}} | The Japanese submarine I-174 (I-74, until 20 May 1942) was a Kaidai type of cruiser submarine of the KD6B sub-class, built for the Imperial Japanese Navy (IJN) during the mid-1930s. Design and descriptionThe submarines of the KD6B sub-class were essentially repeats of the preceding KD6A sub-class. They displaced {{Convert|1785|LT|t|0|disp=flip}} surfaced and {{Convert|2564|LT|t|0|disp=flip}} submerged. The submarines were {{convert|105|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. They could reach {{convert|23|kn|lk=in}} on the surface and {{convert|8|kn}} underwater.[2] On the surface, the KD3Bs had a range of {{convert|10000|nmi|lk=in}} at {{convert|16|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|120|mm|in|abbr=on}} deck gun for combat on the surface and two {{convert|13.2|mm|in|abbr=on}} anti-aircraft machineguns.[3] Construction and careerShe completed eight war patrols during the Pacific War. She attacked Convoy GP55 on 16 June 1943. During her ninth war patrol, she was sunk near Truk on 12 April 1944 by a United States Navy B-24 Liberator patrol aircraft from VB-108.
