Torpedo Fin

A flat torpedo component made of deformation-resistant material, which is fixed to the outside in parallel to the longitudinal axis of the torpedo. It is attacked by the wake inflow/wake current when the torpedo is in motion and is designed to damp/prevent the roll and to stabilize the straight run of the torpedo. For pivoted/shivel-mounted flat torpedo components designed to generate pitching and/or yawing motions see rudder, torpedo.
