The Yorktown's radar detected Hiryu's inbound flights.We're giving the IJN shipborne radar and aircraft radios equal to the best then in service in the RN, USN and KM (German naval radar was for FC, so limited here), whilst making them early innovators in CIC and fighter coordination (essentially what the RAF had in 1940). We're not inventing radar or radio tech that wasn't in existence in 1942.
She was able to direct a fighter intercept, stopped SBD recovery directing them up as CAP instead and for all that, she still took hits.
