German Naval Officers at Ostend Presiding Over a Submarine, 1918

This rare photograph captures a group of German naval officers standing on the deck of a submarine at Ostend in 1918, during the final year of the First World War. Ostend, along with nearby Zeebrugge, was a crucial base for German U‑boat operations in the English Channel and the North Sea.

Images of submarines from this period are uncommon, making this photograph a valuable glimpse into the daily routines and working conditions of the Imperial German Navy.

Life On Board a German U‑Boat in 1918

By 1918, German submarines — or U‑boats — had become one of the most feared weapons of the war. Their ability to strike unseen beneath the waves changed naval warfare forever. This photograph shows the submarine surfaced at harbour, giving a rare view of the crew in daylight rather than the cramped, dim interior where they spent most of their service.

The officers appear relaxed but purposeful, suggesting a moment of routine inspection or preparation. Submarine crews were highly trained specialists, responsible for navigating, maintaining machinery, and operating the vessel’s weapons under extreme pressure.

Weapons and Equipment on Deck

At one end of the deck, a crewman grips the cranking handle of a machine gun mounted on the submarine. Although U‑boats were primarily designed for underwater attacks using torpedoes, deck guns and machine guns were essential when engaging smaller vessels or defending the submarine while surfaced.

Torpedoes remained the submarine’s chief offensive weapon, capable of crippling or sinking large ships with a single strike. However, the deck armaments allowed the crew to conserve torpedoes when confronting lightly armed targets.

Naval Officers at Work: Maintenance on the Gangplank

On the gangplank, a group of German naval officers can be seen performing maintenance work. Submarines required constant inspection and repair, especially after long patrols in harsh sea conditions. Even small mechanical issues could become life‑threatening once submerged.

The officers’ presence on deck suggests a moment of preparation — perhaps before a patrol, or immediately after returning from one. Their uniforms and posture reflect the discipline and hierarchy typical of the Imperial Navy.This photograph shows German naval officers on deck of a submarine at Ostend in 1918.
