In March 1937 the submarine navigated the Gloucester and Sharpness Canal in the company of H49 whose commander had arranged the trip.[1] During Warship Week March 1942 H33 was adopted by East Dean RDC (Gloucestershire). HMS H33 was scrapped at Troon on 19 May 1944.
Design
Like all post-H20British H-class submarines, H33 had a displacement of 423 long tons (430 t) at the surface and 510 long tons (520 t) while submerged.[2] It had a total length of 171 feet (52 m),[3] a beam of 15 feet 4 inches (4.67 m), and a draught of 12 metres (39 ft).[4] It contained a diesel engines providing a total power of 480 horsepower (360 kW) and two electric motors each providing 320 horsepower (240 kW) power.[4] The use of its electric motors made the submarine travel at 11 knots (20 km/h; 13 mph). It would normally carry 16.4 long tons (16.7 t) of fuel and had a maximum capacity of 18 long tons (18 t).[5]
The submarine had a maximum surface speed of 13 knots (24 km/h; 15 mph) and a submerged speed of 10.5 knots (19.4 km/h; 12.1 mph). Post-H20 British H-class submarines had ranges of 2,985 nautical miles (5,528 km; 3,435 mi) at speeds of 7.5 knots (13.9 km/h; 8.6 mph) when surfaced.[2][4]H33 was fitted with an anti-aircraft gun and four 21 inches (530 mm) torpedo tubes. Its torpedo tubes were fitted to the bows and the submarine was loaded with eight 21 inches (530 mm) torpedoes.[2] It is a Holland 602 type submarine but was designed to meet Royal Navy specifications. Its complement was twenty-two crew members.[2]
