I added a Sea Port near Iceland which works as the Murmansk route so when USSR join the war they can get Convoys by that route (or Axis can sink them) to get additional Production Points.

Great! How much income will this amount to?

Are you going to include the southern route into Russia as well? Name escapes me? Astrakhan? Pretty sure I read that more resources reached Russia via the south than via Murmansk.

We only plan on the Murmansk route because we have too small map to consider the southern route. The amount is significantly large for USSR and also stretches the Atlantic for UK to cover, means there is now a great area for Axis subs to find convoys.

Yes thats fine. The Murmansk convoys were an important part of British/Allied war effort. More for propaganda I believe but still significant I suppose. Also opens up the possibility of naval activity in the north.

Err, historically, didn't 90% of US-USSR Lend-Lease supplies come through Murmansk and Archangelsk?

They sure as hell didn't come in through Vladivostok...

some came from the Persian route through the caucasus

Historically about 50% DID come through Soviet Asia - millions of tons of steel, aluminium, railway irons, etc, were much easier to ship from the US West Coast on Soviet ships that the Japanese didn't attack because they were neutral! See http://www.o5m6.de/Routes.html

very nice site. I had seen it before but not that part. Well we have the "off map" to take that into account to an extent. Perhaps it should be increased slightly and this decreased but it is at least represented.

For the record, 23.8% of all lendlease aid sent to USSR during WW2 went through Persia which was invaded by both UK and USSR to secure this vital route.

For the more mathematically inclined, that's 4,159,117 tons through the Persian Gulf.

Sound insignificant?

Well, there's another myth blown to pieces!

Thanks for correcting my misunderstanding on this important point
