An item reported that the total losses of the Netherlands Royal Navy in the Dutch East Indies up to 1 March 1942 consisted of 2 cruisers, 7 destroyers, 6 submarines, 2 minelayers, 1 coast defence ship and 31 flying boats. The Dutch merchant navy lost in the same period 30 merchant ships with a total tonnage of around 100,000 tons. The figures since 1 March could not be confirmed but it seemed that all minelayers, minesweepers, patrol boats and motor torpedo boats were unable to leave the Java Sea were lost. The merchant marine lost presumably 75,000 tons including the 17,000 tons tonnage of tankers lost in the vicinity of Java.
