The 1TLs were not significantly different from peacetime designs and were intended for economical use after the war. The design was standardized by the Ministry of Communications, with assistance from the Navy Ministry, early in 1942, and was based on uniform specifications adopted by several yards prior to the war. They were three knots faster than their prewar Allied counterparts and had greater capacity.

Two units were converted to merchant/escort carriers.
