[5] The Foudre class carry large stowage areas which can be used to ferry battle tanks and vehicles.

[1] They can also store two landing craft vehicle personnel suspended from davits abeam the aft part of the docking well.

[2] The landing craft can be put to sea by filling ballast tanks lowering the ship, and opening the rear door, flooding the well deck with 3 m (9.8 ft) of water.

[4] They also sport a 600 m2 (6,500 sq ft) hospital area located beneath flight deck in order to ease transfer of casualties.

They each have a flight deck amidships capable of operating two Super Puma helicopters simultaneously.

Foudre's flight deck, measuring 1,450 m2 (15,600 sq ft) has two landing spots but only one fitted with SAMAHE haul-down systems.

Both ships can add an additional 30 by 15 m (98 by 49 ft) landing spot on portable helicopter and vehicle stowage platform aft.

[2] The Mistral missile has an infrared homing to 2.2 nmi (4.1 km; 2.5 mi) with a 3-kilogram (6.6 lb) warhead.

[3] The 30 mm guns can fire a 0.36 kg (0.79 lb) shell 1.6 nmi (3.0 km; 1.8 mi) and up to 800 rounds/minute.

For electronic warfare, the vessels mount Thales ARBB-36 jammer and SLQ-25 Nixie towed torpedo decoy systems.

[1] In June 2010, French defence minister Hervé Morin offered Foudre to the Argentine Navy during his visit to Buenos Aires.

[6] Argentina had already declined the transfer of the Ouragan-class vessels in the past and was more interested in seeking French support for a locally built amphibious ship instead.

The 2013 French White Paper on Defence and National Security said that Siroco would be decommissioned, a decision confirmed in October 2014.

[10] After negotiations with Portugal failed, Siroco was sold to Brazil in July 2015 and entered service with the Brazilian Navy as Bahia.
