An underwater body having a movable component which can be moved into a retracted position and, as a result, increases the volume of the underwater body. In addition, a method is disclosed for operating such an underwater body. An expansion means conducts a fluid into a hollow space. The hollow space is operatively connected to the movable component. When the fluid is conducted into the hollow space, the movable component is moved into the extended position relative to the shell of the underwater body. The fluid in the hollow space hardens. The hardened fluid in the hollow space holds the movable component in the extended position.

A vehicle capable of taking off and landing vertically and operating in water, land, air and submarine environments includes a fuselage, two main wings, ailerons, a vertical tail, a rudder, a horizontal tail, elevators, a propeller, rotor wings, rotor wing supports, etc. The vehicle has the advantages of adaptability to various environments, good concealment and strong survivability. Compared with a traditional unmanned rotorcraft, the vehicle has longer endurance time and larger load. Compared with a fixed wing UAV, the vertical take-off and landing function makes the work more convenient. Compared with unmanned diving equipment, the vehicle is applicable to richer environments, and can complete designated missions in air, land, water and submarine environments. Compared with a tilt rotor UAV in water, land, air and submarine environments, the vehicle is rapider in switching of various modes and is higher in stability.

A system for navigation of an autonomously navigating submersible body during entry into a docking station below the water surface includes a determiner for determining an actual motion vector of the autonomously navigation submersible body in relation to the set motion vector describing the optimum entry direction into the docking station and a calculating unit. The calculating unit serves to determine the deviation between the actual motion vector and the set motion vector to determine control vectors based on the deviation and to thereby control the autonomously navigating submersible body during entry.

Systems and methods for operating a HAUCS sensing platform. The methods comprise: autonomous travel by a UAAV to a first location in proximity to a body of water (BoW) in accordance with a mission plan; actuating a mechanical device to transition a sensor from a retracted position in which the sensor is adjacent to a UAAV to an extended position in which the sensor resides a given distance from a UAAV; collect, by HAUCS sensing platform and sensor, sensor data concerning a water condition of BoW at different depths; actuating the mechanical device to transition the sensor from the extended position to the retracted position after the sensor data has been collected; causing the sensor data to be processed using a machine learning-based analytical engine to determine whether a water distress condition exists/is predicted to occur; and modifying the mission plan when the water distress condition exists/is predicted to occur.
