View Full Version : 109G-6\AS Info

Was reading some 109 book I own and it says that only a Few G-6\AS were produced in relation to standard G-6 models.

The G-6\AS was used by one squadron in each group as a high altitude fighter since the DB-605\AS did better at altitude than regular 605.

So the G-6\AS would fight the escorts while the 190's and 109's with rockets and gun pods would attack the bomber formations.

Just thought I would help put the G-6\AS into perspective since there are so many variants of 109 that saw service. I know it can get a bit confusing as to what why and where to the casual observer.

Probably an old book - the first /AS prototypes were produced towards the end of 1943. It was then when the more simple DB 605AS (a DB 605A with the big supercharger of the DB 603, hence the 'S' desigation for Sonder or special) was chosen over the two stage, four speed DB 628. The 605AS had much better altitude performance, and a rated altitude of about 8 km as opposed to 5.8km of the DB 605A; at low altitudes the AS produced around 40 less horsepower, but with MW 50 it (DB 605ASM) was similiar to the DB 605AM.

A total of 686 of G-6/AS was produced, plus around a hundred or so pressurized G-5/AS. So in a sense it was not a major production model, but this is a bit misleading since essentially the same type was produced afterwards under the designation of G-14/AS, of which well over a thousend was built. In late 1944 they were largely replaced by the G-10 and K-4 on the production line.

Probably the first unit that got them was Heinz Knoke's JG 11 on the Western Front, at around the end of March/early April 1944. These ones also had MW 50 boost, but it seems not all G-6/AS got them (as opposed the G-14/AS on which it was standard).

109 was heck of a plane...
