The Vickers Aircraft Vernon was a twin-engine biplane bomber-transport aircraft, derived from the Vickers Vimy Commercial and Vimy Ambulance. It was used by 45 Sqn and 70 Sqn Royal Air Force in the Middle East, entering service in 1921.
 
Initially, power was supplied by two 360 hp Rolls-Royce Eagle VIII engines whilst in later aircraft (Vernon II & III), power was provided by 450 hp Napier Lion II or III engines. A total of fifty-five Vickers Vernon aircraft were built, together with the five earlier Vimy Ambulances that were converted to Vickers Vernon standard.
 
The first twenty aircraft (J6864 – 6883) were Vickers Vernon Mk1s with the Rolls-Royce Eagle VIII. These were then followed by twenty-five Vickers Vernon IIs (J6884 – 6893, J6976 - 6980, and J7133 - 7142) powered by the 450 hp Napier Lion I engine.
 
The final ten aircraft (J7539 - 7548) were to Vickers Vernon III standard, powered by the geared Napier Lion III engines and fitted with long range tanks.
 
Although originally intended as a troop transport, Vickers Vernon aircraft were converted 'in-service' with under-wing bomb racks to deter local uprisings, particularly in Iraq.
 
The type also contributed to the opening of civil air routes in the area, with the setting up of a desert air route between Amman (Jordan) and Ramadi (in Central Iraq). This led to RAF aircraft also carrying civil mail along this route, from its inauguration.

To aid navigation over the desert, a so-called ‘Bradshaw track’ was ploughed in the desert. Emergency landing grounds were also created along the track, marked with letters and numbers to aid navigation. The route became both reliable and successful, with performance under the desert conditions being further improved with the introduction of the Lion-powered Vernon II and III engines
 
In February 1923, Vickers Vernon's of Nos. 45 and 70 Squadrons RAF airlifted nearly 500 troops to Kirkuk in Iraq, after the civilian area of that town had been overrun by Kurdish forces. This was the first-ever recorded strategic airlift of troops during conflict. Vickers Vernon's were also used to evacuate troops suffering from dysentery from outlying detachments in Iraq, carrying them for treatment at hospitals in Baghdad. Some 161 patients were transported within fifteen months during 1924 – 25.
 
The Vickers Vernon II underwent trials in January 1922, quickly becoming the standard production version of the type.
 
Other developments included the introduction of an oleo-sprung undercarriage and the final variant (Vickers Vernon III) could be easily distinguished by the elimination of the nosewheel fitted to the earlier marks.
 
The Vickers Vernon was eventually replaced in RAF service by the Vickers Victoria from 1927.
