The Juneau class against kamikazes and early jets

Did the Juneau-class anti-aircraft cruisers arrive too late to matter, especially once jets appeared?

They were late for the war as fought, but would have been valuable off Japan, and their guns could still threaten early jets forced to approach within range.

The class is presented as an American response to the need for more 5-inch/38 anti-aircraft fire after the kamikaze threat. Had the invasion of Japan occurred, accelerated ships equipped with 3-inch/50 batteries could have been powerful escorts. Early jets were not inherently too fast for radar-directed 5-inch fire with proximity fuzes; the decisive limitation was whether aircraft could release stand-off weapons before entering gun range.
