The Bougainville class was a group of colonial avisos, or sloops, built for the French Navy during the 1930s. They were designed to operate in the remote locations of the French Empire.
The Bougainville-class avisos were intended for colonial service abroad in austere conditions. Endurance was one of the primary considerations as were living conditions in tropical climates for the crew. The ships also had to accommodate an admiral and his staff as they could serve as the flagship for the overseas divisions of the French Navy. The designers selected economical diesel engines to power the ships to satisfy the endurance requirements. To help them patrol the large areas that they would be responsible for, the navy elected to equip them with a small, lightweight, reconnaissance aircraft, the Gourdou-Leseurre GL-832 HY floatplane. The ships were equipped with air conditioning throughout and the crew's living spaces were insulated as well. The last two ships, Beautemps-Beaupré and La Pérouse, were to be completed to a modified design with a single funnel as survey ships.
They had an overall length of 103.7 metres (340 ft 3 in), a beam of 12.7 metres (41 ft 8 in), and a draught of 4.15 metres (13 ft 7 in). The ships displaced 1,969 long tons (2,001 t) at standard load and 2,600 tonnes (2,600 long tons) at deep load. The hull was subdivided by 10 transverse bulkheads into 11 watertight compartments. Their crew consisted of 14 officers and 121 ratings in peacetime.
