}} | The Japanese submarine Ro-102 was a {{sclass-|Ro-100|submarine}} built for the Imperial Japanese Navy during World War II. Design and descriptionThe Ro-100 class was a medium-sized, coastal submarine derived from the preceding Kaichū type. They displaced {{Convert|601|LT|t|0|disp=flip}} surfaced and {{Convert|782|LT|t|0|disp=flip}} submerged. The submarines were {{convert|60.9|m|ftin|sp=us}} long, had a beam of {{convert|6|m|ftin|sp=us}} and a draft of {{convert|3.51|m|ftin|sp=us}}. They had a double hull and a diving depth of {{convert|75|m|ft|sp=us}}.[1] For surface running, the boats were powered by two {{convert|500|bhp|lk=in|0|adj=on}} diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a {{convert|380|hp|0|adj=on}} electric motor. They could reach {{convert|14.2|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the Ro-100s had a range of {{convert|3500|nmi|lk=in}} at {{convert|12|kn}}; submerged, they had a range of {{convert|60|nmi|abbr=on}} at {{convert|3|kn}}.[2] The boats were armed with four internal bow {{convert|53.3|cm|in|1|abbr=on|sp=us}} torpedo tubes and carried a total of eight torpedoes. They were also armed with two single mounts for {{convert|25|mm|in|0|abbr=on}} Type 96 anti-aircraft guns or a single {{convert|76.2|mm|in|abbr=on}} L/40 AA gun.[3] Construction and careerLaid down at the Kawasaki Jyuko on 30 September 1941 and launched on 17 April 1942. Completed on 29 July 1942. Ro-102 was lost after May 1943 whilst on patrol south of New Guinea. Motor Torpedo Boats PT-150 and PT-152 were credited with her loss off Lae, New Guinea on 13/14 May 1943, however this was confirmed later as {{Jsub|I-6||2}}, which survived the encounter.
