The Scipion class was a class of three 74-gun ships built to a design by François-Guillaume Clairin-Deslauriers, the ingénieur-constructeur en chef at Rochefort Dockyard. These were the shortest 74-gun ships built by France since the 1750s, and they were found to lack stability as a consequence. The third ship - originally the Pluton - was 'girdled' (sheathed) with 32 cm of pine at Rochefort in 1799 to overcome her instability, and the design of two further ships ordered at the same dockyard in 1779 were lengthened.
