The Ouragan class (French: Hurricane) was a series of French landing platform docks operated by the Marine Nationale. They were called Transport de chalands de débarquement (TCD) (in English: landing craft transport). They were replaced by the Mistral-class amphibious assault ships.

The Ouragan class displaced 5,965 tons empty and 8,500 tons loaded. They were 149 m (489 ft) long with a beam of 21.5 m (71 ft) and a draught of 5.4 m (18 ft). They had a complement of 205 personnel with the ability to carry up to 470 troops.

The class was designed for multi-mission capability. They had the ability to complete a fast loading and unloading of landing craft, and other equipment, carrying troops and vehicles for a land mission. The vessels could carry, supply and operate helicopters transporting commandos or providing close support. They could transport the mission crew and command a landing operation of limited scale.

The landing was accomplished by means of an unloading barge transported in an interior raft called a radier. The TCD could simultaneously transport, refuel and put into operation four heavy helicopters, while ensuring the control of a limited landing operation, hospitalization and care of the wounded.

The essential characteristic distinguishing the TCD was the interior raft or radier, which was submersible in 3 m (9.8 ft) of water and with a rear door that put it in contact with the water. The ship had a 120 m (390 ft) long well deck that could be submerged 3 m (9.8 ft) under water. The movement of water within the ship was control by sluices, valves and automatic pumps. The ships were supplied with two EDICs (Landing Craft Tanks) which carried 11 light tanks or could accommodate 18 LCMs within the well deck. They could carry a variety of other loads. They were also designed as repair ships, able to dock ships up to 450 t (440 long tons; 500 short tons) within their well.
