Six Corps was built in Lorient on plan by engineer Groignard. After her completion, she was commissioned under capitaine de aisseau de Choras, and departed Lorient on 13 September 1763, bound for Brest, where she arrived on 27 September.
Six Corps was then put in the reserve fleet, and never took part in any military operation. She was almost completely rebuilt in 1775, ordered on 21 June 1779 to be broken up, and broken up in 1780.
