The invention relates to an underwater antenna device with a nonstationary antenna, an extension mechanism and a repositioning mechanism, wherein an extending force can be applied in a direction of the extending force by the extension mechanism of the antenna and an opposing force can be applied in a direction of the opposing force, in the opposite direction to the extending force by the repositioning mechanism of the antenna, characterized in that the repositioning mechanism or a part of the repositioning mechanism is designed as selectively nonstationary, so that, by selected changes to the position, the antenna can be positioned in a retracted position, an extended position or an intermediate position.

Underwater antenna device with a non-stationary antenna and underwater vessel

The invention relates to an activation device for an electric battery unit, in particular, for a battery part of a torpedo. The invention also relates to a battery unit with activation devices of this type. An activation device incorporates an operating supply connection, to which an operating supply reservoir can be connected. A movably arranged cutting element can be pneumatically actuated via a pneumatic connection of the activation device by means of an actuation element, wherein a sealing element arranged in the path of travel of the cutting element controls the operating supply connection. In order to guarantee a safe storage, ready for operation, and a safe activation of a battery unit, it is provided in accordance with the invention that the activation device incorporates a pneumatic outlet, which can be fluidically connected to the pneumatic connection, depending on the position of the actuation element.
