The Lockheed Hudson (US designation: A-28 , A-29 , PBO-1 , AT-18 ) was a twin-engine light bomber and coastal reconnaissance aircraft of the Second World War from American production.
history
Based on the Lockheed 14 Super Electra , Lockheed developed a light bomber that was ordered by the British Royal Air Force for Coastal Command in June 1938 . The first machine, whose series was designated as the Hudson Mk. I, flew on December 10, 1938. In the summer of 1939, the machines were assigned to the Coastal Command. In the following years almost 2000 machines of the Mk. I, Mk. II and Mk. III series were delivered to the Royal Air Force.
The aircraft was mainly used by the Coastal Command, then by the US Navy , the USAAF and the Air Forces of Canada , Australia , New Zealand , Brazil , Ireland , China , the Netherlands , Portugal and South Africa .
A Royal Air Force Hudson was the first Allied aircraft to take off from the British Isles during World War II and shot down a German aircraft (a Dornier Do 18 over Jutland on October 8, 1939 ). When the Allies were shot down earlier, the aircraft had taken off in France or from an aircraft carrier . Hudsons were also involved in the attack on the Altmark and in the hijacking of the German submarine U 570 . A British Hudson also succeeded in sinking a German submarine using missiles for the first time in May 1943 .
In 1942 the first machines, now designated as A-28 , were delivered to the USAAF . By 1942, 82 A-28 and 418 A-29 were produced. There were also 300 AT-18 trainers and 20 machines that were flown by the US Navy as PBO-1s . A Navy PBO-1 was also the first US aircraft to sink a German submarine ( U 656 off the coast of Newfoundland on March 1, 1942).
