Think functional dislocation which means combined arms deprive the enemy of one of it's combined arms branchs.If Axis player wants to commit sizable assets to Atlantic there's little to be done except minimizing losses until US/USSR join. Convoy hunting alone won't win the war though, delaying Barbarossa until '42 and taking Britain and/or Med/Iraq is probably a better alternative.
I usually cap at 6 subs (in 2 groups) when aiming for '41 Barbarossa and unless all 6 are used together they're not overwhelming. 3 subs might take down a 10step low tech DD but that takes luck. As long as Allied player keeps the fleet tight (i.e. single ship can only be attacked from 1 direction without retaliation) it will be too costly. E.g With 6 DDs a single convoy can be escorted without huge risk unless Axis BBs are lurking around and those can be countered with RN BBs/CVs.
The counter to an allied dd is an axis bb.
The counter to an allied cv or bb is an axis sub.
The counter to an allied sub is an axis dd.
The counter to an allied strat is an axis cv.
Think positional dislocation. The amibrits naval units have to disperse whereas the germans can concentrate at will.
In operational terms the sea is a highway providing operational mobility for the western allies.
In Clausewitzian terms the amibrits naval units are the center of gravity that allows them to accomplish their objectives.
How many pps should the germans spend on building naval units for the possibility of naval supremacy and what should they spend them on? I don't think spending 180 pp's for 3 german subs is enough.
I'd guess the germans should spend 500 pp's considering they start with 1 dd, 1 bb and 3 subs and 1 more bb in the build queue.
