      @RogerCooper Here are Merchant Marine figures derived from Ellis, with some extrapolation and assumptions. Figures are in 1,000's of tons. Note that there are no figures on German merchant losses and production, so I just extended the 1939 figure. Note that the US produced an incredible number of ships in 1943, 11,448,000 tons.

        @RogerCooper This may be a good reference, but I think there are some major problems with those data, that need to be addressed:

        • As there is only the year, are those the values at the start of the year? Measures of flux, like losses and production, would refer to a whole year, but measures of stock would be a point in that year. For example, to obtain the start 1943 stock of ships you would need to sum the 1942, but not the 1943, gains and losses.

        • It is not clarified what these "tons" are. Are they "gross register tons" (in this case, not actually weight, but volume), or something else, and, in this case, are they metric, British or US American (if any differences)? Are they all the same metre or just the figure for each country, in the tonnage metre used in that particular country? I also wonder if all the countries in the world, at that time, used to define tonnage the same way, or there were differences.

        • Do they include all ships, or some ships above some minimum tonnage, and how about ships locked in lakes that do not connect to the sea (mainly the Great Lakes merchant fleet of the USA)?

        • (as you say) The figure for Germany is simply the one of 1939 (I would rather leave the entries for the following years empty).

        • It is missing Norway (that, according to my data, was the 4th biggest merchant navy in the world, in 1939).

        • It doesn't specify if it does or doesn't include the losses from interned or captured ships or the gains from captured ships. In particular, the case of France, going through the armistice, the civil war, the undeclared war with the Allies (mostly Britain), the cessation of the armistice and the occupation of Free France, and the case of Italy, that lost a great quantity (about 1/3 of the total tonnage) of ships (interned), right after declaring war on France and Great Britain.


        These are the 1939 only values, from an atlas originally printed in 1945:

        Merchant Navies given in "tonnage", that I assume being what is now defined as "gross register tonnage", in cubic feets, tho I'm not sure about any of this, as it is not clarified. Also, it is not clarified if these are actually the values at the start of 1939.

        Country Merchant Navy tonnage*, in 1,000 tons, in 1939
        United Kingdom of Great Britain and Northern Ireland 17,984
        United States of America 11,874
        Japan 5,630
        Norway 4,835
        Germany 4,493
        Italy 3,448
        France 2,953
        Low Countries 2,933
        Greece 1,781
        Sweden 1,582
        Union of the Soviet Socialist Republics 1,316
        Canada 1,305
        Denmark 1,176
        Spain 914
        Panama 718
        Finland 626
        Belgium 408
        Portugal 269

        *including only ships of over 100 tons each

        In the data above, there is not an entry for Commonwealth, that I assume it means the Dominions, and the only British Dominion present is Canada. So, I wonder about that Commonwealth figure, that is almost three times the one I have for Canada only (also wonder about how much of that is in the Great Lakes).

        The only data that is over 10% away from your 1939 data is the one for the United States of America, that I've at 11,874, while you are giving at 8,910, I wonder if this may be because of not taking into account the Great Lakes fleet or maybe because of a different metre.

          @Cernel In particular, at start 1942, the value for France should be split between the ones under Vichy control, the ones under Free French control (or are they counted as British?) and the ones interned (no idea how much impactful).

            @Cernel The numbers are for the start of the year. My source, (Ellis, World War II, A Statistical Survey), does not specify anything else about the numbers.The omission of Norway was my error.

            USA 8910 9286 9815 10847 13980 24099 32856 38446

            I have no figures on captured and interned ships. A loss of a third seems reasonable, but the overall effect is small compared to wartime production.

              @RogerCooper Well, ok, 4,835 vs 1,987, that is less than half of the value I have, instead.

              I found this article on the Norwegians:

              https://pressto.amu.edu.pl/index.php/fsp/article/viewFile/3613/3645

              In the summer of 1939 the Norwegian merchant fleet had 4 833 813 BRT[1] of tonnage and was classified in fourth place in the world, just after Britain, the United States and Japan (Steen 1959:111).

              1. BRT (Brutto Register Tonne) it is a measure of vessel capacity counted in register tonnes. 1 registered tonne = 100 cubic feet = 2,83 m3.

              So, I think, if that article is correct, either your data is wrong or there have to be something going on there, in the way it is measured?

              Also, as I said, it is lame when a source (mine too) doesn't specifically exactly state what kind of tons or tonnage it is talking about. 1 gross ton in ww2 was 100 cubic feet, but a ton can also be a weight measurement for "displacement tons" and "deadweight tons" and, in this case, it can be either a British, an American or a metric ton.

              As I said, I don't know how Ellis gets the figures, but Italy lost over 1 million tons of merchant ships in 1940, so that figure for start 1941 must be wrong by about 1 million. Also, no idea about how it calculates for after 1943, since, after the surrender, the Italian merchant marine was partly destroyed or captured by the Germans, and only a portion remained under Italian control (now co-belligerent with the United Nations).

              So, that figure is some helpful, but it still has a number of question marks. Something more precise would be needed, for knowing exactly what were the merchant marines in 1942 or so.

                    @Cernel Ellis just lists the 1939 values and specifically invites the readers to extrapolate from the sinking & building figures.

                    For Italy, I simply calculated Italy as a member of the Allies in 1944 & 1945.

                    Ellis puts Axis shipping losses in the Med 187,000 for 1940.
