Aircraft History

Lockheed Hudson

No. 11 Bomber Reconnaissance (BR) Squadron was the first Royal Canadian Air Force (RCAF) squadron to take delivery of the Hudson when it formed at RCAF Station Rockcliffe (Ottawa) in Oct 1939. The squadron moved to RCAF Station Dartmouth a month later where it flew anti-submarine and convoy escort patrols until the end of the war (the squadron converted from Hudsons to Liberators in July 1943). No. 11 (BR) was the only squadron, while based at Dartmouth, to attack an German U-boat that resulted in any damage. On 23 June 1942 a No. 11 BR Hudson, piloted by P/O W. Graham, sighted U-87 (a type VII B submarine) on the surface, dead in the water, just south of Halifax. Graham turned to make a stern attack directly out of the sun, which was just rising above the thin layer of patchy fog. The submarine was in the process of diving with only the upper part of the conning tower and the stern awash when Graham released his four depth charges. The depth charges undershot U-87 (astern) but were close enough to shear some of the bolts that held the diesel engines and air compressors to their mountings and break generators loose. U-87 limped home only to be sunk on 4 March 43 by two Royal Canadian Navy ships, the corvette HMCS Shediac and the destroyer HMCS St. Croix, at 4136N 1331W, 220 miles west of Portugal.
