Keljiric-pattern Tarasque

The Tarasque-class heavy fighter is an older Covenant Elite-manned starfighter. It was replaced by the new covenant craft, the Seraph. It has so far only been mentioned in the description of the Elite Flight Harness armor permutation.

Though little about the craft is known beyond its name, it appears to be named after the Tarasque, a French monster.

It's possible that this may be the so-called "Covenant Flyer" seen in Halo Wars.
