Douglas A-26 / B-26 Invader
The Douglas A-26 Invader (designated B-26 between 1948–1965) was a
United States twin-engine light bomber and attack aircraft built by
Douglas Aircraft during World War II that also saw service during
several of the Cold War's major conflicts. A limited number of highly
modified aircraft (designation A-26 restored) served in combat until
1969.
It was found to be a fast aircraft capable of carrying twice its
specified bomb load. A range of guns could be fitted to produce a
formidable ground-attack aircraft.
The redesignation of the type from A-26 to B-26 has led to popular
confusion with the Martin B-26 Marauder, a design that first flew in
November 1940, some 16 months before the Douglas design's maiden
flight. Although both types utilized the much-used Pratt & Whitney
Double Wasp eighteen-cylinder, double-row engine, they are completely
different designs.
