HMS Sturgeon was an S-class submarine that entered service in 1932. The submarine saw service in the Second World War and in 1943 was transferred to the Royal Netherlands Navy as HNLMS Zeehond. Zeehond was returned to the Royal Navy following the war and was sold for scrap in 1946. She was one of the four submarines that formed the First Group of the S class, and the only one of these to survive the war.

The S-class submarines were designed as successors to the L class and were intended to operate in the North and Baltic Seas. The submarines had a length of 202 feet 6 inches (61.7 m) overall, a beam of 24 feet (7.3 m) and a mean draft of 11 feet 11 inches (3.6 m). They displaced 730 long tons (740 t) on the surface and 927 long tons (942 t) submerged. The S-class submarines had a crew of 38 officers and ratings. They had a diving depth of 300 feet (91.4 m).

For surface running, the boats were powered by two 775-brake-horsepower (578 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 650-horsepower (485 kW) electric motor. They could reach 13.75 knots (25.47 km/h; 15.82 mph) on the surface and 10 knots (19 km/h; 12 mph) underwater. On the surface, the first-batch boats had a range of 3,700 nautical miles (6,900 km; 4,300 mi) at 10 knots (19 km/h; 12 mph) and 64 nmi (119 km; 74 mi) at 2 knots (3.7 km/h; 2.3 mph) submerged.
