HMS D3 was one of eight D-class submarine built for the Royal Navy during the first decade of the 20th century.
The D-class submarines were designed as improved and enlarged versions of the preceding C class, with diesel engines replacing the dangerous petrol engines used earlier. D3 and subsequent boats were slightly larger than the earlier boats. They had a length of 164 feet 7 inches (50.2 m) overall, a beam of 20 feet 5 inches (6.2 m) and a mean draught of 11 feet 5 inches (3.5 m). They displaced 495 long tons (503 t) on the surface and 620 long tons (630 t) submerged. The D-class submarines had a crew of 25 officers and other ranks and were the first to adopt saddle tanks.
For surface running, the boats were powered by two 600-brake-horsepower (447 kW) diesels, each driving one propeller shaft. When submerged each propeller was driven by a 275-horsepower (205 kW) electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 9 knots (17 km/h; 10 mph) underwater. On the surface, the D class had a range of 2,500 nautical miles (4,600 km; 2,900 mi) at 10 knots (19 km/h; 12 mph).
The boats were armed with three 21-inch (53.3 cm) torpedo tube, two in the bow and one in the stern. They carried one reload for each tube, a total of six torpedoes.
D3 was laid down on 15 March 1910 by Vickers at their Barrow shipyard and commissioned on 30 August 1911. During her career, D3 returned from the second Heligoland Bight patrol along with D2, E5 and E7.
