The 3Ds were standardized cargo vessels. They were designed for mass production rather than commercial economy, like the American Liberty Ships. However, they were a bit sturdier and faster than the 2Ds, which made them a bit less vulnerable to submarines. They had a single island aft of their four cargo hatches.

Only one of these ships was launched in 1945 before the surrender.
