Ship comprising a system for adapting a removable module and adapted removable module

A functionalized ship extending longitudinally between a bow on the front and a stern on the rear, the functionalized ship comprising:

• a removable module;
• a base ship comprising an adaption system configured to adapt the removable module, the removable module installed into said adaption system to adapt the base ship to form the functionalized ship;
• at least one deck;
• one shell being symmetrical with respect to a longitudinal vertical sagittal plane, a lower face of the shell configured to be submerged, the lower face defining a front hull portion towards the front of the functionalized ship and defining a rear hull portion toward the rear of the functionalized ship, the rear hull portion comprising two parts assembled together in the base ship, the rear hull portion including
• a sagittal hull part of the base ship, and
• a U-shaped hull part, having a U-shape in vertical view, the U-shaped hull part being in continuity with the front hull portion, the two legs of the U defining two rear lateral shell parts, the two rear lateral shell parts being closed on the rear by two lateral tables, the sagittal hull part of the base ship being disposed between the two legs of the U of the U-shaped hull part;
• a propeller;
• and
• two rear lateral deck parts in the rear part of the base ship towards a top of the base ship, the two rear lateral deck parts topping the two rear lateral shell parts, the two rear lateral deck parts, the two rear lateral shell parts, and the two lateral tables delimiting two rear lateral volumes of the base ship,
• wherein the removable module is configured to be inserted and secured between the two rear lateral volumes of the base ship to form the functionalized ship, the removable module having a lower face forming a sagittal hull part of the functionalized ship,
• the removable module is removable and configured to be replaced by another module, at least one of the modules allowing launching to water and recovery on the functionalized ship, for storage thereof out of water, of a marine or underwater drone configured to dock in said removable module, and
• wherein the removable module is U-shaped in vertical view, said removable module being open towards the rear, the top and at least in part towards the bottom to delimit, when said removable module is inserted the base ship, a longitudinal sagittal maneuvering area towards the rear of the functionalized ship and that is open to the rear of the functionalized ship and configured to be submerged at least in part, such that the marine or underwater drone is able to enter into said removable module to dock in the longitudinal sagittal maneuvering area or exit therefrom, the marine or underwater drone docking and exiting through the rear of the functionalized ship such that the marine or underwater drone is able to be launched to water and recovered on the marine or underwater ship by passing through the longitudinal sagittal maneuvering area,
• wherein the removable module is selected from one of:
• (i) a first removable module comprising, in the longitudinal sagittal maneuvering area, a plane that is inclined from the rear and the bottom to the top and the front, the inclined plane of said removable module inserted in the base ship having its rear end submerged and its front end out of water when the removable module is in the water,
• (ii) a second removable module comprising, in the longitudinal sagittal maneuvering area, a lift platform configured to move between a submerged lower position of reception or launching of the marine or underwater drone and an upper position, out of water, substantially flush with at least one of the two rear lateral deck parts of the base ship when the removable module is in the water, and
• (iii) a third removable module comprising, in the longitudinal sagittal maneuvering area, a tilting launch ramp configured to tilt between an inclined position where the rear of the ramp is submerged and the front is out of water and a horizontal position where the ramp is totally out of water when the removable module is in the water.
