Major changes were incorporated into the B-26 design beginning with the block 10 B model (and block 5 C model). The wing span was increased from 65 to 71 feet to decrease the high wing loading and improve the handling of the aircraft, particularly at landing speeds. The wing was also modified by adding flaps outboard of the engine nacelles to further improve take off and landing performance. The vertical stabilizer was heightened by 20 inches to 21 feet, 6 inches and made the late model B-26s easily distinguished from the "short tail" early models.

Like the B-25, the forward armament of the B-26 was increased for ground strafing missions. The nose featured one fixed and one flexible .50-cal. machine gun while four fixed fuselage-mounted .50-cal. package guns were added just behind and below the cockpit.

Differences between late production B models included a switch from manually operated tail guns to powered types, relocation of the waist gunner positions and various engine cowling changes. Many aircraft were modified in the field incorporating improvements from later model production. Armor plating was added to the aircraft's exterior just below and slightly forward of the wind screen to protect the pilot and co-pilot. Block 45 and later B-26Bs had a larger windscreen designed for better forward visibility.

1,883 B-26Bs were built; 1,242 of these were block 10 or later.
