G-3, G-4
In September 1942, the G-4 appeared; this version was identical to the G-2 in all respects, including performance, except for being fitted with the [Vous devez être inscrit et connecté pour voir ce lien] radio set, which provided much clearer radio transmissions and had
three-times the range of the earlier [Vous devez être inscrit et connecté pour voir ce lien] sets.
Externally this could be recognised by the position of the fuselage antenna lead-in which was moved further aft to between frames seven and eight on the fuselage spine.
Due to the steady weight increases of the 109, from the spring of 1943 larger 660 x 160 mm (26 x 6.3 in) mainwheels were introduced, replacing the previously used 650 x 150 mm (25.6 x 6 in) type.
The undercarriage legs were altered so that the wheel's vertical axis was nearly upright rather than being parallel with the [Vous devez être inscrit et connecté pour voir ce lien] leg.
These changes resulted in the fitting of teardrop-shaped fairings to the upper wing surface above the wheel-wells to accommodate the upper part of the mainwheels.
The larger wheels and fairings were often retrofitted to G-2s.
In addition, a larger 350 x 135 mm (14 x 5 in) tailwheel replaced the original 290 x 110 mm (11 x 4 in) one; the larger tailwheel no longer fitted the recess, so the retraction mechanism was disconnected and the tailwheel fixed down.

Up to July 1943, 1,242 G-4s were produced, with an additional four in Győr and WNF factories in the second half of 1943.
Between January and February 1943, 50 examples of a pressurized version, the G-3 were also produced; similar to the G-1 although it was equipped with the same FuG 16 VHF radio set as the G-4.
The following variants of the G-3 and G-4 were produced:

The G-6/U4 variant was armed with a 30 mm (1.18 in) MK 108 cannon mounted as a Motorkanone firing through the
propeller hub instead of the 20 mm MG 151/20.
The G-6 was very often seen during 1943 fitted with assembly sets, used to carry bombs or a drop tank, for use as
a night fighter, or to increase firepower by adding rockets or extra gondola guns.

One offensive weapons upgrade in 1943 for the Bf 109G was one that mounted the Army`s [Vous devez être inscrit et connecté pour voir ce lien] rocket weapon system with one launching tube under each wing panel.
The rockets, fitted with a massive 40,8 kg (90 lbs) warhead, were aimed via the standard Revi reflector sights, and were
spin-stabilized in flight.
In emergency, the tubes could be jettisoned via a small explosive charge.
Intended as a "stand-off" weapon, fired from a distance of 1,200 meters and outside the effective range of the formations defensive guns, it was employed against Allied bomber formations, the Wfr. Gr. 21 rocket was unofficially known as the BR 21 (Bordrakete 21 cm) for the Bf 109G-5, G-6 and G-14.
The weapons system received the designation of Rüstsatz VII on the G-10.

Late-production G-6, G-14, G-14/AS
Some versions of the G-6 and later Gs had a taller tail unit and redesigned rudder which improved stability at high speeds.
The introduction of the WGr. 21 cm (8 in) under-wing mortar/rockets and the 30 mm (1.18 in) MK 108 cannon increased firepower.
Certain production batches of the Bf 109G were fitted with [Vous devez être inscrit et connecté pour voir ce lien] to decrease stick forces at high speeds.
A radio-navigational method, the Y-Verführung (Y-Guidance) was introduced with the FuG 16ZY.
Subsequent Bf 109G versions were essentially modified versions of the basic G-6 airframe.
Early in 1944, new engines with larger superchargers for improved high-altitude performance (DB 605AS),
or with MW-50 [Vous devez être inscrit et connecté pour voir ce lien] for improved low/medium-altitude performance (DB 605AM),
or these two features combined (DB 605ASM) were introduced into the Bf 109 G-6.
Maximum speed of the G-5/G-6 was 530 km/h (320 mph) at sea level, 640 km/h (391 mph) at 6,600 m
(21,650 ft)-rated altitude at 1.42 atm boost.

