Number of warships in service worldwide

The following table lists numbers of warships in service, by type and by country.

Guide to table

 * The table only counts warships that are commissioned (or equivalent) and active (not under repair).
 * Ceremonial vessels, research vessels, supply vessels, training vessels, and unarmed icebreakers are not included.
 * Surface vessels displacing less than 250 tonnes are not included, regardless of other characteristics.
 * Armed submarines are included.
 * Patrol boats are included, even if they work for a force separate from the country's navy (for example, the Medium Endurance Cutters of the United States Coast Guard).
 * The "landing ship" category includes dock landing ships and amphibious transport docks.
 * The "anti-mine ship" category includes minesweepers and minehunters.
 * The "missile sub." category includes ballistic missile submarines only. Cruise missile submarines are counted as attack submarines.
 * Vessels are categorized by size and purpose in accordance with the most broadly accepted definitions. For example, some large frigates may be counted as destroyers.
 * Totals are approximate: data on some countries' brown water forces may be scarce.
 * The ranking of countries is partly arbitrary. Generally, total tonnage of ships is more important than total number of ships.
 * The vessels are grouped into three main types (indicated by colors): red for carriers, green for combatants, and blue for submarines.
