G-2 - Cabin pressurisation equipment removed, armed with the original 7.9 mm machine guns. Often employed in the low level reconnaissance role.

G-2/R1 - Fighter bomber version able to carry a fuel tank under each wing and an SC 500 bomb under the fuselage, the ground clearance needed being provided by a jettisonable wheel mounted beneath the rear fuselage.

G-3 - Identical with the G-1 except for the radio fit carried.

G-4 - Unpressurised version of the G-3

G-5 - Armament of two 13mm machine guns and one 20 mm cannon. DB605D engine fitted with MW 50 water and methanol injection to boost power to 1,800 hp for short periods. The water and methanol were carried in a tank below the fuselage.

G-10/U4 - Armament increased with a belly pack containing two 30mm MK 108 cannon. This could be exchanged for a fixed belly fuel tank.

G-10/R2 - Used same wooden tail unit as the G-5. Also fitted with the improved cockpit canopy sometimes known as the "Galland Hood" after Adolf Galland, the German Ace and General of Fighters, but more correctly called the "Erla" cockpit (after the factory that introduced it).

G-10/R6 - New IFF equipment fit.

G-12 - Two seat trainer developed from the G-1.

G-14 - The G-14 carried the smaller calibre 20 mm MG 151 hub cannon together with the two 13mm machine guns. It could be fitted easily with either underwing cannon or rockets and could carry a bomb. Cockpit canopy of the "Galland Hood" type. At least one G-14 was modified to carry a 20mm cannon in the rear fuselage firing upwards in a "Schrage Musik" installation meant for night attacks on British bombers, firing upwards into their bellies.

G-16 - Ground attack aircraft with extra armour protection, it did not reach operational service.

H-0 - Pre-production version modified from F series airframes. The H series was an attempt to produce a high altitude fighter. Wing span was increased by 6ft 6ins by adding a section to the wing root. The tailplane was increased in span and had to be braced to the fuselage. DB 601 engine used.

H-1 - Production version with DB605 engine with the GM 1 power boost system. Armament was one cannon
and two machine guns, although it was hoped to fit an additional two machine guns in the wings. Only a small number were produced, the Luftwaffe favouring the Focke-Wulf Ta 152H design.

H-2 - Proposed high altitude fighter with a Jumo 213E engine (1,750 hp) and armament of three MK 108 30 mm cannon and two MG 151 15mm cannon, the later mounted on top of the engine in place of the machine guns. Never produced.

H-5 - Another proposed high altitude fighter, this time using the DB605L engine (1,700 hp), which had a two stage mechanical supercharger. Never produced.

J - Designation reserved for aircraft to be produced in Spain.

K-0 - The K series was very similar to the earlier G series, with only minor structural changes. The K-0 models were pre-production versions modified from G series airframes. The DB 605D engine was fitted. All the K series used the Erla cockpit canopy.

K-2 - First production version of the K series. Armament was an MK108 30mm hub cannon and two 15mm MG151 cannon on top of the engine. Engines used were the DB605ASCM and DB605ADCM.

K-4 -Same as the K-2 but with cabin pressurisation.

K-6 -Armament increased, hub cannon was MK 108 30mm and two additional MK 108 cannon were carried beneath the wings. Over the engine armament reverted to two 13mm machine guns.

Bf109K - last type to see combat

K-14  -Last production version Bf109 to enter service, the K-14 was powered by the two stage DB605L (1,700 hp) and carried an armament of a single 30mm hub cannon and two 13 mm machine guns.

L - Projected fighter using the Jumo 213E engine with a redesigned, broader, fuselage and modified wing. Never produced.

R - Fictitious designation of the Me 209 world speed record holder to make it appear that the Luftwaffe had fighter aircraft capable of 469 mph.

S - To improve handling at low speed for take-off and landing it was proposed to feed air from an intake under the fuselage to outlets at the flaps and ailerons, a system known as "blown flaps". Also did away with the wing radiators by using an evaporating cooling system. The S series was to have used these systems and work on the prototype (V24) was well advanced when the factory involved (in occupied France) was captured.

T-0 - The T series was to have been Germany's aircraft carrier fighter. (T stood for Traeger, German for carrier). The T-0 were modified E-3 aircraft.

T-1 - Full production version, built from the outset as carrier aircraft by the firm of Feiseler, the T-1 featured catapult spools, arrester hooks, and manually folded wings. The undercarriage was also strengthened to withstand carrier landings.

T-2 - When the order for the T-1 was cancelled the aircraft were stripped of carrier equipment and completed as fighter-bombers, with the strengthened undercarriage put to good use of supporting the weight of a bomb.

TL - Part of a large series of projects to combine the easily produced Bf109 with the new jet engine technology, the TL design featured a 109 fuselage with new wings mounting jet engines beneath them. Never built.

