Cruiser
Older cruisers were called battlecruisers. They used large cannons like most other ships when they were first used but have evolved to use the same weapons and technology as modern destroyers. Cruisers were first built around 1915 but became popular among navies in the early 1930s and are still used today. Cruisers have changed over time and have evolved from the old, large, coal-driven ships to the modern smaller, stealthier, and more efficient vessels. Cruisers are still used today but are very different from the older ones. After battleships stopped being used during the Cold War years, due to being designed around large guns, which by then were beginning to be considered obsolete, cruisers were left as the most powerful surface combatant ship. (Not counting aircraft carriers.) Like with most ships, they are most likely to become stealthier, more efficient, and have more advanced weapons in the foreseeable future.
