According to a 2011 report by the United Nations Conference on Trade and Development, the Greek Merchant Navy is the largest in the world at 16.2 percent of total global capacity, up from 15.96 percent in 2010 but below the peak of 18.2 percent in 2006. The country's merchant fleet ranks first in total tonnage (202 million dwt), fourth in total number of ships (at 3,150), first in both tankers and dry bulk carriers, fourth in the number of containers, and fifth in other ships. However, today's fleet roster is smaller than an all-time high of 5,000 ships in the late 1970s. Additionally, the total number of ships flying a Greek flag (includes non-Greek fleets) is 1,517, or 5.3 percent of the world's dwt (ranked fifth globally).
