Minor changes.And so it begins...
BTW, there are no mayor changes to the Luftwaffe tactics against warships in this ATL, right?
As mentioned in 5., which deals with the Kanalkampf, there's the Bf 110. In this ATL, its heavy fighter role is secondary, while it's much more used for ground attack (the reverse of OTL); it follows it is also used against minor shipping. There are two problems, however:
- during the Kanalkampf, the targets were slow, unarmed, unprotected small cargo ships. Attacking fast, armed, armored warships is another kettle of… ships. Though the Bf 110 would still come in handy against the minor auxiliary boats in Royal Navy service.
- but what's worse, during the Kanalkampf the Germans still had a sizable number of Bf 110s. Using them intensively against ground targets which are getting better and better AA defenses took its toll. When the time for the invasion came, the remaining Bf 110s had to be mostly used for other tasks than against ships.
Note that in both cases (attacking cargos during the Kanalkampf or patrol boats during the invasion) it's not important that the Bf 110's weaponry might not sink the targets. Damaging them heavily would serve the real purpose of both attacks just as well.
The other change is not doctrinal. Wever has seen the need for more AP bombs for the Stukas, and has tried to have more of those stocked – though with not entirely satisfactory results.
I do not deem that there are any other changes that could reasonably be implemented. As a rule, I stuck to minor, very simple, realistic and reasonable changes.
