HMS P222 was a S-class submarine of the third batch built for the Royal Navy during World War II. She was probably sunk by an Italian ship in 1942.
HMS P222 Wikipedia
The third batch was slightly enlarged and improved over the preceding second batch of the S-class. The submarines had a length of 217 feet (66.1 m) overall, a beam of 23 feet 9 inches (7.2 m) and a draft of 14 feet 8 inches (4.5 m). They displaced 842 long tons (856 t) on the surface and 990 long tons (1,010 t) submerged. The S-class submarines had a crew of 48 officers and ratings. They had a diving depth of 300 feet (91.4 m).
For surface running, the boats were powered by two 950-brake-horsepower (708 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 15 knots (28 km/h; 17 mph) on the surface and 10 knots (19 km/h; 12 mph) underwater. On the surface, the third batch boats had a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 10 knots (19 km/h; 12 mph) and 120 nmi (220 km; 140 mi) at 3 knots (5.6 km/h; 3.5 mph) submerged.
P222 was armed with six 21-inch torpedo tubes in the bow. She carried six reload torpedoes for the bow tubes for a grand total of a dozen torpedoes. Twelve mines could be carried in lieu of the torpedoes. The boat was also equipped with a 3-inch (76 mm) deck gun.
HMS P222 built by Vickers Armstrong and launched on September 20, 1941. She was initially assigned to the naval base at Gibraltar to guard the entrance to the Mediterranean. On 27 July 1942 P 222 intercepted the Vichy French merchant Mitidja off Cape Palos, Spain. The Mitidja was boarded by the V-class destroyer HMS Wrestler and escorted to Gibraltar.
P222 left Gibraltar to patrol off Naples on 30 November 1942. She sent a number of messages on 7 December but after that date no further communication was made. She failed to arrive at Algiers on her due date and was reported overdue on 21 December 1942. The Italian torpedo boat Fortunale claimed to have sunk a submarine with depth charges on 12 December, south-east of Capri. This remains the most probable cause of the submarine’s loss but there has been no confirmation. Since she was sunk before her name could be formally assigned, she is known by her pennant number, P222.
