Abstract

To provide an underwater vessel, an expansion recovery system for the underwater vessel, and an expansion recovery method for the underwater vessel capable of easily expanding and recovering.SOLUTION: An underwater vehicle is configured to: deploy an underwater vehicle 1 underwater in a state of integrating a floating unit 1B and a body unit 1A of the underwater vehicle 1; float the floating unit 1B and a communication device 3 to the water surface in a state of connecting the floating unit 1B and the body unit 1A by a cable body 1C by separating the floating unit 1B on which the communication device 3 is mounted from the body unit 1A of the underwater vehicle 1 when recovering the underwater vehicle 1; and make the underwater vehicle 1 into a state of being captured by a recovery device 50 by making a boat towing device 20 to which the recovery device 50 is connected approach the floating unit 1B floating on the water surface and hooking the cable body 1C or the floating unit 1B to the recovery device 50. Then, the underwater vehicle 1 is recovered by towing the recovery device 50 in a state of capturing the underwater vehicle 1 up to a recovery target water area by the boat towing device 20.SELECTED DRAWING: Figure 2
