Ship project history: The project was developed on IJA order, but control over building and subsequent operation of majority of them realised by IJN. Represented usual cargo vessels adapted for transportation of military cargo and troops. Engine and superstructure took places at aft end, amidships part of the hull has been occupied by two large holds. Fore end had icebreaking form that allowed the ship to come nearer closely to a shore. Beaching was realised through a folding gangway port.

First SS1-3 originally were under Army control and were named. In 1944 they were transferred to IJN and numbered. Remaining ships were transferred under naval control even before completion. At least five ships of the class remained incomplete. Incomplete SS24 was sunk by American aircraft in 1945 at Osaka. Incomplete 23-go was badly damaged at Osaka in August, 1945 by American aircraft and completed later mercantile.

Modernizations: 1944, 1-go, 2-go: - 1 x 1 - 75/44, 4 x 1 - 20/65; + 1 x 1 - 76/40 11-shiki, 4 x 1 - 25/60 96-shiki

Naval service: 17 ships of this class were lost in days of war: SS3 (sunk 27/3/1944 by submarine near New Guinea), SS4 (lost in autumn 1944 in Philippines area), SS2 (sunk 13/9/1944 by American aircraft near Cebu), SS5 (sunk by American aircraft 30/11/1944 near Masbate), SS6 and SS9 (sunk 4/12/1944 by American aircraft off Mindoro), SS1 (sunk 13/1/1945 by American aircraft at Luzon), SS11 (lost in spring 1945 near Shiranoe or Moji), SS20 (ran aground near Shodoshima 20/5/1945, raised 17/9/1945 but lost in storm while under repair, raised again and converted to mercantile vessel in 1946), SS21 (sunk 1/6/1945 by American aircraft near Osaka, raised and used as mercantile), SS17 (sunk by American aircraft 5/6/1945 off Talien), SS13 (August, 1945), SS22 (sunk 8/8/1945 by American carrier aircraft near Aomori). Besides, dates of loss of SS8, SS10, SS14 and SS15 are not known. SS16 was presumably lost in April, 1946 at Yohimi, raised and broken up in 1947.
