Duraframe

Duraframe is an Enclave-based model name for the designation of a combat-model eyebot series, the assets of which were later diverted to the Hellfire armor project.

Background
The designation of combat model Eyebots were researched as part of a project at Adams Air Force Base. Discontent with the speed of the project's development, Colonel Augustus Autumn ordered the project to be hastened by Dr. Grant, a senior researcher on the project. After a confrontation between Dr. Whitley and Dr. Grant, the project's assets were transferred to the development of Hellfire armor.

In protest, Whitley sent Enclave Duraframe Subject E, the prototype and final functional model in the Duraframe Eyebot series, on a journey to the Navarro outpost. Along with an audio log intended for Narvarro scientists, Whitley included several databanks on the machine, representing the sum of the results of his research on the Duraframe Eyebots along with research into Poseidon Energy and the company's projects in the Mojave area.

The Duraframe model is resilient, ED-E having been was struck by a .308 round, which the Courier notes would have destroyed most robots of the same size. Arcade Gannon mentions that the robot lives up to its model name, having successfully traveled over 2,000 miles. Should ED-E be repaired and activated, the information has the potential to allow the Mojave Brotherhood of Steel to create their own army of Duraframe Eyebots.

Behind the scenes
Joshua Sawyer stated that Duraframe is a model type, not a specific material.
