A system for launching and recovering an autonomous underwater vehicle using a surface carrier ship, the carrier ship including a hull with a bottom, the autonomous underwater vehicle including and propelling, guiding and stabilizing means, the system including, in addition to the carrier ship, a subaquatic vehicle wire-guided by a connection wire connected to the carrier ship, wherein the subaquatic vehicle can be positioned in two main configurations, a storage configuration in which the subaquatic vehicle is removably attached to the carrier ship in a storage area of the carrier ship and a use configuration in which the subaquatic vehicle, separated from the carrier ship (2, 6, 7), is in water and remote from the storage area of the carrier ship while remaining connected to the carrier ship by the connection wire, said subaquatic vehicle including propelling, guiding and stabilizing means, and a docking station for the autonomous underwater vehicle, allowing a removable attachment of the autonomous underwater vehicle to the subaquatic vehicle for transporting the autonomous underwater vehicle to its launching location, where it will be released from the subaquatic vehicle, the subaquatic vehicle and the autonomous underwater vehicle including complementary automated docking means allowing the launched autonomous underwater vehicle to automatically dock with the docking station of the subaquatic vehicle during the recovery and to attach thereto, characterized in that the storage area of the carrier ship is a submerged end of an appendix of the carrier ship hull, the appendix being a keel and in that the subaquatic vehicle is stored at the lower end of the keel, the carrier ship being a carrier ship with a keel, and in that in the carrier ship with a keel, the keel includes at its lower end a bulb or a gondola, the bulb or the gondola including a recess intended for the storage of the subaquatic vehicle. the system including, in addition to the carrier ship, a subaquatic vehicle wire-guided by a connection wire connected to the carrier ship, wherein the subaquatic vehicle can be positioned in two main configurations, a storage configuration in which the subaquatic vehicle is removably attached to the carrier ship in a storage area of the carrier ship and a use configuration in which the subaquatic vehicle, separated from the carrier ship (2, 6, 7), is in water and remote from the storage area of the carrier ship while remaining connected to the carrier ship by the connection wire, said subaquatic vehicle including propelling, guiding and stabilizing means, and a docking station for the autonomous underwater vehicle, allowing a removable attachment of the autonomous underwater vehicle to the subaquatic vehicle for transporting the autonomous underwater vehicle to its launching location, where it will be released from the subaquatic vehicle, the subaquatic vehicle and the autonomous underwater vehicle including complementary automated docking means allowing the launched autonomous underwater vehicle to automatically dock with the docking station of the subaquatic vehicle during the recovery and to attach thereto, characterized in that the storage area of the carrier ship is a submerged end of an appendix of the carrier ship hull, the appendix being a keel and in that the subaquatic vehicle is stored at the lower end of the keel, the carrier ship being a carrier ship with a keel, and in that in the carrier ship with a keel, the keel includes at its lower end a bulb or a gondola, the bulb or the gondola including a recess intended for the storage of the subaquatic vehicle.
