The Nymphe class was a class of four 34/44-gun frigates of the French Navy, designed in 1781 by Pierre-Augustin Lamothe. The prototype was one of the earliest of the frigates to be armed with 18-pounder long guns. The first two - and - carried 34 guns comprising twenty-six 18-pounders on the upper deck and eight 8-pounders on the quarterdeck and forecastle. The latter two - and - carried an increased armament of 44 guns comprising twenty-eight 18-pounders on the upper deck and twelve 8-pounders plus four 36-pounder obuses on the quarterdeck and forecastle. Thétis was retro-fitted by 1794 to carry the same increased armament as the last two; she was rebuilt at Rochefort from October 1802 to September 1803.
The design followed on at Brest from an earlier class of three smaller frigates (armed with 12-pounder long guns) - named (1777), (1778) and (1780) - built at Brest to a different design by Lamothe's father.
These three ships were named on 11 April 1777, 29 September 1777 and 4 December 1778 respectively.
