Role	Dwergonderzeeër
Geproduceerd	1944–1945
Gebouwd	285

De Seehund (Duits: "zegel"), ook bekend als Type XXVII, was een dwergonderzeeër vervaardigd door nazi-Duitsland tijdens de Tweede Wereldoorlog. Ontworpen in 1944 en geëxploiteerd door tweemansbemanningen, werd het gebruikt door de Kriegsmarine (Duitse marine) tijdens de laatste maanden van de oorlog, waarbij negen koopvaardijschepen tot zinken werden gebracht en nog eens drie werden beschadigd, terwijl het 35 boten verloor, meestal toegeschreven aan slecht weer. De Franse marine gebruikte drie veroverde boten na de oorlog tot 1953.

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.

Year Introduced	1944 (Operational January 1945)
Bemanning	2 (Commander and Engineer)
Lengte	11.86 m (38 ft 11 in)
Beam	1.7 m (5 ft 7 in)
Displacement (Submerged)	17 long tons (17.3 tonnes)
Maximum Diving Depth	30 m (98 ft) (Safe operational depth)

Propulsion and Performance

Propulsion: Diesel-electric system.
Surfaced Engine: 1 x Büssing 6-cylinder diesel engine (60 hp).
Submerged Motor: 1 x AEG electric motor (25 hp).
Maximum Speed (Surfaced): 7.7 knots (14 km/h).
Maximum Speed (Submerged): 6 knots (11 km/h).
Maximum Range (Surfaced): 270 nautical miles at 7 knots (can be extended with external tanks).
Maximum Range (Submerged): 63 nautical miles at 3 knots.

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.
