This design is sometimes called the "token failure". With a mass at 70% of the Unity class and only 60% of the power plant, it was not the fast escort and light frigate envisioned. Only six were built, and after the three were destroyed against Orions in "Botock's Little War" the rest were relegated to in system defense until decommissioned. The idea of the light patrol ship was abandoned by the Ane.

Emerald class ships were never refitted or upgraded during their service life. After "Botock's Little War", the three remaining Emerald class ship were relegated to patrol duty in the three major Ane star systems. By the end of their service life all three ships were totally automated.
