The Wolfchen
The Wölfchen (meaning wolf cub or little wolf) was a Friederichshaven Type E33 2 x seater sea plane stowed aboard the Raider Wolf. Capable of being dismantled and stowed below when not required, Wölfchen was very successful, routinely being used for reconnaissance missions and often directing the raider onto her victims.
It was the first aircraft to actually capture not one, but two ships (s.s. Wairuna and the schooner Winslow), and undertook at least one night landing at sea without flares.
Fittingly, Wölfchen survived the entire voyage, launching to overfly the Wolf on the raider's triumphant return to Kiel on 24 February 1918.
