2 September 1943:
Around 9700, Cdr Tanaka sights a convoy of three transports, escorted by four destroyers and fires two torpedoes. Both explode at the end of their run close astern of the attack transport USS FULLER (APA-7), carrying the Third Division of the New Zealand Army Expeditionary Force from Vila Harbor, Efate, New Hebrides, to Point Cruz, Guadalcanal. A destroyer attempts to counter-attack the submarine, but fails to locate it.

Struck by a single torpedo to starboard amidships, NAVAJO explodes and goes down by the bow in two minutes at 14-58S, 169-17E. A total of 17 sailors are lost; the survivors are rescued by the minesweeper YMS-266. Cdr Tanaka misidentifies his target as a British ACHILLES-class light cruiser.

The Americans invade Tarawa and Makin Islands. The invasion fleet of 200 ships includes 13 battleships and 11 carriers.

21 November 1943:
I-39 is ordered to proceed to Tarawa in the Gilberts with I-19, I-35, I-169 and I-175. Departs Truk on her second war patrol for the area SW of Tarawa, carrying an E14Y1 "Glen" floatplane.

24 November 1943:
I-39 reports approaching her prescribed area.

25 November 1943:
At 0330 (JST), Cdr Tanaka reports his arrival at prescribed patrol sector. This is the last message received from I-39.

That same day, I-39 is reassigned to SubRon 1's SubDiv 2.

26 November 1943:
80 miles SW of Tarawa. At 2252 (Z-12), USS MASSACHUSETTS (BB-59), steaming with Task Group 50.2, makes a radar contact with a surface target at 9 miles to SW. At 2302 Cdr (later Admiral/CincPacFlt) Ulysses S. Grant Sharp's USS BOYD (DD-544), is detached to investigate the contact. At 2320 the destroyer detects a surfaced submarine and closes the target. After the radar contact is lost, BOYD locates the submarine with her sonar. Two depth charge patters are dropped. Fifteen minutes after the last attack at 00-31N, 172-16E, a loud underwater explosion is heard. On the following morning the aircraft from USS ENTERPRISE (CV-6) report a large oil slick in the vicinity. [1]

20 February 1944:
Presumed lost with all 96 hands in Gilberts area.

30 April 1944:
Removed from the Navy List.


Authors' Notes:
[1] While Theodore Roscoe (1960) credits USS GRISWOLD (DE-7) with sinking I-39 off Koli Point, Guadalcanal on 23 December 1943, that location does not match the submarine's patrol area.

USS RADFORD (DD-446) attacked a submarine (possibly I-39, I-40 or I-19) on the evening of 25 November, while she (just like USS BOYD) was escorting TG 50.2.

Special thanks for help in preparing this TROM go to Dr. Higuchi Tatsuhiro of Japan.
