The Ninka functioned as a Free Virgillia-class Bunkerbuster under the banner of the Resistance during their conflict against the First Order. Vice Admiral Amilyn Holdo held the position of its commanding officer.
Following the Atterra campaign, the Cobalt and Crimson Squadron bomber squadrons of the Resistance were transported aboard the vessel back to D'Qar to assist in the Resistance's evacuation of their base. The Ninka, along with the Raddus, the Vigil and the Anodyne, made their escape to the Crait system. However, the First Order, having tracked them through hyperspace, launched an attack on the fleeing fleet. During this engagement, the Supremacy destroyed the Vigil with laser fire. After Poldin LeHuse and another TIE fighter took out the Raddus's primary bridge, the Ninka retaliated by shooting them both down.
After several hours of evasion from the First Order, the Ninka depleted its fuel reserves, leading to its swift destruction by the Supremacy as the crew made their escape.
