  • the radio antenna of the known torpedo is, for example, telescopically formed and has such a length in order to be able to reach the water surface in the submerged state of the torpedo, in order to do so to establish a communication link or at least to be able to receive data from a satellite-based navigation system.
  • the torpedo is guided to the destination area.
  • the torpedo can also transmit current and / or previously stored data to a control center via the radio antenna.
  • the control center receives precise data of the target torpedo, which is useful for the location information in the control center.
  • the torpedo can also receive new data via the communication link, eg new target data or shutdown commands.
  • the torpedo travels close to the surface of the water and extends the radio antenna so far that it is in the overwater area and can build up an undisturbed radio link. Due to the telescopic design of the radio antenna, a relative to the caliber of the torpedo significantly increased extension length of the radio antenna can be provided so that a breakthrough of the torpedo is prevented by the water surface. Nevertheless, the contact by extending the radio antenna is a sensitive event, in which it must be avoided that the torpedo betrays or can be located when approaching the target by the extension and retraction of the radio antenna in shallow water. The lowest possible retraction and extension of the radio antenna must be ensured even after several operations of the radio antenna. In addition, the radio antenna must be smoothly retractable and retractable even after prolonged storage of the torpedo.

  • the antenna cable may be formed in a portion of the interior as a spiral cable, which is short in the relaxed state and expands at train during the extension of the radio antenna.

  • the telescopic cylinder moves synchronously with the movement of the cable drum, since the constant tensile force in the pull rope prevents uncontrollable, rapid export movement due to the pneumatic actuation of the telescopic cylinder.
  • the cable drum is drivable via a self-locking gear, whereby the cable drum is movable exclusively by actuation via the drive means, since the self-locking of the gear teeth counteracts movement of the transmission due to cable forces on the cable drum. This ensures a standstill of the cable drum, if no drive, and precluded an uncontrolled movement of the cable drum.
