About the submarines, the ones involved in the original operation K were: I-9, I-15, Iku, I-23 and I-26. Iku, I-15 and I-26 were to refuel the flying boats, I-9 acted as radio beacon, while I-23 provided search&rescue and gave weather reports stationed south of Hawaii. Between the involved submarines I-26 stands as the second highest ranking I-boat. I-9 is the only non Type B1 boat, she was part of the older Type A1 series.
