The N3-S-A1 design was developed on a special request from the British after a visit to the United States. During this visit the British Shipbuilding Mission stressed the Commission, that even more tonnage would be required, if the tonnage of lost shipping was to be replaced and supplemented. With this came the suggestion that the shipbuilding potencial of the Great Lakes be drawn on for the construction of small cargo ships. This was the start to develope the N3-S-A1 for the British, and the transfer of these ships under the Lend / Lease Act. These vessels were typical three-island, two deck ships with poop, bridge deck and forecastle and two hatches in each well. The N3-S-A1 was a coal-burner, ideal for operating by the British. All vessel were sold after WWII, and were converted to oil-burner in 1950-51. They served into the 60's and some into the late 70's, when the last ship was finally scrapped. Well known to Northern Europe and Mediterranean ports, they were quite similar to well known "Norwegian" coasters specially built for the Baltic timber trade.

The N3-S-A2 design was a oil burner instead of coal like the N3-S-A1. The measurement was the same, and their was only small differences in tonnage and capacity. The ships were named like the A1's after captains of famous American clipper ships, although a few were launched with a "Northern" prefix, and transferred to British under Lend / Lease, and some were transferred to Poland and the Netherlands under  Lend / Lease. All vessels were sold after WWII under the Merchant Sales Act of 1946 to foreign interest. A large group were sold to the Nationalist Chinese Goverment in 1946 and the fate of some of these vessels, especially those who were captured by the People Republic Army of China in 1949 is doubtful. Like the A1's the served into the 60's and mid 70's around the globe.
