet Captain Maryann G. Pugliese. (Starfleet International: USS Adamant)
