Projects HAYABUSA and MJOLNIR were conceived wholly independently of each other to solve a common problem: the creation of self-contained powered armor suitable for use by augmented warfighters. However, the two projects mirror each other, with the UNSC Ordnance Committee eventually requiring many components be cross-compatible. The stealth and stylistic features of HAYABUSA remain a key technical and marketing differentiator, as demonstrated with the Sigma Dragon reconnaissance module, which provides a range of cutting-edge reconnaissance and surveillance functionality with minimal impact on the suit's emission profile.