The G-14 arrived in July 1944 at the invasion front over France.
It represented an attempt to create a standard type, incorporating many changes which had been introduced during
production of the G-6, and which led to a plethora of variants, plaguing decentralized mass production.
The standardization attempt proved to be a failure, but overall the type offered improved combat performance, as [Vous devez être inscrit et connecté pour voir ce lien] power boosting [Vous devez être inscrit et connecté pour voir ce lien] (increasing output to 1,800 PS (1,775 hp, 1,324 kW), the clear-view Erla Haube was now standard installation.
Top speed was 568 km/h (353 mph) at sea level, and 665 km/h (413 mph) at 5 km (16,400 ft) altitude.
A high-altitude fighter, designated G-14/AS was also produced with the DB 605ASM high-altitude engine.
The ASM engine was built with a larger capacity supercharger, and had a higher rated altitude, and correspondingly the top speed of the G-14/AS was 560 km/h (348 mph) at sea level, and 680 km/h (422 mph) at 5 km (16,400 ft) altitude.

There was increasing tendency to use plywood on some less vital parts e.g. on a taller tailfin/rudder unit, pilot seat or instrument panel. A caution estimate based on the available records suggest that about 5,500 G-14s and G-14/AS were built.
The following variants of the G-14 were produced:

G-10
W Referred to as the "bastard aircraft of the Erla factory" in the Luftwaffe's Aircraft Variants Book of December 1944, the G-10 was a Bf 109 G airframe combined with the new DB 605 D-2 engine, created to maintain production levels with minimal disruption of the assembly lines until production of K-series airframes would reach sufficient levels.
Despite what the designation would suggest, it appeared in service after the G-14 in November 1944, largely replacing previous G-series aircraft on the production lines of Erla, WNF and Messerschmitt Regensburg factories.
Evidence suggests that G-10s were rebuilt from older airframes, supplementing production of the new K-4s with aircraft of almost equal value in the cheapest possible manner.
One apparent indication was two aircraft identification plates on the port forward fuselage, below the windscreen rather than one

The most recognizable external change was the use of the "Erla-Haube" clear-view canopy.
Internal changes included inheriting the new 2,000 W generator and the DB 605 D-2 engine of the 109K.
Apart from the standardised streamlined engine cowlings, G-10s with the DB605 D-2 were equipped as standard with the MW-50 booster system (DB 605DM) and had a larger Fo 987 oil cooler housed in a deeper fairing.
Also, because of the engine's enlarged crankcase and the oil return lines which ran in front of it, these G-10s had small blister fairings incorporated into the lower engine cowlings, forward of and below the exhaust stacks.

Miscellaneous variants: G-8, G-12
The G-8 was a dedicated reconnaissance version based on the G-6.
The G-8 often had only the Motorkanone engine cannon or the cowling machine guns installed, and there were several
subversions for short- or long-range reconnaissance missions with a wide variety of cameras and radios available for use.
The Bf 109 G-12 was a two-seat trainer version of the Bf 109.
This was a conversion of "war-weary" or rebuilt G-4 and G-6 airframes;
the space needed for the second cockpit was gained by reducing the internal fuel capacity to only 240 L (60 US gal)
meaning that the 300 L (80 US gal) drop tank was employed as standard equipment.
This version was rarely armed with anything more than one or two cowling machine guns.
The rear cockpit canopy was bowed out to give the instructor, who sat behind the student pilot in an armoured seat, a clearer view.
The rear cockpit was also equipped with a basic instrument panel and all flight controls.

Bf 109G subtypes and variants
The base subtypes could be equipped with Rüstsatz add-on standard field kits; in practice this meant hanging on some sort of additional equipment like droptanks, bombs or cannons to standard attachment points, present on all production aircraft.
Aircraft could be modified in the factory with Umrüst-bausatz (Umbau) conversion kits or by adding extra equipment, designated as Rüstzustand, to convert standard airframes for special roles – a reconnaissance- or bad-weather fighter, for example. Unlike the Rüstsatz field-kits, these modifications were permanent.
The Rüstsatz kits were designated by the letter "R" and a Roman numeral.
Rüstsatz kits did not alter the aircraft's designation, so a Bf 109 G-6 with Rüstsatz II (50 kg/110 lb bombs) remained designated as 'Bf 109 G-6', and not 'G-6/R2' – the G-6/R2 was a reconnaissance fighter with MW 50, as suggested by
most publications.
The Umrüst-Bausatz, Umbau, or Rüstzustand were identified with either an "/R" or "/U" suffix and an Arabic number, e.g. Bf 109 G-10/U4.
