SENSUIKAN!Stories and Battle Histories of the IJN's Submarines(Updated 1 December 2020)By Bob Hackett and Sander Kingsepp |
The Tabular Records of Movement (TROMs) for the IJN's submarines - "Sensuikan" - on these pages were prepared by Bob Hackett and Sander Kingsepp from Japanese and American source materials. They include TROMs for Japan's largest class "A" submarines - the so-called I-Boats and medium class "B" RO-Boats.
Every effort has been made to provide the latest verified information on their movements and fates. Nevertheless, the nature of submarine warfare sometimes precludes positive identification of the exact time and place of losses at sea. In such cases, we have indicated that the best information available - both Japanese and American - indicates a probable loss at the date and time given.
Feel free to post any questions to me or Sander on the Discussion & Questions board. - Bob Hackett.
"For any author attempting to write about Japanese submarines and their operations during the Second World War one source above all others has consistently and reliably assisted this writer, making sure my dates, specifications, movements and skippers are all recorded correctly within the overall story. This is Bob Hackett and Sander Kingsepp's www.combinedfleet.com, a labour of love for the subject that is an invaluable reference source for researchers, filling in many of the gaps caused by the paucity of written material on Japanese submarines."
-DR. MARK FELTON, author of THE FUJITA PLAN: Japanese Attacks on the United States and Australia During the Second World War and YANAGI: The Secret Underwater Trade between Germany & Japan 1942-1945
"....of particular interest to those researching (Japanese) submarines is www.combinedfleet.com/sensuikan.htm by Bob Hackett and Sander Kingsepp."
-ROBERT C. STERN, author of THE HUNTER HUNTED: Submarine versus Submarine: Encounters from World War I to the Present
"...SENSUIKAN! by Bob Hackett and Sander Kingsepp, provided invaluable operational history of Japanese submarines in World War II, with over 200 initial submarine Tabular Records of Movement (TROMs) that were stories and battle histories. The TROMs, regularly updated, are helping fill in numerous historical balanks and connect World War II events and people from the two former enemies."

"....Love the site - it's proved very useful."

Please see the Bibliography of sources for the SENSUIKAN! pages
Mr. Robert Hackett is a military historian and researcher. Retired from the United States Air Force and later from the aerospace industry, he resides in the United States.
Mr. Sander Kingsepp of Estonia is also a military historian and researcher. A talented linguist, Sander's translations of Japanese source materials have added immeasurably to these TROMs.
Bob and Sander prepared the TROMs on the IJN's submarines presented on the SENSUIKAN! pages and for the IJN's battleships and cruisers presented on the SENKAN! and JUNYOKAN! pages and are major contributors to the TROMs of various classes of auxiliaries and regular small combatant vessels detailed on TOKUSETSU KANSEN! and its related pages.
