A tough attack bomber


A completed A-20 being pulled from the assembly line at the Long Beach, California, factory.

The A-20 was a conventional stressedskin aluminium alloy semi-monocoque aircraft, with single-spar wings, and a two-spar horizontal fin and tailplane. Rudder, elevators and ailerons were fabric-covered, the tailplane having a marked dihedral to clear the airflow from the nacelles.

The original design was very clean, the engine nacelles being completely without excrescence.
