Bahia and her sisters in the Foudre class was designed to load a mechanized regiment aboard and act as its logistical support vessel once in theatre.
Brazil’s naval power is ranked among the top in the South American region. It owned several amphibious ships, the largest of which was the Bahia, hull number G40. Bahia is classified as a landing platform dock, formerly owned by France as Siroco L9012 of the Foudre class, then acquired by Brazil in August 2015, and transferred to the Brazilian Navy as the multipurpose amphibious ship Bahia (G40).
Bahia and her sisters in the Foudre class was designed to load a mechanized regiment aboard and act as its logistical support vessel once in theatre. Each ship of the class displaces 11,300 tonnes at standard load and 12,000 tonnes at full load. The vessels are 168 m long with a beam of 23.5 m, and a draught of 5.2 m.
Bahia carry large stowage areas which can be used to ferry main battle tanks and vehicles, a 52-ton elevating platform, a lateral ramp and a flight deck able to simultaneously operate several helicopters. Three rotations of such ships can ferry a whole armoured regiment with its 22 main battle tanks, 44 heavy armoured vehicles, 41 all-terrain light vehicles, and up to 50 other vehicles.
In terms of personnel, the Bahia can accommodate 467 troops or as many as 1,600 troops for an emergency situation. With 700 personnel embarked, the vessel has an endurance of 30 days. The aeronautical installations allow all-weather operations of transport helicopters, intended to carry commandos. There are two landing spots on the flight deck plus one on the removable rolling cover above the well deck. 4 helicopters such as EC-725 or SH-60 Seahawk can be accommodated in the hangar.
