The 3As 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 2As, which made them a bit less vulnerable to submarines.

Only one of these ships was launched in 1945 before the surrender. The Tobata Maru, which was completed on 15 May 1945, survived the war.
