Battleships are large, heavily armed warships designed for naval warfare. They typically feature powerful guns, thick armor, and advanced technology to engage enemy ships and provide naval support. Historically, battleships played a crucial role in naval battles, showcasing the might of a nation's navy. The design of battleships evolved over time, with notable examples like the USS Missouri and HMS Dreadnought. However, advancements in missile technology and submarines led to a decline in their use after World War II. Today, battleships are mostly retired, with modern navies focusing on aircraft carriers and other vessels for maritime operations.
