located under the fuselage under the wing center
section or under the left wing.

mounts on the left side of the fuselage below the
cockpit.
• Bf 109 G-6/U4/trop from production blocks 440 000
through 442 000 (up to 442 099) produced by WNF had
a cover on the right side of the fuselage between
the 4th and 5th fuselage bulkheads to access
the compressed air cylinder for the MK 108 gun.
• Bf 109 G-6/U2s from production blocks 410 000 to 412
000 (105 units) and 413 000 (240 units) from Erla had
a GM-1 cylinder access cover on the right side of the
fuselage spine in front of the third fuselage bulkhead.
• A REVI 16 B gunsight from the summer of 1944. Applies
to production blocks 413 000 (Erla) and 440 000 to 442
000 (WNF).
• Production blocks 410 000 to 413 000 (Erla) machines
had a bump on the right fairing covering the breech of
the MG 131 machine gun.
Example: Bf 109G-6/R6, W. Nr. 412951 (Erla Production),
flown by Lt. Horst Prenzel, 1./JG 301, Gardelegen, Germany, July 1944
Fifth Production Variation:
163 000 to 167 000 (Messerschmitt)
The equipment of these airframes correspond-
ed to those of the fourth production variant. They
are characterized as follows:
• Erlahaube canopy (18).
• Small rudder.
• Wing/fuselage interface could be of wood.
• Short antenna mast
• They were alternatively equipped with a FuG 16 Z or
FuG 16 ZY radio with an on-board transponder for the
Pegasus Y targeting system with a Morane-type whip
antenna (Moranmast) located under the left wing (19).
• Guidance system consisting of a ZVG 16 unit with its PR
16 (Peilrahmen) loop antenna on the top of the fuselage.
• Identification Friend or Foe (IFF) FuG 25a system with
a rod antenna under the fuselage behind the 2nd
fuselage bulkhead.
• A small fuel tank for starting the engine, with a filler
neck on the right side at the top of the fuselage
between fuselage bulkheads 4 and 5.
• A REVI 16 B gunsight from the summer of 1944. A part
of production block 163 000 still had the REVI C 12 D
sight installed.
• Production blocks 165 000 to 167 000 (Messerschmittt)
airframes had a bump on the right fairing covering the
breech of the MG 131 machine gun.
Example: Bf 109G-6, MT-477 (Messerschmitt production), HLeLv 31, Utti, Finland, Summer, 1948
Sixth Production Variation:
Production blocks 164 000 to 167 000 (Messer-
schmittt) and 413 000 (Erla).
These airframes displayed the following char-
acteristics:
• Tall tail.
• Erlahaube canopy.
• Some sections of the airframe were made of wood (tail
surfaces and wing/fuselage interface)
• Small fuel tank for use in engine starting with a filler
neck on the right side of the fuselage spine between
bulkheads 4 and 5.
• Most were equipped with a FuG 16 ZY radio with an its
associated transponder for the Pegasus Y goniometric
targeting system with a Morane-type whip antenna
(Moranmast) located under the left wing.
• Short antenna mast.
• ZVG 16 guidance system with its associated PR 16
(Peilrahmen) loop antenna on the top of the fuselage.
• Identification Friend or Foe (IFF) FuG 25a with a rod
antenna under the fuselage behind the 2nd fuselage
bulkhead.
• Some of the 167 000 production block airframes had
a longer tailwheel strut without a cover sleeve (29).
• Production blocks 165 000 to 167 000 (Messerschmitt)
and 413,000 (Erla) aircraft had a bump on the right
fairing covering the breech of the MG 131 machine gun.
• A REVI 16B gunsight was fitted.
Example: Bf 109 G-6/R6, W.Nr. 165350 (supplied by Messerschmitt), flown by
Lt. Anton Hafner, Commanding Officer of 8./JG 51, Tilsit-Ost, August 1944
Bf 109 G-6 Subtypes
Factory Level Conversion Equipment
and Weapons Sets / Umrüstsätze U2
and U4
Bf 109 G-6/U2: a total of 345 aircraft, produced
by Erla A.G. Leipzig, were equipped with a GM-1
(injecting nitrous oxide into the cylinders) system
providing a short-term increase in engine power.
The nitrous oxide pressure bottles were located
in the fuselage, the access hatch to them was in
the upper part on the right side of the fuselage
between the second and third fuselage bulk-
heads (20). The first 105 aircraft were built in the
410 000 to 412 000 production blocks between
October, 1943 and June, 1944. A further 240 units
were built in the 413 000 (more precisely 413 300
A significant number of this production varia-
tion were delivered to the Hungarian and Finnish
air forces.
