Pallas-class frigate (1808)
The Pallas class constituted the standard design of 40-gun frigates of the French Navy during the Napoleonic Empire period. Jacques-Noël Sané designed them in 1805, as a development of his seven-ship  of 1802, and over the next eight years the Napoléonic government ordered in total 62 frigates to be built to this new design. Of these some 54 were completed, although ten of them were begun for the French Navy in shipyards within the French-occupied Netherlands or Italy, which were then under French occupation; these latter ships were completed for the Netherlands or Austrian navies after 1813. Ships launched in 1807 (1)
