Hudson II from the Australian Air Forces, 1943.

The Lockheed Hudson was the first American aircraft to be used operationally by the RAF during World War II. It was designed to meet a British requirement for a martime patrol/navigational trainer aircraft. The first 200 aircraft arrived in England in February 1939, with about 1500 total procured before introduction of the Lend-Lease program. In USAAF service the various versions served as troop transports, bomber crew trainers, photo-reconnaissance aircraft, anti-submarine patrol aircraft, trainers for ai r gunners, and as a target tug. Twenty examples were used by the U.S. Navy as maritime patrol aircraft under the designation PBO-1. In all, 2941 Hudsons were built, and many remained in service in a secondary role until the end of the war.
