Some Thoughts...All over the place...
Oct 1942 German medium tank production Mark IV's was 100 per month.
Russia in Oct 1942 was producing a mix of T-34's and KV's heavys at 2000 a month
------------------------------------------------------------------------------
That month Hitler ordered production increased to 600 per month... Mark IV's
{Germany may have had vehicle assembly line tech but sure as H wasn't using it!}
Russia had two darn fine tank designs and unlike Germany she didn't allow herself to be distracted by new toys. T-34's... she pumped em out like crazy.
-------------------------------------------------------------------------------
There also was a war raging in German power circles over tanks verus self propelled guns and much of the tank chassis production went to SPG's instead of the more useful tanks.
The main problem was a hopelessly unorganised production plan.
{blame DR. Fritz Todt} and in fighting between OKH and the SS.
Many firms were offering competing designs and everything was being tested and retested (two versions of Panthers and two versions of Tigers) but nothing was decided and nothing was getting built .
In Feb 1943 the OKH stepped in with an appeal to Hitler and Guderian was appointed to straighten out the mess.
And at the same time Todt died in a plane crash. Speer was appointed as Armaments Minister.
Production for total war still ....really did not really get organized until after Sept 1943.
----------------------------------------------------------------------------------
My point...tech wasn't the problem...German had the tech... "people" was the problem and only a EVENT provided the solution.
---------------------------------------------------------------------------------
When I read about people being upset with Allied non historical abilities to build armies in peacetime I ponder that Germany lacked the abiltity after 3 years of war!
Perhaps they should read up on what USA had in the production cue DURING peacetime. Most of her carriers and battleships were building in the peacetime shipyards long prior to Pearl Harbour.
She also had bomber and fighter designs ready to be mass produced and readied her product lines to be able to.
All during peacetime.
{just add water and stir}
---------------------------------------------------------------------------------
After thought ...people remained the problem - Germany produced 0ver 7,000 planes (5,000 fighters,1100 tac, 1000 jet fighters) in the last two months of the war Jan/Feb.
An over all production increase of 350% over 1944...But had no pilots trained or left to train , nor fuel.
I sumise the production situation on tanks and subs was similar but lack the data sources to verify this.
