I found this detail from Douglas E Campbell's book U.S. Navy, U.S. Marine Corps and U.S. Coast Guard aircraft lost during World War II:

On 16 June, [West Virginia] was firing an assignment for the 1st Marines off southwestern Okinawa when her spotting plane, a Vought OS2U Kingfisher, took hits from Japanese anti-aircraft fire and headed down in flames, her pilot and observer bailing out over enemy-held territory. Within a short time, aided by Putnam (DD-757) and an LCI, West Virginia closed and blasted enemy guns in an attempt to rescue her plane crew who had "dug in for the day" to await the arrival of the rescuers. The attempt to recover her aircrew, however, was not successful. {note: I have also found this passage verbatim in Robert Martin's book on the West Virginia- I am not sure if Campbell plagiarized or the other way around}

This forum post has some more information on the plane, including the names of its crew and some clippings from period newspapers about the incident.
