V Seehund (nemško "pečat"), znan tudi kot tip XXVII, je bila podmornica, ki jo je med drugo svetovno vojno proizvajala nacistična Nemčija. Zasnovana je bila leta 1944 in jo je upravljala dvočlanska posadka, uporabljala jo je Kriegsmarine (nemška mornarica) v zadnjih mesecih vojne, potopila devet trgovskih plovil in poškodovala dodatne tri, izgubila pa je 35 čolnov, večinoma zaradi slabega vremena. Francoska mornarica je po vojni do leta 1953 uporabljala tri zajete čolne.

General Characteristics and Role

The Seehund (“Seal” or “Sea Dog”), designated Type XXVIIB, was the most successful German midget submarine of World War II, seeing action in the final months of the conflict (1944–1945). Designed under the direction of Dr. Fischer and Grim, the Seehund was engineered from the start as a true small submarine, incorporating the lessons learned from earlier, less effective midget types. Its small size and quiet, slow-speed electric drive made it extremely difficult for Allied radar and sonar (Asdic) to detect, optimizing it for stealthy coastal operations and hit-and-run attacks against Allied shipping in the English Channel and the North Sea.

Armament and Service Record

Armament: 2 x 21-inch (533 mm) G7e torpedoes, carried externally in fixed racks below the hull.
Production: Approximately 285 units were completed before the end of the war, though over 1,000 were originally ordered.
Combat Effectiveness: Despite the late introduction, the Seehund was the most effective German midget submarine. In 142 sorties between January and April 1945, they sank 8 Allied ships (totaling over 17,000 gross tons) and damaged three others.
Post-War Use: Several captured Seehund submarines were used by the French Navy until 1953 for testing and training.
