AI Ships can still move around the world - still a disturbing matter

I'm not sure about how it exactly works, however I'm afraid your second guess might be the right one, i.e. the AI can probably base everywhere - which means you'd have to capture every enemy island within 3000 km from your demesne.

Either the suspicion of unlimited naval range is true and then it is useless to capture anything since the AI does not need any bases at all, or what the Devs repeatedly promised is true and AI ships can only move within a certain perimeter from an allied naval base. In both cases you do not have to worry about ports that don't have a naval base.

I'm wondering if 3000 km isn't much too generous a max. range for amphib assaults anyway. Does anyone know what max. distance the U.S. did its leap-frogging in the Pacific?

Hardly. Operation Torch was carried directly from the East Coast with no "rebasing" on the way. Troops for the Guadalcanal campaign were carried from Fiji, at least 1500 km away. Saipan was invaded directly while the Carolines and Truk were still in Japanese control. There were no plans nor a real need to invade the Philippines and the invasion was only carried because of McArthur's insistence. If anything, bases were required to secure naval and air superiority in the region to make an invasion possible, not because transport ships had a short range.

In my recent Nat. China game I had the Germans invading Vladivostok in early 1945 while losing badly in Europe. So I loaded an earlier save game as Germany and found the German transport group casually sailing close to the Ivory Coast, on their way to Vladivostok bay. The single German transports (another annoyance still present in 1.08) all were based in Aalborg. Germany is allied with the historical bunch of European minors + Vichy France, but not with Japan. Axis naval bases closest to Vladivostok are in the Mediterranean and ports in Vichy-controlled Madagascar/Reunion, still over 6000 km from Vladivostok.

So it seems that AI transport fleets do not have range limits. I can upload my saves if devs (if there's any around...) or someone else is interested.

that would require both a REALLY dedicated submarine campaign by the Japanese player and virtually no opposition from the US player. But anyway, I was really only bringing that up because ...

I know... I was only trying to explore the humorous side. Midway and Wake are really good staging areas. I liked how somebody else in similar stacking limit discussion which announced that about 157 divisions shared a province during Battle of Kursk, candidly retorted, "I can live with a stacking limit of 157".

But Amallric poses an interesting question: Can troops starve to death before all convoys get eliminated? I was always of the impression that if a convoy needed, say 25 convoys, got attacked and had 1 convoy sunk; the remaining 24 convoys - being below the minimum required - do not deliver. This one can notice with manual convoy control.

Of course, the solution is to make the convoy bigger by the worst expected losses. However, if anybody failed to do that, and every day the convoy suffered losses, then nothing would deliver I think, so maybe it is possible to starve to death while one still has convoys. Of course this would require nearly "novice game play" to fail to increase convoy size greater than the minimum.

On the other hand, Mr_BoNarpte playing Germany claims he did starve to death the garrisons in Gibraltar and Malta. Maybe he sunk all the UK convoys (?). But they are building more all the time. So, it seems, practically speaking, as one gets seriously low on convoys, priority choices will decide who starves and who doesn't because the limit will be reached where the remaining convoys can no longer alternate fast enough between all the needed destinations to keep everybody in supply.

Yah, it would need to be a really dedicated sub campaign which includes a successful campaign against the US surface fleets (or there would be no more Japanese subs). In that case, doubt you would be having 50 divisions stacked on Midway. But does something similar not actually happen as regards the AI doing it? I have seen several examples of AI stacking on islands so great it is nearly impossible to amphib them. I have had to first build up airbases and then rotate up to a dozen different amphib stacks to keep the attack going for weeks to finally win, and add huge SAG to get every plus modifier possible. Seems just forgetting about such an enemy concentration and just blockading the island (so they cannot get in transports to use the troops) might be more efficient than I did. Maybe they will starve to death if one makes a dedicated sub campaign. But not sure how anyone might ever get the USA down to where they could not replace their convoy losses without attacking the continental states first. The convoys will stop once one has every coastal province. Either way, the USA is a bit like a nut that can be cracked nicely if employing a proper nutcracker, and failing that, just smashing with a brick might work too.

This is true, but the AI replaces sunk convoys really fast, so the interruption is minimal. I have always thought that adding a "cool-down" period to the action of adding convoys to a fleet would be a simple and efficient way to make convoy warfare much more realistic.

This also happens when an AI has too many overseas trades and does not merge them.

Add in a new slider for auto-convoys to use more ships than neccessary and this would be an easy upgrade for 1.09

In both cases you do not have to worry about ports that don't have a naval base.

There is a difference between transport fleets and "regular" fleets.

@Kovakanki: There is no need for a save, the bug is well known.
