Which U.S. aircraft carrier was the smallest one still commissioned during the 1960s?

The smallest U.S. aircraft carrier still commissioned during the 1960s was the USS Langley (CVL-27). Commissioned in 1943, it was a light aircraft carrier that served primarily during World War II and continued to operate into the 1960s. Its smaller size and displacement compared to fleet carriers made it less capable in terms of air operations, leading to its eventual decommissioning in 1970.
