The Cardassian Aid Armada was a Cardassian fleet within their space forces. During the Years of Deliverance, the Cardassian Union dispatched the Aid Armada to the occupied world of Bajor.
When Gul Atal along with his aide Skrain Dukat were on the planet, the Bajoran Resistance began heavy fighting in order to prevent the investigation of the ruins of the settlement of Bar'trila. No orbital fighters were present to help the Cardassians against the Bajorans which showed that there was no hope of deliverance from the crazed Bajoran fighters. (TOS novel: Captain's Peril)
