is a comprehensive online encyclopedia and reference resource dedicated to the naval history, ship specifications, and fleet compositions of the world’s navies, with a significant and highly detailed focus on the United States of America .

Before dissecting the US section, one must understand the source. Navypedia is not a glossy, government-funded museum site. It is a passionate, obsessive, and sometimes painfully meticulous project born from post-Soviet naval research. Unlike commercial databases (Janes, Combat Fleets), Navypedia is a free-to-access, non-commercial encyclopedia.
