Which ships are commonly referred to as the "greyhounds of the sea"?

The term "greyhounds of the sea" is commonly used to describe destroyers due to their speed and agility. Destroyers are designed for fast response and have powerful engines, enabling them to escort larger vessels, operate in a variety of combat scenarios, and engage in anti-aircraft, anti-submarine, and anti-surface warfare. Their streamlined hulls and advanced technologies contribute to their capability to maneuver swiftly, similar to the grace and speed of a greyhound in a race. This characteristic makes destroyers a critical element of naval fleets, particularly in reconnaissance and rapid strike missions.

Frigates, although also fast, are typically more focused on protecting other ships rather than engaging in high-speed maneuvers. Aircraft carriers are known for their size and ability to launch and recover aircraft but do not match the speed of destroyers. Submarines prioritize stealth and underwater navigation and do not operate at the speeds associated with destroyers.
