The Japanese submarine I-73 was a Kaidai type cruiser submarine of the KD6A sub-class built for the Imperial Japanese Navy (IJN) during the 1930s. One month after participating in the IJN's attack on Pearl Harbor, she was sunk by United States Navy submarine USS Gudgeon.

Design and description

The submarines of the KD6A sub-class were versions of the preceding KD5 sub-class with greater surface speed and diving depth. They displaced {{Convert|1785|LT|t|0|disp=flip}} surfaced and {{Convert|2440|LT|t|0|disp=flip}} submerged. The submarines were {{convert|104.7|m|ftin|sp=us}} long, had a beam of {{convert|8.2|m|ftin|sp=us}} and a draft of {{convert|4.57|m|ftin|sp=us}}. The boats had a diving depth of {{convert|75|m|ft|abbr=on}}^[1]

For surface running, the boats were powered by two {{convert|4500|bhp|lk=in|0|adj=on}} diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a {{convert|900|hp|0|adj=on}} electric motor.^[2] They could reach {{convert|23|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the KD6As had a range of {{convert|14000|nmi|lk=in}} at {{convert|10|kn}}; submerged, they had a range of {{convert|65|nmi|abbr=on}} at {{convert|3|kn}}.^[3]

The boats were armed with six internal {{convert|53.3|cm|in|1|abbr=on|sp=us}} torpedo tubes, four in the bow and two in the stern. They carried a total of 14 torpedoes. They were also armed with one {{convert|100|mm|in|abbr=on}} deck gun for combat on the surface and an {{convert|13.2|mm|in|abbr=on}} anti-aircraft machinegun.^[3]

Construction and career

I-73 participated in the attack on Pearl Harbor as part of the 3rd Submarine Squadron in the 6th Fleet of the IJN. It was one of the vessels created as part of Japan's 1st Naval Armaments Supplement Programme in 1931. On 27 January 1942,^[4] I-73 became the first warship to be sunk by a United States Navy submarine; USS Gudgeon fired three torpedoes at I-73 and destroyed it.^[5] Gudgeon claimed that the torpedoes only damaged I-73, but Station HYPO confirmed the loss.^[6]
