A-28/29 "Hudson"

Attack Aircraft


Lockheed Hudson #EW 874

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.
