Quoting Captain Holmes again how the course of the War was changed the nature of our work:

“The virtual destruction of the Japanese Navy and the drastic reduction in the numbers of marus brought about changes in radio intelligence.  It also forced the Japanese to suicide weapons of many varieties.  Most effective were kamikazes which, in April and May 1945, took off from Kyushu in mass flights to attack U.S. ships in the vicinity of Okinawa.  Kamikazes were the most serious threat the Navy faced during the war.”