V - Designation given to all prototypes in the 109 series. Each of the major series would be proceeded by one or more prototypes that would have tested out the technical and structural advances. These prototypes would usually be all-new aircraft. Then pre-production airframes would have been built usually using airframes of the earlier models as a starting point ( i.e. E-0, F-0 and G-0). This would ensure the smooth introduction of each new series into production. See the section on early109 prototypes below.

Z - The Zwilling (twin) project was another attempt to make use of the easily produced 109 by combining two 109 fuselages and outer wings with a new wing section and tailplane joining the two halves together. This may seem strange but the American post-war F-82, which combined two Mustang fighter airframes in the same way, was outstandingly successful. The Zwilling would have been used as a heavy bomber destroyer or fast bomber. Only one pilot was needed, one of the cockpits being deleted.

Z-1 - Original design based on mating two 109F airframes. Armament of five 30mm cannon and 1,100 lbs of bombs. None produced.

Z-2 - Projected bomber version with only two 30mm cannon and a bombload of 4,400 lbs. None produced.

Z-3 - Same as the Z-1 but with Jumo 213 engines. One prototype was built, but it never flew.

Z-4 - Same as the Z-2 bomber but with Jumo 213 engines. Never produced.

HA 1110 K1L Two seat tandem trainer version with the 12Z-17 engine.

HA 1112 K1L When fitted with armament, the earlier 1109 became the 1112. Armament of two 20mm Hispano HS 404 cannon was fitted inside the wing, the first 109 type to do so since the 109E. For ground attack a total of eight 22lb rockets could be carried.

Rolls-Royce Merlin powered:-


The Buchon was the first type of "109" to carry internal wing armament since the E series.

The "Buchon" Spanish produced version of the 109, powered by a British Merlin engine. Note the chin radiator.

HA 1112 M1L Identical with the 1112 KIL except fitted with a Merlin 500-45 engine of 1,400hp driving a four bladed propeller. All the 1112 K1L aircraft were upgraded to the M1L standard.

V14 DB601 powered aircraft with armament of two machine guns and two wing cannon. This, together with the V15 was the prototype for the E series.

V15 DB601 engine, two machine guns and one hub cannon.


Bf 108 The forerunner of the Bf109, the 108 was a very advanced touring aircraft. Its wings were almost the same as the early 109 fighter's and it was an ideal two-seat trainer for the pilots of the Messerschmitt fighter. Production was continued in France after the war and its performance would shame many a small civil aircraft of today.

The dainty but tough Taifun tourer, used as a trainer and communications aircraft by the Luftwaffe.

Bf108 "Taifun"

Me 155 A Messerschmitt design for a completely new aircraft carrier fighter, the original Me 155 design had the nose contours and cockpit lines of the Bf109. The design was later developed into a high altitude fighter with a huge wingspan. Responsibility for the project was handed over to Blohm and Voss who changed the design somewhat and produced two examples, only one of which flew, but crashed. The Me 155 design was also involved in the planning of the Bf109TL project; it was hoped to use parts of the Me 155 in the TL to speed up production.

Me 209 High Speed design meant to produce the next generation of fighter aircraft for Germany after the Bf109. One of the prototypes gained the world speed record for Germany in 1939. When developed for combat use it  showed no significant advantage over the 109. Tested against the Focke-Wulf 190 and the Heinkel 100 (He 113), the Luftwaffe chose the Focke-Wulf as the successor to the Bf109. ( See also Bf109R.)

The Me 209 designation was also used for an entirely different aircraft, The Me 209-11 or V5 was based on the 109G aircraft. However the new design could well have been a "cover" to get a new improved fighter design past officials in the German Air Ministry who wanted production concentrated on existing proven types. With a wide, inward-retracting undercarriage and a DB603G engine of 1,900 horsepower the aircraft should have been a winner. Delays in production of the DB603G engine meant the aircraft had to be redesigned around a Jumo 213 engine. Prototypes were flown and all was set for production to start as the Me209A-2 when the project was ordered halted.

Me 262 Messerschmitt's twin jet engined fighter was years ahead of its time and was superior to any allied fighter. Had it been available earlier and in greater numbers it could have kept air supremacy for the Germans. At the same time the obvious promise of its performance stopped development of more advanced piston engined types by the German aircraft industry.

Me 309 An attempt to design a new fighter, the Me 309 project got as far as producing four prototypes, but the aircraft ran into many design difficulties and disasters. The initial tricycle undercarriage gave problems and the first prototype was damaged many times during take-off or landing. Five different tail designs were tried without success. In the end the project was cancelled and the existing prototypes used for testing of parts for the Me262.

Me 409 A design for a larger version of the Me309. Abandoned with the Me309.

Me 609 A development of the Bf109Z Zwilling aircraft. It never got beyond the design stage.
