Editing Vickers Wellington (section)

===Experimental and conversion variants===
;Type 298 Wellington Mark II prototype: one aircraft L4250; powered by two 1,145&nbsp;hp (854&nbsp;kW) Rolls-Royce Merlin inline piston engines.

;Type 299 Wellington Mark III  prototype: two only.

;Type 410 Wellington Mark IV prototype: Serial R1220; powered by two Pratt & Whitney Twin Wasp radial piston engines.

;Type 416 Wellington (II): The original Wellington II prototype was converted with the installation of a 40&nbsp;mm (1.57&nbsp;in) [[Vickers S gun]] with predictor gunsight in the dorsal position. This was the planned armament to be mounted in the nose of the Vickers Type 414 twin-engined  fighter for which the Air Ministry raised specification F22.39. The armament was first flown on 25 October 1940 and test fired 8 November.{{Sfn|Buttler|2004|p=43}}

;Type 418 Wellington DWI (Detonation Without Impact) Mark I: Conversion of four Wellington Mark IAs to [[minesweeper (ship)|minesweeping]] aircraft for exploding magnetic mines. Fitted with Ford V-8 petrol engine and Mawdsley [[electrical generator]] to induce [[magnetic field]] in a {{convert|48|ft|m|abbr=on}} diameter loop mounted under fuselage. They had a solid nose with a bracket supporting the loop, which was also supported under the rear fuselage and the wings, outboard of the engines. DWI was also known as "Directional Wireless Installation" – to mislead the true purpose of the loop.

;Type 419 Wellington DWI Mark II: DWI Mark I aircraft upgraded by installation of [[de Havilland Gipsy Six]] engine for increased generation power. 11 aircraft were converted to this standard. They were operated by No. 1 General Reconnaissance Unit, RAF, sweeping mines in the Thames Estuary for a short time until the Royal Navy had an equivalent capability to sweep magnetic mines. The unit was transferred to Egypt for use in the Suez Canal.<ref>''From Bouncing Bombs to Concorde – The Authorised Biography of Aviation Pioneer Sir George Edwards OM'', Robert Gardner 2006, {{ISBN|0750943890}}, p. 28</ref>
