Upon the outbreak of World War II, the sultan of Oman declared war on Germany on September 10, 1939. During the war, Oman had a strategic role in the defence of the United Kingdom's trade routes. Oman was never attacked during the war. In 1943, the Royal Air Force established stations on Masirah Island (RAF Masirah) and at Ras al Hadd. Air-sea rescue units were also stationed in Oman. No. 244 Squadron RAF flew Bristol Blenheim V light bombers and Vickers Wellington XIIIs out of RAF Masirah on anti-submarine duties in the Gulf of Oman and the northern Arabian Sea, while No. 209 Squadron RAF, No. 265 Squadron RAF, and No. 321 Squadron RAF flew Consolidated PBY Catalinas out of Umm Ruşayş on Masirah Island. On October 16, 1943, the German U-Boat U-533 was sunk in the Gulf of Oman after being struck by depth charges dropped by a Bristol Blenheim from No. 244 Squadron RAF. The wreck settled at a depth of 108 meters (354 feet) approximately 25 nautical miles (46 kilometres) off the Fujairah coast. 52 crew members died, with the sole survivor, Matrosengefreiter Günther Schmidt, taken aboard HMIS Hiravati near Khor Fakkan and made a prisoner of war. The wreck is now a popular recreational diving site.
