List of French Sail Frigates - Classification of Frigates

Classification of Frigates

Early French naval frigates, until the 1740s, comprises two distinct groups. The larger types were the frégates-vaisseau, with batteries of guns spread over two decks; these were subdivided into frégates du premier ordre or vaisseau du quatrième rang (French Fourth Rates) usually with a lower deck battery of 12-pounder guns, and an upper deck battery of either 8-pounder or 6-pounder guns; and frégates du deuxième ordre or vaisseau du cinquième rang (French Fifth Rates) with a lower deck batter of 8-pounder guns, and an upper deck battery of either 6-pounder or 4-pounder guns. The smaller types were the frégates légères, with a single battery of (usually) 6-pounder or 4-pounder guns, plus a few small guns on its superstructure or gaillards. The 'modern' sail frigate, with its main battery on the upper deck, and no ports along the lower deck, emerged at the start of the 1740s.

The article categorises frigates according to the weight of the projectile fired by the main battery; the first 'true' frigates in the 1740s carried either 6-pounder or 8-pounder guns, but development soon standardised around the 12-pounder frigate, carrying thirteen pairs (occasionally fourteen pairs) of 12-pounder guns on the upper deck, and usually three pairs of 6-pounder guns on the quarterdeck and forecastle (collectively referred to as the "gaillards" in French). During the American Revolutionary War, larger types carrying an 18-pounder or even 24-pounder main battery (and more secondary guns on the gaillards) were introduced, and following the French Revolution these became predominant. Finally in the 1820s, a new type of 30-pounder armed frigate was brought into service.
