The Foudre-class landing platform dock is a class of landing platform docks designed and constructed for the French Navy. Designated Transport de Chalands de Débarquement, they were intended to replace the ageing Ouragan class and the construction of four vessels was planned. Only two were built and the remaining two were instead reordered as Mistral-class amphibious assault ships. The two ships of the Foudre class, Foudre and Siroco, operated with the French Navy between 1990 and 2014. Replaced by the Mistrals, in 2011 Foudre was sold to the Chilean Navy and Siroco was sold to the Brazilian Navy in 2015.
