[1] HA-101 class boats (except those built by Mitsubishi)
were laid down and launched at Senshu yard (Tanagawa), but then transferred to
Kobe yard for completion.
[2] Sources are divided on the HA-101's fate. Some have her scuttled off
Shimizu in October 1945.
Special thanks for help in preparing this TROM go to Dr. Higuchi
