The medical variant of the Pelta-class frigate was painted with the characteristic red markings of the Republic Navy. In appearance, the class bore similarities in design to CEC's CR90 corvettes and DP20 frigates, and had a command tower similar to Consular-class cruisers. Medical frigates of this type were equipped with at least 4 escape pods.
In order to maneuver more smoothly through space, the frigate was capable of opening up a set of wings to expose smaller auxiliary engines. The wings were usually folded up to minimize the ship's profile. The interiors could easily be switched out to conform to different mission assignments in a matter of hours.
The frigates had heavy armor, as well 2 light turbolaser batteries, 3 point-defense laser cannon batteries and 3 tractor beam batteries to defend themselves with. The cargo variant sported gray hull plating, contained a large interior for transporting supplies and, unlike the medical frigate, was armed. An example of this frigate was TB-73.
The Pelta-class was often used in conjunction with MedStar-class frigates, leading to them often being called "medical frigates" despite the modular design.
Republic medical frigates in the vicinity of Naboo were often directed to the Kaliida Shoals Medical Center, which could support tens of thousands of patients. They became easy targets during the Malevolence's numerous strikes.
Some Pelta-class frigates were still used by the Galactic Empire during the Galactic Civil War.
