Bf 109D (Dora)

The V11, V12, V13 were originally the last 3 Bf 109B-0 airframes.  There
were less than 200 Bf 109Ds produced.

Modelling Comments: The 'Ds were identical to the C aft of the firewall
(with the exception of a castoring tailwheel), and had a cowling nearly
identical to the later 'E, having a semi-flush tubular extension forward of
the supercharger intake, and 'C-style exhaust stacks.

     Engine:   DB 600Aa
     Armament: 2 MG 17 in cowl, 1 MG FF/M (some were
               removed, with an increase in MG 17 ammuntion
               to 1000 rounds)
     Propeller:     2-bladed controllable-pitch
     Spinner:  Cropped
     Notes:    3 gun-cooling slots in engine cowling

------------------------------------------------------------------------
Bf 109E (Emil)

Modelling comments: The first 3 prototypes (V13, V14, V15) were assigned
the first 3 pre-production codes (Bf 109E-01, -02, -03).  The 'E retained
the small, short spinner of the 'C and 'D, but replaced the 2-speed
prop. with a 3- speed constant speed unit. The Emil retained the small,
cropped spinner used in the 109D.

Bf 109F (Friedrich)

Modelling comments: The 'F incorporated sevral structural changes that
would remain, largely unchanged, throughout the rest of the series.  These
include:
     *  Underwing radiators were made shallower and recessed
        more into the wing.
     * Split flap behind radiator, the lowe part of which
       changed position thermostatically.
     * Change in length and span of leading- and trailing-edge
       flaps & elimination of interlinkage between flaps &
       ailerons.
     * Addition of detachable, semi-eliptical wingtips.
     * Deeper, more streamlined cowl which tapered directly
       from windscreen to spinner.
     * Enlarged & lengthened spinner.
     * Airscrew diameter reduced by 10 cm, but blades wider.
     * Tailplane struts were eliminated, and tailplane moved
       slightly Forward and down, and the chord thickness
       increased.
     * Deepened oil cooler bath below engine.

Bf 109G (Gustav)

Modelling comments: The 'G incorporated the following changes from the 'F:
     * Larger tailwheel (non-retractable, tailwheel well
       faired over)
     * Larger main wheels with different tread pattern, with
       bulged fairing in wing top to accomodate larger main wheels
       (G3 onwards except G4)
     * Slightly larger supercharger intake scoop.
     * Later 'Gs incorporated cowl bulges.
     * Canopy side windows have vertical brace in middle of
       panel, and the elimination of the lower quarter-lights
       (i.e., the small triangular windows below the windscreen).
       This is in aid of cabin pressurization.
     * Pilot's head armour is bulkier, and more "wrap-around".
       This is in aid of cabin pressurization.
     * Addition of a pair of small scoops behind propellor hub
       on both sides of fuselage for engine direct cooling.
     * Late 'G-5 was the first to incorporate "Galland"
       canopy, which wasn't standard until the G-14.
     * Upper cowling is recontoured to provide a virtually
       unbroken curve from spinner to fwd. decking.
     * Upper cowling on 'G5 and later incorporated bulges for
       the breech of the Mg 131 machine guns.
     * Enlarged oil cooler

guns.  Those a/c equipped with the DB 605AS have "AS" appended to the type
designation (e.g., Bf 109G-5/R3AS).  GM 1 nitrous oxid injection gave way
to dual-stage supercharging.

Bf 109Z

The Bf 109Z (Zwilling =3D siamese twin) was a Messerschmitt proposal to
produce a high-performance fighter by mating a pair of Bf 109F fuselages at
the wing and tail with a straight centre section. The starboard cockpit was
faired over, and each half's undercarriage was moved to the fuselage
centreline, yielding a peculiar 4-wheel undercarriage.  The centre section
could carry over 500 kg, and each outer wing was equipped with a hardpoint
for an SC 250 bomb

Bf 109 Experimentals and One-offs

?????????:
Bf 109E-4 fitted with a fully-feathering airscrew & a towline attachment in
the spinner (where the cannon would normally fire through).  Test tows were
performed with a Bf 110.  Both aircraft would take off under power, and the
109 would shut down its engine once airborne.  Tests were successful, but
the design was not adopted.

?????????:
Bf 109E-8 fitted with non-retractable skis resembling flat- bottomed
pontoons, wheel wells crudely faired over (unpainted).  Tested with skis
alone and with jettisonable 3- wheeled dolly, the project was never put to
use because operations with conventional configurations proved that the
skis were unnecessary.

?????????:
Bf 109E-4 tested with 300 l overwing slipper fuel tanks in 1942. Eventually
dropped in favour of the centreline ventral drop tank, the idea was revived
in 1943 as an over-wing container carrying a man, parachute and survival
equipment for covert operations or for casualty evacuation.  Tests were
later continued with a Bf 109G-12.  While successful as both tankage and
personel carriers, the ideas were never incorporated operationally.

???????:
Bf 109F-1 adapted to use the BMW 801 radial engine (it appears to be a FW
190A from the firewall forward).  Severe turbulence around the tail forced
abandoment of the tests.

???????:
Bf 109F-1 adapted to use the Jumo 213 engine with annular radiator (it
appears to be a FW 190D from the firewall forward).

???????:
Bf 109F-2 (Werk-Nr. 9246) tested with four E.G., 65 launchers for 73mm
Rheinmetall-Borsig RZ 65 rockets.  Intended as a bomber destroyer and
ground attack. Abandoned due to complexity and high drag.

???????:
Bf 109F-4 (Werk-Nr. 14003 VJ+WC) tested with a butterfly (i.e., 'V')
tail.  Initial flight tests Jan 21, 1943.  No substantial improvements in
performance, and some degradation of stability led to its
abandonment. (Modelling note: tailwheel is non-retractable & opening is
faired over.)

Bf 109 V30a    Werk-Nr. 5717
Bf 109F-1 tested the Me 309 cabin pressurization and air-conditioning
systems. (See the Bf 109F section for details.)

Bf 109 V31     Werk-Nr. 5642
Bf 109F-1 modified with a broad-track undercarriage that retracted inwards,
and a semi-retractable radiator bath.  Used as a test vehicle for the Me
309 programme. (See the Bf 109F section for details.)

Bf 109G-1/U1
A Bf 109G-1 was fitted with a Messerschmitt P-6 reversible propeller for
short field landings.

Bf 109G-2/R1 (BD+GC)
A long-range fighter-bomber adaptation by Fieseler, who adapted a 'G0 to
'G2 specs. by re-engining it with a DB605A) to accept an SC 500 bomb on a
centerline rack, and 2 300 l drop tanks on wing hardpoints just inboard of
the leading- edge slots. To provide clearance for the SC 500, a long,
jettisonable oleo leg was added behind the cockpit.
     Engine:   DB 605A-1 or DB 605B-1

Bf 109G-2/??
A photo-reconnaissance 'G2 was modified with a WT 17 (Waffentropfen =3D
Weapon Drop) unit comprising a pod with a pair of aft-facing MG 17 machine
guns c/w ammunition.  This pod would replace the normal vertical camera
mount.  Weight and drag penalties prevented it from seeing service.
