When aiming above the centerline of the aircraft, the mirror in the center of the column would flip, showing the gunner what the upper periscope was seeing. Looking into a binocular periscope sight mounted on the column, he controlled the guns with a pair of handles on either side of the column. The gunner sat on a seat facing rearward. In most missions, a third crew member in the rear gunner’s compartment operated the remotely controlled dorsal and ventral gun turrets, using a novel, complex and problematic dual-ended periscope sight, with traversing and elevating/depressing periscope sights on each end. A crew member typically served as navigator and gun loader for the pilot-operated nose guns. The original “flat-top” canopy was changed in late 1944 after about 820 production aircraft, to a clamshell style with greatly improved visibility, which made exiting the cockpit in an emergency much easier than with the earlier canopy. An A-26C nose section could be replaced with an A-26B nose section, or vice versa, in a few man-hours, thus physically and officially changing the designation and operational role. 50-caliber machine guns in fixed forward mounts. The A-26C was equipped with a “glass” nose for a bombardier using a Norden bombsight for medium altitude precision bombing.Īfter about 1,570 A-26s were produced, three machine guns were installed in each wing, rather than the underwing “gun tubs” originally used, which coincided with the introduction of the “eight-gun nose” for A-26Bs thus some “gun nose” A-26s had as many as 14. 50 caliber machine guns it was officially termed the “all-purpose nose”, later commonly known as the “six-gun nose” or “eight-gun nose”. Normal nose armament was originally six and later eight. 50 caliber machine guns, 20mm or 37mm auto cannon, or even a 75mm pack howitzer that was never used operationally. The A-26B had a gun nose, which originally could be equipped with a combination of armament including. The aircraft was originally built in two different configurations. Repeated collapses during testing led to reinforcement of the nose landing gear. Flight tests revealed excellent performance and handling, but engine cooling problems led to cowling changes and elimination of the propeller spinners on production aircraft.
NORDEN BOMBSIGHT EBAY SERIAL
The XA-26 prototype, serial 41-19504, first flew Jat Mines Field, El Segundo, with famed race and test pilot Benny Howard at the controls. After service in World War II, it saw combat in the Korean War and several major Cold War conflicts with both American and other air forces. Smith as a replacement for the Douglas A-20 Havoc light bomber. The Douglas A-26 Invader designated B-26 after 1948, was designed by Ed Heinemann, Robert Donovan, and Ted R.
