Catherine needed an armour. And not just any armour. She needed a specialised one that suited her needs and purposes as an engineer and a pilot, while still being equally effective at combat. As a Mandalorian, it is part of the Resol'nare, the six tenants to have a full set of Mandalorian armour, or beskar'gam.
Beskar'gam are the most distinctive and symbolic part of being a Mandalorian, and these "Iron Skin" as they were called, were crafted with the use of the rare and precious material, beskar or Mandalorian Iron. The material was known to be incredibly resilient, and very valuable. Most Mandalorians usually have their own versions of the armour crafted to their liking. The appearance and colour schemes of the armour deferred from individual to individual, and Catherine took to using a a shade of soot black for hers. She had loaned an assortment of equipment from Mandal Hypernautics, and the the very first included a AT-MP mining vehicle to be used to extract the precious material from the among the many deposits on Concordia.
