PR.I: Unarmed photo reconnaissance. F.II: Night fighter. Pilot and observer sit side by side. Flat, bullet resistant windscreen, extended engine nacelles (standard for later versions). Armament consists of four 20mm Hispano cannon under cockpit with 300 rounds per gun and four .303 in. Brownings mounted in nose with 2000 rounds per gun. Subsequently fitted with A1 Mk IV or V Radar or Turbinlight searchlight. T.III: Dual-Control trainer. Most produced after war's end. B.IV: Unarmed bomber version. Internal bomb bay carrying four 500 lb. (227 kg.) bombs. Entered squadron service with 105 Squadron at Swanton Morley November 1941. First operational sortie on May 31, 1942 against Cologne. Some aircraft later fitted with bulged bomb bays for 4,000 lb. (1814 kg.) bomb. FB.VI: Fighter-Bomber and Intruder (Day and Night). Same gun armament as F.II but also carried two 250 lb. (113 kg.) bombs in rear bay and two more on wings (eventually increased to 500 lb.). Alternatively, 50 or 100 gal. drop tanks, mines, depth charges or eight 60 lb. rockets could be fitted to wing stations. Some aircraft were fitted with AI radar. Total production: 2,584. This variant was the most numerous. B.VII: Canadian built Mk. IV, used in North America only. PR.VIII: Photo reconnaissance version of B.IV with supercharged Merlin 61. Mk. IX: Significant redesign with two-stage supercharged Merlin engines, paddle type propellors, bulged bomb bay to accept a 4,000 lb (1814 kg.) bombs or additional fuel cell. New avionics were also installed (Rebecca, Boozer, Oboe or H2S Mk. VI). NF.XII: Conversion of F.II fitted with thimble nose containing AI Mk. VIII centrimetric radar in place of Brownings. NF.XIII: Similar to Mk. XII but built as new. Fitted with thimble or bull nose and same wing as Mk. VI for drop tanks or other stores. NF.XV: High-Altitude fighter with extended wing span (59 ft.), pressurised cockpit, lightened structure, AI Mk. VIII radar in nose and four .303 brownings replacing 20mm cannon in belly pack. Built to engage Ju-86P high altitude raiders. Mk. XVI: Equipped with supercharged Merlins, bulged bomb bay and a pressurised cockpit, the Mk. XVI was built as the PR.XVI and the B.XVI, with over 1,200 of the later being used for high altitude nuisance raids with 4,000 lb. bombs. |
NF.XVII: Night fighter with AI Mk. X or SCR.720 radar. Some aircraft equipped with
tail-looking scanner also. Four 20mm cannon with 500 rounds per gun. FB.XVIII: Developed as a multi-role coastal command fighter. Equipped with a 57mm six-pounder Molins gun with 25 rounds, four Brownings, as well as eight 60 lb. rockets or bombs. Known as Tse-Tse fly for unknown reasons.

PR.41: Australian built derivative of PR.IX and Mk. 40. T.43: Australian trainer. All Australian versions had Packard engines. |
| Comments: Originally concieved of as a unarmed daylight high-speed bomber that utilized non-strategic materials, primarily wood. The aircraft was almost never built since the Air Ministry showed almost no interest in the design and suggested that de Havilland use the production capacity to produce wings for exsisting bombers. de Havilland persisted and eventually was allowed to built the PR.1, since the Air Ministry thought reconnaissance would be the only suitable purpose. From this inauspicious start a legend was born. The Mosquito is one of the most famous twin-engined aircraft to come out of WWII and proved to be a thorn in the Luftwaffe's side almost from the beginning. Not until the Me 262 entered service did the Luftwaffe have an aircraft that could easily intercept the extremely fast Mosquito. Before then the type could for the most part range with impunity over German occupied territory and indeed over the heart of Germany itself. The German's even tried to make there own version with the design of the Ta 154 Moskito, a solid design that never saw service in significant numbers due to production problems. The Moskito proved to be a succesful nightfighter but one of it's most inportant roles was as a counter-nightfighter. Nightfigher Mosquitos would patrol around the RAF's bomber streams and hunt the Luftwaffe nightfighters that proved so destructive. Once these Mosquitos entered service the Luftwaffe nightfighters no longer owned the night. The Mosquito was produced in Britain, Canada and Australia and saw combat in all theaters of the war. Unfortunately the wooden construction of the aircraft left it vulnerable to rot in certain tropical areas but for the most part the type served admirably. |
