The YF-29 Durandal (YF-29 デュランダル YF-29 De~yurandaru) is a high performance variable fighter first seen in Macross Frontier Movie: The Wings of Goodbye. It was specifically designed to counter the Vajra during the Vajra War and is a sibling unit to the VF-25 Messiah.

In A.D. 2048, the Vajra threat became apparent to the New United Nations Spacy as a result of the Gallia 4 incident. To combat the Vajra specifically, the YF-29 was developed in secret with the intention to exceed capabilities of the YF-24 Evolution, a more general purpose next generation variable fighter being developed at that time. Hence, the YF-29 Durandal became a sibling unit of the similarly designed VF-25 Messiah in which LAI Corporation and the Macross Frontier fleet engineers played a central role.
