The Covenant CAR-class frigate is a type of ship mentioned in Transmissions, a type of promotion for the then new game, Halo: Combat Evolved. The transmissions are directly linked to the Cortana Letters and are considered because of their inclusion in the Halo Encyclopedia. Absolutely nothing is known about the dimensions and features of the ships, in fact the only thing ever mentioned about the ships are the following: • CAR Contrition (DE H c-5) Through war we will teach your heresy. Through battle we will teach your frailty. Through death we will teach your fate. • CAR Penance (DE H c-4: OB)
