Operationally it was expected to use the Enzian in the following manner: Launch it toward and direct it to the target vicinity under radio control using the new German equipment Kogge and either line of sight or radar navigation. When the missile's approach to the target came within the operating range of the particular selfseeking head employed, the latter would assume control and direct the Enzian to the target's proximity on a modified homing course. The proximity fuze at predetermined distance activates the warhead which was designed to ensure maximum coverage and effective damage of the target from 45 meters. (see section on warhead below.) It is considered pertinent to note here that the Germans were doing extensive research work on the theory of homing courses. Their principal investigations appeared to be based on compromises lying between a pure chaser or homing course and a straight interception route procured by interjecting self navigation into the intelligence system.

   Initial planning provided for the Enzian's use of one of several types of homing devices and proximity fuzes currently being developed or combinations of the above. Tests had not progressed beyond operation with the standard German radio control, the 6-meter "Strassburg-Kehl", developed by Telefunken and Strassfurt Rundfunk. The "Kogge" designed by Telefunken to operate on a 24-cm wave length was destined for use in the production Enzians.

   The I.R. device, "Madrid," developed by Kepka of Vienna, an acoustic device developed by Telefunken and Messerschmitt, or an electronic device were projected for use as homing heads. These articles had been laboratory tested by their manufacturers only as seperate entities.

Standard Siemens electric servos are used to actuate the control surfaces.
