| Fate | Sunk. Type B submarine. On the patrol line off Oahu on 7 December 1941 and did not enter the harbor. Missing after 27 November 1943 near Tarawa. A plane from the escort carrier Chenango reported a submarine in that area on 29 November. That report is the usual identification, and it is not certain. |
Laid down, displacement, length, beam, draft, speed, and complement are not stored for each hull, so this table leaves them out.
No photograph of I-21 was found. A file titled Japanese Submarine I-21 shows a bow painted 3, and the 1930 photograph is the minelayer later numbered I-121. This is the photograph of I-19, a Type B submarine of the same class. It is not this boat. Public domain, via Wikimedia Commons.
