This is a datagroup of Rigellian Protectorate Space Arm (RPSA) Light Cruisers. This model is an original design by Todd Dillen, based on Jack Southerland's Starfire artwork that is found in the Classic Starfire (Third Edition) products.
This datagroup is sprued to reduce the price for versatile plastics.
