The Vernon was a development of the Vickers Vimy Commercial, a passenger variant of the famous Vickers Vimy bomber, and was powered by twin Napier Lion engines or Rolls-Royce Eagle VIII engines.[1] 55 were built.

In February 1923, Vernons of Nos. 45 and 70 Squadrons RAF airlifted nearly 500 troops to Kirkuk, Iraq[2] after the civilian area of that town had been overrun by Kurdish forces. This was the first-ever[3] strategic airlift of troops.

Vernons of No. 45 Squadron had bomb racks and sights fitted.[4] In May 1924 the squadron was officially designated No. 45 (Bombing) Sqdn.[5]

Vernons were replaced by Vickers Victorias from 1927.
