Den Lockheed Hudson var et amerikansk bygget let bombefly og kystrekognosceringsfly bygget oprindeligt til Royal Air Force kort før udbruddet af Anden Verdenskrig og primært opereret af RAF derefter. Hudson var den første betydelige flykonstruktionskontrakt for Lockheed Aircraft Corporation - den oprindelige RAF-ordre på 200 Hudsons overgik langt enhver tidligere ordre, virksomheden havde modtaget. Hudson gjorde tjeneste under hele krigen, hovedsageligt ved kystkommandoen, men også i transport- og træningsroller samt ved at levere agenter ind i det besatte Frankrig. De blev også brugt i vid udstrækning med Royal Canadian Air Force's anti-ubådseskadriller og af Royal Australian Air Force.
Den Lockheed Hudsonwas a military conversion of the Lockheed Model 14 Super Electra airliner. When the British Royal Air Force realized they lacked a modern maritime patrol aircraft at the start of WWII, they turned to the United States. The Hudson became the first American-built aircraft to see significant service with the RAF. Though it retained its airliner roots—including its “pregnant” fuselage and comfortable cabin—it was a fast, capable, and rugged platform that scored the RAF’s first aerial victory of the war and became the scourge of the German U-boat fleet.

Design Engineering: From Luxury to Lethality
The Boulton Paul Turret:The most significant modification for British service was the addition of a Boulton Paul power-operated dorsal turret near the tail. This gave the Hudson a defensive “sting” that often surprised German interceptors.
Fowler Flaps:Inherited from the Super Electra, the Hudson featured large-area “Fowler” flaps. These allowed the heavy, twin-engine aircraft to take off and land on relatively short, unimproved coastal airfields.
The Bomb Aimer’s Nose:The luxury nose of the airliner was replaced with a heavily glazed “stepped” nose for the bomb aimer and navigator, providing excellent visibility for spotting submarine periscopes or navigating over featureless oceans.
Internal Bomb Bay:Lockheed designers successfully integrated a bomb bay into the lower fuselage without compromising the aircraft’s structural integrity, allowing it to carry depth charges or standard 250 lb bombs.
Coastal Command Heroics
First Kill:A Hudson of No. 224 Squadron RAF achieved the first British aerial victory of the war on September 8, 1939, when it downed a Dornier Do 18 flying boat over the North Sea.
U-Boat Capture:In August 1941, a Hudson famously attacked the German submarineU-570. After being damaged by depth charges, the U-boat crew actually surrendered to the aircraft—the first time a submarine ever surrendered to a plane.
“Old Faithful”:RAF crews nicknamed the plane “Old Faithful” due to its ability to take heavy punishment and return home on a single engine. Its Wright Cyclone engines were famously reliable over long trans-oceanic patrols.
Special Duties:Because of its civilian airliner DNA, the Hudson was quiet and inconspicuous. It was frequently used by the RAF “Special Duties” squadrons to drop SOE agents and supplies into occupied France under the cover of night.
