HMS Regulus (N88) was a Rainbow-class submarine built for the Royal Navy during the 1930s.


Design and description

The Rainbow-class submarines were designed as improved versions of the Parthian class and were intended for long-range operations in the Far East. The submarines had a length of 287 feet 2 inches (87.5 m) overall, a beam of 29 feet 10 inches (9.1 m) and a mean draft of 13 feet 10 inches (4.2 m). They displaced 1,772 long tons (1,800 t) on the surface and 2,030 long tons (2,060 t) submerged. The Rainbow-class submarines had a crew of 56 officers and ratings. They had a diving depth of 300 feet (91.4 m).

For surface running, the boats were powered by two 2,200-brake-horsepower (1,641 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 660-horsepower (492 kW) electric motor. They could reach 17.5 knots (32.4 km/h; 20.1 mph) on the surface and 9 knots (17 km/h; 10 mph) underwater. On the surface, the boats had a range of 7,050 nautical miles (13,060 km; 8,110 mi) at 9.2 knots (17.0 km/h; 10.6 mph) and 62 nmi (115 km; 71 mi) at 4 knots (7.4 km/h; 4.6 mph) submerged.

The boats were armed with six 21-inch torpedo tubes in the bow and two more in the stern. They carried six reload torpedoes for a grand total of fourteen torpedoes. They were also armed with a QF 4.7-inch (120 mm) Mark IX deck gun.

Construction and career

Regulus was laid down by Vickers-Armstrong at Barrow-in-Furness and launched in 1930. Before Second World War she was stationed with Submarine Flotilla #4 on the China station, based out of Hong Kong.

Regulus (Lt.Cdr. Frederick Basil Currie, RN) left Alexandria to patrol in the southern Adriatic on 23 November 1940. She was lost with her entire crew on 6 December 1940 whilst on patrol off Taranto, Italy. In all probability she hit a mine.
