Bf 109 G-6 A/S

Post by Kris79 » 07 Dec 2006 22:09

Hi there,can somebody tell me the main differences between the ´standart´ 109 G6 and the G-6 A/S expecially in the engine,what´ the tecnical difference-----maximum power----topspeed----climbing rates...
And has the A/S the same turning perfomance or is it better?

heres a G6,am i right the A/S has not the typical bubbles for the 13mm guns?
I´ve only read obout it...

In IL-2 Sturmovik (PC game), the Bf 109G-6 AS looks exactly like the G-10 exept for G-6 wings. Ithink that Bf-109s with the AS ending had a 50 MW mentol(something) injection which could boosts it power for ca. 2 minutes every 10 minutes.

The /AS designates the that the DB605 powering that aircraft (in this case a G-6) was fitted with the larger supercharger of the DB603. This provided better power at altitude and increased the full throttle height of the standard DDB605. The cowling need to be re-designed to accommodate the large supercharger thus a G-6/AS wouldn't have the tell tale 'bulges' of a standard G-6. MW-50 has nothing to do with the AS designation. Typical a DB605 + DB603 w/ MW-50 supercharger would have been designated as a Bf 109G-14/AS.

The Bf 109G-6/AS entered service with JG 1, JG 5 and JG 11 in late spring 1944 (April / May) but in limited numbers.

Quick addition to what the others already said:

Indeed the designation G-6/AS is for DB-605 AS equipped Bf 109G-6. This engine had a larger supercharger, and consequently better high altitude performance, performance up-high was similar with that of Bf 109G-10 (but not so at low altitudes). It appeared in late spring 1944, especially on Western Front, to counter the new Allied types with updated high altitude performance.

What you are probably interested in is the overboosted Bf 109G-6/U2. This is the designation for the plane fitted with DB-605 AM, that used MW-50 injection. It appeared in late spring 1944 too, and should not be mistaken for the Bf 109G-6/U2 made in 1943, which was a regular G-6 with a wooden tail. It was used mostly on Eastern Front, when in late spring 1944, the Soviets introduced new fighters that could challenge Bf 109 in climb rate and acceleration at low altitudes.

Bf 109G-6/U2 outperformed Bf 109G-6/AS at low altitudes. At high altitude the situation was reversed. Bf 109G-6/U2 was introduced initially as field modifications, only latter they came as such from the factory. There was also a version called Bf 109G-6/U2/AS :D that used DB-605 ASM, which had both the MW-50 boost system and the larger supercharger. Not many were produced to this standard as they were soon replaced by Bf-109G-14/AS and Bf 109G-10 (Bf 109G-6/U2 was replaced with Bf 109G-14, but not all G-14 left the factory with the MW-50 system installed).

DB-605 AS, AM and ASM were adopted because DB-605 DB and DC were not ready yet for service in spring 1944. AM and ASM were somewhat troublesome engines, because they were not designed to operate at these high boost levels. They were replaced with DB-605 ASB and ASC, which adopted most modifications made for DB-605 DB and DC (B versions used the lower octane fuel B-4, C versions used higher octane C-3 fuel). DB-605 ASB and ASC were kept in production in parallel with DB and DC versions, in order to increase production. All late Bf 109 that used the bigger supercharger had the modified cowling (AS, ASM, ASB, ASC, DB, DC), only the 109s that used the early A or AM DB-605 had the old G-6 cowling.

I./JG 3 Bf 109G-6AS were all equipped with MW 50 injection as noted by vets flying the crate in April 44 to Normandies beginnings as well into that ugly campaign

Moskito-Jagern of 10. N. JG 300 flew the bird with MW 50 as well as gruppen of NJG 11 chasing Mossies and 4 engine jobs.

JG 27 were to receive theirs a bit later as portions of I and III./JG 300 combating P-51's at over 25,000 ft to 30,000 feet

The /AS conversions included some more modifications, many of the G-5/AS and G-6/AS received the Erla-Haube, all should have the wooden tail with larger rudder. AFAIK they also used a different prop with wider blades (for better altitude perfromance) but I'm not that sure about this.

A G-6/U2 is equipped with GM-1, it looks the designation was also used for the 1944 MW-50 kit applied to G-6. They probably used a similar installation except for a different fuel tank .

The cowling need to be re-designed to accommodate the large supercharger thus a G-6/AS wouldn't have the tell tale 'bulges' of a standard G-6.
But did twin 13 mm MG 131 armament changes in G-6/AS variant, yes or not ?
The question has not been answered, certainly Bf 109 G-6 A/S is not a "Beule".

The enlarged cowling was spacious enough to fit the MG 131 without need for Beulen
