Skyburners

The Sky Burners are the "celestial demolitions" fleet of the Cabal. They are mainly based around Phobos, seeing limited deployment on Mars, as their full strength has not yet arrived into the system. In the base game, they are only encountered during the final phase of the Cerberus Vae III and Dust Palace strikes. In The Taken King, they are also found on Phobos and the Dreadnaught. They were originally led by Primus Ta'aun before he was taken. The Sky Burners were ordered by the Emperor himself to board the Dreadnaught and kill Oryx, by any means necessary. They crashed their warship into the Dreadnaught's hull, and are fighting a protracted war of attrition deep behind enemy lines. They can be identified by their light blue armor and brush on their helmets.
