Catapult-launched spotter planes like Arado Ar 196 twin-float seaplanes were manned by the so-called Bordfliegergruppen ("shipboard flying group").[33] In addition, Trägergeschwader 186 (Carrier Air Wing 186) operated two Gruppen (Trägergruppe I/186 and Trägergruppe II/186)[34] equipped with navalized Messerschmitt Bf 109T and Junkers Ju 87C Stuka; these units were intended to serve aboard the aircraft carrier Graf Zeppelin which was never completed, yet provided the Kriegsmarine with some air-power from bases on land. Furthermore, five coastal groups (Küstenfliegergruppen) with reconnaissance aircraft, torpedo bombers, Minensuch aerial minesweepers and air-sea rescue seaplanes supported the Kriegsmarine, although with lesser resources as the war progressed.[35]
