The first use of the "Marinefährprahm" was during Operation Barbarossa, the German invasion of the Soviet Union. Twelve "Marinefährprähme" were deployed during Operation Beowulf II as part of the German invasion of Saaremaa, Hiiumaa and Muhu on 14 September 1941. The "Marinefährprahm" provided logistical support during the siege of Sevastopol in June 1942. Twenty-four "Marinefährprähme" from "1. Landungs-Flotille" transported a "Kampfgruppe" from the 46th Infantry Division across the Kerch Strait to the Taman Peninsula as part of Operation Blücher II on the night of 2 September 1942.
