It also impact the
AGNA - and this was important to Germany as it was effectively tacit agreement from Britain to rearm and build a 'balanced fleet' 30% that of the UK with an initial 40% ratio of U-boats to British Submarines (about 40 odd British ones) and later on a 100% - so in 1939 they had about 50 odd
The rule of thumb is to have a U boat in the Atlantic you had to have another working up to a patrol and another in refit / training
So in order to have sufficient numbers of U boats required to successfully blockade the UK they need hundreds of them in 1939/40
But the problem with that is it would take Germany some years to build up the infrastructure, industry and train the crews for such a fleet which would be noticed.
This would result in no AGNA and no UK thinking Hitler was someone with whom they could deal with during the late 30s resulting in a harder line from Britain and a much earlier proper rearmament
