Prototype/PR.1 Prototype and first few photo-reconnaissance aircraft. Easily distinguishable by short engine nacelles. Two Rolls-Royce Merlin 21 engines with two speed, single stage superchargers and De Havilland hydromatic propellers.
F.II Fighter. Developed from prototype W4052. Four 20mm cannon and four.303in Browning machine guns. Rolls-Royce Merlin 21 and 23 engines. Two were built experimentally with a rotating dorsal turret equipped with four .303in machine guns. Some examples converted to PR.II.
B.IV Unarmed bomber. Like the PR.1 but with longer engine nacelles. Rolls-Royce Merlin 21 and 23 engines. Capacity for four 500lb bombs (with shortened fins) in the fuselage in place of the four 250lb bombs in the original design. Later modified to carry a 4000lb bomb (blockbuster or "cookie") with a bulged bomb-bay. The first operational sorties were made in daylight to Cologne. The first bombing of Berlin by daylight was made by B.IV's on 30th January 1943.
FB.VI Fighter bomber. Developed from the NF.II with Rolls- Royce Merlin 22, 23 and 25 engines. Same armament as the NF.II plus two 50 gallon jettisonable wing tanks or two 500lb bombs (or extra tankage in the fuselage behind the cannon). Provision was made in 1944 to carry four 60lb rockets under each wing in place of the wing tanks or bombs for attacks on shipping. Two Mk.6 Mosquitos were modified for deck landing and converted to Sea Mosquitos by adding an arrestor hook, strengthening the rear fuselage and fitting four bladed propellers, becoming the basis for the Mk.33.
Voila déja de quoi comparer les version proposées, et c'est ici:

Sinon, pour les moteurs, tous des merlins de la série XX, du 21 au 25.
J'ai des chiffres pour la puissance, mais je ne suis pas certain de leur fiabilité.
Le FBVI est plus lourd de + ou - 600kg à vide, et le poid en charge est quasi idem.
