Re: Bf 109 vs. Spitfire production costs

1. During preparing the licence production agreementin Győr, Hungary, Generalluftzeugmeister has sent a 18 page letter titled Bf 109 in Lizenz für Ungarischen Waggonwerke Győr, detailing the very intricate details (labour, factory space, raw materials need) for series licence production of 109F, production assumed at a rate of 10 aircraft per month. The figures have been produced by László WINKLER some ten years ago in the automn 1997 Haditechnika magazine.

109F
Proto series: 18 000 hours
From 100. aircraft. 7 200 work hours
From 200. aircraft: 6 000 work hours

2. To quote George's earlier post in this board from the thread 'Compare of Bf 109 and Fw 190 cost of production':

According to an Mtt report of 11.5.44, the manhour cost in hours, "Femi-Kosten in Stunden" is how they state it, for the 109G is as follows: For 50 a/c produced per month - 460,000 hours (9200 hrs/per); for 200 a/c per month - 1,300,000 hours (6500 hrs/per); and for 500 a/c per month - 1,900,000 hours (3800 hrs/per). I did the division to get the time used per a/c, so you might check it. The production was broken down into four assemblies: fuselage, control surfaces, wings, power plant; with times for each assembly.

This report was to breakdown the assembly time for the various components of the Me 262, so gives only the above breakdown for the 109.


3.
From another source showing actual production hours needed for large scale series production in Germany, by 1944 construction time went down from IIRC 9000 hours for the 109E to 6000 hours per airframe on the 109F, and to something like 2300 hours per 109G airframe by 1944. Cannot find the comparison but iirc it compared the learning curves and decreasing man hour costs for the 109, 190, 88 across the war. I will try to find it amongst my files and post it..
