The Douglas A-26 Invader (designated B-26 between 1948 and 1965) is an American twin-engined light bomber and ground attack aircraft. Built by Douglas Aircraft Company during World War II, the Invader also saw service during several major Cold War conflicts. A limited number of highly modified United States Air Force aircraft served in Southeast Asia until 1969. It was a fast aircraft capable of carrying a large bomb load. A range of guns could be fitted to produce a formidable ground-attack aircraft

The A-26 was Douglas Aircraft's successor to the A-20 (DB-7) Havoc, also known as Douglas Boston. Designed by Ed Heinemann, Robert Donovan, and Ted R. Smith, the innovative NACA 65-215 laminar-flow airfoil wing of the A-26 was the work of project aerodynamicist A.M.O. Smith. The Douglas XA-26 prototype (AAC Ser. No. 41-19504) first flew on 10 July 1942 at Mines Field, El Segundo, with test pilot Benny Howard at the controls. Flight tests revealed excellent performance and handling, but engine-cooling problems led to cowling changes and elimination of the propeller spinners on production aircraft. During testing, the nose wheel was found to be structurally inadequate, thus the nose gear was redesigned and made more structurally sound

After about 1,570 production aircraft, three guns were installed in each wing, coinciding with the introduction of the "eight-gun nose" for A-26Bs, giving some configurations as many as 14 .50 in (12.7 mm) machine guns in fixed forward mounts. An A-26C nose section could be replaced with an A-26B nose section, or vice versa, in a few hours, thus physically (and officially) changing the designation and operational role. The "flat-topped" canopy was changed in late 1944 after about 820 production aircraft, to a clamshell style with greatly improved visibility. Alongside the pilot in an A-26B, a crew member served as navigator and gun loader for the pilot-operated nose guns. In an A-26C, that crew member served as navigator and bombardier , and relocated to the nose section for the bombing phase of an operation. A few A-26Cs were fitted with dual flight controls, some parts of which could be disabled in flight for access to the nose section. Access for the bombardier was through the lower section of the right instrument panel; he normally sat next to the pilot. This was similar to British designs such as the Lancaster , Blenheim / Beaufort , Wellington , etc. A tractor-style "jump seat" was behind the "navigator's seat"

The MB-339 was developed during the 1970s in response to an Italian Air Force requirement that sought a replacement for the service's existing fleet of Aermacchi MB-326s.
