Welcome to Section 22 Week’s Sixth & Concluding Post

Welcome to the sixth and final Chicagoboyz post (Feb 24, 2021) in the “Section 22 Week” count down to the 24 Feb 2021 premiere of the Bilge Pumps podcast with the Section 22 Special Interest Group e-mail list. Today’s post will include slides 72 through 82 of 82 of the Section 22 Powerpoint information packet.
These “back up slides” slides cover Section 22’s interactions with the US Navy over IFF and the utter disaster of the capture of the submarine USS Darter’s technical library by the Imperial Japanese Navy in October 1944.
You won’t find that disaster in any US Navy institutional history, classified or unclassified, on what the US Navy lost that day.  That is not how institutional histories work.  Institutional histories are all about glorifying the institution and its leaders while naming scapegoats and throwing shade at other institutions, with the classified histories detailing the “shade.”  That is why you have to go to the declassified US Army ULTRA history “SRH-254 THE JAPANESE INTELLIGENCE SYSTEM MIS/WDGS 4 September 1945”, to find any details on the  Japanese haul of intelligence from the grounded US Navy submarine USS Darter.

   “One of the most important discoveries of captured documents was made
by the Japanese Navy from the U.S. submarine Darter, which ran aground
west of Palawan on 23 October. The Japanese recovered many documents
    dealing with radar, radio, and communications procedure, as well as
    instruction books, engine blueprints, and various ordnance items.


It is difficult to evaluate the intelligence which the Japanese have
obtained from documents, but in those cases here it has been possible
    the information has been found to be relatively accurate.


USS Darter (SS-227) grounded on Bombay Shoal off Palawan on 4th patrol, 24 October 1944

Figure 1: USS Darter (SS-227) grounded on Bombay Shoal off Palawan, the Philippines on 4th patrol, 24 October 1944. The shell holes from a Japanese destroyer, several US Navy submarines, and a Japanese air attack. This included 55 point-blank hits from the 6-inch deck gun of the Nautilus (SS-168) on 31st October 1944.  Unfortunately, Darter was boarded prior to that shelling by an away team from a Japanese destroyer and the entire unburned contents off her classified  technical library were seized for analysis by Imperial Japanese Naval Intelligence. Visible on the top of the conning tower are the undamaged radar, radio and identification friend or foe antenna’s.

  1. These are the final Section 22 Week social Media cross posts:

    Finally, the thread reader roll up is at the link so you all can see the slide thread all in one place and download the thread as a PDF.

    The PDF costs a premium membership for the app. I get nothing from it.

    The app has been useful to me that throwing them an income stream is the least I can do for their efforts.

  2. Do we know wny the crew of USS Darter were not able to destroy any of the documents? Was there a protocol for doing so? The grounded sub riddled with shell holes suggests a desperate situation. Nonetheless, not letting the Japanese capture that information should seemingly have been a priority.

  3. Lex,

    Cmdr McClintock sent a separate classified letter detailing what was left behind that may be with the Navy Heritage Command in the Washingt5on Navy Yard.

    It was not in any NARA or AFHRA finding aid that the Section 22 list reviewed.

  4. Lex

    At pages 216-217 of the on-line logs of USS Darter, Commander McClintock made the following remarks:

    1. Demolition Outfit: It is recommended that a permanent wiring system for the demolition charges be installed on each submarine at the earliest practiable date. Conditions such as those encountered by the Darter call for this. With lightening the ship, destruction of gear installations below decks, and fires burning, the flimsey wiring provided may easily be damaged; and the wiring available to rig the charges may easily be inadequate, if the ship is left in the presence of the enemy in circumstances where it cannot be sunk.

    2. Classified Matter: It is recommended that the number of registered publications carried on board be further reduced. Also that all confidential files except essential letters be turned in prior to departure on patrol. The time taken to burn all the registered publications and confidential charts, let alone ordinary confidential letters, makes this of vital importance.
