The Armstrong Whitworth Atlas was the Royal Air Force's standard army support aircraft of the late 1920s and early 1930s. It was a single-engine, two-seat biplane.

development

The first flight probably took place on May 10, 1925. After successful tests in November 1925, it was decided to procure the aircraft. The takeover of the prototype J8675, previously G-EBLK, took place in 1927. In addition to the version for army support, there was a training aircraft with double controls.

commitment

The Atlas flew with five Army Support Squadrons in Great Britain and with the 208 Squadron in Egypt. At home it was replaced by Hawker Audax until 1934. In Egypt, the aircraft was used until 1935. The training aircraft were retired in 1935/1936.
