Starting a 1938 tech on January 1st, 1937 is extreme tech rushing because achieving doctrines is far harder than most other techs. Most doctrine techs are actually started near the end of historic year, not beginning of previous year.
Starting a tech a year ahead of time to have it achieved in time of its historic year is a regular thing for germany to do. This is normal techrushing, that is nothing extreme. Tech rushing does not depend on the difficulty of a tech.
Your whole research schedule is very optimistically advanced and conflicts seriously with all the other really good advice you ever wrote about not overly tech rushing - in fact your recommendation that Germany ONLY USE A FEW TECH SLOTS IN 1936, correct? Now you switch it to win a point? Anyway, your schedule is off by a couple years if player does actual game instead of theoretical possibilities.
No switch. I retain that using few slots in early 1936 is wise. This slowly changes as available ic increases the amount of tech slots that can be funded, reaching 9 slots before the end of 1936.
The figures are there to demonstrate that germany has doctrines equal or better than what any other nation will have at that time. However the concrete schedule is not sensible. There is no need have naval doctrines one year before they will be used. Also it might be convenient to use skill 7 Reader instead of a skill 9 team without matching expertise, this will save some bucks at the expense of being about 40 slot days less advanced. Here is a more reasonable schedule:
1938 Base Strike Doctrine takes 389 days till 1938/1/30 with Reader at +10% research.
1939 Indirect Approach Doctrine, copy takes 365 days till 1939/2/5 with Reader at +15% research.
1939 Subsidiary Carrier Role Doctrine takes 320 days till 1939/12/25 with Reader at +20% research.
1939 Carrier Task Force Doctrine takes 258 days till 1940/9/13 with Reader at +20% research.
1940 Indirect Strike Doctrine takes 248 days till 1941/5/21 with Reader at +20% research.
1940 Deep Operations Doctrine takes 186 days till 1941/11/27 with von Manstein at +20% research.
This will still be too early, so starting Base strike later in 1937 might be sensible.
Anyway, your schedule is off by a couple years if player does actual game instead of theoretical possibilities.
The possibilties are there, but one does need to have the will to use them. I prefer to skip all techs that i consider unessential for my grand campaign. If one want to research many different unit types, than the reasoning changes in favour of staying at Sealane Interdiction Doctrine. That would save a great aoumot of slot days, thus more slots days will remain for more division types.
Another fact possibly relevant for your reasoning is that since version 1.09 past historical date the historical date modifier is changed by 0.001 each day till to the maximum 2. In 1.08 it only was 0.0005 till to the maximum of 1.5.
Only if you have no imagination to exploit amphibious possibilities in hastening the defeat of the Red Army.
I have no desire to hasten things. I want to wage war in an efficient and elegant manner. This means not to start the german soviet war before Arm1943. The speed 15 combined with +10% speed from ministers allow an elegant annexation of soviet union with low losses due to attrition.
So you call 18 CVs a "small navy".
Do i? I stated that having a larger navy makes no sense, that would contradict the notion of a small navy.
No AI country ever has 18 CVs
I have seen that happening. Both Japan AI and USA AI might reach that level if production is not compensated by the timely sinking of carriers. It might have been different before 1.09.
But you want 18 for 1 ocean. I imagine that will be two CTFs of 9 CVs each.
Possibly. But also 3 CTF of 6 CV each can make sense to utilize Reader and two vice admirals. Whatever suits circumstances is wise.
When doctrines are as lopsided as occurs when Germany switches to Base Strike with the USA starting out 8 naval doctrines ahead, but Germany looks for conflict on the high seas in 1942, you will discover that a properly build USA CTF of only 3 CVs but having BBs or CAs will nearly instantly sink Germany's 9 CVs. Expect your positioning to be about 40 versus 100 for USA.
The facts suggest otherwise. First of the USA only start 3 techs ahead in naval doctrine. It is unreasonable to assume that by mid 1942 they will be more advanced than a human germany. They might even be behind in tech, but for sake of simplicity i assume that both have 1940 Deep Operations Doctrine and 1939 Hunter-Killer Group Doctrine. This means
32.5 to 75 positioning for CV
35 to 75 positioning for DD
32.5 to 75 positioning for CL
32.5 to 75 positioning for CA
30 to 70 positioning for BC
30 to 70 positioning for BB
Anything but DD and CV will decrease positioning and likely will decrease speed below 30. Anyway, i expect AI to do better than to use only 3 CV against a proper CTF of say 12 CV in two fleets of 6 CV each. With a third fleet of that kind being in reserve close by. But then again making AI expose its fleets in the open sea for naval bombardement is the key for an efficient naval warfare.
The CAG brigades need 188 days to construct (includes retooling). So you need to achieve CV-1943 (CAG-1943) tech at:
June 3/42 minus 188 days = Nov 25/41.
Construction takes 141 days. Retooling takes up to 40 days and only half of it needs to be done before achieving the needed tech. Still this would be 1941/12/22.
But as you have huge penalty for extraordinary extremely advanced research, you actually need to start research for the CAGs about mid 1940 to get CV-1943 (CAG-1943 Heavy Advanced) achieved in time to so build the CAGs separately by the time the CV-1941 Advanced (CV-5) are constructed. The whole plan is unrealistic, extreme, and will never occur because at same time there is much competition for other research. NOBODY starts 1943 tech in 1940.
I do, but only for Arm1943. Building CAG1943 is not really a good idea. Building CAG1941 and upgrading afterwards is a much more economical use of research slot days. Still having CAG1943 in mid 1942 is sensible and june is doable, for USA it even is reasonable. But for what i had in mind for germany it is not suitable. In the 120 days before Barbarossa a huge amount of upgrading needs to be done with upgrading 90 armoured divisions to Arm1943 being the big icd item. Having the CV completed in late july 1942 and having the CAG upgraded in early august 1942 is more suitable.
It was not "a fleet of 30" that was mentioned. It was 3 fleets that could possibly assemble for a total of 30 ships. Hence the only actual stacking penalty is the one fleet of 12 ships.
Stacking penalty does not depend on in how many formations the 30 naval divisions are organised, only battle participation counts.
One is a stacking penalty - this is a penalty for every unit above the first one that you have. I.e. if you attack with 1 division, you do not have a stacking penalty, but for every additional unit you add to the battle, it creates and then adds to a stacking penalty which is applied to every unit.
For naval division every divisions above two creates a stacking penalty of 2%. This is 48% on attack and defence for a fleet of 26. For air units and land units stacking penalty applies only to attack.
