The invention provides a low-noise high-navigational-speed large-depth underwater unpowered upwards-floating test platform. The low-noise high-navigational-speed large-depth underwater unpowered upwards-floating test platform comprises a non-watertight outer shell, a floating force device, an electronic cabin, a release mechanism and a stern force bearing rod, wherein the floating force device is composed of a plurality of pressure withdrawing hollow floating balls and a floating ball outer frame; the non-watertight outer shell is composed of a bow end, a parallel middle body and a stern; the multiple pressure withdrawing hollow floating balls are fixedly embedded into the floating ball outer frame, and the floating ball outer frame is fixed to the interior of the parallel middle body; the electronic cabin is fixed to the interior of the stern through a flange, a sensor and a data collecting device are loaded inside the electronic cabin, and a depth sensor is loaded outside the electronic cabin; one end of the stern force bearing rod is fixedly connected to the electronic cabin, and the other end of the stern force bearing rod is fixedly connected with the tail end of the stern of the outer shell; and the release mechanism is composed of a weight and a releaser, and the weight is connected with the other end of the stern force bearing rod through the releaser. The test platform can serve as an underwater structure flow-induced near-field or a far-field noise test verification platform.
