CL is the US Navy hull classification symbol for a light cruiser — a type of medium warship smaller and faster than a heavy cruiser but with significant firepower. The designation was used throughout the early-to-mid 20th century in the US and other navies. As a pure abbreviation, it belongs to naval and military technical vocabulary. As a dictionary entry its value lies mainly in clarifying this specific naval abbreviation for readers unfamiliar with US Navy hull classification codes.
The fleet included two carriers and three CLs providing escort and anti-aircraft cover.
